October 29-30 2017 rainfall total map

The tenth month of 2017 was marked by the slow arrival of October-like conditions, including the first freezes of the season, the close-to-two week delay in the fall leaf season, and the absence of much precipitation until two late-month storms made up for lost time. Amidst all of this, October proved to be the second warmest across New Jersey since the onset of records in 1895. The 60.7° average was 6.2° above the 1981–2010 normal, trailing the 2007 record by 1.4°, but 0.9° above the now third mildest October in 1971. The month ended with a large portion of the state yet to be visited by the first freeze of the season.

Rainfall was rather limited throughout the first three weeks of the month, leading to an expansion of D0 “abnormally dry” conditions across the northern half of the state in the US Drought Monitor. It was anticipated that a portion of the north would move to a D1 “moderate drought” designation and the remainder of NJ to D0 come the October 31st weekly map (as mentioned in previous reports, the state climate office plays a significant role in making such designations). However, some welcome rain fell on the 24th, and on the 29th the largest statewide rain event since April 30, 2014, brought close to, and in some areas more than, a month’s worth of liquid in a major storm. This arrived on the 5th anniversary of Sandy and 6th anniversary of a historic early season snowstorm. When all was said and done, statewide October precipitation averaged 4.96”. This is 1.07” above average and ranks as the 25th wettest of the past 123 years.

While remarkable deadly and destructive hurricanes pummeled portions of the Caribbean and southern states, September weather conditions in the Garden State were generally quiet. The most notable exceptions were the dangerous rip currents at the Jersey shore associated with the latter stages of Hurricanes Irma and Jose, which resulted in several drowning deaths and numerous water rescues. Minor to some moderate back-bay flooding and beach erosion accompanied the tumultuous surf, particularly between the 18th–21st. Otherwise, little more than some clouds and light rain reached NJ from these...

Despite July and August typically being the wettest months of the year in New Jersey, their warmth usually results in evaporation rates exceeding rainfall. Thus, when heat ensues and rain is light for a few weeks—not uncommon in a Jersey summer—lawns, gardens, and fields require considerable irrigation to avoid wilting or browning. Such was not the case this past August and earlier in the summer, as rain was ample and quite timely in most areas and hot temperatures did not prevail for extended periods. More will be reported for the summer as a whole later in this report. For August in...

July 2017 proved to be an active month of weather throughout the Garden State. Time and time again, storms traversed the state, often depositing the heaviest rainfall in 30–40 mile west-to-east “corridors,” while elsewhere totals were much lighter. Such is the nature of showery summer rainfall, although in one case, the swath of heavy rainfall was associated with an out-of-season coastal storm. When all was said and done, rainfall occurred frequently enough to leave most locations with average to well above average monthly totals. The statewide average July rainfall was 6.33”. This is 1.76...

Gradual Seasonal Transition: November 2016 and Fall 2016 Recaps

December 8, 2016 - 1:51pm -- Dave Robinson

Snow photo

Much like the entire fall season, the transition into the cold half of the year was in no great hurry in November. Leaves dropped from ten days to two weeks later than normal, but eventually by the 28th the temperature fell to the freezing mark at West Cape May (Cape May County) and Newark Airport (Essex), these being the last locations in the state to experience their first freeze. A major exception to the slowly-transitioning pattern was the moderate high-elevation snowfall the weekend before Thanksgiving.

Drought conditions continued to be worrisome across the state, even spreading southwards. However, back-to-back heavy rainfall events on the 29th and 30th provided some replenishment to thirsty soils and began adding water to surface reservoirs across central and northern counties. It will be interesting to see if the atmospheric pattern change that delivered the late-month soakings is fleeting or will be longer lasting. Monthly precipitation (rain and melted snow) averaged 2.48” across NJ. This is 1.13” below the 1981–2010 average and is the 43rd driest November since 1895. It is worth noting that most of the National Weather Service stations that go into determining this average report in the morning. Thus the rain that fell later on the 30th is not factored into the monthly average; rather, it will be part of the December total. Snowfall averaged 0.4” for NJ but broken into regions amounted to 1.3” in the north, 0.1” central, and 0” south. The statewide total is average for Novembers between 1981–2010 but 0.7” below the 1894–present average.

A Climatological Potpourri: October 2016 Recap

Season transitional months are often known for the wide swings in daily and weekly weather conditions. October 2016 did not disappoint when it came to exhibiting such variability. Moisture associated with a weakening hurricane to the south contributed to south Jersey’s heaviest rain event. A modest late-month storm brought the first frozen precipitation of the season to northern counties. Record warmth for so late in the season was part of a dry mid-month week. Halloween eve seeing the temperature touch 80° in some locations before a thunder-strewn frontal passage dropped temperatures to more seasonal temperatures for trick or treating.

Summer is Slow to End: September 2016 Recap

October 5, 2016 - 4:25pm -- Dave Robinson

Sunrise photo

Summer warmth continued into September, only beginning to relinquish its grip on the Garden State during the last week of the month. The average statewide monthly temperature of 70.1° was 4.3° above the 1981–2010 mean. This ranks as the 4th warmest September going back to 1895, with five of the eight warmest Septembers occurring since 2005. Seven of the most recent 13 months have ranked in the top 10 for warmth in their respective months.

Monthly rainfall averaged 3.36” across the state, which is 0.69” below average and ranks as the 61st driest of the past 122 Septembers. However, as discussed below, the average this month does not show the wide disparity of rainfall between the northern and southern parts of the state. While concerns for persistent dry conditions continued increasing across most of NJ through mid September, two soakings in the south alleviated worries in this region. Meanwhile, only one event of note produced totals exceeding an inch in much of the north, thus this region remains much too dry. As of the 27th, a good deal of north and central NJ was considered in moderate drought, with the remainder deemed abnormally dry according to the US Drought Monitor. North Jersey remained under a NJ Department of Environmental Protection “drought watch."

Top Ten August for Heat and Dryness, Yet Another Hot Summer in the 2000s: August and Summer 2016 Recaps

While above-average temperatures persisted from July into August, the precipitation regime did a 180° reversal between months. A 9th warmest July transitioned to a 2nd warmest August across the Garden State, based on records extending back to 1895. The 14th wettest July proved to be a hydrological blessing following the 20th driest June and preceding the 9th driest August. While August ended with most of New Jersey designated as “abnormally dry” and the northeast in “moderate drought” according to the US Drought Monitor, and north Jersey remained under a NJ Department of Environmental Protection “drought watch,” water supplies would have been in far worse shape come late summer had July been dry.

A Return to Hot Julys After a Two-Year Respite; Awfully Wet Too: July 2016 Recap

The second half of the 2016 NJ weather and climate year began with plenty to talk about. Maximum temperatures were 90° or higher somewhere in the state on 20 afternoons. This, along with many warm nights, helped boost the mean monthly temperature into the top 10, based on statewide records back to 1895. Yet, remarkably, this was only NJ’s 5th warmest July in the past 11 years. The 77.2° mean was 2.2° above the 1981–2010 average.

On 15 July days an inch or more of rain fell somewhere in NJ. This included eight days with greater than 2” in spots and four days where a few locations exceeded 4”. Statewide, the average rainfall was 6.85”. This was 2.33” above average and ranks as the 14th wettest July since 1895. It was the wettest July since 2004, and the 4th wettest in the past 41 years. The northern half of the state (Mercer/Somerset/Union northward) averaged 7.27” (+2.49”, 14th wettest), while the southern region averaged 6.77” (+2.38”, 12th wettest). This all came in a month where the northern half of the state remained classified as being in moderate drought (D1) on the US Drought Monitor, with about half of south Jersey considered abnormally dry (D0). Also, on July 26th the NJ Department of Environmental Protection placed the northern half of the state in a drought watch. These actions were the result of notable rainfall deficits dating back to the early spring, with the warmth of the month exasperating low soil moisture, stream flow, ground water, and reservoir conditions. Clearly, the late-month heavy rainfall in a good portion of the state warrants a re-evaluation of drought status as NJ heads into August.

Rather Dry, but Still Some Storms: June 2016 Recap

July 6, 2016 - 1:58pm -- Dave Robinson

Tipped helicopter

Despite some damaging storms impacting portions of New Jersey on several days and some localized deluges near month’s end, June rainfall came in well below average. The statewide average of 2.36” was 1.66” below the 1981–2010 average. This ranks as the 20th driest June since 1895. Northern and central counties were generally drier than those to the south. At month’s end, the counties from Hunterdon, Somerset, and northern Middlesex northward were classified as being in “moderate drought,” the D1 category on the US Drought Monitor. The counties to the south, through Ocean and Burlington, were in the Monitor’s “abnormally dry” D0 category. June stream flow, ground water, and precipitation levels were all well below average, while reservoir capacities in the north began to dip below average near the end of the month.

Temperatures began on the cool side, but the second half of the month was warm enough to bring the statewide average June temperature to 70.6°, which was 0.5° above average. This ranks as the 30th mildest June on record. There was one minimal heat wave at some inland lower-elevation locations, where temperatures climbed to 90° or higher from the 19th–22nd. However, no location exceeded 93° this month. The dry conditions helped to rid the atmosphere of the previous day’s warmth during the nighttime hours, thus temperatures of 45° or lower were observed in spots on seven mornings.

A Tale of Multiple Seasons Within a Month and an Almost Backward Spring: May and Spring 2016 Recaps

June 7, 2016 - 4:54pm -- Dave Robinson

May 15 graupel photo

May had many weather faces. Cool, damp weeks to start things off, a blustery mid-month day with some frozen precipitation, a week of summer heat, and an early Memorial Day deluge up the New Jersey Turnpike corridor. When all was summed and averaged, the mean monthly statewide temperature came in at 60.0°. This was 0.8° below normal and ranked as the 55th coolest of the past 122 Mays. Precipitation averaged 5.01”, which is 1.01” above average and 23rd wettest.

Rain fell on a number of May days across NJ, keeping vegetation green and fire danger down. It was most plentiful in the southern half of the state, where Mount Laurel Township (Burlington County) totaled 7.74”. This was followed by Mount Ephraim (Camden) with 7.68”, Washington Township (Gloucester) 7.54”, Salem (Salem) 7.41”, Cinnaminson (Burlington) 7.02”, and Estell Manor (Atlantic) and Merchantville (Camden) each with 7.00”. The northwest corner had the least rainfall in May, with just 3.01” in Andover (Sussex) and North Arlington (Bergen), along with Mount Olive (Morris) at 3.04”, Hackettstown (Warren) 3.05”, and Franklin (Sussex) and Wantage (Sussex) each with 3.06”.

Another Dry Spring Month: April 2016 Recap

April continued a dry period that began in March. Monthly rain and melted snow totaled 2.34”. This was 1.72” below the 1981–2010 normal and ranks as the 20th driest April since 1895. The 4.35” March–April total was 3.94” below average and ranks as the 7th driest such interval. Unlike the abnormal warmth of March, the average April temperature of 50.7° was 0.5° below normal. This ranks as the 48th mildest on record.

Statewide snowfall averaged 0.2”, which is 0.7” below the 1981–2010 mean. The southern counties averaged 0.3” (-0.3”), central 0.0” (-0.9”), and the north 0.2” (-1.2”). The 2015–16 snow season ended with a statewide average of 28.0”. This is 4.3” above the 1981–2010 average and 1.8” above the 1895–2016 average. The north was least snowy with 26.5” (-6.5”), the central snowiest at 31.0” (+4.3”), and the south with 27.4” averaged 9.8” above normal. The January blizzard provided the bulk of the snow, well over 75% of the winter total in some locations.

Spring Warmth Arrives Early: March 2016 Recap

April 4, 2016 - 7:53pm -- Dave Robinson

Mild and dry conditions prevailed throughout the Garden State during most of March. This included record-breaking early-season warmth, only one event that dropped more than an inch of rain over multiple locations, and a few minor forest fires. There were also two episodes of measurable snow that focused on coastal counties and 11 days where winds gusted to 40 mph or higher somewhere in the state. The statewide average temperature of 46.7° was 5.6° above the 1981–2010 average. This ranks as the 6th mildest March since 1895. Precipitation averaged 2.09”. This is 2.14” below normal and ranks as the 13th driest March.

March snowfall average 2.4” across the state, which is 1.9” below average. Northern counties saw only 0.8”, which is 5.3” below normal, while the central portion of the state received 1.6” (3.3” below normal). The southern counties were the winners, averaging 0.7” above normal at 3.7”. While snow may fall in April (the morning of April 3rd saw 2.7” at Highland Lakes [Sussex County]), a look at what are likely close to the final seasonal totals includes a statewide average of 27.9”, which is 1.8” above normal. North Jersey took it on the chin, with an average of 26.3”, some 8.4” below average. Central NJ was the winner at 31.0”, 4.0” above normal. Meanwhile the south Jersey total of 27.1” exceeded that of the north, even in an absolute sense, and was 7.1” above normal.

Volatility Reigns: February 2016 and 2015/2016 Winter Recaps

March 7, 2016 - 7:10pm -- Dave Robinson

Fire photo/radar combo graphic

Much like this past January, the second month of 2016 had considerable swings and occasional extremes in temperature and precipitation. This included a brief, exceedingly cold mid-month outbreak with subzero wind chills and a late-month evening with severe thunderstorms bringing strong winds, hail, and flash flooding across NJ. A key indicator of the volatile weather pattern was the wind, which on 13 days gusted to 40 mph or higher somewhere in the state, with five of these days gusting to at least 50 mph. The statewide average temperature was 35.6°, which is 1.8° above the 1981–2010 normal. This ranks as the 19th mildest February since 1895. Precipitation (rain and melted snow) averaged 4.21”. This is 1.35” above normal and ranks as the 24th wettest. Snowfall was below normal, with a statewide average of 5.1”. This is 3.0” below normal and ranks as the 52nd least snowy of the past 122 Februaries. Northern counties tallied only 4.6” (-5.5”), the central region 6.3” (-2.7”), and the south 4.7” (-1.9”).
