Winter

Upon updating a weather friend regarding February conditions that transpired while they were away from the region, he remarked that most of what I reported appeared to have been more along the line of nuisances, while nothing of a blockbuster status occurred. I agreed, as while there were a few plowable events, one soaker (freezing rain at higher elevations), some cold and mild days, and (like in January) quite a few windy days, precipitation and temperatures came in close to normal and not much occurred that will leave lasting memories. In many respects, this applies to the entire winter of 2024/2025 (December–February), leaving an impression among many that this season had a wintrier feel than recent years. However, it was without a major nor’easter, be one excessively wet or white. Meanwhile, when all was said and done, a statewide drought warning remained in place. This report examines February conditions followed by a winter recap.

Statewide, February precipitation (rain and melted snow) averaged 2.53”. This is 0.33” below the 1991–2020 normal and ranks 50th driest since 1895. The precipitation was quite evenly distributed across the state, although the northwest came in on the drier side. The northern climate division averaged 2.56” (-0.23”, 58th driest), the southern division 2.50” (-0.39, 46th driest), and the coastal division 2.59” (-0.48”, 51st driest).

The first month of 2024 provided a potpourri of weather happenings, including excessive rainfall and flooding, multiple snowfalls, frequent strong winds, frigid days, occasional warmth, and culminating with persistent dismal (aka damp, cloudy) conditions. Something for anyone or perhaps not favored conditions for most people. Totaling up the multiple precipitation episodes, this month emerged as the 6th wettest January on record dating back to 1895. It was the wettest January in 25 years and follows this past December, which was the wettest on record. The statewide 6.39” of rain and melted snow was 2.90” above the 1991–2020 normal. The northern climate division averaged 6.70” (+3.20”, 5th wettest), the southern division 6.18” (+2.71”, 7th wettest), and the coastal division 6.48” (+2.97”, 6th wettest).

January snowfall averaged 7.0” across NJ. This is just 0.2” below normal and ranks as the 53rd snowiest January of the past 130 years. Snow divisions include the north, which averaged 8.9” (-0.5”, 52nd snowiest), central coming in with 5.9” (-1.8”, 65th snowiest), and south with 6.6” (+0.9”, 43rd snowiest).

Temperatures fluctuated throughout the month, ultimately averaging 34.7° statewide. This was 3.0° above normal and ranks as the 20th mildest January. The north averaged 32.3° (+3.4°, 17th mildest), south 36.1° (+2.7°, 22nd mildest), and coast 36.9° (+2.5°, 24th mildest). The statewide average maximum of 42.0° was 1.7° above normal, ranking as the 30th warmest. The statewide average minimum of 27.4° was 4.2° above normal, ranking 16th mildest.

January 2023 was unlike most any first month of the year a New Jersey resident has experienced. Temperatures were similar to those normally seen in March and accumulating snowfall was meager in the north and non-existent further south. NJ weather was more like that of the piedmont of North and South Carolina at this time of year. The statewide average temperature of 41.0° was 9.3° above the 1991–2020 normal and ties with 1932 as the mildest January since records commenced in 1895. The average high of 48.9° was 8.6° above normal, ranking 2nd mildest. The average low of 33.1° was 9.9° above normal, also ranking 2nd mildest. It is indeed impressive to see the January 2023 monthly mean 0.7° warmer than the normal monthly high temperature and the average low was 1.4° above the normal monthly mean. The NCEI northern division averaged 38.8° (+9.9°, rank #1), the southern division 42.3° (+8.9°, #2), and the coastal division 43.0° (+8.6°, #2).

January precipitation averaged 3.65” across NJ, which is 0.16” above normal and ranks as the 45th wettest on record. This includes rain that fell during the PM hours of December 31st, as the clock starts on the new month (and in this case, also the new year) once observations are gathered at most NWS Cooperative stations around 7–8 AM each morning (much as what occurred on November 30, 2022, contributing to December totals). The northern division was wettest, averaging 4.19” of rain and melted snowfall (+0.69”, 31st wettest), the southern division 3.36” (-0.11”, 56th wettest), and the coastal division 3.01” (-0.50”, 78th wettest/52nd driest).

The second month of 2022 and third month of winter continued a theme since December. Whether you call it a see saw, swing, or merry-go-round, it fits the theme of playground equipment as it never seemed any one particular variety of weather became established for all that long. More will be said about winter at the end of this report, but when it came to February, the end result was a somewhat warmer-than-normal month with about average precipitation and a dearth of snowfall. The statewide average temperature of 35.6° was 1.7° above the 1991–2020 normal, ranking as the 19th mildest since 1895. There was an above-average spread between the average high of 46.7° (+3.6°, 12th mildest) and low of 24.4° (-0.2°, 40th mildest), the 22.3-degree range being 3.8 degrees wider than normal. The north averaged 32.0° (+0.7°, 26th mildest), the south 37.7° (+2.2°, 16th mildest), and coast 37.9° (+1.9°, 18th mildest).

Rain and melted snow/sleet averaged 2.93”. This is 0.07” above normal and ranks as the 60th wettest/69th driest. The north averaged 3.45” (+0.66”, 44th wettest), south 2.62” (-0.27”, 49th driest), and coast 2.54” (-0.53”, 44th driest). More geographically specific, the far south was driest and the northwest wettest.

Fate was clearly tempted when last month’s report was entitled: “Pretty Darn Boring.” Not that this wasn’t a truthful statement from both meteorological and climatological perspectives. So now this month’s title, being just as legitimate as January’s. The turnaround began in the waning hours of January 31st when what proved to be an impactful, long-lasting coastal storm began to invade the Garden State. This major event was followed by a series of storms that resulted in record or near record-setting monthly snowfall totals in northern and central regions and quite wet conditions in the south.

Statewide precipitation (rain and melted snowfall) averaged 4.89” in February. This was 2.03” above the 1991–2020 average and ranks as the 14th wettest February in 127 years of record keeping. The coastal south averaged 5.91” (+2.84”), ranking as 6th wettest. The remainder of the south came in with 5.09” (+2.20”, 11th) and the north 4.44” (+1.65”, 19th). More specifically, the southeast and central areas were wettest and the southwest and far north least wet.

While plenty of precipitation fell throughout the state, it was more often than not in the form of rain across the southern third of NJ, while central and northern areas were visited by one major snowstorm and a series of modest ones. All told, the statewide average snowfall was 23.5”. This is 15.3” above the 1991–2020 average and ranked as the 7th snowiest February.
