GFDL/Princeton Area Snowfall Observations (inches)

2023-2024 Season

Amount  Individual Reports Season Tot
06 Jan 2024 0.9 ajb=1.3 cw=0.7 ds=0.7 jpk=M rjs=M wfs=1.0 0.9
Our First measurable snowfall of the season was the result of a storm that developed in the western Gulf of Mexico and moved rapidly east northeastward across the southeastern states as it strengthened. With sufficient cold air in place the precipitation started as snow in the GFDL/Princeton but the snow changed to rain during the afternoon of Jan 6 as the circulation around the deepening storm brought more warm air into our area.
16 Jan 2024 2.3 ajb=1.9 cw=M ds=2.2 jpk=2.4 liz=2.4 rjs=2.4 wfs=2.5 3.2
This snow event was the result of a weak storm that developed in the eastern Gulf of Mexico moved east northeastward off the SE US coast and continued northeastward.
19 Jan 2024 3.9 ajb=3.7 cw=M ds=4.5 jpk=3.8 liz=M rjs=3.1 wfs=4.5 7.1
This snow event was caused by a weak storm in the Tennessee Valley Thursday evening, 1/18, moving east northeastward off the mid-Atlantic coast by Friday AM and then continuing out to sea. The precipitation shield extended well to the west into a strong cold air mass. The very cold air aloft supported a powdery snow event with about a 15:1 ratio of snow to water equivalent.
13 Feb 2024 2.9 ajb=4.0 cw=3.1 ds=3.5 jpk=2.7 liz=1.3 rjs=1.4 wfs=4.2 10.0
This snow event was the result of a storm that tracked east northeastward across the Tennessee Valley then re-developed and deepened off the DelMarVa coast. It then continued moving east northeastward. Precipitation started during the evening of Feb 12 as rain and changed over during the early morning of Feb. 13. Location of heavy snow bands produced variability of snowfall amounts across the Princeton region.
17 Feb 2024 5.0 ajb=9.4 cw=M ds=3.8 jpk=M liz=M rjs=3.0 wfs=3.7 15.0
This snow event was from a storm located near western VA during the evening of Feb 16 that moved mostly eastward to be located around the DelMarVa early morning Feb17. The storm produced a powdery snow to the north and a particularly heavy snow band developed well north of the center over Upper Bucks in PA and across Hunterdon, Somerset and parts of Middlesex counties in NJ. This produced significant variability of snowfall amounts across the greater Princeton region. (It should be noted that GFDL’s C-Shield model run at 00Z Feb 17 did a good job at capturing this very heavy snow band for early AM Feb 17.)
