Quick Hitting Thump

Last night's snow event brought a quick thump of between 4 and 7 inches for those in New Castle, Chester, Delaware, and Gloucester Counties, with South Philly getting in on the northern fringes of the heavier band.   Snowfall totals in the northern suburbs range from around an inch in Trenton to a couple of inches in Bucks County to 3-4" along the 422 corridor to more than that in Chester County...so far...I'll update this after snowfall totals get reported in later on as people wake up.   As of 5:30 this morning, the highest reported total is 5.5" in Blackwood in Camden County although I would not be surprised if 7" fell in some parts of New Castle or Chester County overnight.





The snowfall total at Philadelphia (6" as of 7 AM at the Airport) has pushed the seasonal total to 44" for the winter --  this is only the second time in Philadelphia's recorded snowfall annals that we've had consecutive winters of 40" of snow or more, with the other instance in 1977-78 and 1978-79.


The dry air definitely lost after 10 PM as heavier snow thumped into the city and southern suburbs, with one inch plus per hour accumulation rates in the above band at 11:30 PM.   Snowfall slowly tapered off after 1 AM from the city on south, with most of the snow exiting stage right and stage south by 4:30 this morning.  If anything, the drier air helped enhance some "fluff" across the heavier band...Philly's total precipitation (melted) was 0.47" -- ratios were just over 12:1 (12" of snow for 1" of liquid water) in Philadelphia with the storm.   However, the cutoff was pretty sharp as Trenton picked up just 1.1" and Bensalem had 2.4".   I would have been better served to nudge the 2-5" band about 10-15 miles north across South Jersey.

In the wake of the snow, expect a chilly day with increasing sun.  It will be breezy at times, adding a chill to the air but with temperatures expected to rise in the mid 30's this afternoon a good bit of the slush and snow on your side street will quickly melt.
