GFS has sped up the cold air arrival and now has the change to non-liquid occurring during the 4am hour in NW Chester County

That 0.25" of ice would not be great here in NW Chesco and the LV IF the NAM is correct...

Latest NAM is in pretty good agreement now with GFS on timing of FROPA and ZR start as the 0c surface line starts to reach NW Chesco during the 7am hour on Friday

Freezing temps look to be entering Chester County from NW to SE around 7am on the GFS and getting close on the NAM

January was indeed a cold month here in Chester County. In fact we finished with an average temperature of just 26.6 degrees, our coldest January since the 26.2 average temp back in 2015. Overall it was the 35th coldest January since Chester County records began 129 years ago back in 1894. Snowfall wise we finished with 12.9" of snow which is 2.5" above normal. Precipitation (including liquid equivalent snow) was 3.81" which is 0.25" above normal. Seasonal snowfall stands at 12.9" which is 3.8" below our normal season to date snowfall through the end of January which is 16.7"

Agreed in this area it is pretty rare to go the rain to ice to snow route..the cold air will certainly be drilling in by the pre-dawn hours of Friday morning....

The 1 foot line is a bit off as we will finish January with an above snowfall month here (12.9") in NW Chester County and just under 4" below seasonal norms to date...but for sure more to the north and south so a real relative snow hole!!

I do love fake news for fun...just saw ABC National News as always leading with " life threatening storm" impacting blank million people in the mid atlantic and Northeast....they really do have a checklist!!

Of course we must....as that is the way the NWS views these events they are considered one storm.

steady but light snow picking up a bit here in NW Chesco and even paved surfaces getting re-covered with snow as temps slowly fall now down to 28.7

Justin you are correct! my point and click had 0.5" possible by this evening.....snow continues to fall steadily but lightly -latest HRRR looks like we may never stop snowing as the coastal begins to throw moisture back to the west. That said much less snow will clearly fall here in the NW burbs compared to philly and points east!!
