From Professional Meteorologist Bernie Rayno: "Right snow looks like a 1-3" from I-81 in VA northward into eastern New England (includes, DCA, PHL, NYC and BOS). A narrow 3-6" from central and eastern LI to Cape Cod (as islands). Injection of arctic air in place means potential is there for much more if ENERGY is stronger"

Our well below normal temperature wise January continues with only a brief respite Friday and Saturday before the coldest weather of the year arrives next Monday through Wednesday. We finally do moderate to near normal temperatures (upper 30's) by Friday and Saturday. Precipitation wise we have an increasing chance of some light snow tomorrow PM that should accumulate no more than a coating to an inch. Then showers on Saturday before a chance of some light snow or flurries by Sunday afternoon.

Suppression with too much of a good (cold) thing....this reminds me of the winters of my youth in the 1970's cold but below normal snow. It was our least snowy but coldest decade in recorded history!

The follow up storm to Sunday modeled on the Euro

The latest model runs for model snow we will never have to shovel for the potential snow event on Sunday late afternoon and evening are below. Most models have some model snow - the GFS has none! That model remains a possibility.

We are back to below freezing days and nights till Friday afternoon. Maybe some flurries on Thursday afternoon otherwise dry until Saturday. It will warm to close to normal by Saturday and we should see some rain that afternoon. But big changes start on Sunday with the arrival of a strong arctic front on Sunday. With the passage of the front, we may see snow arriving by Sunday evening. Whether it's flurries or a plowable event will be determined in a few more days. Either way the coldest air of the season will arrive by Monday night and last through much of next week. Of historical note on this date back in 1912 the coldest reading in Chester County PA history was recorded at Coatesville 1SW and matched on January 22, 1961 at Phoenixville of 19 degrees below zero.

If the GFS has a clue.....next Tuesday could be our coldest afternoon since Christmas Eve 2022.

GFS focusing on next Sunday evening - Canadian Tuesday-Wednesday....

Today, while closer to normal will be our 24th below normal temperature day over the last 29 days. Our high today should be reached by mid-afternoon. We then see a cold front crossing the area with winds increasing and the temperatures falling below freezing by evening and we then stay below freezing all work week till Friday afternoon. We stay dry this week with our next rain chances by Friday night which could start as a little snow before a changeover to rain.

There will be many more model runs with significant storms.....we have plenty of model snow left to shovel in 2025!!!

Quite the pattern incoming!!!......all of this model snow has broken my snow blower!!

Plenty of potential from days 7 to 10

For the first time in 8 days, we should see a high temperature today above freezing. Tomorrow will also be above freezing but still below average before the cold air returns again tomorrow night and we fall back below freezing until Friday. Our next precipitation chance looks to be next weekend with rain followed by snow chances as we may see our coldest weather so far this winter by next week.
