The GFS with it's 1 - 2 punch for our next model snow event. Model snow we will never have to shovel

We have only recorded 11 snowstorms over 6" here in the last 10 years in Chester County. On average based on history we should have seen 15 such storms in a 10 year period. Below are the 11 snowstorms recorded here in Chester County over the last 10 years with greater than 6" of accumulation at a Chester County Station. 1/23/16 - 27.4" / 2/3/21 - 16.6" / 3/22/18 - 13.5" / 3/7/18 - 11.5" / 2/13/24 - 10.5" / 12/17/20 - 9.3" / 12/14/25 - 8.8" / 3/14/17 - 8.0" / 2/18/21 - 7.5" / 11/16/18 - 7.3"

Here in EN we have received 0.77" of rain since Friday. We turn back to near normal temperatures for January with highs both today and tomorrow near 40 degrees. We turn a bit milder for both Tuesday and Wednesday before we turn colder on Thursday with increasing chances of our 9th winter event towards the end of this work week. I would also keep an eye on some possible snow showers or a heavier snow squall this afternoon not too long before Eagles kick off - go birds!

Not a huge believer in even the ensembles at 5 days....I will be more interested in this thread the needle potential if they start to show something at 12z tomorrow.

18z GFS with a Chesco Special..... book it dano!

A needed wet day ahead with rainfall amounts approaching an inch in some lucky areas. It will be chilly with temperatures in the upper 30's to lower 40's. The sun returns tomorrow but don't be surprised if you see a couple snow showers around before the Eagles game at 430pm. Temperatures will be seasonably chilly this week with the exception of Wednesday which looks to be well into the 40's to near 50 for highs before we turn much colder to end the week. There will be increasing chances of some wintry events at some point late this week and early next week.

The 6z GFS before it dissapears at 12z

Plenty of storms and rumours of storms coming up....give me the cold and one of these waves will sharpen just enough for a winter "event" or 2....

Mild temperatures continue today with rain chances increasing this afternoon. A brief break in the rain tonight before we turn chillier with more rain tomorrow into Saturday night. Temperatures turn colder after Sunday with temperatures not too far from normal for mid-January before trending much colder by the end of next week into the weekend. We could see between 0.75” to 1” of rain tomorrow night. Winter weather opportunities start to ramp up by later next week.

valley spots around me were in the 20's but mid 30's here

Some folks had asked me to perform an analysis of both the Winter and Summer Average Temperature by Complete Decades for just here in Chester County from the 1900's thru the 2010's. You will see the very cyclical nature of our warming and cooling patterns. Overall, we have seen some slight warming of winters and conversely some cooling of our summers across Chester County PA. The warmest decade for both summers and winters was way back in the 1930's. Of note so far here in the partial decade of the 2020's we are so far running as the warmest winter decade since the 1930's!! However, last winter was the coldest winter in 10 years and we are off to a colder than normal start to this winter so we will wait and see if this is the start of the next cooling trend across the County. These are also updated on the http://www.chescowx.com website. Let me know if you have any questions.
