Then the vort in the west states ion the previous panel comes calling.  A bit north for an all out snow but tracking pants/shorts required.  All of this is predicated on help from the North and Atlantic to fed off any warm ups and keep the boundary to our south.    Eventually uts and we go to rain after a lot of wintery preip.  Will be different in 6 hours but a pbp is a pbp.

My low here this morning was 11.8 and my low yesterday morning was 12.7.  I still have about 3" solid snowcover in my north-facing backyard.  In my south-facing frontyard patches of bare spots have started to appear, especially after yesterday's balmy high of 44.2.  I would estimate that 85-90% of the front yard still has at least one inch of cover.

Concerning the earlier post from @Itstrainingtime, regarding the use of the word "breezy" in the nws forecasts, while I don't know the precise value, it is the sustained wind, not the wind gusts that determines the use of "breezy".  I believe the threshold is sustained speeds of 20-25 mph.  When the sustained wind is forecast to exceed 30 mph the adjective changes to "windy".  The gust speeds and the frequencies of reaching these values are what is used to determine wind advisories and high wind warnings.  I think that frequent gusts over 40mph qualify for a wind advisory while frequent gusts over 50mph+ qualify for a high wind warning.  Please don't hold me to precise values for any of the wind speeds.  I'm pretty sure the values I mentioned are at least "close" to the correct figures.

Thank you! That's quite helpful. Here is the exact forecast for Wednesday in Maytown which would validate your post:

Wednesday

A slight chance of rain showers between 1pm and 4pm, then a slight chance of snow showers after 4pm. Partly sunny, with a high near 45. Breezy, with a west wind 15 to 24 mph, with gusts as high as 45 mph. Chance of precipitation is 20%.

We should end the month ~5 degrees BN.  In fact, my pen, notepad, and TI-84 Plus tell me we'll end January with a mean temp of 25.7 degrees.  This would tie 1895 and 2003 for 21st coldest January all-time.  Book it.

I did a little (emphasis on that) research over lunch, it appears as if January 2025 will be the first BN temp month at MU since November 2023 if I'm reading this correctly. 

https://www.atmos.millersville.edu/~wic/climo/t-anomaly.htm

The last month that MU was at least 5 degrees BN was April 2018. 

Edit: The cold Januarys of 1977 and 1994 really stand out on that graph. We all talk about 1994, for old guys like myself, 1977 will always be the benchmark. Over 11 degrees below normal for the month. The Chesapeake Bay was walkable shore to shore that winter.

First week of Feb shaping up quite chilly on the GFS after one day near or slightly an (talking highs).   GFS slowly pushes the boundary further and further south as the week wears on...in a very zonal flow.   How Chilly?  It is snowing in coastal NC on Thursday the  6th. 

-5 degrees out in Wyoming this morning.
I had 7° for the low this morning.

Currently 38 degrees. But the wind makes it seem chilly.

Plenty of clouds around today with our temperatures near normal (upper 30's) for late January. Tomorrow looks like the warmest day of the week with highs into the mid-40's. Some much-needed rain moves in by Friday morning which could briefly start as some freezing rain. The sun returns on Saturday with more rain by Sunday night.
