Outlooks:

What- Rainy/Mild to Colder/Snowy/Windy

6:51am Radar 12/10/23

Current Advisories;

Winter Storm Warnings out for the high Wv elevations in the pink shade and Winter Weather Advisories out in the purple shade. These likely will expand in to parts of the southern Pa high elevations and some of the Winter Weather Advisories potentially will creep in to Warning criteria.

My thoughts from yesterday really haven’t changed much. A general 4-8″ with localized higher pops across the high Wv elevations 3500’+ and 3-6″ with localized higher pops 2500-3500′. 2000-2500 2-4″ .

A look at the 0z ECMWF for the event

Snowfall off the models

Short Range Canadian RDPS above. The Canadian RGEM is better than the horrid US Nam for precip.

This is mainly a Sunday PM to Monday AM event. Expect road conditions across the high ground to deteriorate rapidly. If you have traveling across the high ground to do and you can work it in this morning to afternoon hours, that’s best.

The morning temps starting off in the 40s and lows 50s

and by evening those are crashing back to and below freezing. Modeled 7pm temps

modeled midnight

modeled 6am Monday

Temps won’t move a lot Monday as some upslope snows continue in the morning hours across the high ground. This will be accompanied by strong winds blowing the snow around. Initially a wet snow that will transition to a bit more powder as time goes on overnight.

Yesterday I referred to a similar rain to snow setup on Dec 7, 2011 that ended with these type of amounts. Similar numbers could be expected with this. Refer to yesterday’s post by clicking back a day at the bottom of the post

Nws advisories and snowfall maps can be viewed in the drop down menu under snowfall info per Weather Forecast Office.
