Morning Report
This is the weekend we get the reboot of winter. I have been mentioning the Polar Vortex ‘Disruption’ because that core circulation will be dislodged and pushed south. It will NOT be on top of us, but it will be tracking through northern New England. After seeing snow mixed in with showers and then a few morning deep freezes, it will be hard to doubt.
Today we have a disturbance that will bring in the initial colder air. Rain showers will develop on gusty winds. While the high temp will be near 50ºF, that will be early afternoon, then drop along with some snow or graupel mixed showers.
The mountains will be getting accumulating snow with as much as 6 inches in parts of western Maryland.
The core of the cold air for metro and coastal areas will be late Sunday into Monday. Most of next week will be chilly, but a brief warm up will come with rain by Thursday. Let’s take a look.

*Disclaimer due to frequent questions:
I am aware there are some spelling and grammar typos. I have made a few public statements over the years, but if you are new here you may have missed it:
I have dyslexia, and found out at my second year at Cornell. I didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region.
I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse.
All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline.
I accept this and perhaps proves what you read is really from me…
It’s part of my charm.
