Welcome to the last day of November! It’s a nasty one out there as the month ends, with a stout storm system crossing the Mid-Atlantic. Around 2 AM this morning steady rain began falling, and it’s going to keep rolling through the first half of the day. As the low continues off to the northeast this afternoon, a dry slot will start to build behind this morning’s shield of rainfall, giving us a break, if not an end to the rainfall for the day altogether. Once all is said and done, this brief burst of rain will still be enough to give us 1.25-1.75” of accumulation. Flooding issues, if any, will be minimal given the progressive nature of this storm. It will remain breezy throughout as well, from today through the overnight.
Heading into Tuesday, a lot of cold air will be getting pulled down from the north, and a transition from rain to snow will occur over the far western mountains. Upslope flow created by strong northwest winds from this deepening low will make for a favorable environment for steady snow Tuesday and Tuesday night. I see two things working against this setup however: dry air that will be filling in and how warm it currently is out there. That being said, accumulations of 3-6”, locally up to 8”, is likely over far western Garrett County. From there, snow totals drop off substantially, to only a trace likely into Cumberland. The rest of the viewing area will be cloudy, breezy, but free of any sort of winter weather.
After what is sure to be an active two days, we finally quiet down the rest of the week. High pressure will give us some sunshine Wednesday and Thursday with fairly seasonable temperatures. On Friday, clouds will begin to return as the overall pattern sets us up for yet another closed off low into the weekend. This one may be a little closer to the coastline, but otherwise the finer details on storm strength and potential precipitation are still very uncertain. Given the typical way these systems set up, it’s likely we’ll have scattered rain showers across the eastern valleys, with scattered snow showers over the mountains where colder air lingers.
Stay dry out there and have a great Monday!
