Strong winds are still prevalent with this push of chilly air. The low humidity also increases the fire danger, and we had a few wildfires erupt yesterday.
Lake Effect Snow bands are still crossing Central PA, and some flurries made an attempt to pass into our northern suburbs overnight. There could be a flake or two this morning, but the wind remains the main story.
This week will be active as two rain events pass just to our south, Tuesday night and Friday night.
This will mark warmer air attempting to move in and take a firmer hold around Thanksgiving. Then the bottom will fall out as an Arctic blast is expected to arrive in time for the start of December.
Mount Airy, MD had a gust to 61 mph.
The winds will remain strong in this transition zone between Low Pressure exiting Eastern Canada and High Pressure building our way form the Mid West.
Lake Effect Snow has narrowed to a few bands in Central PA and New York. The next weather system racing our way is just off the edge of the screen.
The fast moving pattern will send two mostly rain events our way from the Central US.
Light rain develops. This may start with some flakes or sleet pellets mixed in to our north.
The rain will end during the morning.
Light Rain is expected to arrive again in the afternoon.
Steady rain overnight should be moving away during the morning hours.

Big flip is expected to begin with a warm-up for the Thanksgiving holiday, then a surge of arctic air to the East Coast to start December.
A pocket of cool air with light rain. A larger storm in the Pacific Southwest, while Mild Air EXPANDS across the Central US and heads our way.
This wide view helps show how the warm-up expands to the Eastern US on Thanksgiving as the first impulse of cold air drops into the Western US.
The specifics are still not locked. I would plan for a warm weather pattern with some fluctuations. The contrast to cold in the west is a likely indication of strong to severe storms in the Central US across the boundary in between.
This is when the surge of arctic air is expected to push into the Eastern US as the Polar Vortex gets disrupted and may set up the pattern for next month to kick off winter.

I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. 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 during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I can also make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
