Sunday November 29 2020

Now we have some shape to the evolving pattern. Here is the Gulf Storm, the first of many (I expect this winter).  This one will have warm air, and bring in a marginal risk for severe storms to our region.  With the contrast of this energy and the cold air to follow, heavy rain will move through. This will mostly be in the morning, then a line with some thunder and severe risk in the afternoon.

A full moon will occur on Monday. I have shown this often coincides with overachieving storms. It will play a role with enhanced tides and some shoreline flooding on the Chesapeake Bay. See the wind highlights below.

Sunday Evening Weather

Storm Highlights

Heavy Rain

Most of the region will be within reach of 1 inch of rain during Monday.

The hourly timeline is below.

Monday Storm Risk

There will be heavy rain in the morning, then some lines of possible thunderstorms in the afternoon. With temps pushing the 60s and abrupt wind shifts with height (sheer), there could be some low level rotation.

The cold air aloft could also bring low level small hail with the afternoon activity. The Marginal Risk is small, but still worth paying attention to.

As heavy snow bands set up in the mountains, the first push of rain mixed with snow showers will pass through the northern half of the region.

More snow showers and flurries are possible into Tuesday afternoon.
