Weather Disscusion

We will be entering a very quiet weather pattern for the next several days over the eastern 2/3rds of the country. But first we have a little snow to get through:

Tonight-Sunday:
-A upper level low will be affecting the lower Great Lakes and Appellations. It will produce some instability showers, especially during Sunday afternoon. Maybe even some thunder over the Appellations. Some of the showers will fall in the form of snow, especially high up in the Appellations and areas in northern OH/PA. Some light accumulations are possible but there will be no problems on the roadways. Some light snow showers are possible even in northern New England especially tonight.
-Any way you cut it the eastern half of the country will be 10-20 degrees below normal Sunday and maybe even Monday. Areas that clear out could see frosts and freezes even into the south. There are freeze watches up for Sunday night in central Alabama.
-High pressure and above normal temperatures will dominate the west.

Monday-Wednesday:
-On Monday the east will remain well below normal in the east. Instability rain and snow showers will continue to fall in the Appellations. Snow could even fall in north Georgia/western South Carolina.
-A weak system will affect the Northwest. Some mountain snows and light rain elsewhere but it will be a very quick, weak hitting area of low pressure.
-The middle of the country and the Rocky Mountains will be high and dry and will start warming in the middle of the country and stay warm in the Rockies on Monday.
-The east will be completely dominated by high pressure on Tuesday and Wednesday. It will remain cool from the Apps points east but temps will slowly begin moderating under mostly sunny skies. One possible blemish will be a low pressure forming off the SE coast and will move NE. It could throw some precip back at the Carolinas on Tuesday.
-The west will cool off as a trough swings through. The chill will be short lived and only last 1-2 days.
-The Plane states will be near normal Tuesday and Wednesday and will remain dry.

Thursday-???(hype):
-As the western trough moves east and picks up a little bit of Gulf moisture it will cause the formation of a low pressure over the Texas Panhandle late Wednesday. This weak system will move NE spreading some rain/thunder from the southern Planes to the Appellations. It will fizzle some when it hits the Apps. This system will bring little to no severe weather.
-Through the next 10-14 days the pattern will remain more zonal than anything else which will preclude extended periods of ab-normal temperatures and keep the chances of a major spring storm low.
