High pressure will slide east to the Mid-Atlantic States through this evening as upper level clouds will at times put the area under partly to mostly cloudy skies. This high pressure will remain anchored to the northwestern Gulf through Tuesday. As a result, northeast to east flow will remain over the forecast area keeping dew point readings below 50 degrees through Tuesday. This means dry air will be in place and humidity will remain low.
A trough of low pressure will develop over northeast Gulf of Mexico late today into Tuesday. This feature will give the surface flow a more northeast component Tuesday into Wednesday. Nice weather is expected to continue through Wednesday. Moisture will slowly increase over the coastal waters Tuesday and slowly increasing over the viewing area on Wednesday.
The next system will approach the forecast area late Thursday into Friday. This feature will create a winds out of the south and bring moisture north across South Mississippi on Thursday. However, instability will be limited Thursday afternoon through Friday morning, with only isolated thunderstorms possible across the north half of the area with the approaching frontal forcing. Elevated rain chances will be confined from Thursday afternoon through Friday noon. Severe weather is not anticipated with this system. Another dry and cool weekend is expected next weekend.
