High pressure setting up shop along the Southeast Coast and building ridge across the eastern third of the country will result in the major warm up we have been advertising. All of this is well in advance of a vigorous upper level trough now sitting over the Southwest that is set to bring the high threat of severe weather and tornadoes to the central Plains Saturday afternoon into Saturday night and still some threat of severe weather from the western Great Lakes to the Texas coast Sunday into Sunday night. This trough will be lifting out to the northeast as it runs into the ridge during the early and middle part of next week and will not be bringing us any severe weather, but it will deliver a front that brings a cool down Tuesday night and Wednesday.
So, as it shapes up for Saturday, we are looking at nice weather with temperatures rising into the low 70s (though cooler near the water) with sunshine eventually giving way to late afternoon clouds as a warm front approaches from the south and west.
The warm front and its moisture will result in a couple of showers and perhaps a thunderstorm across the area Saturday night and perhaps into Sunday morning. The highest chance to get wet will be across the northern half of the viewing area. Then the front should lift away to the north and northeast allowing dry, warm weather and the return of sunshine Sunday with a southwest breeze. Dewpoints will be in the 20s and 30s Saturday, but will rise into the 50s Sunday afternoon for a different feel to the warm.
