Moisture-Laden Weather Pattern Finally Departs, Overall Improvement in the Weather Expected...

Good Tuesday morning to everyone across the Western Carolinas...after what turned out to be a wild and action-packed weather weekend, we can all take a deep breath of the next few days as the pattern is relaxing some.


We were dealing with a cutoff upper low that had deep tropical moisture to work with. That combined with terrain effects created the big flood event we had. As you look at the water vapor image this morning the biggest things to note are that the upper low has diminished greatly and the tropical moisture has been pushed almost entire off the East Coast...which is good news.

Surface Weather Pattern and Winds (Tues PM)

High pressure located across the Ohio Valley is pushing in drier air at the low levels of the atmosphere...Tuesday overall should be a pretty nice day weather-wise. We still have slim convection in our forecast since it is mid-June...but a lot of people will rejoice in the dry weather that is expected to occur today. High temps should respond by reaching into the 80's and some locations...







Surface Weather Pattern and Winds (Wed AM)

On Wednesday there may be a wrinkle in this pattern as high pressure moves into New England and weak low pressure will slowly move east from the Florida Panhandle. Computer guidance is somewhat aggressive in bringing clouds and maybe light moisture back toward the Southern Appalachians. We'll have to watch future model runs to see how that will impact the Wednesday forecast. Temps may struggle to reach the 70's dependent on extent of clouds...






The overall synoptic look through the current forecast cycle shows a Greenland Block setting up which allows a trough to generally be in place across the Eastern US. Depending on the trough placement, it could mean dry weather but if the trough axis is along or east of the Apps. However if tries to shift back to the west toward the Mississippi River, it could veer the upper level winds back into a position that brings moisture back into the Southeast...there are a few signs of that happening for the Father's Day Weekend...
