An Ugly Few Days Ahead…

As the title of this forecast discussion suggests, the next three days do not feature particularly pleasant weather.  Things look a little better by the latter part of the weekend, but until then it’s going to be gloomy and wet.

A stalled frontal boundary remains to our north right now.  High pressure is situated off the South Carolina coast, providing the region with warm, humid air from the south.  The High Country is right in the middle of these two features, meaning we are in an area of very unstable atmospheric conditions.  As a result, widespread showers and thunderstorms will commence this afternoon.  While these storms won’t be terribly severe in terms of wind or hail, very heavy rain is expected.  Precipitable water values are above an inch and a half already, with moister air on the way.  That’s a lot.

The front will wash out tonight, but another one is going to replace it almost immediately.  In other words, Thursday and Friday will feature the same setup and conditions as today.  As I mentioned, heavy rainfall is expected over the next few days.  Localized flash flood warnings more than likely will be issued so make sure to pay attention to the weather.

High pressure will move back into the region by the second half of the weekend.  It will remain hot, but things should dry out a bit for the first half of next week.
