Forecast for Sunday, September 9, 2012

Thunderstorms into this evening have the potential to create havoc in some areas with damaging wind gusts and isolated tornadoes. The Storm Prediction Center continues to forecast widespread damaging winds. Some of the strongest thunderstorms have the potential to produce destructive and significant wind gusts.   All of the thunderstorms may be capable of producing heavy rainfall, frequent lightning, and hail. See our Twitter Account, Facebook Account, and our previous blog post issued earlier today for more on the severe weather into this evening. All thunderstorms should clear the coast around or just after midnight. This is courtesy of a potent cold front moving east.

The driving force for this severe weather outbreak is a significant pattern change which will usher in significantly cooler temperatures than what we have been observing for daytime highs and nighttime lows and a relatively dry stretch of weather with no chances of t-storms. Highs in the mid and upper seventies will dominate Sunday, Monday, and Tuesday with high pressure in control. By Wednesday, temperatures will come up slightly and moderate a bit as the position of a strong high pressure system changes. Dew point temperatures will be in the very comfortable range Monday through Wednesday and in the comfortable range Thursday and Friday. There are no real forcing mechanisms out there this week and with dry air in place, we should see mostly sunny to sunny skies.

The positive side of this cold front is that it has bounced our tropical activity to our east. However, a moderate to high risk of rip currents continues through early in the week due to swells being produced by the combination of Leslie and Michael. We will be watching the newest tropical wave to emerge off of Africa.
