Thursday Evening Forecast Discussion – 6 p.m.
June 14, 2012 Leave a comment
A very unstable airmass has developed across Central Alabama this evening ahead of a front approaching from the east over northern Georgia. Behind the front cooler and drier air was filtering in from the northeast with upper 70s and lower 80s temperatures and dewpoints now in the lower 60s across northern Georgia. The front was nearing our far northeast counties and is expected to traverse across the eastern portions of the state during the evening hours. As it does so scattered showers and storms will continue to develop and generally increase in coverage. Any storm that does develop will be capable of producing an isolated damaging wind gust up to 60 mph and very heavy rainfall that could produce some localized flooding due to the very slow moving nature of the storms. Showers and storms will continue to develop westward through the evening finally decreasing in strength with the loss of daytime heating.
As the front continues to move westward across the state and easterly flow sets up on Friday a few scattered showers and storms will continue to be possible ahead of the front for our western counties and we will have to monitor the mesoscale conditions just like today for the possibility of more widespread shower and storm development.
Fairly benign conditions look to return to the Southeast for the long term period as an easterly flow remains over the weekend and shifting to the southeast by early next week. Temperatures look to be a bit cooler with the easterly flow with generally upper 80s to perhaps 90 degrees through the weekend and warming up once again by Tuesday and Wednesday of next week. With high pressure aloft and at the surface in control, the chance of any widespread thunderstorm development looking fairly limited.
