604 FXUS62 KTAE 270910 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 410 AM EST Fri Feb 27 2015 .Near Term [Through Today]...
-- Changed Discussion --
A drier airmass will be advecting into the area today with a large surface ridge centered over the plains bringing northerly surface flow into the region. Meanwhile, some upper level moisture will continue streaming across the area with some high clouds. Afternoon high temperatures are expected to range from the upper 50s across the northwest to the low to mid 60s across the southeast big bend. .Short Term [Tonight Through Sunday]... Strong surface high pressure centered over the Midwest tonight will slide east to the Ohio Valley and into New England over the weekend. As it does, a wedge of high pressure will build down the lee of the Appalachians into our region with increasing low level northeasterly flow. This will also bring increasing cloudiness resulting in lower afternoon temps especially northern zones Saturday. Also we could see scattered showers mainly southeast zones on Saturday as isentropic lift sets up with winds above the boundary layer veering to the southeast. As the surface high weakens somewhat on Sunday along with flow becoming nearly zonal in the mid/upper levels, look for temps to warm to near seasonal levels. .Long Term [Sunday Night Through Friday]... The warming trend will continue at least through mid-week as low level flow becomes onshore as the surface high moves off the mid-Atlantic and northeast U.S. coast. The increasing low level moisture and above seasonal temps will keep low end PoPs in the forecast Monday and Tuesday. Then an amplifying upper trough over the nation`s midsection with a leading developing cold front will bring increasing chances for rain and thunderstorms to the region Wednesday and Thursday.

Strong high pressure moving eastward through the midwestern states will keep the gradient tight and winds elevated through much of the weekend. Expect to see conditions reach advisory levels tonight and remain at these levels through early Sunday. Conditions should improve by Sunday afternoon continuing into early next week as the area of high pressure weakens.

Most of the area saw 1-2 inches of rain Wednesday which has led to a rise on area rivers. Several rivers will reach action or bank full stage. The Kinchafoonee Creek at Dawson and the Withloacoochee River at Valdosta will reach minor flood stage on Saturday.
