NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Sep 3, 1:27 PM CST, 2 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 327 PM EDT THU SEP 3 2015 .Near Term [Through Tonight]... Afternoon showers and thunderstorms may linger into the early evening hours. These storms will be isolated. Overnight, rain chances will dwindle. Lows will be in the low to mid 70s. .Short Term [Friday Through Saturday Night]... A broad, east-west oriented 500 mb trough will develop across the western Atlantic and Southeast. At the surface, a weak "backdoor" cold front will translate southward Saturday and Sunday as a wedge of high pressure builds southward along the Piedmont. With little Q-G forcing expected on Friday, the driving force behind any shower and thunderstorm development will be the sea breeze front. The FL Big Bend front will be slow to move inland due to opposing 1000-700 mb winds, and the highest PoP will be around 40% across the FL Big Bend and north FL. Elsewhere the PoP will be 30%. PoPs will increase into the 50-60% range this weekend with the arriving cold front. Highs will be above average Friday, in the mid 90s, then a little "cooler" Saturday, in the lower 90s. Lows will remain in the 70s. .Long Term [Sunday Through Thursday]... The aforementioned 500 mb trough will become cut off from the mid latitude westerlies, then gradually become oriented north-south as it translates slowly to the west along the Gulf Coast. At the surface, the aforementioned cold front will stall across the northern Gulf of Mexico and north FL into early next week as it gradually dissipates. With the mean east-northeast flow from 1000- 700 mb through Monday, the highest PoPs will come late in the afternoon or evening as convection associated with the FL/GA east coast sea breeze front arrives. The flow will become southerly by mid week, resulting in a more normal progression of the FL Big Bend and Panhandle sea breezes. PoPs in FL will be slightly above climo, generally around 40% each day. Elsewhere, where the boundary layer is a little drier, PoPs will be around 30%. Temperatures will be near climo, around 90 in the day and in the 70s at night. && .Aviation... [Through 18Z Friday] VFR will prevail at all terminals. There is a chance for thunderstorms this afternoon and early evening, mainly along the seabreeze boundary. However, showers and thunderstorms will be isolated in coverage and therefore were not put into the TAFs. Winds will be light and northwesterly. && .Marine... With a weak pressure gradient across much of the Southeast, winds will be relatively light from the west or northwest through Friday. Winds will gradually transition to the east or northeast this weekend as a weak cold front passes slowly through the region from north to south. && .Fire Weather... Red flag conditions are not expected for the next several days. && .Hydrology... Area rivers remained below their local action stages this afternoon, and this is likely to continue for the next several days in the absence of organized heavy rain. && .Preliminary Point Temps/PoPs...
