Area forecast discussion, Jul 5, 6:05 PM CDT, 7 hours 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 705 PM EDT Thu Jul 5 2012 .MESOSCALE DISCUSSION... During Thurs aftn into early eve, shallow Gulf seabreeze pushed inland sparking isold strong convection. Looking N/NE, sct strong to severe convection moved SSW from Cntrl GA into NRN tier of our GA counties and about to approach SE AL. Looking further upstream, MCV enhanced by outflow boundary was focal point for strong to severe storms across TN. Radar shows continued WSW movement and satellite extrapolation shows that a few of these storms may hold together and make it into Nrn tier GA counties soon after midnight and will be closely monitored. .SYNOPSIS... The large scale longwave pattern continues with ridge dominating most of Conus with 594dm high centered over MO/KS. Satellite shows shortwave riding down front of ridge into AL aiding afternoon convection over SRN GA. Trough was noted just off Atlc Coast with axis extending WSW to Carolina Coast and into Ern most Gulf of Mex. This places local area in between both systems with a ENE steering flow around SE portion of high allowing Nrn storms to shift swwd. For Fri into Sat, GFS/NAM and ECMWF seems to confirm that the trough over the Gulf Coast will indeed breakdown a bit as ridge re-exerts itself into the area. At same time, low level ridge builds in from Wrn Atlc into FL Peninsula. This puts most of FL Panhandle Coast back under a light S/SW 1000-700mb flow or a type 4 Sea Breeze Regime thru Sat. Model soundings show that PWs will remain between 1.8 and 2 inches thru Fri eve then drop to around 1.5 inches during Sat so under light steering flow, locally heavy rain possible. Expect isolated offshore convection in the morning with healthy convection just inland from the coast in the afternoon especially on Friday. However, weak shear and a lack of a strong focusing mechanism should keep the severe threat limited and less organized than recent days. .NEAR TERM /Through Tonight/... Above shortwave may aid further development of storms after sundown. PWs remain around 2 inches with wet microburst potential above average. So strong to at least isold severe good bet at least for Nrn counties especially SE AL/SW GA. With an eye to storms moving into our Nrn tier counties at 700 pm EDT, will up POPs especially across nrn tier GA counties 50-0% NW-SE POP gradient 00z-06z, then 30-0% NW-SE gradient 06z-12z. Min temps will be in the lower to mid 70s. && .AVIATION... Scattered thunderstorms associated with a stationary trof over south central Georgia will produce gusty winds and lowered VIS. Around 4z an organized cluster of storms that is currently over Tenn. will move into our area and could effect DHN and ABY. Some patchy fog is possible in the pre-dawn hours at VLD and ABY. Tomorrow CIGS and VIS will be VFR at all terminals, with the only restrictions occurring in scattered late afternoon thunderstorms. && .MARINE... Typical summertime conditions will prevail over the coastal waters through the weekend. Seas will remain 1 to 2 feet or lower and winds will remain light. The only concern is thunderstorm activity. With typical sea/land breeze effect we expect that some scattered to isolated thunderstorms will be generated over the waters in the pre-dawn hours on Fri and Sat. These will typically dissipate by mid morning. && .TAE WATCHES/WARNINGS/ADVISORIES... FL...NONE. GA...NONE. AL...NONE. GM...NONE. && BLOCK/DVD/WALSH
