Area forecast discussion, Jun 29, 3:13 PM EDT, 26 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 313 PM EDT WED JUN 29 2016 .NEAR TERM [Through Tonight]... A weak trough axis remains situated across the region this afternoon with an associated front draped across the southern half of GA/AL/MS. This, coupled with an increase in deep layer moisture today (PWATS generally ranging from 1.9 to 2 inches area wide) and forcing from the seabreeze are yielding widely scattered showers and thunderstorms across the region at this hour. This activity is expected to gradually spread northward this afternoon and continue into the evening hours before tapering off. The lack of deep layer shear available today will make locally heavy rainfall a threat, with 1 to 2 inches of accumulation possible with the strongest storms. Little changes to the grids were warranted, as a large area of likely POPS were already highlighted for this afternoon. .SHORT TERM [Thursday Through Friday Night]... Weak shortwave will round the base of the large scale trough on Thursday. With plenty of moisture in place, this feature will help to enhance showers and thunderstorms across most of the forecast area on Thursday continuing into Friday. Expect an early start to the activity along the Panhandle coast Thursday morning, spreading inland through the day. Highest PoPs will be painted along the I-10 corridor. Temperatures should be cooler than the past several days, with many areas not getting out of the 80s. The upper trough will continue to impact the weather on Friday, with the best rain chances shifted slightly eastward along I-10. .LONG TERM [Saturday Through Wednesday]... The long term begins with the Eastern CONUS upper level trough retreating and being replaced by a building ridge. With a frontal boundary lifting back to the north, rain chances will be returning to a more typical seabreeze pattern. With a deep, moist airmass in place (PWAT near 2 inches), forcing from the seabreeze should initiate chance showers and thunderstorms across the area. Rain chances will be greatest during the afternoon hours, decreasing overnight with the loss of heating. Inland highs in the low to mid 90s, lows in the low to mid 70s. Coastal highs in the upper 80s, lows in the upper 70s. && .AVIATION [Through 18Z Thursday]... Scattered showers and thunderstorms continue across much of the region this afternoon, with all TAF sites expected to be affected at some point this afternoon. Gusty winds and reduced vsby, perhaps briefly down to IFR will be possbile under thunderstorms. Otherwise, VFR conditions expected with thunderstorms tapering off later this evening. Light patchy fog is not out of the question tonight, particularly in and around areas that receive rain this afternoon. && .MARINE... Generally light to moderate south to southwest winds are expected over the coastal waters through the weekend. && .FIRE WEATHER... No concerns. && .HYDROLOGY... Isolated to scattered thunderstorms are expected over the next several days, becoming more isolated towards late weekend and early next week. Isolated areas of up to 2 inches of rainfall will be possible over the coming days. No widespread flood concerns are anticipated. && .PRELIMINARY POINT TEMPS/POPS...
