Area forecast discussion, Aug 9, 12:05 AM CDT, 1 hour 2 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 105 AM EDT Fri Aug 9 2024 ...New AVIATION... .UPDATE... Issued at 912 PM EDT Thu Aug 8 2024 No significant changes to the previous forecast appear necessary. Lingering isolated showers and thunderstorms across southwest Georgia should diminish in the next few hours. For early Friday morning, some thunderstorm activity could develop along the big bend coast in association with the land breeze and a weak surface boundary. && .NEAR TERM... (Through Friday) Issued at 315 PM EDT Thu Aug 8 2024 A few showers and thunderstorms are ongoing this afternoon as a weak shortwave moseys over the region. A few wind gusts in excess of 40 mph are possible within any thunderstorms this afternoon and into the evening. A strong to severe wind gust cannot be entirely ruled out, especially as storms approach the eastern Big Bend where RAP analysis shows DCAPE values over 1000 J/kg. Any activity this afternoon should wind down near or following sunset. Another hot day is in the offering again Friday with highs climbing into the middle to upper 90s. With temperatures a degree or two lower than today, heat indices should generally top out between 108 to 112 degrees Friday afternoon. A Heat Advisory will be issued at a later shift to avoid confusion with the ongoing Excessive Heat Warning for today (Thursday). That said, there is an outside chance, less than 20 percent, of one or two locations nearing or exceeding Excessive Heat Warning criteria, or a heat index in excess of 113 degrees, Friday afternoon. Much of the area is forecast to remain dry Friday afternoon as drier air aloft filters in from the north. However, a subtle shortwave embedded within the mean H5 flow may be enough to spark an isolated shower or storm. Some of the storms may be capable of producing damaging wind gusts as model soundings from around the area show an inverted-v profile. && .SHORT TERM... (Friday night through Saturday night) Issued at 315 PM EDT Thu Aug 8 2024 A deep upper level low is expected to push a weak frontal system into our region, late Friday night into Saturday. Guidance currently favors storm development along the sea breeze and east of the weak frontal, where moisture and weak lifting mechanism are greatest. Damaging wind gusts, perhaps strong to severe at times with the drier air influence, and heavy rain look to be the primary hazards. In addition to storms, another hot day is on tap. Highs are expected to be in the mid to upper 90s for much the region, with the Big Bend being a few degrees lower and in the low to mid 90s. Heat Index values of 105 to 112 are expected, with a few localized areas potentially meeting excessive heat warning. Will need to see how the cloud cover, precip looks, and temperatures trend before issuing any product this far out. && .LONG TERM... (Sunday through Wednesday) Issued at 315 PM EDT Thu Aug 8 2024 Ensemble and cluster analysis shows the upper level trough that absorbed Debby skirting along the northern Great Lakes Sunday into Monday. Behind it upper level ridging builds to the west, leaving us with more zonal flow this period. Then, as we head into the work week ensembles keep the trough, albeit not as deep, of the northeast. Upper level ridging from the west builds and then dominates much of the region as it expands into the Plains and Upper Midwest. The influence form the ridge is expected to expand into our region, leaving us with northwest flow for the start of the work week. Will need to keep an eye on that as it could raise MCS concerns, but it's too early to pin point anything yet. We can expect to see typical summer time weather with daily shots of showers and thunderstorms and high temperatures in the low to mid 90s. && .AVIATION... (06Z TAFS) Issued at 104 AM EDT Fri Aug 9 2024 VFR conditions are expected through the period. A few storms will be possible across the FL Big Bend and far south GA this afternoon. && .MARINE... Issued at 315 PM EDT Thu Aug 8 2024 Moderate winds are being observed by surrounding buoys, supporting gradually improving conditions. Seas will generally remain around 2-3 feet through the end of the work week, before dropping to around 2 feet by the weekend as winds slowly relax. Winds are expected to continue to decrease through the beginning of the next work week to around 5 knots or less, which will lead to tranquil boating conditions. There will be daily chances showers and thunderstorms, particularly during the overnight and morning hours. && .FIRE WEATHER... Issued at 315 PM EDT Thu Aug 8 2024 Mostly dry conditions are expected through Friday. There is an outside chance of a few showers and storms across the FL Big Bend again on Friday. While rain chances will be low, the only fire weather concerns will be high dispersions along with hot temperatures with heat indices pushing 105 to 110 degrees. && .HYDROLOGY... Issued at 315 PM EDT Thu Aug 8 2024 Rivers remain elevated with the Aucilla River at Lamont, Steinhatchee at US-19, and Valdosta at Skipper Bridge remaining in minor flood stage for a few days. The Suwannee River is expected to have some rises and may reach minor flood stage over the weekend or early next week. Will need to keep an eye on that to see how the water levels trend. Outside of that, mostly dry weather prevails through the work week. Chances for showers and storms improve over the weekend. Outside of that, the other area of hydrologic concern is Madison County where more than 12 inches of rain from Hurricane Debby. A Flood Warning was issued for Madison County until at least Friday afternoon. Madison County Emergency Management reported rising water levels in the southeastern portion of the county, just south of Interstate 10 east of County Road 360, especially in the vicinity of I-10 and Exit 258. Water levels are likely to continue to rise and gradually spread to areas south and east across the county as localized runoff continues. Numerous roads are flooded, along with a campground near Exit 258 being significantly impacted. Some roads are already or will soon become impassable. For those that may be traveling through Madison County, be mindful of road conditions. If you see a flooded road turn around, don't drown! && .SPOTTER INFORMATION STATEMENT...
