A cold front is expected to stall over or close to the region by the middle of next week. Near term until 6 am Saturday morning Convection has really struggled to get going across the local area though we are flanked by scattered to numerous showers and tstms to the west and south, mainly oriented along the surface trough. Convection is expected to gradually move into our inland southeast ga zones late this afternoon. The sea breeze is also beginning to develop, though we may be beyond the time of greatest instability by the time it begins advancing inland. Only weak upper vorticity energy exists across southeast ga and it's progged by the NAM to shift northwest through mid evening. We show the greatest pops across inland areas through early this evening, diminishing below 15% by late this evening. Isolated convection will be possible over the coastal waters later tonight as a weak land breeze develops. Short term 6 am Saturday morning through Monday Overall, the pattern looks as though it will favor decreasing thunderstorm coverage through this period with continued warm temperatures. Upper ridging will prevail this weekend, then weaken through Monday as longwave troughing spreads into the eastern half of the conus. At the surface, the pattern will virtually remain the same through the period featuring an inland trough and subtropical high pressure to the east. Model precip fields almost all show less convective coverage each day, with the lowest perhaps on Sunday. Still with temperatures reaching the mid to upper 90s each day, it will be hard to not at least get isolated coverage each afternoon. So the forecast contains 20-30 percent chances each day. While there is no significant organized severe threat, it is interesting to note that model soundings each day show dcape values in the 1000-1300 j kg range. So whatever storms do develop could have an enhanced ability to produce strong wind gusts. Can't rule out a strong to marginally severe storm each day. Heat index values are expected to top out around 105 each day, highest along the coast, so it does not appear likely that heat advisories will be needed. Long term Monday night through Friday A substantial pattern change for the southeast states with the |
summer ridge giving way to broad mid upper level troughing. A slow moving cold front is forecast to drift from the mountains on Tuesday, over eastern ga and the coastal carolinas during mid week. Confidence continues to slowly increase for numerous showers and tstms across the forecast area during the middle of next week. The increase in clouds and precip will result in lower temps that average near or slightly below climo after Tuesday. Aviation 19z Friday through Wednesday Vfr conditions will prevail into at least early afternoon. Thereafter we expect scattered shra tsra at or near the terminals, with the highest probabilities of flight restrictions to occur roughly between 20z and 23z. Impacts appear high enough at ksav to include a tempo group for MVFR conditions, but just vcts and CB clouds at kchs. Extended aviation outlook: brief flight restrictions and gusty shifting winds could occur within near thunderstorms, especially during the afternoon evening hours. The chance for thunderstorms associated flight restrictions could be greatest starting Tuesday as a cold front approaches the region. Marine Moderate southwest flow will continue through tonight with seas 2-4 ft. South to southwest flow will prevail through most of the period. Wind speeds this weekend and into Monday will be enhanced at times, surging into the 15-20 knot range. As we get closer to the middle of next week speeds should be topping out in the 10-15 knot range. Seas should be 2-3 feet through most of the period, though up to 4 feet around 20 nm and beyond this weekend and early next week with the stronger periods of winds. Overall, conditions are expected to remain below small craft advisory thresholds. Chs watches warnings advisories Ga... None. Sc... None. Marine... None. Near term... Jrl short term...

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
