Today: Mostly cloudy. A slight chance of showers and thunderstorms in the morning, then showers and thunderstorms likely in the afternoon. Highs in the lower 90s. Southeast winds 5 to 10 mph. Chance of rain 70 %.
Tonight: Mostly cloudy. A chance of showers and thunderstorms in the evening, then a slight chance of showers and thunderstorms after midnight. Lows in the mid 70s. South winds 5 mph. Chance of rain 50 %.
Scattered to numerous showers and thunderstorms are expected today across the area with the best chances across the western locations. Gusty wind and lightening will be the primary threats. Locally heavy rainfall amounts over 2 inches are possible due to the slow storm motion. Due to recent heavy rainfall over portions of the area localized flooding is possible.
Today's Pollen Level: 2.2 Low( out of 12): Predominate Pollen, grass.
Area forecast details: Synopsis...weak upper high is presently over the forecast area part of the narrow ridge which extends from north Mexico to a larger high over the Atlantic. South of this ridge mid-level lows are located over the southwest Gulf of Mexico associated with Alex and just northeast of the Bahamas with TUTT feature. TUTT has moved little over the last 24 hours and as a result drier air northwest of the low has remained well southeast of the area. Slow-moving front is presently located along the spine of the Appalachians. Multi- layered cloudiness blankets the area with temperatures generally in the middle 70s. Some middle- level vorticity and isentropic lift is producing mostly light rain showers over the Suwannee Valley and points south and west.
Deep layer moisture and instability will lead to scattered to numerous showers and thunderstorms again today. Limiting factor to storm initiation will be thick cloud cover and weak middle- level ridge. However precipitation will be ongoing and should become more widespread through the day with thunderstorms eventually developing within the showers. Have leaned toward the cooler NAM maximum temperature guidance today due to clouds and precipitation but day shift may need to make further adjustments downward if clouds remain thick.
As cold front sags south on Thursday into increasingly moist atmosphere precipitation chances will further increase across the area. Locally heavy rainfall is possible particularly during the afternoon and evening. Maximum temperatures will be held down with values remaining mostly in the middle to upper 80s.
As the cold front sinks farther south on Friday probability of precipitation will be on the decline especially across south Georgia. Thicknesses will drop and northeast flow will bridge the front keeping maximum temperatures in the middle to upper 80s. Minimum temperatures will drop into the lower 70s away from Atlantic coast where onshore flow will keep readings in the middle to upper 70s.
