Area forecast discussion, Jul 10, 1:56 PM CDT, 3 hours 17 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 256 PM EDT Mon Jul 10 2017 .NEAR TERM [Through Tonight]... Scattered to numerous showers and thunderstorms will continue through the afternoon hours and diminish after sunset. Modifying the 12z KTAE sounding for an afternoon T/Td of 91/74 yields SBCAPE values around 4000 j/kg. Given the high instability and observed 700- 500 mb lapse rates over 6C/km, there could be a couple of strong to locally severe storms this afternoon, which is typical of summer. The RAP also supports this thinking with WMSI values forecast near 80 this afternoon. Overnight lows will generally be in the low to mid 70s. .SHORT TERM [Tuesday Through Wednesday Night]... Surface and upper level ridging will continue to expand westward from the western Atlantic. However, models don't show any significant drying across our region until Wednesday afternoon and then mainly just our eastern zones. Look for another typical summertime day Tuesday with PoPs 50% most inland areas and highs in the lower 90s. For Wednesday, PoPs will be trimmed back to 30% for most of our GA zones and the SE Big Bend with 40-50% elsewhere. Highs Wednesday should reach the lower to mid 90s away the coastal areas. .LONG TERM [Thursday Through Monday]... As ridging builds further west, we will see additional drying and warmer temperatures across the area through the remainder of the work week. Chances for afternoon and early evening showers and thunderstorms will fall to 20-30% for Thursday and around 30% on Friday. Rain chances increase to near seasonal levels over the weekend into Monday as the ridge breaks down and a trough deepens along the Atlantic seaboard. This will send a surface front our way along with increasing deep layer moisture. Additionally, both the EURO and GFS show tropical moisture from the remnant of Tropical Depression #4 moving into the eastern Gulf and lifting northward over the weekend. The EURO is more bullish and shows possible redevelopment of this feature with a closed surface low approaching SE LA on Sunday. This will be monitored closely. Highs will remain in the low to mid 90s and lows will be mostly in the mid 70s. && .AVIATION [Through 18Z Tuesday]... Scattered to numerous TSRA will continue through the afternoon hours and diminish after sunset. Outside of convection, VFR conditions are expected to prevail. && .MARINE... High pressure will dominate through the period with light winds and low seas. There will be chances for showers and thunderstorms throughout the period. && .FIRE WEATHER... No concerns. && .HYDROLOGY... A wet seabreeze pattern will remain in place a few more days, however due to the scattered nature of these storms, no widespread heavy rainfall is anticipated from these storms. Any flooding impacts will be isolated to areas of localized heavy rainfall. Our rivers will remain below flood stage. && .PRELIMINARY POINT TEMPS/POPS...
