Area forecast discussion, Jul 3, 1:50 PM CDT, 3 hours 2 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 250 PM EDT Tue Jul 3 2018 .NEAR TERM [Through Tonight]... Scattered showers and thunderstorms will continue to develop mainly along and west of the river this afternoon and move to the west. Then, we should see a broken line of showers and thunderstorms associated with the east coast sea breeze arrive late this afternoon over our easternmost zones. This convection is forecast by a few of the hi-res models to continue to move westward across the remainder of the CWA through the evening and possibly into the early morning hours. Pops will be in the 40-50% range until 06z. Lows will be in the lower 70s. .SHORT TERM [Wednesday Through Thursday Night]... A tropical upper tropospheric trough will move westward into the FL Peninsula on Wednesday afternoon and evening, with a surge of deep layer moisture just west of this feature moving into our area during these times. PW values around or over 2.0" will combine with sea breeze forcing and ample instability (SBCAPE 1500-2500 J/kg) to result in high coverage of showers and thunderstorms. Highest chances will be across the FL Big Bend and parts of SW Georgia, as the Atlantic sea breeze is projected to move into these areas during the late afternoon and early evening and enhance potential for showers/thunderstorms. However, during Wednesday evening after 00Z, chances of showers and storms should be much lower as the atmosphere is projected to stabilize behind the initial wave of showers/thunderstorms. Drier conditions are expected on Thursday as drier mid-level air moves over our area from the east behind the aforementioned upper trough. Still, some scattered showers and thunderstorms are possible during peak heating hours (afternoon and early evening) as the sea breeze moves inland. Highs on both Wednesday and Thursday will range from the upper 80s to lower 90s across our area. .LONG TERM [Friday Through Tuesday]... Another upper level low is expected to move westward across our area on Friday morning and afternoon, with seasonably moist conditions persisting throughout the day on Friday. This will result in decent coverage of scattered showers and thunderstorms across our area, especially during the afternoon and early evening as sea breeze forcing and instability are maximized. Even higher chances of showers and thunderstorms are expected this weekend as a weak surface trough/front drifts southward toward northern portions of our area. Ample deep layer moisture will persist from the weekend through early next week as well. As a result, showers and thunderstorms will be likely across our area on Saturday and Sunday, with high-end chances continuing through Monday and Tuesday. Highs will range from the upper 80s to lower 90s across our area for most of this period, but possibly remain in the mid-upper 80s on Sunday under more widespread cloud cover and showers/storms. && .AVIATION [Through 18Z Wednesday]... Scattered showers and thunderstorms associated with the east coast sea breeze will spread from east to west later this afternoon and evening possibly impacting all terminals. Brief periods of gusty winds along with MVFR vsbys and cigs can be expected with the stronger storms. && .MARINE... Generally light winds around 10 knots or less and seas of 2 feet or less will continue through the next several days, along with persistent chances of showers and thunderstorms. && .FIRE WEATHER... Hazardous fire weather conditions are not expected through the remainder of the week as RHs will remain above critical levels. An exception will be Wednesday afternoon, where high dispersions will be likely in the Florida Panhandle, generally west of the Apalachicola River. Chances for wetting rains will increase again on Wednesday, with chances persisting into the weekend. && .HYDROLOGY... Rivers and streams are likely to remain below flood stage through the next few days; heavier rain from scattered showers and thunderstorms is generally expected to be short-lived. However, a few rivers/streams could continue to reach action stage at times, and minor flooding cannot be ruled out in isolated areas that receive more persistent showers and thunderstorms. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
