Area Forecast Discussion National Weather Service Tallahassee FL 626 PM EDT Sun Jul 12 2020 .AVIATION... [Through 00Z Tuesday] VFR through the period with westerly winds AOB 10 kts, with the following exceptions 1) tonight - brief TSRA are likely at DHN through 03Z 2) Monday - brief afternoon/evening TSRA at TLH w/ lower confidence at ECP and VLD, where PROB30's are in effect. && .PREV DISCUSSION [323 PM EDT]... .NEAR TERM [Tonight Through Monday]... The main concerns are the potential for severe weather this evening and a renewed chance of strong thunderstorms on Monday. Southeastward propagating MCS across central Alabama has a history of damaging thunderstorm wind gusts. A narrow axis of instability has developed ahead of this feature, which will aid in maintaining it further southward. Expect the potential for severe weather to diminish shortly after sunset, and with an arrival time of 5-8 PM CDT, this would put our southeast Alabama counties at the greatest risk. Some damaging wind gusts are possible across this area, and more isolated across the western FL Panhandle. Once this system clears the area, patchy fog is possible late tonight. On Monday, isolated damaging wind gusts are possible during the afternoon and evening associated with thunderstorms near the I-10 corridor. .SHORT TERM [Monday Night Through Tuesday Night]... Slightly drier air will work into northern sections on Tuesday with deep moisture remaining over our FL counties. Lingering boundaries from Monday's convection, along with some Gulf seabreeze, will be the primary triggers for afternoon storms. A few strong storms are possible along with locally heavy rain. .LONG TERM [Wednesday Through Sunday]... Upper ridge will build to our north over the TN Valley through the week with an extended period of deep easterly flow expected. PWAT values expected to be around two inches throughout the period which will create a favorable environment for both Atlantic and Gulf seabreeze convection each afternoon and evening. Hot temperatures will continue especially on Wed/Thu when advisory level heat index values are likely at many inland locations. .MARINE... Thunderstorms could produce gusty winds over Panhandle waters this evening otherwise winds and seas will be relatively light through the week as a typical summertime pattern sets up. .FIRE WEATHER... No hazardous fire weather conditions are expected over the next few days. .HYDROLOGY... There will be localized areas of heavy rain through the next week as mainly afternoon thunderstorms develop. Widespread heavy rainfall and significant hydrologic impacts are not anticipated however. .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur (while following all local, state, and CDC guidelines) by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
