275 FXUS62 KKEY 181447 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1047 AM EDT Thu Jul 18 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1045 AM EDT Thu Jul 18 2024 This morning we had a spackling of showers and isolated thunderstorms across the region. The morning sounding showed a PWat of just over 2 inches. This was corroborated with MIMIC satellite derived Total Precipitable Water imagery. Speaking of satellite derived TPW, behind this plume of moisture is relatively drier air surging in from the east. Looking at visible satellite the cu definitely looks more shallow and tame compared to what went through our neck of the woods this morning. Otherwise, ridging remains in place that east to southeast winds will persist though we will enter a lull going into the afternoon and winds will slacken as a result. In addition, we will continue to flirt with near Heat Advisory conditions once again so keep the water handy and seek shade as often as possible. Made minor changes to the going forecast, specifically to PoPs. Given the aforementioned dry air moving in from the east, combined with radar and satellite trends, decided to nudge down PoPs for the remainder of the day. Our best chance for rain looks to have already occurred. Otherwise, no changes made to the going forecast. && .MARINE... Issued at 1045 AM EDT Thu Jul 18 2024 Atlantic ridging will remain across the Florida Peninsula through the forecast. This will result in gentle to moderate east to southeasterly breezes across Keys waters, peaking in the evening and night hours and lulling during the day. Winds are expected to trend upwards this weekend as the ridge lifts northward into North Florida and the southeastern United States. && .AVIATION... (15Z TAFS) Issued at 1045 AM EDT Thu Jul 18 2024 VFR conditions will prevail at the EYW and MTH terminals through the overnight hours. Surface winds will remain from the east to southeast near 10 knots. && .CLIMATE... On this date in Keys Weather History, the daily record warm low temperature of 87F was recorded. This is also tied for the warmest low temperature ever recorded for July for the Key West area. Temperatures records for Key West date back to 1872. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
