688 FXUS62 KKEY 290825 AFDKEY Area Forecast Discussion National Weather Service Key West FL 425 AM EDT Mon Apr 29 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 425 AM EDT Mon Apr 29 2024 Feels like a bit of deja vu across the Florida Keys as another breezy and muggy night comes to an end. Similar to last night, there`s been just enough low level moisture to support a few shallow showers crossing over the island chain. Currently, fresh to occasionally strong easterly breezes continue to drag brief bouts of precipitation across portions of the Lower Keys. As a result, temperatures across the island chain range in the lower to mid 70s with near steady dewpoints in the mid 60s. We`ll finally see some relief from breezier conditions later today as the high pressure controlling our wind pattern sinks southeast into the western North Atlantic. Slackening winds will reduce the speed convergence that has been sustaining the previously mentioned shallow showers. Looking upstream on CIMSS MIMIC PW, a mass of drier air over the Bahamas looks progged to advect in towards our area today. As such, have opted to stay with dime PoPs (basically normal at this time of year) for today and tonight. No significant changes to our sensible weather are in the pipeline for the rest of the forecast. The progressive wave currently in the Midwest CONUS will shift east passing north of our area with little fanfare in South Florida. Easterly breezes will prevail, first influenced the high pressure in the Atlantic before ridging sets back up along the Eastern Seaboard in the back half of the week. Throughout the work week, highs will reach up to the mid 80s with lows in the mid 70s. With no real airmass or wind direction changes, slight chance PoPs will continue throughout the forecast period as well. && .MARINE... Issued at 425 AM EDT Mon Apr 29 2024 A Small Craft Advisory is in effect for all Florida Keys coastal waters. From synopsis, a sprawling high pressure system centered southeast of New England will maintain fresh to occasionally strong easterly breezes early this morning. As the high presses south into the western North Atlantic, breezes will slacken, although occasionally fresh breezes will continue through the first half of the week. The aforementioned high moves east further into the mid to late week resulting in peaking and lulling easterly breezes. && .AVIATION... (06Z TAFS) Issued at 425 AM EDT Mon Apr 29 2024 Passing showers will be possible, mainly in the vicinity of EYW, early in the TAF period. Mainly dry conditions are expected after 12z. Near-surface winds will remain generally out of the east at 10 to 13 knots, with occasional gusts near 20 knots, especially through midday. && .CLIMATE...
