The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before this special weather statement went out at Apr 5, 3:59 PM EDT, 2 hours 56 minutes earlier.
Area forecast discussion, Apr 5, 3:59 PM EDT, 2 hours 56 minutes before
Area Forecast Discussion National Weather Service Miami FL 359 PM EDT Fri Apr 5 2019 .DISCUSSION... SHORT TERM (Today through Sunday night) Convection has been slow to develop but is now beginning to flare up mainly west of the Lake. This is where highest PoPs exist through the evening, and scattered thunderstorms are expected. Sea/Lake breeze convergence in a warm/moist environment south of a front located near the FL/GA border is the main culprit for convective initiation, thus as instability wanes after sunset, so too will the convection. Until it does, somewhat cool air aloft could support a few wind gusts with the strongest cells, and cant totally rule out small hail - both of which should mainly be north of the region. Deep layer ridge builds in over the weekend, which will boost temperatures a bit and suppress rain chances. Southeast flow (relatively modest) will prevail, thus daily Atlantic sea breezes will intrude. Expect maxima and minima both a few degrees above normal, mainly being in the mid and upper 80s and upper 60s to mid 70s, respectively. LONG TERM (Monday through Thursday) Models are still showing a 500mb trough digging south over the Mississippi River Valley for the beginning of the week, and approaching South Florida Monday night and Tuesday.So, chances of convection do start to increase Monday, especially in the interior and the Lake region. Then models are showing widespread rain for Tuesday through Wednesday morning, as a weak cold front makes its way through the area. While PoPs are high due to the models, given their inconsistency with the weekends forecast, will keep the higher PoPs with a weary eye on future runs. && .MARINE... Thunderstorms are possible over Lake Okeechobee this afternoon and evening, with isolated thunderstorms possible each afternoon through early next week. Else, fairly benign conditions will prevail with southeast wind of 10 to 15 knots diminishing through the weekend and seas mainly being 3 feet or less. && .AVIATION... Primarily VFR conditions will prevail through the taf period with a slight chance for showers. SE winds will become more E to ESE tomorrow. && .BEACH FORECAST... Southeast wind will continue to subside this weekend, diminishing the risk for Atlantic rip currents. Still, residual beach conditions may be somewhat hazardous at least into Saturday, so at least Broward and Palm Beach counties' beaches may exhibit a moderate rip current risk Saturday. && .PRELIMINARY POINT TEMPS/POPS...
