CohenWhat forecasters said that day
The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at May 7, 1:53 PM EDT, 1 hour 16 minutes earlier.
Area forecast discussion, May 7, 1:53 PM EDT, 1 hour 16 minutes before
Area Forecast Discussion National Weather Service Miami FL 153 PM EDT Tue May 7 2019 .AVIATION... Convection has developed near Miami-Dade terminals and will likely continue for a few hours. Expect thunderstorms to develop over/west of Broward sites and also inland of Naples this afternoon, with activity persisting through mid-evening. Thereafter, dry TAFs but can't rule out isolated showers coming inland from Atlantic. Similar pattern for Wednesday morning, before afternoon convection likely focuses well inland of terminals. Onshore flow 10 KT or less today, becomes calm tonight, then E at 5-10 KT Wednesday. && .PREV DISCUSSION... /issued 1215 PM EDT Tue May 7 2019/ MESOSCALE UPDATE... Visible satellite loops and surface observations reveal a variety of foci for potential diurnal convective development during the afternoon hours today: (1) An arc of differential-heating-induced baroclinicity flanks the east-northeastward protruding anvil plume cast downshear of a regenerative multicell convective cluster over the Gulf waters -- arching from central Collier County through central Broward County through northwest Miami-Dade County and northern Mainland Monroe County. Ascent accompanying related baroclinic circulations will have the potential to support initial convective development through 2 PM in the vicinity of the arc identified above. (2) A weak sea-breeze boundary is becoming evident along the East Coast vicinity -- especially in areas removed from the cirrus canopy accompanying the aforementioned anvil plume. Boundary-layer cumulus congestus along the sea-breeze boundary is becoming most agitated where diabatic heating from insolation has been strongest, and especially where this boundary intersects the anvil-peripheral baroclinic zone. This includes areas from southeast Broward County to central and eastern Miami-Dade County. The continued westward advance of the sea-breeze boundary, aided by some westward-advective component of the low-level flow south of ridging to the north -- may also encourage initial convective development across interior South Florida through 2 PM -- particularly over western parts of Miami-Dade County. (3) Westward-moving, though decelerating, amalgamated outflow boundaries are presently approaching the East Coast from the Atlantic coastal waters. Related boundary-layer convergence will have the potential to reinforce ascent along the East Coast this afternoon. Whether related ascent is efficient at supporting convective development will depend upon the degree of stabilization preceding the inland spread of the sea breeze and any augmentation from diurnal convective development. With initial storm formation expected through 2 PM owing to the very moist boundary layer containing negligible convective inhibition, and given the modest inland spread of the Atlantic sea breeze, there is some possibility that initial convective development may be in somewhat close proximity to the East Coast Metro Areas -- even if more vigorous development also occurs over the interior. Present indications are that areas from central Mainland Monroe County through central Miami-Dade County and into central Broward County would be the areas of greatest potential for the most vigorous convective development -- on the flank of the cirrus plume and its intersection with sea-breeze boundaries and reinforcing-outflow- related convergence. However, with little mass convergence noted in the low-levels based upon surface observations and mesoanalysis data, the development of convection should occur slowly, and it may not be until as late as 2-4 PM when more vigorous updrafts develop. The Miami observed sounding indicates modest moistening of the lower/middle troposphere during the past 24 hours, with one-quarter inch increase in the precipitable water value and a 0.2-g/kg increase in the lowest-100-mb mean mixing ratio value. The boundary- layer moistening has been offset by a slight decrease in maximum lapse rates aloft by about 0.3 C/km, yielding similar magnitudes of boundary-layer-based buoyancy. As a result, buoyancy profiles aloft appear slightly narrower in some portions of the midlevels, which may temper convective-scale upward accelerations. Moreover, with effective bulk shear values having decreased from around 30 kt to 20 kt during the past 24 hours, updraft/downdraft separation could be somewhat suppressed and mitigate overall convective organization. However, upper-tropospheric flow has strengthened from around 40 kt to 55 kt ahead of a minor low- latitude perturbation approaching the area per water-vapor loops. This will enhance the degree of convective ventilation and potential for convective sustenance, and even weak rotation in the upper reaches of the convective updraft. This should facilitate the sustenance of deeper updrafts, which will have a tendency of developing southeastward owing to cross-deep-shear flanking dynamic perturbation pressure gradient forces. Related dynamic lifting will further be supported by the weak low-level easterly flow established beneath the boosted high-level west- southwesterly flow. Given a convective mode characterized by sustained single cells exhibiting transient mid/high-level weak rotation amid weak midlevel lapse rates -- the hail potential will be non-zero though any hail should be small in size. The lack of stronger effective bulk shear, and related low confidence in upscale growth, along with limited midlevel lapse rates, should temper the convective-wind risk. However, an outside chance for water-loading-enhanced microbursts capable of very isolated damaging winds cannot be ruled out where individual cold pools merge amid the steepest low-level lapse rates -- south of the aforementioned cirrus plume. Otherwise, the higher PW and slow storm motions will enhance the heavy- rain/localized flooding potential, especially where convective training occurs. Given only modest components of anticipated cell motion parallel to initiating boundaries, flooding potential could be mitigated, though non-zero where outflow-induced augmentations to low-level convergence fields favor more boundary-parallel storm motions. This potential would maximize in the 4-7 PM time frame, once established convection has already fostered the establishment of cold pools. PREV DISCUSSION... /issued 952 AM EDT Tue May 7 2019/ UPDATE... With a quite similar air-mass to previous few days, expect another round of showers and thunderstorms to develop near/inland of sea- breeze boundary shortly after midday. Overall wind flow is lighter than few days and less southwesterly in nature, so activity may remain more focused over interior areas than previous few days, and also may develop along Gulf breeze. Still, at least some scattered activity is expected across east coast urban areas, particularly in western suburbs. Moderate instability and fairly cool temperatures aloft will support some strong downburst wind gusts, with some small hail possible. Locally heavy rain may induce some urban flood problems as well. Overall, the forecast has changed little. PREV DISCUSSION... /issued 153 AM EDT Tue May 7 2019/ DISCUSSION... A weak cold front located over Central Florida early this morning will continue to move slowly southward into the Lake Okeechobee region today before stalling and washing out tonight. This will allow for the west and east coast sea breezes to develop and push inland. The best coverage today should be a little bit further inland over the eastern interior areas, but the east coast metro areas will still see scattered coverage . The left over activity should then push back to the east coast metro areas this evening before dissipating, due to the mid to upper level flow is still from the westerly direction. High pressure over the Southeastern United States will then build a little bit further southward into the Florida Peninsula for the middle to end of this week. This in turn will allow for more of a easterly wind flow over South Florida focusing the best coverage each day over the interior and west coast metro areas. However, the east coast metro areas will still see some showers and a few thunderstorms during the late night and morning hours. EXTENDED FORECAST... The high will break down this weekend over the Southeastern United States, as another cold front will be approaching the Southeastern United States. This will allow for the wind flow to swing more to a southerly direction and focus the shower and thunderstorm activity more over the interior areas. The front will continue to move slowly southward early next week down the Florida Peninsula allowing the for the steering flow to become more southwest over the region. This will once again focus the shower and thunderstorm activity over the east coast metro areas early next week. MARINE... The winds will the easterly today through end of the week, as the wind speeds will be at less than 10 knots today increasing to 10 to 15 knots for middle to end of the week. This will keep the seas below 6 feet in both the Atlantic and Gulf waters through the week. Therefore, boating conditions looks good over South Florida waters through the week outside of any showers or thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
