Version 3.4 |
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. |

Area Discussion for - Miami-South Florida, FL
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 230805 afdmfl area forecast discussion national weather service miami fl 405 am edt Mon apr 23 2018 Discussion A sprawling low pressure system at the surface and aloft is over the tennessee valley this morning, with a cold front extending southwest into the western gulf of mexico. Winds currently veering to the south as the storm system moves east and the high over the mid- atlantic moves northeast. South florida is in an established warm sector, with a moist and unstable air mass in place. Showers have focused overnight in a corridor of better moisture and confluence embedded in the SE low level flow over the northeast part of the area, with only isolated activity elsewhere. For the next few hours, with little organized focusing mechanism for ascent, expect only isolated showers most areas. With some surface heating this morning, sea breezes should be able to move inland from both the atlantic and gulf coasts, and a lake okeechobee breeze may develop as well. With the moist and unstable air mass in place, showers and thunderstorms should fire along all of these boundaries by early afternoon. As convection deepens, mean wsw winds in the cloud bearing layer should allow for convection and or outflow boundaries to have a preferred ene motion toward the east coast urban corridor, particularly broward palm beach counties. Forecast soundings indicate plenty of instability, dcape of 1000-1200 j kg, veering winds with height, and 20-30 kts of bulk shear, so a few strong thunderstorms will be possible. Frequent lightning, heavy downpours, and gusts up to 50 mph will be the main hazards. Stabilization in the wake of the convection, nocturnal cooling, and dissipating boundaries should allow shower coverage to decrease a bit overnight, but still pops will remain in the slight chance to chance range. Light south winds and high dewpoints over areas with recent rainfall should allow some patchy fog to develop over the interior late tonight. Tuesday, the front gets closer and winds continue to veer around to southwest. Expect the gulf sea breeze will move across the state and collide with the atlantic sea breeze near the east coast urban corridor, firing off convection during the day focusing especially on the northeast part of our area. A few strong thunderstorms and heavy downpours will again be a threat. By late evening and overnight, the front becomes detached from the retreating upper low with decreasing convergence along the boundary, which along with nocturnal cooling and post-convective stabilization should steadily decrease shower and thunderstorm chances as the front pushes through the southernmost part of the area. Wednesday and beyond: drier and more stable air moves into the area behind the front. Late in the week into the weekend a couple of shortwave troughs in the northwest flow behind the mean |
eastern us longwave trough may force some reinforcing boundaries into the area, but still some disagreement in the medium range models on exact timing of the best shower chances, so forecast pops for now are a broad-brushed in the slight chance category. Marine Mostly slight seas, with light to moderate south to southeast winds today but dominated by sea breeze circulations this afternoon. Winds veer around to southwest tomorrow. Scattered to numerous thunderstorms lake okeechobee and the atlantic waters at times through Tuesday night, with more isolated activity in the gulf waters. Locally higher winds and waves are expected around any thunderstorms. Winds turn to moderate northwest late Tuesday night into Wednesday behind a front with drying conditions. Aviation Hit and miss showers may continue over the atlantic for the next several hours and push inland and north along the coast periodically through the morning hours. However, confidence south of kpbi is too low to include mention of vcsh in the TAF package for this morning with pops overall well under 50%. Towards late morning, showers may increase again, with a chance of thunderstorms starting around 23 1500z, mainly for the interior portions of florida and TAF sites north of kmia on east coast. Some storms may decrease vis to below 3sm with ra+ but given lack of confidence of any one hitting a particular site am handling it right now with vcts and will amend as needed during the day. Expect south southeast 5-10 kts winds through the period along the atlantic, around 10-15 kts late morning and afternoon, with kapf turning south southwesterly 5-10 kts around 16- 18z but otherwise south southeast 5-10 kts after sunrise this morning and light and variable overnight. Beach forecast A high risk of rip currents will persist today at the palm beaches, with a moderate risk at the atlantic beaches of broward and miami-dade county. The risk tomorrow is currently expected to be moderate at the palm beaches.
