10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working.

Area Forecast Discussion National Weather Service Miami FL 314 AM EST Mon Dec 16 2019
Short Term (Today through Tuesday Night). A rather complex weather pattern dominates much of the central and eastern CONUS with large- amplitude troughing extending from east Texas through much of the Atlantic seaboard, while the deep SE states and the FL peninsula continue to enjoy the influence of relatively stable and benign weather thanks to the dominance of a broad high pressure system centered over the west Atlantic.
Latest sfc and model analyses show the high pressure ridge at the lower levels, while mainly zonal flow dominates aloft over the area, keeping generally easterly flow across SoFlo today. Models gradually migrate the ridge eastward and into the west Atlantic during the short term, which will strengthen a little more the pressure gradients over the region. This will result in periods of gusty winds this afternoon, possibly in the 20-25 mph range at times, mainly over the Atlantic coast areas.
With the prevailing E/SE flow, low-level moisture gradually increases and brings a warming trend today with afternoon highs climbing into the mid 80s. It will also push a few passing showers over the eastern half of SoFlo this afternoon, but any shower that forms should be brief.
Meanwhile, model solutions suggest the deepening/consolidation of the trough across the eastern seaboard into a large deep low near the NE states, which sends an associated frontal boundary into the northern FL peninsula by early Tuesday. This in turn will bring veering winds to a more southerly flow, which in turn increases moisture advection from the Caribbean/SW Atlantic waters. Therefore, as daytime heating provides added BL instability, expect increasing shower/convective activity on Tuesday afternoon with scattered to numerous showers, along with a few possible thunderstorms. With the southerly flow in place, best chances for deep convection will reside over interior and northern areas.
Temperatures on Tuesday afternoon will again hit the mid 80s across much of SoFlo, with nighttime lows mostly in the 60s.
Long Term (Wednesday through Sunday Night). Showers and a few thunderstorms are expected Tuesday Night into Wednesday morning as a cold front pushes through the area, with the greatest instability and thunderstorm potential out over the waters. Right now high temperatures are forecast to range from near 70 west of the Lake to the low 80s across the far southern Peninsula, which is a touch higher than previous forecasts due to a slight slowing in the frontal timing. Since the front is forecast to push through in the morning, any timing changes could have a significant impact on forecast highs for the day. Breezy northerly winds are expected in the wake of the front Wednesday before becoming more northeasterly on Thursday. Wednesday Night is forecast to be the coldest of the period with low temperatures ranging from the mid 40s west of the Lake to the low 60s right along the East Coast.
Winds gradually become easterly on Friday but remain breezy with strong surface high pressure over the mid Atlantic states and developing low pressure somewhere around the southeast Gulf. The forecast for the weekend remains interesting with some fairly significant feature and timing differences between the models. Both GFS and ECMWF show a mid to upper trough digging southeastward into the Eastern Gulf with a surface low pressure system developing somewhere in the eastern to southeastern Gulf next weekend. GFS develops and keeps the low further south, with a much faster track across the Keys and Bahamas on Saturday. ECMWF is slower, developing the low in the eastern Gulf and then deepening it some off the Florida West Coast before dragging it across the state Saturday Night or Sunday. Either solution could potentially pose impacts for our area, but that largely depends on the strength, track and timing of the system. In general, a faster solution would probably be less hazardous as the low could deepen off the Southeast CONUS coast instead of while it's still in the Gulf. A faster solution would also give less time for moisture return in the wake of Wednesday's front, although as the solutions trend later and later it appears that will be less of an issue. Track of the system will be critical regardless of timing, as a track closer to South Florida would increase our chance for heavy rainfall and/or severe weather.
Marine. High pressure dominates the coastal waters through Tuesday, with persistent easterly to southeasterly flow. A cold front boundary reaches the area by mid-week, bringing potential for hazardous conditions over the coastal waters for the later part of the work week.
Aviation. VFR expected to prevail during the next 24 hours at all terminals. Although there are low chances of some showers this afternoon over the Atlantic terminals, will keep mention of rain out of the TAFS attm and update as necessary. Mainly ESE winds prevail during the forecast period, becoming gusty at times after 14Z.
