GMZ700 Synopsis For The Suwannee River To Okaloosa-walton County Line Out To 60 Nm 1036 Am Edt Sun Sep 27 2020
Synopsis.. Light winds less than 10 knots and seas generally less than 1 foot will create rather favorable boating conditions through Monday prior to the arrival of a rather energetic upper level trough and associated cold front. The chances of showers and Thunderstorms will exist across all waters starting today, and persist through the eventual frontal passage Tuesday night. Behind the cold front, brisk northwest winds may possibly reach advisory levels at times Tuesday evening through Wednesday. Winds are expected to remain elevated at cautionary levels through the end of the work week.

Area Forecast Discussion National Weather Service Tallahassee FL 627 AM EDT Sun Sep 27 2020

AVIATION. [Through 12Z Monday]

Ceilings will transition from VFR to MVFR as precipitation moves into the terminals - late this morning at ECP and by early this afternoon elsewhere. While precipitation ends this evening, cigs will lower to at least IFR for for all terminals, except at ECP, where MVFR should prevail. Easterly winds at or below 5 knots.

PREV DISCUSSION [312 AM EDT].

NEAR TERM [Through Tonight].

The main concern today is the potential for periods of heavy rain, mainly in the FL Panhandle near the Apalachicola River and west. This could result in minor flooding, with the potential for flash flooding remaining low. The pattern features a seasonably strong southwest flow aloft advecting a very moist air mass characterized by Precipitable Water values around 2.2 inches - which is near the daily maximum per SPC Sounding Climatology. An east-west oriented surface trough is expected to develop near the coast and slowly move north toward the I-10 corridor. This will be the focus for the heavier rainfall, aided by divergence from the nearby upper jet. Average rainfall amounts of 1-2 inches are expected over the FL Panhandle, highest near the coast, tapering off elsewhere. Localized amounts of 3-4 inches south of I-10 in the FL Panhandle are possible, especially along the Emerald Coast. Flash Flood Guidance is on the high side for these amounts, so the probability of exceeding them is low, but minor flooding of urban and poor drainage areas is possible. A drying trend is expected tonight.

Instability will be greater over the gulf waters south of the Emerald and Forgotten Coasts, where shear profiles could favor some rotating storms, which could lead to waterspouts. These should remain over the water given the lack of instability and Convective Inhibition over the land.

Given the extensive cloud cover and precipitation today, sided with the lower of the guidance. Highs in the upper 70s to lower 80s are expected, several degrees below normal. The exception will be the Southeast FL Big Bend, where mid-80s are forecast.

SHORT TERM [Monday Through Wednesday Morning].

A rather energetic long wave upper level trough is expected to dig south out of the central plains, and into the southeast Tuesday through Wednesday. As the main upper level trough digs south out of the central plains, a secondary vorticity maxima is expected to eject equatorward out of Minnesota and quickly merge at the base of the aforementioned long wave trough over the central northern Gulf Coast. This energetic evolution in the mid and upper levels of the atmosphere will generate strong upper level divergence over our region on Tuesday and Wednesday as surface cyclogenesis responds to the upper level dynamics. Fortunately for our area, the surface cyclone is expected to mainly develop east of our region as high pressure and strong northwesterly flow associated with the surface high pressure behind the upper level trough quickly pushes into the region. At this time, the severe weather threat looks low as the better chances push off to the east with the developing surface cyclone and associated cold front that will have already pushed east of the region. There still remains the chance that portions of our far eastern zones could see a few stronger storms Tuesday afternoon; however, those chances remain low. Trailing the cold front, will be much cooler and drier air from the previously discussed surface high pressure system. The northwest winds behind the cold front on Tuesday and Wednesday will remain brisk as the pressure falls to the east of our region occurs from the previously discussed surface cyclogenesis. Temperatures ahead of the front on Tuesday will likely reach the low 80s, meanwhile behind the cold front temperatures will likely only reach the low 70s. Lows overnight Tuesday into Wednesday are expected to fall well into the mid 50s for the entire region as the base of the upper level trough and associated depressed tropopause are directly over our region.

LONG TERM [Wednesday Through Sunday].

High pressure and sunny weather will predominantly take over once the cold front has cleared the region Tuesday evening. With high pressure overhead, the chances of rain are near zero for the entirety of the long term period. Temperatures will remain comfortable as highs in the mid 70s to low 80s across the region are expected through this period. The drier air at the surface will lead to fairly beautiful weather. Temperatures at night will feel like fall as lows fall into the low to mid 50s through the period.

MARINE.

Light winds less than 10 knots and seas generally less than 1 foot will create rather favorable boating conditions through Monday prior to the arrival of a rather energetic upper level trough and associated cold front. The chances of showers and thunderstorms will exist across all waters starting today, and persist through the eventual frontal passage Tuesday night. Behind the cold front, brisk northwest winds may possibly reach advisory levels at times Tuesday evening through Wednesday. Winds are expected to remain elevated at cautionary levels through the end of the work week.

FIRE WEATHER.

Low dispersions are likely across portions of the area today and Monday. Otherwise, there are no other fire weather concerns over the next several days.

HYDROLOGY.

The Choctawhatchee and Chipola rivers remain in flood today, with both the Choctawhatchee River at Bruce and the Chipola River at Altha in minor flood. Each of these rivers will continue a slow fall over the next several days. A few locations today may receive higher rainfall totals than expected, especially along coastal regions as storms training from the near shore waters linger along the panhandle this afternoon. These regions should be watched for nuisance flooding later this afternoon especially given that soils are already saturated from rainfall from Sally just a week and a half ago.

SPOTTER INFORMATION STATEMENT.

Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur (while following all local, state, and CDC guidelines) by calling the office or tweeting us @NWSTallahassee.
