GMZ700 Synopsis For The Suwannee River To Okaloosa-walton County Line Out To 60 Nm 234 Pm Edt Fri Jun 14 2024

Synopsis -
the prevalence of tropical moisture over the gulf keeps daily chances for Thunderstorms in the forecast. Southeast winds generally 10 knots or less prevail through the weekend before becoming easterly. By early next week, a tightening pressure gradient between the bermuda high and tropical disturbance over the bay of campeche initially brings cautionary conditions to our waters with advisory level and winds and seas likely on Tuesday, especially west of ochlockonee river.

New SYNOPSIS, NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER, HYDROLOGY

SYNOPSIS
Issued at 249 PM EDT Fri Jun 14 2024

Hot and mostly dry weather expected through the weekend with widespread 90s (isolated 100) and triple-digit heat indices forecast.

Warm and muggy weather prevails next week with daily chances for showers and thunderstorms initially confined closer to the coast, then having better coverage inland late in the period.

Hazardous marine conditions are likely to begin as soon as Monday.

NEAR TERM
(Through Saturday)
Issued at 249 PM EDT Fri Jun 14 2024

Surface high pressure will continue to hold over the region on Saturday, with an upper level high building in from the west. This will lead to an unseasonably warm day on Saturday with high temperatures peaking in the mid to upper 90s, with some areas topping out near 100. The Heat Index temperatures, the feels like temperature, will be hot too and range from about 100-107 degrees. High pressure should suppress any shower or thunderstorm development, but there's a possibility the seabreeze might be able to help develop a few isolated storms along the FL coast. Outside of that, mainly dry weather is in store for the period.

SHORT TERM
(Saturday night through Sunday night)
Issued at 249 PM EDT Fri Jun 14 2024

A strong mid-upper ridge gradually treks across the SE US into early next week, thus keeping unseasonably hot weather in place. The uptick in moisture via SE flow from the Bermuda High increases cloud cover/rain chances and decreases our air temperatures to the 90s on Sunday. However, the higher humidity compared to Saturday should yield triple-digit heat indices ranging from about 101-106 degrees.
Although these values fall short of our local advisory criteria of at least 108, sensitive groups are still vulnerable to such conditions. Muggy overnight lows in the mid 70s won't provide much heat relief, but afternoon thunderstorms may, for which the best potential is from roughly the I-10 corridor, southward.

LONG TERM
(Monday through Thursday)
Issued at 249 PM EDT Fri Jun 14 2024

The aforementioned ridge pivots NE, then anchors itself over the Mid- Atlantic states with an extensive upstream upper trough setting up across the Western US and a tropical disturbance likely brewing in the Bay of Campeche to start the long-term period. This synoptic pattern ushers a robust easterly flow regime as the regional pressure gradient tightens in addition to a long-fetch "conveyor belt" of tropical moisture surging towards the Northern Gulf Coast.

As a result, we are looking at a heterogeneous distribution of rain chances from north to south for much of the coming week at this time. The greatest potential at this time is along/south of the coast where the greatest moisture is expected to reside, though trends may change depending on how the atmosphere evolves. By Thursday, higher PoPs are painted northward as deeper moisture attempts to spread more inland off the Gulf while the Atlantic seabreeze gets going.

While conditions will be warm and muggy, high temperatures trend more to the low/mid 90s given the increased cloud cover. Low to mid 70s hold for overnight lows.



AVIATION
(18Z TAFS)
Issued at 249 PM EDT Fri Jun 14 2024

Fair weather cumulus has developed over the region this afternoon and are accompanied with some breezier northeast winds. Expect some gusts to 12-18kt gusts being possible over the next couple of hours, with winds decreasing as we lose daytime heating and sunlight. Then skies clear, leaving us with calm overnight conditions. Tomorrow, high pressure should be taking control of the forecast. This should help suppress shower and thunderstorm development, though some of the CAMS try to have some popcorn activity trying to develop. Confidence is too low to add any mention in the TAF lines.



MARINE
Issued at 249 PM EDT Fri Jun 14 2024

The prevalence of tropical moisture over the Gulf keeps daily chances for thunderstorms in the forecast. Southeast winds generally 10 knots or less prevail through the weekend before becoming easterly. By early next week, a tightening pressure gradient between the Bermuda High and tropical disturbance over the Bay of Campeche initially brings cautionary conditions to our waters with advisory level and winds and seas likely on Tuesday, especially west of Ochlockonee River.

FIRE WEATHER
Issued at 249 PM EDT Fri Jun 14 2024

The main fire weather concerns through this coming Monday are high dispersions across the region. Outside of that, there will also be unseasonably hot temperatures over the weekend where highs peak in the mid to upper 90s, perhaps even making it to 100 on Saturday.
Heat Index values, the feels like temperature, will range from 100 to 107 degrees. High pressure should keep us dry Saturday, with a moisture surge returning Sunday and into early next week. This should bring typical summertime afternoon showers and thunderstorms.

HYDROLOGY
Issued at 249 PM EDT Fri Jun 14 2024

Prospects for significant flooding over the next several days still appear minimal. Mostly dry weather is forecast through tomorrow before rain chances modestly increase on Sunday. Of course, localized runoff issues are always possible from strong and/or slow- moving thunderstorms, especially in urban/low-lying/poor-drainage areas. The axis of greatest precipitation aims to remain just offshore and focus more over the Northern Gulf coast next week. In terms of rivers, all are below action stage.
