Area Forecast Discussion
National Weather Service Tallahassee FL
910pm EDT Monday Jun 21 2021

Intermittent showers and a few thunderstorms will be possible overnight, particularly across the northern portions of the area where it's not as worked over from today's convection.

.NEAR TERM [Through Tuesday]... A very active pattern for convection with the approach of a shortwave and cold front. Some locations across the Florida panhandle and big bend have already received 3 to 5 inches of rain since daybreak. In addition to very heavy downpours, some of the thunderstorms are producing gusty winds over 40 mph. While there will be a respite at times between showers and thunderstorms, rain chances will be elevated above seasonal levels through the overnight hours and Tuesday. For Tuesday, Storm Prediction Center has our entire CWA highlighted for a Marginal risk of severe weather. Some of the factors coming into play are a very moist airmass (PW > 2.0") and a low-level jet of around 30 kts. However, weak instability (~ 500-1000 J/kg) will be the limiting factor for a greater than marginal threat. Heavy downpours on top of recent rains over this past weekend and today will also cause concern for potential flash flooding with some riverine flooding also possible thereafter. See the Hydrology section at the bottom of this discussion for all the details.

Lows tonight wilL be around 70. It will be unseasonably cool on Tuesday due to the cloud cover with highs mainly in the lower to middle 80s.

.SHORT TERM [Tuesday Night Through Wednesday Night]... Mean trough will remain in place along the eastern seaboard through Wednesday night, with a decaying frontal boundary stalled across southern Georgia and Alabama. The airmass south of the boundary will remain very moist and supportive of high PoPs through Wednesday night. Heavy rain will continue to be a concern, especially across the Florida Panhandle, Big Bend, into far Southern Georgia.

With plenty of clouds for the next few days, afternoon temperatures will likely remain well below normal, with highs in the lower to mid 80s.

Long Term - Thursday Through Monday
The upper trough will weaken by Thursday, allowing for the return to a more typical summertime pattern of diurnal convection and temperatures reaching the upper 80s and lower 90s.
