Area forecast discussion, Jul 3, 1:57 PM CDT, 1 hour 52 minutes before

Area Forecast Discussion
National Weather Service Tallahassee FL
257 PM EDT Wed Jul 3 2019

.NEAR TERM [Through Tonight]...

The scattered showers and thunderstorm activity were seeing tonight
will diminish this evening with quiet conditions expected for the
overnight hours. The humid airmass in place won't be going anywhere
anytime soon so expect muggy conditions with lows around the mid
70s. Patchy fog is possible overnight, especially in locations that
receive rain this afternoon.

.SHORT TERM [Thursday Through Friday Night]...

Deep layer ridging will retrograde from the eastern gulf to the
western gulf by Friday night. This will bring increasing
instability and moisture to our region. Forecast PWs will be at or
above 2.0" through the period. The forecast PW at TLH is as high
as 2.41" both Thursday and Friday night. This may not bode well
with planned firework displays. PoPs will be tapered 40-50% west
to 50-60% east Thursday and likely (60-70%) all zones Friday.

In addition to the increased chances for storms, temperatures
will remain higher than normal. Highs are forecast to be in the
mid-upper 90s Thursday with heat indices in the 105-110 range.
Friday will be slightly closer to normal, with highs in the low-
mid 90s.

.LONG TERM [Saturday Through Wednesday]...

The active pattern will continue through the weekend into the
middle of next week. PoPs will generally be around 60% each
afternoon. The higher coverage in storms over the next several
days will give us a little relief from the heat, with highs in the
low 90s from Saturday through mid-week.

&&

.AVIATION...
[Through 18Z Thursday]

VFR conditions are expected to prevail. However, scattered
thunderstorms this afternoon may provide tempo restrictions. Winds
will be light away from convection but gusty near thunderstorms.

&&

.MARINE...

Chances for showers and thunderstorms are forecast for the next
several days. Outside of thunderstorms, winds will be 15 kts or less
with seas of 3 feet or less.

&&

.FIRE WEATHER...

Red flag conditions are not expected over the next few days as
relative humidity values will remain above critical levels.
Dispersions will however be low across the region both Thursday
and Friday.

&&

.HYDROLOGY...

Scattered to numerous showers and thunderstorms are forecast each
afternoon through the weekend and into early next week. Heavy
rainfall rates will be possible in some of these storms, which could
produce localized flooding. However, there are no widespread
flooding concerns expected for the next several days.

&&

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @NWSTallahassee.
