NEAR TERM [Today]...
Early morning fog across the Florida Panhandle continues to slowly
erode this morning, with only lingering patchy fog around Panama
City westward to De Funiak Springs.
At the surface, our region remains to the west of a surface high pressure ridge. Aloft, a disturbance is moving through the Tennessee River Valley. With limited deep layer moisture, as noted on the morning sounding, any showers and storms will be isolated at worst, and likely remain to the north of our region today.
Still expect a good sea breeze circulation this afternoon which will result in temperatures a good 5 to 8 degrees cooler at the coast (lower 80s) than sites further inland where upper 80s to near 90 degrees are possible.
SHORT TERM [Tonight Through Sunday]...
Very Little change in thinking from the previous forecast, as 90 degree High Temperatures appear in store for much of the interior of our CWA over the upcoming weekend.
The one fly in the ointment will be the eastward progress of a closed Upper Level Low which is now moving through the lower MS Valley. The trof associated with this Low will likely provide just enough lift and instability to produce 20-30 percent PoPs during the afternoon hours, especially across northern and eastern portions of the region, before Upper Level Ridging builds in from the west thereafter.
LONG TERM [Sunday Night through Thursday]...
Deep layer ridging is expected over the Southeast U.S. through mid
week. A weak trough is forecast to develop later in the work week.
The GFS and ECMWF differ on exactly when and how much this trough will develop. Regardless, the NWP guidance consensus is close to climatology for PoP and temperatures. The PoP will be in the 20-30% range through the period, mainly during the afternoon and early evening hours. It will be a warm period, especially given our
relatively cool spring so far, with highs near 90 and lows in the
AVIATION [Through 12z Friday]...
Lingering fog dissipating quickly this morning.
Only ECP shows LIFR conditions as of 13z, but this will improve quickly.
VFR all sites after 14z with another round of fog expected overnight,
potentially once again into the IFR/LIFR range.
Generally light onshore winds and low seas will dominate our coastal
waters for the next several days, with just some minor increases near the coast with the afternoon sea breeze.
Relative humidity levels will remain above critical thresholds for
the next several days.
Therefore, red flag conditions are not anticipated.
Area rivers and streams will remain well below flood stage for the
next several days with very little rain in the forecast.
