Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
255 PM EST Fri Jan 22 2021

.DISCUSSION...
Weakening cold front will sag south into the forecast area
Saturday leading to abundant clouds and a few showers for areas
from around Tampa Bay and the Interstate 4 corridor northward. The
southwesterly flow out ahead of the boundary will continue to
bring slightly warmer moister air into the region leading to areas
of fog, some locally dense, late tonight into Saturday morning.
During Saturday night and Sunday high pressure well to the north
will bridge the boundary shifting winds to east to northeast
bringing some slightly drier into the area, but this will be short
lived as the high moves out into the western Atlantic Ocean early
next week veering low level winds to a more southerly direction
once again. The threat for late night/early morning fog will
persist through midweek, then a stronger cold front is expected to
move through Thursday bringing our next shot of cooler drier air
to end the week.

Temperatures will remain near to a few degrees above normal this
weekend, then a few to several degrees above normal for the first
half of next work week before the next stronger cold front moves
through late in the week.

&&

.AVIATION...
Mainly VFR conditions are expected into early tonight, then some
areas of MVFR/local IFR conditions could develop and continue
through Saturday morning. Southwest winds at 7 to 11 knots will
diminish and become light tonight.

&&

.MARINE...
Weak high pressure will remain across the area early tonight with
south to southwest winds across the waters. Some patchy to areas
of sea fog could develop later tonight into Saturday as slightly
warmer moister air spreads north ahead of a weakening cold front.
This boundary will settle over the waters during Saturday with
another area of high pressure to the north building into the
waters shifting winds to east northeast. Early next week winds
will veer around to the south once again as the high to the north
moves out into the western Atlantic Ocean with the chance of more
sea fog returning by Tuesday.

&&

.FIRE WEATHER...
Relative humidity values will remain above critical levels through
the weekend with dispersion values on the low side, especially
Saturday.
