Area Forecast Discussion

356 AM EST Fri Mar 5 2021


.SHORT TERM /Today through Saturday/...

Medium-range models in good agreement through the short-term
forecast period. Closed upper low approaching today as it sweeps
through the high-amplitude longwave pattern opens up and weakens as
it swings through the region tonight/Saturday. Models keep any
surface low development associated with this system well south of
the state over the northern Gulf of Mexico. Better moisture remains
well south as well with forecast precipitable water values
struggling to exceed 1/2" across the forecast area. Can`t rule out a
few light sprinkles reaching the surface across the forecast area
tonight, but chances remain too low to include in the forecast for
now. Main impact from this system will be increasing clouds today
with mostly cloudy skies tonight through much of Saturday. Should
see some clearing working into the forecast area from the west/
northwest by the latter half of the day Saturday. Temperatures
remain near seasonal normals in general, slightly above today and
slightly below Saturday.

.LONG TERM /Saturday Night through Thursday/...

Deep eastern states upper trough will gradually move off the
Atlantic Coast keeping us in a dry northwest flow aloft into the
first of next week. By mid week...the flow flattens and
transitions into a more west to southwest pattern. Strong high
pressure centered in the western Atlantic tends to keep the deeper
moisture to our north and west. So...basically dry for the entire
period. Temperatures start out on the cool side but gradually
warm through the week.

.FIRE WEATHER...

Although slightly cooler afternoon temperatures will limit the
coverage and duration, several hours of relative humidity values
around or below 25 percent are likely across much of west-central
and north Georgia this afternoon. 10-Hour fuel moisture values and
wind speeds are expected to remain below Red Flag criteria, however
we will be issuing a Fire Danger Statement for the area generally
north and west of a line from around Columbus to Athens for this
afternoon.

AVIATION...
06Z Update...

VFR conditions will predominate across the forecast area through the
forecast period. High-level cloud coverage increases through the
daytime today with mid-level clouds increasing by 00-06Z. Cannot
rule out some light showers across the area after 00Z, but coverage
should be sparse. Northwest to north winds 6kt or less become north
to northeast 3-7kt by 12-15Z but are expected to edge back to north/
northwest by 19-21z across the Atlanta Metro TAF sites.

//ATL Confidence...06Z Update...
Medium confidence on wind direction timing. High confidence on all
other elements.
