&&

.SHORT TERM...
(Today through Tuesday)
Issued at 219 AM EDT Mon May 4 2026

High pressure across the region will keep mostly clear skies over
the state today with some increasing clouds Tuesday. The ridge is
elongated with the axis angled from NE to SW across central GA.
The main center of the ridge moves east through the day and slowly
weakens its grip on the state through Tuesday afternoon. We will
see increasing cloud cover from the NW ahead of the next system
that will bring increased precip chances to the state in the
extended periods. Dry conditions will continue with minimum
Relative Humidity values slowly increasing in the short term. With
the ridge slowly moving out the winds turn to the SW allowing
Gulf moisture to slowly increase across the region. RH values will
dip down into the lower 30s today but with the light SW winds a
fire danger statement should not be needed. The RH values will
still need to be monitored today as the RH values could get very
close to critical thresholds (<30%). RH values Tues will dip down
into the upper 30% to lower 40% range so not expecting any fire
weather concerns.

One big thing this ridge will do is allow temps to rebound to near
and slightly above seasonal norms. Will see temps today mainly in
he 70s to near 80 with highs Tuesday in the upper 70s to middle
80s. Low temps will get down into the 50s Tue morning.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 219 AM EDT Mon May 4 2026

Another front is expected on Wednesday and into Thursday. While this
front is still a few days out, models are in good agreement that
plenty of instability will build during the day on Wednesday.
Temperatures will climb into the low to mid 80s with dewpoints in
the low 60s. The GFS forecast soundings, as a result generate enough
instability to warrant us keeping a close eye on the forecast as it
evolves over the next few days.

Temperatures in the upper 70s and low 80s will cool falling the cold
front Thursday into Friday. Highs will reach the 70s areawide and
overnight lows in the 40s and low 50s. Rain chances may linger into
the weekend.
