.SHORT TERM...
(Today through Monday)
Issued at 343 AM EDT Sun Apr 28 2024

Key Messages:

-Quiet weather to finish out the weekend.

-Dewpoints will be on the rise tomorrow as the flow becomes more
southerly.

Another beautiful day today with SE winds and clear skies. Temps
will be in the mid 70s to low 80s across the CWA with minimum RH
values falling into the upper 40s and low 50s. While nice weather is
expected to continue, once the Bermuda high has a chance to get
settled off the GA coast, we`ll start to see more southerly flow
will will gradually start to increase our dewpoints as we come up
into the beginning of the long term.

.LONG TERM...
(Monday night through Saturday)
Issued at 343 AM EDT Sun Apr 28 2024

Looking at the forecast beginning Tuesday the overall sfc high
pressure retreats a tad to the east as a midlevel shortwave trough
moves through north Georgia. This shortwave indicates our next
change for precip mainly for areas north of ATL, but wouldn`t be
surprised to see showers and a few isolated thunderstorms affect
west central GA and portions south of ATL metro. CAPE values
generally are progged to be ~500 J/kg or less mainly due to peak
heating which would support isolated to scattered thunderstorms for
Tuesday.

Following the shortwave, the overall ridging pattern takes effect
again resulting in the warmest temps of the year as many areas in
central GA are forecast to either reach their first 90 degree day or
get very close on Wednesday and Thursday. Max temps will overall be
10-12 degrees above normal for this time of year.

Friday is our next decent chance at rain as a low pressure system
moves northward into the great lakes by the weekend, dragging a sfc
cold front into our area Friday into Saturday. With the temps in the
mid to upper 80s Friday, this could be an early return to the pulse
convection season as showers and scattered thunderstorms look to be
the primary threat into the weekend. The cold front will bring down
max Ts only marginally unfortunately with temps being only 5-6
degrees above normal instead of 10-12 degrees.
