...Mid-Morning Update...

.UPDATE...
Issued at 940 AM EDT Fri May 3 2024

Forecast remains on track for this morning. Showers ongoing across
northern and east central Georgia will continue to push eastward
and out of our area, with a secondary wave of precipitation to
enter from the AL/GA border early this afternoon. Lingering
moisture and warmer-than-average temperatures will make for a
balmy afternoon.

.SHORT TERM...
(Today through Saturday)
Issued at 320 AM EDT Fri May 3 2024

High pressure at the surface will continue through the period. The
mid levels will be a bit active with several shortwaves impacting
the CWA through the short term period of the forecast.

500mb analysis shows ridging along the eastern seaboard with SW flow
across much of GA. A couple of shortwaves are noted within the flow,
one across far NE MS/NW AL, one across the ARKLAMISS and two
stronger ones across across eastern TX/OK. Each one of these waves
will bring the potential for shra and tsra to the CWA through the
short term. Models do have trouble initializing these system, which
impacts timing. The early morning shortwave could bring isolated
shra to portions of north GA early this morning. Little, if any,
measurable rainfall is is likely. The second shortwave, back over
the ARKLAMISS, will most likely move through during the afternoon,
helping to fire/sustain isold/scat convection this afternoon and
evening. The stronger shortwaves back across TX/OK will continue to
move east through the period within a slightly negatively tilted
trough. This feature will likely impact the CWA on Saturday,
bringing greater coverage of storms than today.

With PWATs in excess of 1.5" and very light BL winds (slow
movement), thunderstorms this afternoon and Saturday will be capable
of producing locally heavy rainfall. A few strong thunderstorms will
be possible this afternoon and Saturday. Gusty winds and frequent
lightning will be the primary hazards. An isolated severe
thunderstorm cannot be ruled out either day, but widespread severe
weather is not anticipated.

High temps the next couple of days will run 5 to 10 degrees above
normal.

.LONG TERM...
(Saturday night through Thursday)
Issued at 320 AM EDT Fri May 3 2024

A fairly unsettled period will be ongoing at the start of the
extended forecast period. Another in a series of shortwave
disturbances within the midlevel near-zonal flow will traverse the
region on Sunday and again on Monday, bringing continued elevated
scattered to numerous shower and thunderstorm coverage. Coverage
will be diurnally enhanced, though some activity is likely to linger
into at least through the evening. The threat for severe weather
remains through this time given little in the way of dynamic support.

A drier time frame then returns by Tuesday into midweek as ridging
increases aloft with any isolated PoPs relegated to far north
Georgia through Wednesday. Temperatures will respond in kind with
the warmest days of the week expected Tuesday-Thursday. High
temperatures nudging the 90 degree mark are likely in many areas by
Wednesday. Record highs appear unlikely at this juncture, but values
will still be running some 10 degrees above normal for early May.

The shortwave ridging looks to break down by the end of the week
with additional shortwave disturbances more likely to bring
increasing rain chances again by the end of the period.

.AVIATION...
(12Z TAFS)
Issued at 602 AM EDT Fri May 3 2024

Sct-bkn mid level clouds likely for much of the day, but could go
sct for a brief period this afternoon. There should also be a
decent cu deck between 040-060 for much of today and into the
overnight hours. Models are moving in some MVFR cigs around 12Z
SAT and there is some potential for a brief period of IFR. Not
confident, so will leave the IFR sct. Patchy sprinkles should
may continue through mid morning before a short dry period.
Isold/scat afternoon shra/tsra possible. Winds will be SW during
the day, and SE at night.

//ATL Confidence...12Z Update...
Med confidence all elements.
