SHORT TERM /Tonight through Monday Night/...
Tropical Depression Bonnie is now inland, just northwest of
Charleston SC. Light rain and associated cirrus shield has eroded
across east-central GA this afternoon, but has left a fairly well-
defined north-south oriented differential heating zone across the
area. Within this zone...low level convergence helping to generate
and support scattered showers, especially between Covington and
Macon. Expect this to continue through the afternoon with ongoing
surface heating. Not expecting any major impacts with convection
aside from occasional cloud to ground lightning, locally heavy
rain, and brief wind gusts to 35 mph.
Tonight...Loss of heating should taper any convection across the
area as TD Bonnie meanders north/east, just inland along the SC
coast. Temps will gradually cool back into the 70s this evening with
overnight lows similar to this morning /generally in the 60s/.
Memorial Day...the area remains sandwiched between "Bonnie" and a
weak upr ridge extending from the Lower MS Valley to the Ohio
Valley. Daytime heating and weak energy rotating south/west from
the upr low associated with Bonnie could spark a few afternoon
showers/storms, but most areas will remain dry and warm. Abundant
sunshine expected for the first part of the day will allow temps
to warm quickly into the lwr-mid 80s by midday.
LONG TERM /Tuesday through Sunday/...
Extended forecast trends look good with best rain chances Friday and
through the weekend. Have made minor adjustments to late extended
QPF (Day 7) to account for latest model trends. Have also gone ahead
and drawn far north Georgia in the likely pop region for Friday
afternoon which now has better neighbor consistency. Model
uncertainty for Day 6 (Friday) is relatively low, and confidence is
fairly high likely pops are necessary for the pattern. Otherwise
only small adjustments were made to temperatures and dew points.
Mainly VFR conditions will prevail this TAF period. There are a
few showers out there right now but they should stay east of the
ATL area TAF sites. winds expected to stay mainly out of the NW
but will see winds turn to the NE briefly between 00z-04z as a few
outflow boundaries move across the ATL area. wind speeds will stay
10kts or less through Mon afternoon. will see wind speeds increase
to 10-14kt between 18z Mon and 00z Tues. No restrictions to VSBYs
//ATL Confidence...00Z Update...
Confidence high on all elements.
