.SHORT TERM /Tonight through Tuesday Night/...
Aside from some fire weather concerns in the near term /see separate
discussion below/...the short term remains quiet and relatively
benign as strong ridging dominates the region. Sfc ridge having
enough of airmass slide east of Cleveland to start building a
classical CAD wedge into the area by Tuesday morning and progged
soundings indicating a shallow layer of decent gradient winds likely
allowing for morning easterly gusts. While resultant temps look
cooler than today...they still remain above normal in the mid 70s
for much of north and east GA. Still dry column with lack of
moisture overrunning so should be mostly clear and precip free.
For temps...given the dry antecedent conditions have gone slightly
warmer than model blend for highs and cooler for lows to widen the
diurnal spectrum and radiational contribution. While the warmer
overnight lows may be east central GA Tuesday AM... they may flirt
with some of the lower temps in the NE mtns Wednesday AM in the mid
.LONG TERM /Wednesday through Monday/...
No changes planned from the previous forecast. Previous long term
LONG TERM /Tuesday Night through Sunday/...
The long term period begins with high pressure remaining in
control of the local area with wedge in place at the surface and
700mb ridge directly over the state. This will promote continued
warm temperatures with values in the mid to upper 70s for the most
Changes are in the offing by the time we get to Thu but
unfortunately...doesnt look at this time like frontal system will
produce consequential rainfall needed to improve conditions. This
looks to be mainly a northern stream system and has difficulty in
tapping into the Gulf moisture needed for substantial rain. As it
stands...models in agreement that we will be lucky to get a tenth
of an inch of precipitation and confined to the northern zones.
A High Fire Danger Statement remains in effect for most of the area
aside from the northern tier of North Georgia into this evening
based on low RH values in the 20-25 percent range. Forecast
humidity should stay closer to 30 percent for Tuesday afternoon and
winds although perhaps gusty in the morning out of the east...should
stay outside critical levels by afternoon. No additional Fire Danger
Statement is anticipated at the moment.
.AVIATION... 12Z Update...
Expect VFR cigs/vsbys through the TAF period. High pressure will
lead to pleasant flying conditions with NW winds around 7-10kts.
Noting high clouds streaming in from the west. This will continue
through the day. A dry cold front will cross this evening/overnight
with winds veering NW to NE between 06-09Z. Anticipate winds to
stay out of the east through much of Tuesday under mainly clear
//ATL Confidence...12Z Update...
Confidence high on all elements.
