.SHORT TERM /Today through Tuesday/...
A weak upper level wave should cross GA today. Moisture with this
feature looks limited...but a couple of the high resolution models
are showing a few showers/thunderstorms this morning mainly north
and west. Previous forecast had low chance pops for a portion of
north and west through about 18z. Have no real reason to make a big
change so have kept a slight chance for the same area through the
morning. Otherwise high pressure will be building aloft across the
southeast through the short term. Rising heights will push
temperatures above normal through the period for most of north and
central GA.

.LONG TERM /Tuesday Night through Sunday/...
An early season heat wave will be building through this week into
the Memorial Day weekend as a strong upper ridge anchors over the
Southeast. By the Thursday into Friday both the ECMWF and GFS
forecast 500 mb heights around 594-595 dam. These heights would be
record levels for the dates based on sounding climatology at FFC,
and in fact would be on par with all-time records for the month of
May.
All of this is to say that temperatures will run well above
normal through the week. While temperatures will already be hot by
midweek with widespread low-to-mid 90s across the CWA, temperatures
will continue to ratchet up through Memorial Day. By Friday into the
weekend, widespread mid-to-upper 90s can be expected, and some 100-
degree temperatures become increasingly likely across at least
portions of central Georgia. Daily high temperature records
appear to be in jeopardy during this time frame. Refer to the
climate section below for daily record temperature information
through the week.
Given this strong upper ridge, precipitation opportunities will be
more or less nonexistent with only an isolated shower or storm
possible in the northeast Georgia mountains on Thursday.
