.PREV DISCUSSION... /Issued 428 AM EDT Wed Sep 19 2018/

SHORT TERM /Today through Thursday/...

Well above normal temperatures and largely dry conditions will
persist through the short term period. Through the day today a
strengthening upper ridge will build eastward and keep any rain
chances limited south of the area. Under the influence of the upper
ridge, highs were adjusted upward a degree or two above guidance
with low to mid 90s for most areas. These highs are around 10-13
degrees above normal for late September.

The center of the upper ridge will shift overhead by Thursday with
continued well above normal temperatures in the 90s. Rain chances
will remain more or less nil other than perhaps an isolated shower
or storm in the far southwest CWA or the northeast mountains. Though
temperatures are hot, record highs remain near 100 to the low 100s,
so new records are not expected.

LONG TERM /Thursday Night through Tuesday/...

The upper ridge should dominate the regime for a mostly dry end of
the week, then we should see some gradual moisture return from the
west/north as the ridge dampens and moves farther east. Have
slight to low end chance pops for the weekend with the greatest
chance in the north near the more enhanced moisture axis. A weak
low pushing NW across the eastern Gulf should phase with some
upper shortwave energy that gains amplitude across the western
MS/TN valleys by early next week. This should allow for more
widespread shower/storm chances and have included 40-50 percent
pops. Kept temps a degree or two above guidance for the period
through the weekend given recent trends being abnormally high
against climo.
