Area Forecast Discussion

.SHORT TERM...Tonight through Tuesday

Dry air mass remains in place tonight with low dewpoints and
clear skies leading to efficient radiative cooling. Additionally,
with surface high pressure located over the southern Appalachians,
expect cold air drainage to result in the usual cooler
temperatures along the Pearl and Pascagoula Rivers. Am carrying
mid 30s along the two drainages, with generally upper 30s
elsewhere along/north of the I-10/12 corridor and low to mid 40s
south of the interstate.

High pressure shifts eastward Monday, with surface winds turning
more southeasterly, and resulting in gradual warming and
moistening trend through Tuesday. While lows on Tuesday will still
be near or slightly below normal, expect afternoon highs to be
about 5 degrees above normal.

.LONG TERM...Wednesday through Saturday

Warming trend continues through midweek as upper ridging
establishes itself over the southeastern US. By Wednesday,
afternoon temperatures will be well above normal. By late in the
week both morning lows and afternoon highs will be about 10
degrees above normal. Thursday looks to be the warmest day, with
afternoon highs topping out around or just over 80 degrees most
places. The one exception will be the MS Coast where cool shelf
waters and onshore winds could mitigate warming.

Ridging remains in control of the area weather through at least
Friday. Going into the weekend, model spread begins to increase
substantially concerning an upper low and associated surface
frontal system moving out of the Four Corners area and into the
Mississippi Valley. Still plenty of time to iron out the details
on that system with no appreciable rain chances before at least
Saturday.

.AVIATION...
Valid through 06z Tuesday...
Basically a wind forecast as no ceiling or visibility
restrictions are expected. Winds will begin to ease by late
afternoon with light to calm winds expected to persist through the
night. Expect winds to pick up again after sunrise Monday with
southeasterly winds of 7-12kts by midday. After sunset Tuesday,
winds will once again calm to 5kts or less.

&&

.MARINE...
The gradient between high pressure to the east and a series of low
pressure systems passing from the four corners region to the Great
Lakes will maintain a persistent moderate east to southeasterly
flow over the coastal waters. Exercise caution headlines look to
be needed across portions of the open waters during several
forecast periods. The current headline has been extended through
tonight for the outer waters. No appreciable rain chances through
the end of the work week, but another front could bring more
active weather to the waters next weekend.
