.DISCUSSION...

Today through Tonight: Latest Rap and Satellite imagery showed
an upper trough over the Mississippi Valley with a cold front
moving through the region. The front was able to push any showers
associated with a disturbance in the gulf to the south. Predawn
readings were in the 30s and 40s.

For today expect some breezy northerly winds in the wake of the
front especially in the delta region. Under full insolation it will
be another cool day with below normal readings with highs in the
middle 50s northwest to around 60 southeast. For tonight expect the
winds to taper off as high pressure builds into the region from the
northwest as the upper trough persist across the region. Under clear
skies and light north winds radiational cooling will provide lows
from the middle 20s to the lower 30s./17/

Thanksgiving Day through mid week next week:

Cool, dry air will continue to filter into the ArkLaMiss on
Thanksgiving Day resulting in a clear, cool holiday. Expect highs
to range from the upper 50s to near 60 and lows on Friday morning
falling to near or below freezing for a good portion of the
region with better chances in the Northeastern counties of our
region. A stagnant upper ridge centered over the Baja Peninsula
will result in persistent upper NW flow over the region through
early next week. Pwats on Thursday will fall below 0.25" but
moisture will begin to increase by the weekend ahead of a surface
front that will extend from southern Canada to the Gulf Coast,
traversing through the ArkLaMiss on Saturday. No precip is
expected along this front and only an increase in cloudiness is
expected. Dry air will once again filter into the region behind
this frontal passage. The weather pattern will begin to modify
early next week as the upper ridge to the west finally starts to
shift east, resulting in increasing upper heights over the region.
Low level southerly flow will gradually begin to increase on
Monday as a surface high moves east of the area resulting in
return flow from the Gulf of Mexico. Temperatures should reach
well above their average late November values by Tuesday before a
front approaches the region on Wednesday, bringing our only
chances of rain over the next 7 days.

.AVIATION...
06Z TAF discussion:
VFR conditions are expected to continue. A cold front will push
through the region and bring northerly winds back to the forecast
area around 10kts, with some locations seeing gusts of 15-20kts by
later this morning into during the day. Winds will taper off by
this evening as the front moves off to the southeast./17/
