.SHORT TERM...(Today and tonight)
Issued at 205 AM CDT Tue Mar 20 2018

A storm system will makes it way to the east today but lingering
clouds and cooler temperatures will follow in its wake. Some
light rain and drizzle will persist into the morning across
southern Missouri. Highs today will remain in the 40s at most

Clouds will linger tonight as disturbances track southeastward
through a northwesterly flow aloft.

.LONG TERM...(Wednesday through Monday)
Issued at 205 AM CDT Tue Mar 20 2018

Improving weather conditions will begin Wednesday as surface high
pressure builds into the region.

A warming trend will begin in Earnest Thursday into Friday as
southerly winds return and upper level ridge expands eastward.
Highs will climb back into the 60s Thursday and Friday with 70s
possible Saturday. This southerly flow will also result in
increasing moisture by the end of the week.

The increasing moisture levels will interact with a low pressure
system that will track from the Plains into the Midwest later
Friday into Saturday to bring at least a chance of showers. The
greater chances look to be east of the Ozarks. The unsettled
pattern looks to continue Sunday and Monday as an upper level
trough transitions eastward from the Rockies. The details on the
evolution of this system remain uncertain but expect at least a
chance of showers and perhaps some thunder this weekend.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1138 AM CDT Tue Mar 20 2018

Deep surface low has moved eastward into the TN Valley region
with an elongated north to south surface ridge over the Plains.
Much of the low level cloudiness was scattering out late this
morning with BBG finally improving to VFR conditions. Northwest
flow upper level disturbances will bring more low-mid level
cloudiness southeastward into the taf sites later this afternoon
and this evening, but it appears that it will remain VFR, and it
also appears that any measurable rain that could produce
visibility reductions will likely remain north of the taf sites.
Gusty northwest surface winds will weaken this evening as the
surface pressure gradient relaxes.
