.SHORT TERM...(This Evening through Wednesday)
Issued at 249 PM CDT Tue Mar 20 2018

Temperatures are the main issue for the next couple periods. For tnt
expect plentiful cloudiness across the region, especially the
eastern CWA and thus low temps should remain fairly mild. A weak
wave does move through the northeast CWA, but soundings only portray
decent llm/saturation and no ice introduction aloft, thus about all
that can be expected overnight is fg/dz/fzdz. Wednesday should be
dry with some reduction in clouds, and thus warmer temperatures. The
expected LL WAA should provide for a few degrees jump over today`s
temps. Winds will also increase some for Wednesday as low pressure
begins to develop over the Rockies.

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 249 PM CDT Tue Mar 20 2018

Models continue to show decent agreement with the band of
precipitation expected to move through the region on Friday. Will
continue with high chances for a rain/snow mix on Friday, with some
brief potential for freezing rain as well in the morning hours.
Overall though, it appears to be mostly a rain event by afternoon as
warmer air spreads over the region throughout the day. Beyond
Friday, the weather pattern still looks to remain generally
unsettled, with more chances for precipitation heading into the
weekend and early next week. Model solutions vary quite a bit more
this far out, so uncertainty increases. Will therefore stick with
low chances at this point until better agreement is reached.

As for temperatures, they look to warm a bit from what we have been
seeing recently. More 40s are expected to move into the region,
which will help with snow melt.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon)
Issued at 1215 PM CDT Tue Mar 20 2018

Clouds are expected to persist through tonight across the region.
Much of it will favor MVFR, but IFR and even an occasional VFR
cig is possible, especially out west. Isolated to sct snow showers
are possible through early evening at all terminals.
