.SHORT TERM...(Today through Wednesday)
Issued at 305 AM CDT Mon Mar 19 2018

Although Spring begins on Tuesday, it sure won`t feel like it in
this area.

Wet and dreary weather will hang on across the area for the next
couple of days before warmer temperatures and a bit more sun
arrive on Wednesday. Temperatures and extent and type of precip
will be the main forecast concerns during this period.

Upper circulation along the KS/OK border at 07Z will make steady
progress east today and reach eastern Missouri by mid afternoon.
This system will drag the bulk of the moisture with it but several
additional short waves over the northern plains will drop
southeast tonight into Tuesday providing the area with colder
temperatures and the chance of more light rain or snow. Periods of
light rain are expected to continue through the day for most of
the area although extreme eastern Nebraska and southwest Iowa will
see some drying develop during the morning as easterly winds allow
drier air over Iowa to reach the Nebraska border. By tonight
however those upstream short wave troughs will begin to impact
the area as they move into the lower Missouri Valley.

Rain will overspread eastern areas by the evening with a mix or
rain and snow spreading into northeast Nebraska. The rain snow mix
will spread east overnight with snow becoming predominate in
northeast Nebraska after midnight with the snow spreading across
the rest of the area through early morning. Accumulations of 1 to
2 inches are possible in northern parts of the area where colder
temperatures will be in place the longest. An inch or less is
possible elsewhere where colder air will arrive later with temperatures
more borderline through the early part of the morning. Lingering
light rain or snow may extend into the afternoon for eastern areas
but little additional snow accumulation is expected due to warmer

Tha last of the disturbances moves out of the area Tuesday night
and after a rather cold morning on Wednesday, temperatures are
forecast to climb into the 50s during the afternoon, much more

.LONG TERM...(Wednesday night through Sunday)
Issued at 305 AM CDT Mon Mar 19 2018

Warmer temperatures are expected for the middle part of the week
into the weekend, but the pattern looks to remain wet. The chance
of showers and thunderstorms will return by Thursday night and
continue into the weekend. Model solutions show little agreement
however by Saturday and Sunday so forecast confidence will be on
the low side during this time period.


.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 614 PM CDT Sun Mar 18 2018

MVFR conditions at all TAF sites, but becoming IFR through the
night, and possibly LIFR at KOFK. A few showers affect the TAF
sites in the first half of the TAF period, and it could mix with
snow at KOFK 09-12z. Beyond then, dry easterly flow may limit
areal precipitation coverage, and opted to leave out of the TAFs
at this time.
