.SHORT TERM...(Today and Tonight)
Issued at 318 AM CDT Sat Apr 21 2018

Overall quiet weather is expected this week. A large cut-off low
pressure system moving through the central Plains will be the main
driver of weather today. This morning`s overcast skies will
continue into the afternoon, with chances for sprinkles or light
rain for the tri-state area. Lift is weak with these showers, and
dry air near the surface will minimize accumulations. By the
evening, drier air moving in aloft will reduce the chance for
sprinkles and begin to break up clouds. Temperature in the upper
40s to low 50s are forecast, with light east winds.


.LONG TERM...(Sunday through Friday)
Issued at 318 AM CDT Sat Apr 21 2018

A warming trend is expected Sunday and especially Monday, as a upper
level ridge to the east and an approaching low allow warmer low-
level southerly flow to reach the region. Highs look to reach into
the 60s on Monday, which will be near normal for this time of year.

A quick moving shortwave trough moves through on Tuesday, bringing
our next chance for light rain. A tightening pressure gradient will
bring cooler, breezy north winds, gusting into the 20 mph range;
nothing out of the ordinary for this time of year, but will likely
be noticeable given the warmth and very light winds over the
preceding days. Temperatures will remain slightly below average
for the second half of the week.
