.SHORT TERM...(This evening through Tuesday)
Issued at 336 PM CDT Mon Oct 16 2017

Relatively quiet weather pattern with the main upper level jet
concentrated to the north along the US/Canadian border.  Weak short
wave will pass through the region tonight, but with very limited
moisture in the atmosphere, will mainly just see a few clouds as it
passes.

Breezy southwest flow is expected to develop across the plains
extending from the southwestern US into the Upper Midwest ahead of a
cold front moving through the region tonight. The front is
relatively weak, with little temperature difference in the new
airmass.

Very pleasant fall day across the region on Tuesday.  Light westerly
flow is expected to transition to the southwest as leeward
cyclogenesis occurs in central Alberta.  Surface ridge across
central and eastern Texas remains in place keeping moisture flow
limited across the region.  With dry atmosphere, have raised highs
in desert type environment.

.LONG TERM...(Tuesday night through Monday)
Issued at 336 PM CDT Mon Oct 16 2017

Pleasant conditions continue into Wednesday with surface high
pressure building into the Central Plains.  As upper ridge focuses
across the eastern half of the country, southerly flow develops
across the plains originating in the Gulf.  This southerly flow will
draw mild temperature north, and moisture most notably on Friday
into the weekend.  This is in advance of an intensifying wave passing
through on Saturday night into Sunday morning. This will result in
showers and isolated thunderstorms across the area. Cooler air
follows behind the cold front on Sunday into Monday.
