.SHORT TERM...(Tonight through Tuesday)
Issued at 245 PM CST Sat Nov 18 2017

Forecast concerns in the short term will be diminishing

The storm system that affected the local area with a trace to half
an inch of rain (NWS Valley/0.07 OFK/.23 OMA/.06 LNK) has quickly
moved off to the east. Despite gusty northwest winds...sunshine
has helped boost readings into the 40s and lower 50s.

Tonight...the winds aloft will gradually decrease. Northwest
surface winds 10 to 15kts should quickly drop to 10kts or less
within an hour or so after sunset. Some patchy mid clouds with
weak h7 warm air advection is possible tonight. Another patch of
clouds should mailly skirt the area to the northeast Sunday. The
low level flow will become more southwest.

A weak shortwave in the flow aloft should bring thickening clouds
Sunday night and Monday and if thick enough could adversely
affect high temperatures. Highs Sunday should be in the 50s.
Expect highs in the 50s and 60s for Monday with enough sunshine
and southwest flow ahead of the front that arrives Monday night.
The front moves through dry, although look for increased clouds.
Brisk northwest winds should hold temperatures down into the
30s/40s for highs Tuesday.
