.SHORT TERM...(Tonight through Friday)
Issued at 252 PM CDT Tue Sep 25 2018

High pressure building into the region tonight will allow for
clearing skies and diminishing winds. This will result in a chilly
morning with below normal lows in the lower to mid 40s. A couple
of locations could even reach the upper 30s in northeast NE, but
not low enough for any frost concerns yet.

Northwest winds become southwest through the day Thursday. With
abundant sunshine, highs should reach 65 to 70, and overall will
be a pleasant early Fall day. It will not be as cold Wednesday
night with lows a couple of degrees either side of 50.

There is front that will will move through the region on Thursday.
Moisture is initially lacking with the front, thus just expecting
an increase in clouds and a wind shift, but highs should reach 68
to 74.

Moisture does increase behind the front Thursday night, thus a few
showers should move into areas north of I80 by daybreak Friday.
Scattered showers continue through the area on Friday as cooler
temperatures prevail. The ECMWF is not quite as cool as it was
previously, so backed on a little on the cooling, but highs Friday
will only reach 53 to 63 degrees.

.LONG TERM...(Friday night through Tuesday)
Issued at 252 PM CDT Tue Sep 25 2018

Shower chances continue south of I80 Friday night. This will be
the coolest night of the season thus far, with lows in the mid 30s
across northeast NE with areas of frost possible as high pressure
settles overhead.

Both the GFS and Canadian models suggest a quick return flow sets
up on Saturday, with a scattered cold rain showers moving back
across the forecast area, but the ECMWF has remained consistent in
keeping rain to the south. Cool highs again Saturday with readings
again 56 to 63. Shower chances continue into Sunday, but Monday
looks dry, and Tuesday could see showers north of I80.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1119 PM CDT Tue Sep 25 2018

A surface high over the central High Plains will build east-
southeast through the region during the forecast period with light
northwest winds strengthening from the west on Wednesday
afternoon. Expect generally cloud-free skies with no restriction
to visibility.
