At 09z...Surface high pressure extended from Montana southeast

40 degrees most areas of western Nebraska.

&&

.SHORT TERM...(Today and tonight)
Issued at 337 AM CST Wed Nov 15 2017

A progressive upper trough currently moving into Minnesota and the
mid Missouri Valley will move into the Great Lakes and Ohio Valley.
Surface high pressure will slide east across the Northern And
Central Plains today. This will bring a return of light southerly
winds to the western zones by this afternoon, while northwest winds
of 10 to 20 mph in the east diminish this afternoon. A cooler
airmass with h85 temps holding near 0C at O`Neill while warming to
5C n the far western zones. Went slightly cooler than previous
forecast across the northeast, where highs from 45 to 48 forecast.
Lows 50s expected central and southwest areas. Skies mainly sunny
today with just some scattered high cloud to move in later today.

For tonight, increasing mid and high clouds increase along the cusp
of the upper ridge axis, especially north central. Southerly winds
to increase to 10 to 20 mph after midnight across the north central.
Lows remain very near previous lows from the upper 20s to lower 30s.
Better mixing across Sheridan and Cherry county to keep temperatures
there in the lower to mid 30s most of the night.

.LONG TERM...(Thursday through Tuesday)
Issued at 337 AM CST Wed Nov 15 2017

Shortwave trough will be digging into the Pacific northwest
Thursday. The system will move east/southeast and cross the central
and northern plains Friday night into Saturday. Ahead of the system
Thursday, south winds will increase due to falling pressure and a
tightening gradient. Continued breezy from the south Thursday night,
then as the front crosses the area Friday winds switch to the
northwest and will continue to be breezy into Saturday. Wind will be
the main story with this system, but increasing mid level
frontogenesis should lead to a band of light rain and light snow
Friday night. This quickly ends Saturday as dry air aloft and
sunshine take hold, with conditions lasting into Sunday. Temperature
wise, very mild Thursday and Friday with highs in the mid 50s to mid
60s. Then cooler behind the front Saturday with mid to upper 40s. A
more westerly downslope wind develops Sunday, with highs back into
the 50s.

Dry and mild weather continues next week. Highs Monday should again
be in the 50s, but somewhat cooler by midweek as a backdoor cold
front lowers highs into the mid and upper 40s.
