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

to increase to 10 to 20 mph after midnight across the north central.

.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.


.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1117 AM CST Wed Nov 15 2017

High pressure over the Great Plains will continue to provide fair
