.SHORT TERM...(Today through Tuesday)
Issued at 255 AM MDT Mon Oct 16 2017

A ridge will strengthen over the western U.S. with very dry
conditions and decreasing winds. Winds aloft will be from the
northwest today, gradually shifting to the west by Tue afternoon.
Temperatures, day and night, will rise steadily each day.

.LONG TERM...(Tuesday night through Sunday)
Issued at 255 AM MDT Mon Oct 16 2017

Models remain fairly consistent through the late week period as a
trough moves onto the Left Coast...but have made some changes
going into the weekend. The upcoming week looks dry with the
storm track well to the north...temperatures will be at or above
normal with mainly just some high cloudiness drifting by at
times. This cloud cover with be the thickest on Thursday as the
low level jet lift moisture up from the south. Precipitation is
indicated in some of the models but will have to evaluate the dry
low layers to determine if any of this can get to the grounds.
Friday still appears to be on the windy side as the western trough
moves onshore tightening the Southwest gradient from the Great
Basin to the Great Plains. The main trough will swing through late
Friday through Saturday bringing the next better chance of
precipitation and a shot of cooler air as a cold front is forced
through. The big difference is the closed low out in the E.Pac
which this trough is no longer phasing with. As such this trough
will continue to progress across the central CONUS with a strong
high pressure ridge building in for Sunday.

Issued at 1131 AM MDT Mon Oct 16 2017
