.SYNOPSIS...High pressure will shift east Thursday ahead of the
next Pacific storm, which will stall over the Pacific Northwest
through the end of the week.


.DISCUSSION...Isolated to widely scattered showers and a few
thunderstorms continue over mainly the higher terrain and downwind
valleys this evening. This convection should quickly decrease in
coverage over the next several hours with the loss of daytime
heating. Updated the pop grid for the next few hours to show
isolated showers/tstorms for the downwind valley locations.

A upper level low over the Four Corners region will continue to
pull away from the area this evening. The next upper level low
will dig into the Pacific Northwest Thursday afternoon. The
associated cold front is expected to reach northwest Utah Thursday
afternoon. This should help provide enough lift across northwest
Utah for convective development. Given the very dry subcloud
environment expected ahead of the front, expect any thunderstorms
will be capable of strong winds due to microbursts. Added mention
of gusty winds near thunderstorms to northwest Utah Thursday
afternoon/evening. Otherwise, the current forecast is on track
and no additional updates are anticipated.


.AVIATION...Light and variable winds are expected to shift to the
southeast between 03-04Z. Expect wind gusts to develop between
11-13z Thursday morning and continue through the day.
