.DISCUSSION...I trough extending westward from the Great Lakes
region still has us under a cooler air mass today. However, high
surface pressure east of the Continental Divide is setting up
easterly flow, which flows down off the Continental Divide, into
western Montana and Idaho today. Also, while the upper level
trough remains over our region, it is filling in today as we
transition to a ridge of high pressure for Saturday. That means we
can look forward to a cooler than average day today with a chilly
east wind, but, there will be fewer if any snow showers today.

Temperatures bump up quickly under mostly sunny skies for Saturday
as an upper level ridge takes over, but just for a day. By Sunday
another cold front is coming. This next one won`t be as cold as
the last one though, so we`re expecting showers Sunday and early
next week to mainly be rain in the valleys with mountain snow.

All the long term models and ensembles point to the active, but
not really intense Spring weather pattern to continue for the next
couple of weeks.

.AVIATION...Rising heights today along with some light easterly
downslope flow from the Continental Divide will keep showers at a
minimum today. VFR conditions expected through Saturday as a ridge
builds in.
