.SHORT TERM...Today through Wed night. High pressure ridge is
slowly building during the week. It is slowed due to a weak trough
moving down the east side through central Montana and Wyoming,
which will bring some cloudiness to the northeast corner of the
forecast area, and it also keeps the northerly flow over much of
central and eastern Idaho. This northerly air flow finally ends
Tue, and afternoon highs will spike up to above normal starting
Wed, when they will be some 8 to 12 deg F above normal. The chilly
overnight temperatures will also warm and be closer to normal for
this time of year by Wed night. Skies are nearly clear with no
precipitation expected during the period. No significant wind
expected during this time.

.LONG TERM...Thu through Sun night. High pressure continues to
build to summer time levels, but don't expect summertime
temperatures. However, the will continue 10 to 14 deg F above
normal with the abundant though time-shortened number of sunshine
hours. Sat should be the warmest period with highs in Pocatello
in the 70 degree range, and overnight lows continuing near normal,
which is near freezing. No significant wind during this time.


.AVIATION...VFR conditions will prevail throughout the 
forecast period. Huston


.FIRE WEATHER...A ridge of high pressure positioned along the NW 
coast will expand inland today and Tuesday resulting in a warming 
trend that will continue through the week. There is an outside 
chance that a cut-off low positioned over Arizona will lift north 
through Utah Wednesday resulting in a weak threat of showers over 
the SE mountains Wednesday/Thursday.  Otherwise dry conditions will 
prevail until early next week when a Pacific trough is expected to 
spread inland. Huston
