Area Forecast Discussion
National Weather Service Boise ID
1000 AM MDT Tue Jul 2 2024

.DISCUSSION...Near normal temps and mostly clear through
Thursday. Of note, however, are breezy winds Wednesday
afternoon thanks to an enhanced surface gradient as an upper
wave moves east. Gusts in the general range of 30-40 mph will
develop in areas including and east of Mountain Home,
Fairfield, and Twin Falls. Significant warm up coming in the
long term as a ridge builds after the 4th, with multiple
consecutive days of 100 degrees or higher in the Snake Plain. No
precipitation expected through the forecast period.

&&

.AVIATION...Generally VFR. High density altitude will become a
factor by the weekend into much of next week. Surface winds:
variable less than 10 kt overnight becoming N-NW 5-15 kt with gusts
to 20 kt. Winds aloft at 10kft MSL: W-NW 15-25 kt.

KBOI...VFR. Surface winds SW-W less than 4 kt overnight, becoming NW
7-11 kt by Tues./16Z.

.PREV DISCUSSION...
SHORT TERM...Today through Thursday night...Dry northwest flow
will dominate the pattern through Thursday. This will keep
temperatures a couple degrees below normal today and Wednesday,
warming to near normal Thursday as an upper level ridge along
the West Coast starts to expand inland. Skies will remain mostly
sunny with no chance of precipitation. Afternoon winds will be
breezy, strongest on Wednesday as a shortwave trough passes to
our north and enhances the surface pressure gradient. Wind gusts
Wednesday afternoon across the Magic Valley and Camas Prairie
are expected to reach 30-40 mph with gusts of 20-30 mph
elsewhere.

LONG TERM...Friday through Tuesday...Model guidance remains in good
agreement in depicting a strong upper ridge along the west coast on
Friday that gradually builds eastward and reaches our area by early
next week. This will lead to dry and very hot conditions.
Temperatures will likely (greater than a 60 percent chance) exceed
100 degrees in the lower valleys Saturday through Tuesday.
