.DISCUSSION...
Issued at 1031 AM MDT Wed May 13 2026

An active weather day is under way. As low pressure
approaches from the west, we are seeing increasing winds already and
will continue into this evening even behind the front. Outside of
storms, we are expecting gusts in some cases up to 55 mph. With
thunderstorms gusts in excess of 60 mph are likely with gusts over
65 mph possible. Storms should clear by late evening along with
stronger wind subsiding. Otherwise, we remain dry until the weekend.
Today is the last widespread WELL ABOVE AVERAGE temperature day we
will see for a bit. Ahead of the front, especially where downslope
is occurring, we are still looking at potentially hitting 90
degrees. We drop to right around AVERAGE for this part of May,
before dropping BELOW AVERAGE over the weekend and early next week.
Sunday still looks like the coldest day, especially if we can get a
deeper low in place, highs are in the 40s and 50s areawide.
Overnight lows and more frost/freeze issues are expected to return.
We may see some pockets of frost and light freeze until Saturday
morning. Beyond that, several morning of widespread frost and freeze
conditions are likely. Monday and Tuesday mornings will be the
coldest based on the latest trends in the Blend of Models. We are
looking at widespread 20s for overnight lows across portions of the
Snake Plain and Magic Valley, with the more populated cities barely
hitting freezing.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1203 PM MDT Wed May 13 2026

Winds will be the biggest issue over the next few hours across
eastern Idaho as a potent trough moves north of the region.
Gusts around 30 kts are likely. Additionally, this feature
combined with afternoon heating, will support scattered
thunderstorm development over the next few hours. Given the
synoptic setup, these storms are not likely to produce
precipitation but will likely produce gusty outflow winds in
excess of 50-60 kts possible across parts of the region. KPIH,
KIDA and KDIJ have the highest potential for winds like this
with slightly lower probabilities around KSUN and KBYI. After
14/02Z or so, convective potential drops quickly as cooler air
starts to move into the region with an associated cold front.
Skies will clear into the day on Thursday but winds will remain
breezy overnight and throughout much of the day tomorrow, 15-25
kts or so with higher gusts.
