.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 /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 614 PM MDT Wed May 13 2026

A strong cold front has moved through most of the TAF sites.
There is a slight chance of vicinity thunderstorms for PIH and
DIJ for the next hour. Winds did drop off slightly with the
cold front having moved through. However, strong westerly and
northwesterly winds well behind the cold front are now moving in
from the west. These stronger winds have already moved over SUN
and BYI and winds are starting to drop off from the initial
strong onset for SUN and BYI. These strong winds will move over
PIH in next 30 minutes and move over IDA in the next hour (and
later for DIJ but weakening). Winds will remain elevated for DIJ
as well. CIGS will clear out in the next couple of hours as the
strong westerly and northwesterly winds are also bringing clear
skies. Winds will gradually drop off to 10 to 15 kts after
midnight. Then winds will pick up by mid morning into early
afternoon with gusts of 20 to 25kts for all TAF sites.
