.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1122 AM MDT Tue Jul 1 2025

Weak feature rotating north through East Idaho looks to be able to
provide enough spark to help develop mainly ISOLD TS across the
region. Maintained PROB30 for this aftn/early eve for most terminals
except SUN. Also maintained wind gust potential with VRB G30kts but
latest HRRR indicates gusts could go higher to around 45kts.
Convection expected to diminish prior to sunset, but could still see
localized virga-related gusts continuing to around 06Z. A repeat is
expected after 18Z Wed.

.FIRE WEATHER...
Issued at 1243 PM MDT Tue Jul 1 2025

Today still holds as being the warmest and driest day of the week.
Moisture has already begun to shift into East Idaho, and isolated
thunderstorms are forecast mainly across higher elevations. Gusty
winds in excess of 40 mph will be possible. A repeat is forecast
through the remainder of the week, albeit slightly cooler and
slightly more humid with a slight increase in thunderstorm coverage
each day. Friday looks to the coolest and most humid with scattered
thunderstorms across all districts. Starting today most
thunderstorms are expected to be dry, though one or two may be able
to produce a wetting rain. By Friday, most thunderstorms should be
able to produce a wetting rain. The bulk of the moisture shifts east
for the weekend, allowing for a warming trend to return to East
Idaho. Humidities should return toward more seasonable levels, but
isolated thunderstorms may continue across higher terrain zones
through Sunday.
