.DISCUSSION...
Issued at 145 AM MDT Thu Jul 9 2026

Cool front/dry line arrives today. Still debatable if enough 
dry air works into the region before convection fires off. The 
NAM, GFS and HREF keeps things pretty dry, but the HRRR 
continues to fire off showers and thunderstorms around Arco and 
propagates them east to near IF and Rexburg by 00z. Decided to 
add a slight chance for storms in that area, but its likely that
if we see anything it will probably be just virga. With that 
said, we could still see some descent wind gusts from the virga 
showers if they develop. 

Dry weather is likely into early next week. Hot conditions arrive 
over the weekend. Heat risk values are strongly pinging some form of 
heat products across much of our central and east Idaho and have 
been consistently doing so. Temps in the upper 90s to around 100 
looks very likely for many of our communities. These temperatures 
will flirt with daily records at many sites. Given the consistency 
that we've been seeing will roll with a heat watch for Saturday and 
Sunday. Looks breezy as well over the weekend with wind gusts in the 
20 to 30 mph range for many. This hot weather looks like it will 
continue into Monday, perhaps backing off some on Tuesday. Could see 
the heat products extending into early next week, but with less 
confidence at this time. Potential monsoon flow from the south looks 
to arrive for Wednesday and beyond bringing chances for showers and 
thunderstorms, added cloud cover, and somewhat lower temperatures.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1109 AM MDT Thu Jul 9 2026

Widespread VFR with mainly clear skies through Friday with only
some few to sct mid level clouds. Winds generally under 10 knots
other than some afternoon 10 knots or so at PIH and IDA.

.FIRE WEATHER...
Issued at 145 AM MDT Thu Jul 9 2026

Slight chance of showers and thunderstorms across zone 413 this
afternoon. If storms develop, gusty outflow winds are likely. 
Otherwise very dry weather arrives for the weekend. This will 
allow hot weather to set in and breezy conditions as well. 
Depending upon fuel conditions, could see critical fire weather 
conditions over a large portion of the area.
