DISCUSSION

Issued at 210 AM MDT Tue Mar 17 2026

Viewing satellite early this morning shows cloud cover moving eastward out of Idaho as high pressure builds in over the Southwestern US today. A few mid and upper level clouds will hang around today, but expect more sunshine than we saw yesterday. The increased sunshine, breezy west southwest winds gusting around 25-35 mph, and mild morning temperatures in the 30s and 40s set us up well to see highs jump significantly for this afternoon. In fact, many of us will be almost 10 degrees warmer than yesterday, reaching the 60s in the Snake River Plain and low 70s in the eastern Magic Valley. Record highs for today generally range from upper 60s to low 70s, so there is about a 10 to 20 percent chance of Burley, Pocatello, and Idaho Falls tying/breaking records this afternoon. It seems much more likely, and is looking like a done deal really, to break records tomorrow, Thursday, and Friday as afternoon highs warm into the mid and upper 70s. On Friday, there is a 40 percent, 90 percent, and 95 percent chance of Idaho Falls, Pocatello, and Burley (respectively) reaching 80 degrees which would set all-time record highs for the month of March at all three locations. One thing to keep in mind with these warming temperatures, breezy afternoons, and dry conditions is that we will see the increasing potential for brush fires as vegetation has yet to totally green up give that it is only mid March. And it looks like we'll be dry for a bit as there are no real precipitation chances until the weekend and even then it looks limited to the higher mountain elevations.
