- Cooler conditions most of next week with the potential for rain and high mountain snow

DISCUSSION

Issued at 241 AM MDT Sat Mar 28 2026

Near record highs remain likely through the weekend as highs for the Snake River Plain and Magic Valley are expected to be in the low 70s. Still looking at dry weather into Monday when a cold front arrives in the afternoon. Winds will gradually pick up everyday until then with gusts of 20 to 25 likely late this afternoon. On Sunday, there is a 60% chance that gusts could reach advisory levels across the Arco Desert, through INL, and north of Idaho Falls. On Monday, wind advisory level winds are likely (better than 50% chance) north of Blackfoot. As the front moves through Monday afternoon, models continue to dry out and it seems as though we'll see a line of isolated to scattered showers with potentially enough instability for isolated thunderstorms.

The models seem consistent that Tuesday looks like a relatively dry day with our area in between systems, and the NBM is starting to lower the precipitation chances during that time. The models still show Wednesday and beyond looking unsettled and cooler as an upper trough passes through the area. But the details of how that happens are still very much in doubt at this point.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 241 AM MDT Sat Mar 28 2026

A mix of mid to high level clouds will pass through today. Winds will become gusty by afternoon with gusts of 20 to 25 kts likely at most TAF sites. SUN will likely switch to upvalley around 18z and think the winds may be strong enough for it to switch to a westerly crosswind later in the afternoon.
