DISCUSSION

Issued at 109 PM MDT Tue Mar 17 2026

No significant impacts for the next week are expected. Will have record or near record warmth Wednesday through Friday with valley highs in the 70s to lower 80s and mountains mainly 60s into the 70s. Will be some breezy afternoons with the strongest 20 to 35 mph in the Snake River Plain. The next slight chance of precipitations will be in the mountains on Saturday and Sunday. We will get a cold frontal passage with about a 10 to 15 degree cooling Saturday into Sunday but temperatures will still be well above seasonal normal with 50s mountains and 60s valleys. By next Tuesday, a chance for more widespread precipitation but very low confidence that far out.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Gusty wind appears to hold off until mid-afternoon when Theta-E profile gets inverted. And gustiness looks considerably less for KSUN and KBYI, where it struggles to get to 20KT above the boundary layer. Clouds will eventually clear out, with even KDIJ clearing by 18/09Z tonight; everyone else is sooner.

Wind gets super light during the late night hours, although KPIH appears to have a consistent northeast drainage wind. KDIJ appears to have enough in the boundary layer to keep elevated tonight at around 10KT, mostly from the south. Looks like little chance for wind at KSUN to have a southerly component, the flow aloft is northwesterly and it overwhelms any slope-valley interaction with some 20KT in the boundary layer from that direction. However, not a whole lot of cloud cover and would not be surprised to see a shift to southeast if it takes a while for the morning inversion to break. The theta-e profile inverts by 17/20Z, so I have hope.
