DISCUSSION

Issued at 1220 AM MDT Tue Apr 7 2026

Today through Thu night...Incoming cold front has trended MUCH lower in the moisture department, and so the risk of thunderstorms and showers is very low now for today and this evening. However, the wind is still expected starting this afternoon and continuing into the evening, so the Wind Advisory will continue.

Temperatures will start cooling today, mainly in the western half of the forecast area, with all locations cooling down for the high on Wed. The trend reverses on Thu, with westerly to southerly flow returning, in spite of some clouds and a chance of precipitation and even some thunderstorms.

Fri through Mon...Cluster analysis was not available this overnight, save for Fri afternoon. The previously forecasted split appears to not happen for Fri anymore. Now the closed CA low gets steered into western NV by a deeper low off the OR coast. This will bring moisture into southern Idaho and a threat of precipitation for Fri, Sat, and Sun as the northern low digs south to the CA coast, then moves inland for the best chance of precipitation on Sun. This wetter scenario has brought temperatures back down, and by Tue highs may only reach the middle to upper 50s for the Snake River plain, rather than continuing to reach 62 deg F or more each day.

The forecasted wind is curious, in that there is little to no support in the upper levels for even a moderate wind, but wind appears to be elevated through this period, on the order of 15 to 30 mph with higher gusts, and not limited to the afternoons.

This extended period has gone through such a radical change, would not trust this current forecast until the solutions settle down.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 511 AM MDT Tue Apr 7 2026

Incoming front is not packing much in the way of moisture; only KDIJ develops any kind of CIG, around 7000ft AGL as the front passes. It also has the only risk of precipitation. The other airdromes are most SKC or FEW in cloud cover. No impact to VSBY expected, unless some dust crops up in the very strong wind.

KSUN is the one most sheltered, but winds get gusty there once the wind direction aligns with the Wood River canyon. Front passage should be in the late morning, with G25KT expected. KDIJ is the last to be affected, and it too has some sheltering. G25KT expected here as well from the west southwest. KBYI also appears to only get to G25KT, due to the strongest wind being farther north; again better when it comes from the west by mid- day. Finally, the most affected are KIDA and KPIH, both peaking in the mid-afternoon at G35KT, from the west southwest and west, respectively.
