DISCUSSION

The dry and warming pattern will persist through tomorrow as high pressure remains in control over the region. Expect daytime temperatures to warm into the upper 70s to low 80s across low elevations today and tomorrow.

An upper-level trough will work eastward with the accompanying cold front bringing breezy to windy conditions tomorrow. The strongest winds will be across the central mountains and eastern Magic Valley, where gusts will largely range 30 to 40 mph, while gusts will generally range 20 to 30 mph further east. Precipitation will remain further north outside of our CWA. Temperatures will run much cooler behind the front, with highs returning to the 60s and low 70s during the weekend.

The next Pacific trough will move onshore Sunday, bringing isolated showers and thunderstorms to eastern Idaho late Sunday through Monday evening. Expect a 5 to 10 degree cooldown for most locations between Sunday and Monday, sending daytime highs down into the 50s and 60s. Ensembles suggest weak high pressure building in from the west beginning Tuesday, keeping conditions dry and allowing temperatures to very gradually warm through later week. That said, daytime temperatures will still run below average during this timeframe.
