KEY MESSAGES

- Dry and mild Sunday, then cooler with increasing winds, clouds and precipitation chances on Monday.

- Gusty afternoon winds in the extended, particularly Tuesday afternoon and Thursday afternoon.

SHORT TERM /Through Monday Night/

The upper ridge will flatten out on Sunday as strong westerly flow pushes in from the Pacific. The area remains on the warm side of the jet which will result in high temperatures reaching well into the 60s across lower elevations, and around 50 degrees in mtn valleys. Winds will become breezy across higher terrain where better vertical mixing is expected. Winds will generally top out between 15-20 mph with gusts to 30 mph in these areas. A cold front will sag south through the area on Monday, bringing a return of clouds and a chance of showers across the mountains. The mountains of Baker County and w-central Idaho will see a 50-80% chance of precipitation Monday/Monday night. The chance for measurable rain/snow drops to 20-40% across the Boise Mountains, and less than 10% across SE Oregon and the Snake River Plain. Increased westerly flow behind the front will bring another round of gusty winds Monday afternoon/evening. Open terrain, including the I-84 corridor will see northwest winds gusting to 35 mph. In this pattern, the wind max aloft will favor the Camas Prairie and northern foothills of the Magic Valley with the strongest winds, where gusts to 45 mph are possible. high temperatures will run about 10 degrees cooler on Monday, or near normal for early March.
