SHORT TERM
Today through Friday night...Rain showers have ended across most of SW Idaho this morning as a weak, shortwave trough exits toward the southeast. Precedent moisture, combined with cooler and calmer conditions this morning, have created mountain-valley fog development across portions of northeast Oregon and w-central Idaho. Breezy winds will continue for the Magic Valley and vicinity through mid-day today due to a persisting surface pressure gradient. Behind the trough, remnants of mid-level moisture and weak instability will help to generate isolated afternoon showers in the central Idaho terrain, but impact is expected to be minimal. Thereafter, a high-amplitude ridge over the eastern Pacific today will move inland by tonight, and center over the forecast area by late Thursday. Strong subsidence from the ridge will bring dry and sunny conditions, with temperatures warming to approximately 5 to 8 degrees above normal on Thursday. Further warming is anticipated Friday as the ridge axis passes to the east of the area and is replaced by prevalent southerly flow aloft.

LONG TERM
Saturday through Wednesday...A large Pacific trough will approach late Friday night and transition to a cut-off low over the weekend. The center of the low is projected to track farther south than previous model runs, and is now expected to move over southern CA/NV. Despite this evolution, rounds of moisture are still forecast to spread into eastern Oregon and southwestern Idaho throughout the weekend, and temperatures will lower to near/slightly below normal. The highest probability of showers and thunderstorms is on Saturday, with precipitation chances reaching 50-80%. Saturday afternoon instability and moisture parameters will be favorable for thunderstorm development, with around a 20% chance of occurring across the forecast area. Activity will decrease in southeast Oregon, but continue in southwest Idaho, for Sunday and Monday as the center of the low moves over Utah/Arizona. Models begin to differ after Monday, but currently favor a drying and warming trend for most areas Tue/Wed.

AVIATION
Low clouds and patchy mtn-valley fog for the southwest ID terrain this morning, causing mountain obscuration. Periods of IFR-LIFR conditions at/near KMYL and near KJER before 30/15Z. Becoming VFR and mostly clear for all areas by late morning. Surface winds: W to N 5-15 kt. Gusts around 20-25 kt for KMUO-KTWF-KJER. Winds aloft at 10kft MSL: NW to N 5-15 kt.

KBOI...FEW-SCT low clouds along Boise foothills through mid- morning, obscuring foothills at times. Otherwise, VFR and mostly clear. Surface winds: W to NW 5-12 kt, occasional afternoon gusts around 20 kt.
