KEY MESSAGES

- Breezy afternoon wind gusts near the Magic Valley Tuesday.

- Record high temperatures Wednesday through Saturday with dry conditions.

SHORT TERM /Through Thursday Night/

An unseasonably strong upper level ridge will continue to strengthen over the southwest United States during the short term. While the most extreme heat will be over the Desert Southwest, this will bring several days of record high temperatures to southeast OR and southwest ID. Temperatures will be 20-25 degrees above normal, with the lowest valleys seeing low to mid 80s and the mountains reaching the 60s over the next several days.

LONG TERM /Friday through Tuesday/

Friday will remain dry and warm with record temperatures (around 20 degrees above normal). Come Saturday, the ridge that dominated the short-term will begin to flatten out. A shortwave grazing our northern zones will support a 20-50% chance of precipitation in the west central ID and Boise Mountain zones Saturday. While uncertainty remains regarding the exact magnitude of a cool down, zonal flow aloft will support cooling temperatures (although still 5-10 degrees above normal) and breezy conditions. Precipitation chances will increase area-wide come Tuesday, as a Gulf of Alaska low begins approaching our area. Snow levels will fluctuate between 5-8.5 kft MSL in the zonal flow, with the lower snow levels north.
