Previous discussion...
short term...today through Sunday...temperatures will be 5-10
degrees below normal today in the wake of yesterday's cold front.
As our upper level flow changes from west today to northwest
tonight and then to southwest Sunday, warmer air will start to
move back into the region. Highs Sunday will be near normal. No
precipitation is in the forecast. Winds are expected to be breezy
from around Mountain Home east through the western Magic Valley
this afternoon, but otherwise will be typical for this time of
year.

Long term...Sunday night through Friday...mostly zonal flow over
the Pacific northwest at least through Wednesday which will keep
temperatures around the upper 90s. High pressure over The Four
Corners region will begin to build northward along the Sierra
Nevada mountains on Thursday. Temperatures will slowly increase
next weekend as a thermal low develops over southwest Idaho.
Temperatures will exceed 100 f degrees by Friday and could reach
102-106 f degrees in the lower valleys by Saturday depending on
the location of the thermal low. No chance for precipitation
through Saturday.
