High pressure ridge is slowly building during the week. It is slowed due to a weak trough moving down the east side through central Montana and Wyoming, which will bring some cloudiness to the northeast corner of the forecast area, and it also keeps the northerly flow over much of central and eastern Idaho. This northerly air flow finally ends Tue, and afternoon highs will spike up to above normal starting Wed, when they will be some 8 to 12 deg F above normal. The chilly overnight temperatures will also warm and be closer to normal for this time of year by Wed night. Skies are nearly clear with no precipitation expected during the period. No significant wind expected during this time. .LONG TERM...Thu through Sun night. High pressure continues to build to summer time levels, but don't expect summertime temperatures.
