High pressure is building across Idaho for the weekend, bringing dry air for widespread clear skies and warm temperatures.  Boise's low tonight will be near 58 degrees, with a light northwest breeze.  Mountain areas will drop to the upper 40's.

The spectacular weather will continue tomorrow, with sunshine in the lower valleys - Boise near 87 degrees - but a few afternoon clouds building over the mountains for a few isolated showers. 

Monday and Tuesday remain warm and dry with highs in the upper 80's to near 90 degrees, while afternoon showers and thunderstorms will be widely scattered in the mountains.  A bit breezy each afternoon.  

Dry but cooler conditions develop heading into the last days of Spring, with mostly sunny but breezy weather in Boise.  Highs on Wednesday near 83, cooler on Thursday and Friday near 75 degrees, and staying a few degrees below normal through next weekend, although still dry.  Summer officially begins next Friday.

NOTE:  The KCBX radar site south of Boise is back up and running ahead of schedule!
