SYNOPSIS

21/1251 PM.

Unsettled weather will continue through this evening before the departing low pressure system allows some warming through Friday. Gusty northwest to north winds are possible in the storms wake, especially for Wednesday afternoon to evening. A weak storm with light rain is possible sometime this weekend.

LONG TERM (SAT-TUE)

21/1252 PM.

Another storm system is likely to impact the area that will lead to a cooling trend over the weekend, dropping temperature back into the 60s. There is a 30-50 percent chance of mainly light rain focused across the foothills to interior sometime this weekend thanks to moist upslope flow over the mountains and limited instability. The storm energy is coming from the southwest to west and is weak so significant wind concerns are unlikely, but it does lend itself to below normal forecast confidence. Rain chances and unsettled weather may continue through the end of the month.
