After a sunny day today, rain chances increase tomorrow afternoon through Friday. When all is said and done Friday night, anywhere from a half to 1.5 inches of rain could fall.

After the rain moves out Friday evening, a nice weekend is on tap. With highs near 50 Saturday and into the mid 50s Sunday. Rain chances increase again Sunday night and Monday as another area of low pressure moves to our northwest.
