A weak shortwave will swing through the state on Thursday, bringing low-end chances for precipitation across the higher terrain Thursday evening through early Friday. High resolution models feature some very light precipitation across the central and eastern mountains with National Blend PoPs up to around 25 percent.

Daytime temperatures will remain very stable through late week with widespread highs ranging the 40s.
