We begin to enter an active stretch of weather Thursday with increasing clouds, gusty winds, and warming temperatures. Today’s highs will jump well into the 50s with winds gusting from 20 to 35 mph. A few rain showers are possible by evening with showers and a few spot storms likely tonight. Temperatures will remain nearly steady tonight in the 50s.
Friday will be cloudy and mild with scattered showers and temperatures warming into the 60s. Friday night brings a high risk of heavy rain and flash flooding with a slow-moving band of rain and storms.
The heavy rain moves east Saturday morning and colder air sweeps in leading to some wet snow potential Saturday afternoon.
