Tracking frost and potential first freeze of the season this week

TONIGHT: Mostly clear and chilly with lows in the upper 30s to around 40.

TOMORROW: Mostly sunny and cool with highs in the upper 50s to low 60s.

EXTENDED: Our coolest week of the season is ahead as temperatures will be below average until the end of the week. High pressure at the surface will pull in cool northerly winds, allowing temperatures to drop about 10 degrees below average by Monday. As winds die down by mid-week, temperatures will fall into the 30s on Tuesday and Wednesday nights. A freeze is expected on Tuesday night with lows near the freezing mark, with widespread frost expected on Wednesday morning. From there, we gradually warm back into the upper 60s by Thursday. We'll end the week slightly warmer in the lower 70s with a disturbance that could potentially bring at least some light rain by next Saturday.
