We had a few sprinkles early this morning, but we are now drying out behind the cold front that brought heavy rain Monday evening.

Highs today will be slightly below normal, only in the mid-50s, and we stay mostly cloudy. It'll be a bit windy this evening, overnight and early Wednesday morning with gusts around 25 mph.

The coldest day of the week will be Wednesday with highs only in the low to mid-40s. In the morning and afternoon, north of I-80 could see a flurry.

There will be plenty of sunshine during the week, but frosty mornings Thursday and Friday. Frost advisories and freeze warnings are possible at the start of the weekend. If you have temperature-sensitive plants, you will want to cover them with a cloth or bring them inside to prevent being damaged or killed by the cold.

We warm back up near normal just in time for the weekend with sunshine. A few rain showers are possible Sunday.
