High pressure will start building in overnight and cause clouds to decrease. This decrease in cloud cover, along with the colder air from yesterday's cold front, will cause temperatures to drop below freezing tonight.

The weather looks fairly benign through much of the week with the next chance for any significant precipitation on Thursday.
