The coldest temperatures of the fall season so far are expected Monday night and Tuesday across Southwest Washington and Northwest Oregon, with freezing temperatures expected at many locations. This will be the first time that many locations will fall to 32 degrees this fall.

A colder low-pressure system moved through Southwest Washington and Northwest Oregon Sunday, and has left a cooler air mass over the area in its wake. Cool brisk east to northeast winds will develop Monday and lead to a blustery day. The winds will decrease Monday night, setting the stage for the coldest night so far this fall season tonight and Tuesday morning. Inland valleys will likely see temperatures between 30 and 35 degrees early Tuesday morning.

The coast will see areas fall close to the freezing mark. The Cascades will see widespread temperatures in the 20s, with colder higher elevation valleys possibly falling close to or even below 20 degrees.

Be sure to take any precautions necessary to protect any remaining tender plants that are still outside. Also consider disconnecting outdoor hoses, and take any other precautions necessary against the cold.
