Happy Tuesday, we've got a great day ahead!

Bundle up this morning- Clear skies overnight will allow for strong radiational cooling, with lows dipping to near freezing early this morning. Most areas stay clear, but a little fog could form in sheltered mountain valleys before sunrise.

Treasure Valley Day Planner
A cold morning ahead as temperatures dip near freezing. Bundle up!

A couple of weak systems will brush by Wednesday and Thursday, bringing nothing more than a few passing clouds and occasional gusts through the Snake Plain. Highs stay on the cool side in the mid-50s for valley spots, while mountain areas warm closer to normal under the ridge.

Heading into the weekend, that ridge stays in control before weakening slightly as an atmospheric river clips the Pacific Northwest.

Most of the moisture stays north, but a few mountain showers are possible Friday night into Sunday. Otherwise, expect mostly dry, mild conditions with highs warming 5 to 10 degrees above normal by the weekend and early next week.
