Temperatures will remain above normal Tonight. .Short Term.../Sunday through Wednesday/... The cold front is expected to move southeast across the region during the day Sunday. Scattered showers will accompany the frontal passage, and noticeably cooler air will arrive following passage. Due to the enhanced pressure gradient, winds will become gusty behind the front.

Strong high pressure will build from the northwest Monday through Monday night, then to the north Tuesday through Wednesday. This will be a cooler than normal period, with freezes inland Monday night and Tuesday night. As the high moves more to the north by Wednesday, the flow will become more onshore with the potential for a coastal trough developing, with a few coastal showers becoming possible. .Long Term.../Wednesday night through Saturday/...
