High pressure will be building into the area tonight and tomorrow. This will create gusty winds and deliver chilly temperatures. It will also produce partly to mostly sunny skies tomorrow and Friday. But over the weekend, as the high pressure moves out, we will come under the influence of a large scale region of cool and unstable air. Temperatures will be below average and there will be good chances of rain on Saturday and Sunday and probably into Monday and Tuesday, as well.
