Dry weekend expected with warmer temperatures…. cold front arrives Tuesday with rain, trough follows behind it…

High pressure maintains Saturday and Sunday with a warm weekend expected. Highs are expected to reach the middle to upper 70s both days, with the warmer of the two days being Saturday, under partly to mostly sunny skies.

Monday will see more clouds than sun with a system to our west and a warm front in the vicinity, but no rain is expected. A slow moving cold front with possible low pressure enhancement of rainfall will move in Tuesday, with periods of rain likely along and ahead of that boundary. That rain tapers to showers and ends overnight Tuesday night. Wednesday we begin to dry out once again and turning sharply cooler as a deep trough settles in for several days. We will feel the full effects of that trough by Thursday under partly cloudy skies, and then winds turn to the WSW on Friday, and temperatures moderate somewhat as the trough begins to lift out.
