Unsettled weather for today in a Northwest flow aloft. Cool cloudy conditions with the occasional shower. Tuesday will be mostly cloudy but dry with a good chance of a sunny breaks in the afternoon. A weak frontal band pushes through early Wednesday with periods of light precipitation, sunny breaks following the fast exit of the front. Thursday will be dry but cloudy and slightly cooler. Models diverge on the outcome for Friday as there is potential for a vigorous cool low to bring precipitation to the area on Friday. This system will likely exit south quickly with the ridge rebuilding on Saturday, with mostly sunny weather into Sunday. Clouds push back in on Sunday before another weak front on Monday. Guesstimates: Trace-1 mm by Tuesday am, 1-3 mm by Wednesday am, 0 mm by Thursday am, 0-trace by Friday am, 5-10 mm by Saturday am, 0 mm by Sunday am.
