FORECAST:

An upper level low on the North coast will bring cloudy, cool, showery conditions to the area in a West-Southwest flow aloft. The freezing level today will start in the 2100 meter range rising to 2400 meters with day time heating. We may see the FL as low as 1800 meters by Thursday.  Yes, early snow flurries in the upper elevations.  The low will slowly drift down the coast leaving an upper level trough in the area for the remainder of the week. Monday and Tuesday look to have heavier showers then the rest of the week. Unsettled--Wednesday and Thursday, looking like a dry Friday with unsettled weather Saturday but models are inconsistent that far out. Possible drying trend on Saturday/ Sunday as a weak upper ridge has a chance of developing. Feels like fall is here!!
