FORECAST:

A weakening low pressure system off the coast continues to send moist frontal bands our way in a Southwesterly flow aloft. The weak upper level ridge will eventually bring unsettled conditions to the area later in the day. Overcast skies with periods of light precipitaion will be around for most of the day with the FL rising to 1400 meters and dropping back to 800 meters this evening. The ridge strengthens on Sunday, but there will be some lingering cloud as well with the FL rising to 1800 meters with daytime warming. A low pressure to the South will bring overcast skies to the area Sunday night with a series of frontal bands heading our way for next week. It truly is the winter that keeps on giving!!
