FORECAST:

A weak upper level ridge will bring mostly sunny skies for today in a Northerly flow aloft. We can expect slightly warmer temperatures for today into Saturday, but with this northerly flow we can expect to see some clouds push through and unsettled weather for Saturday afternoon into Monday. The ridge should slowly rebuild for Tuesday and strengthen by Wednesday into Thursday.


    High to the Northwest, low to the Southeast.

    Flow for today.

    Friday at noon.


    Flow for the next few days.

    Clouds will push in from the North for Saturday.

    Another battle of the High and Low.

    Unsettled for Monday, but likely a warm front will push through.

    High has some influence on Monday.

Monday September 25, 2017 Update:

Low is pushing a warm front through the area today with light precipitation in a Northwest flow aloft. The ridge will push back Tuesday and strengthen Wednesday and Thursday for mostly sunny warm weather. The low will send some weak frontal bands through Friday into the weekend with unsettled fall weather.

    Warm frontal band for today.

    Light spotty precipitation.

    High rebuilds Tuesday and slowly shifts East by Friday.

   Weak Front slides in on Friday.
