High pressure will continue building into the area today and
dominate the region tonight. This will allow cold and dry air to
control the region with afternoon high temperatures in the
generally in the mid 40s. Skies will remain clear tonight with
winds becoming less than 5 mph with sunset. This will result in
excellent radiational cooling conditions with overnight lows in

Upper level patter will remain highly amplified through the end

changes to the long term forecast for Friday and Saturday as

high pressure. Temperatures through the long term will remain
below normal.
