.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --114 PM Update...Kept clouds in longer across much of the CWA w/the
exception of the downeast and coast as satl imagery showed clouds
beginning to break up in that area. Temps not rising as quickly as
previously forecast for the downeast region. The reason is that
clouds have held on a bit longer. Decided to undercut the
afternoon temps by 2 degrees. No other changes needed attm.
Previous discussion...A surface ridge over NY and PA early this
morning will build into Maine today and will only very slowly
slide east tonight. An occlusion will move into NY State late
tonight. High clouds will increase tonight. In the north, the
challenge will be whether the low clouds hang in or break up. If
they break up temperatures will have the opportunity to drop off
rapidly and could get below zero in the deeper sheltered valleys.
If the clouds hang in, temps will not get nearly as cold.
