More CTP thoughts on the Tuesday snow chance for some of us.
Short wave trof is forecast to round the base of the western
upper trof and trek across the srn border of the CONUS, pass
along the GOMEX coast and lift into the middle atlantic region
by the middle of next week/end of the long term period. A
blocking high over New England should provide the cold air for
potential wintry precip over part of central Pa, as this feature
lifts through late Tuesday into early Wed. Continued to bump up
POPs for midweek with this system with rain over the southeast,
a mix of rain/snow over central PA and the best chance for all
snow over the northwest.
