[su_note note_color=”#ffffff”]Updated Sun 10:34 AM — The newer high resolution models becoming available this morning continues with my forecast update just below.  The somewhat older NAM model just available still shows some convective activity possible in the afternoon—

[/su_note]

Last night’s models have backed away from the heavy rains expected in the Philadelphia area this morning.  However, light intermittent rain will continue through today.   Total QPF predictions of 1 + inches of rain have been reduced down into the 0.3-0.6 range.

High temp 53.0º sd 4.1º. (High spread uncertainty)

Additionally, there had been expected to be some convective activity (thunderstorms) in the late afternoon.  That activity is now predicted to be diminished and, if it occurs, will break out south of Philadelphia, closer to far south Jersey and Wilmington during the early evening.

The vertically stacked low pressure system causing this will be slow to depart and will likely affect our weather into Monday.
