Monsoon's Quick Winter Weather Update

An update on my thinking for this tricky storm:

 

A period of light snow and sleet will move through this morning; then in the early afternoon we’ll see a lull in precipitation until a larger area of moisture comes through. In the very late afternoon and evening look for snow, mainly. Overnight and into Wednesday morning we’ll see a mix of snow and sleet generally, with the event ending as freezing drizzle or just plain scattered rain showers on Wednesday morning.

 

Totals:

 

2-3 inches of snow mixed with sleet in the Reading area; perhaps an inch or two more in northern Berks and the Lehigh Valley.

 

An inch or two of snow mixed with plenty of sleet and freezing rain in Lancaster County, southern Berks, Chester and Montgomery Counties.

 

Mainly rain with perhaps a coating to an inch of sleetish slop in the Philadelphia area and points south.

 

Adjusted cancellation predictions:

 

Tuesday early dismissal: 55%

Wednesday delay: 75%

Wednesday cancellation: 35%
