January 21st, 2012 Forecast

Snow's on the way...along with a bunch of other precipitation types.  It's not the world's biggest storm but it is winter and temperatures will be cold enough to support at least some snow early Saturday morning across most of the region.  That snow will gradually transition to rain from south to north and gradually the city will see at least some rain or icy rain on Saturday as well.  It does look more likely that frozen or freezing precipitation will hold serve to the north and west of the city -- rain does not look likely there on Saturday morning.   We will have a more thorough post with forecast totals sometime between 6 and 7 PM.

Snow will start up between 1 and 4 AM, with that transition to rain taking place south and east of the city towards morning, and perhaps into the city around daybreak.  Temperatures will bottom out in the 20's around midnight and gradually rise from the city on southeast towards morning.

That transition of snow to rain will reach Philadelphia just after daybreak, with a transition to icy rain into the Philadelphia burbs north/west later on in the morning hours, sleet mixed in for some locations farther north as well.   Snowfall totals in the city look to be in the 1-3" camp for now, with more to the north/west.  Most of the precipitation should wrap up around midday although rain will linger south and east of the city into the afternoon hours.   Daytime highs will range from near freezing north/west to the lower 40's along the coast to our southeast.

This Evening:   An update on the snow and wintry slop for tonight.
