Freezing Rain Advisory Overnight For Worcester County

A front is stalled south of New England.  It will advance north as a warm front tonight.  Initially, it may be cold enough for some Freezing Rain in Worcester County.  The National Weather Service has issued a *Freezing Rain Advisory* from 8 PM tonight until 8 AM tomorrow morning.

Although high pressure is in control to our north, there will be a few isolated showers across the region.  Some rain showers are currently approaching the Mass Pike.

It was nice and bright this morning but the cloud deck is advancing (duh, there is rain approaching) well ahead of tomorrow morning's precipitation.   Temperatures will slowly warm into the upper 30's to low 40's in Worcester County.  Temperatures are 5-10 warmer in SE MA.

By 8 PM a storm system will be lifting northeast into the Great Lakes and High pressure will slide east into Atlantic Canada.  Most of Southern New England stays dry until after midnight.  By 2 AM some precipitation is possible in Western parts of the state, but it should hold off closer to daylight.
WPC Surface Fronts/Precipitation Monday 2 AM
Temperatures as of 5 AM will be hovering near freezing in Northern Worcester County.  Roads will likely need to be treated again before the AM commute begins.
