The high pressure in the Midwest will be escorting an abnormally cold airmass into the Northeast for Saturday-Sunday. Tonight temperatures will drop into the 40's.  There will be a few breaks of rain throughout the night but it will be unsettled.  Tomorrow morning the front and low pressure stall off the MA coast.  This will send waves of cold rain into New England
