Weather synopsis: Saturday November 20



12:46pm its been a cold end to the week after a stretch of warm weather that lasted from late last week through the first half of this week. The roller coaster temperature ride will continue as a warm air mass prepares to overtake the Northeast during the first half of Thanks Giving week. Temperatures will likely reach 60 degrees on Monday; the mild weather will be accompanied by rain. The rain will be associated with a cold front that will slowly creep towards the east coast through the course of week. Behind this cold front temperatures are much colder, in fact this has been the coldest air mass of the season so far with a deep winter like chill. The cold front will finally sweep through the Northeast by Friday. The forecast for Thanks Giving day calls for rain along the coast with a mixture of snow and rain away from the coast. On Black Friday, the cold front will clear the coast; though it will be very cold it should be a nice day for the Northeast with the exception of the lower Great Lakes region where Lake Effect Snow will develop.
