Flooding Rains End; Sun Returns

Flood advisories and warnings are posted all over the place this afternoon. A real heavy band of rain has moved up through SNE, especially in the NW suburbs of Boston and especially Worcester. Rain has been coming down in buckets, at the rate of .25" to .50" an hour, causing ponding on the roadways and a general unsafe driving condition. The rain will continue to be moderate to heavy until about 4PM, when it should start to lighten from south to north. Heavy rain may linger in southern NH until about 5-6PM. Rainfall on the order of 1-3" is quite common away from Worcester in the western part of Massachusetts and southern Vermont, where there is still hours of heavy rain to go through. Rainfall totals, when all said and done out there will range from 2-4",with local areas picking up closer to 5-6" of rain. South and east from a line from Worcester to Portsmouth, NH, rainfall totals will come down a bit, still heavy, mainly 1-2". Further southeast of Brockton, Quincy, less than 1" of rain will fall. Again it ends around the evening rush and will be all but gone by daybreak. Tomorrow will be a windy day with warm air down on the ground mixing with the very cold air over top of us, causing instability and heavy winds. We cool for Thursday and warm up again ahead of a cold front and showery Saturday. Some spots of Friday could hit 80, perhaps, not 90-95 like last Friday, but warm still for football games.

Don't worry though, showers move through on Saturday and we really cool off on Sunday with high temperatures likely staying in the low 60's along the coastal plain and upper 50's in northern Worcester County and SW NH. Low to mid 50's will probably be all NNE will be able to muster, with overnight lows going into the hard killing freeze criteria for NNE with many places getting down into the mid and upper 20's for lows and not going above freezing for 2-4 hours. Here in SNE, a few colder spots may flirt with freeze just before daybreak, but it won't be anything more than a patchy frost. Mid 60's South; Mid 50's North will be the rule going into Monday of next week with partly cloudy skies.
