Beneficial rain on the way this week. After a sunny Sunday and Monday, our weather pattern will turn active Tuesday into Thursday. We will see two rounds of rain. Both storms will lack cold air, so most of the precipitation in New England will be liquid and not frozen. Tuesday’s storm will move into some “colder” air in New Hampshire and Maine. With a northeast wind leading to a Cold Air Damming, freezing rain is possible in the valleys of Maine and New Hampshire. This first storm will bring the region ½” to 1” of rain.
There will be a lull late Tuesday into Wednesday morning. The second system will be stronger and has potential to rapidly deepen off New Jersey Wednesday night. Winds will be the second headline of this second storm system. Gusts may approach 50 mph for coastal southern New England. Rain will be very heavy with the second system, and 1.5” - 2" is likely.
The 5-day rainfall total will range between 2” and 3” for most of New England. This will be a significant help for the drought. It’s important the rain falls before the ground freezes, otherwise it would prevent the rain from being absorbed.
This week’s drought monitor showed little change with conditions in the northeast — I guess we can be thankful that it didn’t get significantly worse. Here are some of the latest deficits:
Manchester, NH: 17.03”
Hartford, CT: 13.45”
Boston, MA: 10.85”
