A rapidly intensifying storm system along a cold front is approaching New England from the southwest. The center of this system will cross western New England (or eastern New York) later this afternoon and into the evening. This will result in widespread rainfall and high winds across New England. The entire region is under the gun for heavy rain while the high wind threat is primarily centered over eastern New England.

TIMING
Rainfall will come in two main waves over the next 24 hours or so. The first is now ongoing. This first round of rainfall is coming as the storm’s warm front lifts northward through the region. The warm air moving into New England rising over the cold air dam that has been set up over New England has allowed precipitation to break out well ahead of the front.
There will likely be a bit of a lull starting around midday in southern New England. This partial lull (it certainly won’t be completely dry this afternoon everywhere) will lift northward during the afternoon. The lull will come as forcing for showers will weaken once the warm front lifts north. Forcing for rain will pick back up as the cold front approaches later in the day.
