Rainy start...warm finish

Low pressure moving along the Atlantic coast will produce steady rain in Montreal today with heavy wet snow along the north shore of the St. Lawrence River north of Anticosti Island. This storm will bring 15-25mm of rain to the southwest part of the province and at least 15cm of wet snow to eastern parts of Quebec. This same low pressure area was responsible for several tornadoes last night over the Carolina's, and heavy rain once again from eastern North Carolina across the Delmarva and metro New York and into New England. This region can expect 3 to 6 inches of rain in the next 24 to 36 hours aggravating the already serious flood situation. This is the third storm to dump heavy rain on the same region in less than two weeks.

The good news is that once the rain moves out by Wednesday, we can expect a large ridge of high pressure to build in from the central US. A bubble of warm, summer like air will arrive just in time for the long Easter weekend. I expect sunshine Friday and Saturday with temperatures over 20C.
