More rain - then summer warmth

Low pressure continues to move along the Atlantic coast from Cape Hatteras north to New York City by later today. Copious amounts of moisture along with strong winds and pounding surf have been affecting the east coast for the last 24 hours. Some regions have had nearly 100mm (4 inches) of rain with another 2-4 inches is likely before it tapers off later today. Montreal received 13.2mm yesterday, before skies cleared for a frosty overnight. It reached -1C this morning with frost on the cars and a spattering of black ice on some area roadways. Another round of steady rain and gusty northeast winds will move inland towards the St. Lawrence Valley later today, but Montreal will remain on the western edge, so while the rain will be steady, we will not see anywhere near the amounts recorded along the east coast of the US.

Flooding continues to be a major issue from New Hampshire across Massachusetts and southern Connecticut and into new jersey and New York. parts of New jersey are experiencing the worst flooding in over 25 years. In Massachusetts the Governor has declared a state of emergency, and the National Guard has been called out.

After the rain tapers off late Wednesday, skies will clear out under strong high pressure, and record setting warmth and sunshine will move into the east for the Easter long weekend. Look for sunshine and temperatures approaching June values from 24 to 27C.
