New month - same weather

The damage continues to mount up and down the Eastern Seaboard from heavy rain, flooding and tornadoes. This street in Baltimore collapsed onto railroad tracks as a result of heavy rain. (Washington Post)
If April showers bring May flowers, where are they? More importantly what do May showers bring? I have measured close to 50mm of rain (2 inches) here on L'Ile Perrot since late Sunday night. A little less at Trudeau Airport with close to 40mm. The rain for the most part has remained within the river banks in southern Quebec, with minimal flooding being reported along the shores of Lake Champlain and the Richelieu River as well as Lake of Two Mountains according to Urgence Quebec. Showers will continue this morning in Montreal. It is good to see April over, not a record cold month by any stretch with only around 1cm of snow for Montreal, but damp and dismal just the same. The average temperature at Dorval was 10.6C around 1 degree below normal. We only managed 1 warm day, actually just a few hours on April 14 when it reached 25C. Rainfall was abundant for the month at 135.8mm. The wet, cool start to spring has left little growing in my neighborhood with no leaves to speak of on any of the trees and very few plants flowering.

The weather will be damp again today with perhaps a few peeks of sunshine this afternoon. If we see the sun it will warm up to 16C. Enjoy it as cool and showery weather returns tonight and lasting well into Monday with temperatures around 12C for highs and 7C for lows. The culprit continues to be a slow moving upper level low over the Great Lakes. This system pumped copious amounts of tropical moisture up the entire east coast on Wednesday with major flooding rains in the order of 3-5 inches from the Gulf Coast to New England and heavy rain pushing into Ontario and Quebec. The southern half of the system will move offshore today with improving weather for the deep south and middle Atlantic, while the actual low itself remains slow to traverse our area. I don't expect warmer or dry weather before next Tuesday.
