New rounds of Mid-Atlantic rain and Canada wildfire smoke

We pick up this week where the last one left off. Rain and heat continue to plague many regions. In others, it’s fire. Sounds like summer.

Weather Watch

Neverending rain. Another heavy rain threat is focused on the Mid-Atlantic urban corridor Monday. It’s a level 3 of 4 “moderate” risk, for the chance of several inches of rain in short order potentially leading to flooding. Soils are well saturated, given precipitation amounts running 125 to 175 percent normal over the past two months, with some spots seeing more than that. It’ll also probably rain heavily again this week after today.

Monday morning weather maps

After a bit of a lull following a raging start to the season in Canada, the North American wildfire scene is again going gangbusters. Large fires are burning from Alaska to Hudson Bay both of the border and in most of the Western states in the U.S.

Low pressure passing through southern Canada and the northern tier of the U.S. over recent days has been dragging smoke plumes along with it.

Bad air south of the border focused on the Dakotas to the Great Lakes over the weekend. Early Monday, code red unhealthy air was centered over southeast Canada, with code purple very unhealthy including the Toronto area.

Smoke may increasingly infiltrate the Northeast as a cold front pushes somewhat eastward into midweek.
