Another round of storms for Montreal - Vermont & NY

Portions of the Queen City of Burlington, Vermont were hit by strong thunderstorms on Wednesday. (Fox 44 News)
Thunderstorms will fire up across the region today just as they did on Wednesday. The largest storms yesterday developed in the Adirondacks of New York and swept northeast across the Champlain Valley and into southern Quebec. They primarily remained south and east of metro Montreal during the daylight hours. These storms were big slow moving rain makers producing flooding in parts of Burlington, Vermont. Wind damage was also reported across upstate New York with some trees and power lines down. A second intense line raced across eastern Ontario late last night with intense lightning and gusty winds. These arrived in Montreal right around midnight rapidly crossing the city leaving about 7mm of rain here on L'Ile Perrot.

My Davis Vantage Vue stopped transmitting data at 12:12am during the height of the storm leaving me to believe it had fallen from its perch! It turned out to be an electrical problem that involved 90 minutes of cross referencing without my owners manual before I got it it up and running again. That took me to about 2am so I am a little tired today.

In any event the same air mass that prevailed yesterday exists today across the region. A Flash Flood Watch is already posted for portions of New York and all of Vermont. The potential exists for moist thunderstorms to produce a quick 1 to 2 inches of rain today across that portion of New England. Here in Montreal it is a very warm and humid 20C this morning. Expect showers and some thunderstorms to develop by noon as a cold front move southeast from Ontario. Gusty winds will also begin by midday in the Ottawa Valley and arrive in Montreal this afternoon, between 30-50km/h. The front will dry out the air but bring with it much cooler weather for Friday with a high of only 15C. The weekend looks sunny and dry with a warming trend into next week.
