A late season tornado near Tipton, Oklahoma on Monday.

A very mild air mass remains over southern Quebec this morning with Montreal already above our normal daytime high for November 8. We are currently 7C after a high of 15C on Monday. Expect more of the same today after some fog and mist burns off this morning, temperatures will soar under bright sunshine to 16C. The same holds true for Wednesday, before a frontal system and associated low pressure area cross Quebec on Thursday and Friday with windy, wet weather and dropping temperatures.

We have an active weather pattern across the central portion of the continent with low pressure lifting north from Texas into the Great Lakes today. East of the center in the warm air thunderstorms produced tornadoes yesterday in Oklahoma with a farm destroyed near Tipton. The same storm system will produce more sever weather today across the lower Ohio and Tennessee Valley's, and is prompting a Winter Storm Watch across the upper peninsula of Michigan and eastern Wisconsin for Wednesday. A general 15cm of wet snow is possible in these regions extending north into northwest Ontario north of Lake Superior on Wednesday.

SEAN - Meanwhile the tropical Atlantic is showing some signs of life as sub-tropical storm Sean formed overnight. The storm is located about 720km southwest of Bermuda and is nearly stationary this morning with 45mph winds. The system is expected to remain weak and eventually merge with a frontal boundary over the open waters of the Atlantic. Sean is however enough of a threat for the Bermuda Government to issue a tropical storm watch for the island nation effective at 7am local time today.
