Humidex values will reach 40 to 42 Monday with the exception of areas right along the shores of the Great Lakes where values will still reach 37 to 39. Peak humidex values in the low forties are expected for the next several days due to the arrival of a more humid air mass Monday combined with temperatures in the low thirties. A change in the weather pattern is expected Thursday night or Friday and humidex values will drop below the criteria level of 40.

This is an advisory that high humidex values are expected in these regions. Monitor weather conditions and listen for updated statements.
