Muggy September

Posted: 21 Sep 2016 05:37 AM

The muggy weather this September continued on Tuesday with dew point temperatures reaching 70 degrees for much of the state. The featured chart presents some metrics on the number of hours each September with an average dew point at or above 70 degrees. The total for 2016 is already the third largest since 1973 according to the top panel. The bottom panel shows the average number of days each September with such a dew point temperature at the given hour. Again, 2016 totals are way above average. There is concern that the muggy weather is going to lead to mold development in the already mature agricultural crops. Once mature, a hard freeze followed by warm and dry conditions are best to help dry out the crop for harvest. So far, we have experienced neither of these this September.
