Time for a Cool Change

 

Aftermaths in weather conditions influenced by cold fronts following warm spells in the month of November are considerably different from their summer counterparts. Such was the situation on Thursday, November 10, 2022. By midday, temperatures had risen to the low 70s. However, the threat of approaching storms moving about 35 mph along a cold front was expected to change the summer-like conditions dramatically.
