Why did we have near-record highs on Monday? Why won't it last?

BRIDGEPORT, W. Va. (WDTV) - There was not much sunshine on Monday, but temperatures still made their way well into the 60s. The main reason for this is an approaching low pressure system. The counter-clockwise flow brought southerly winds to the Mountain State (and most of the eastern 1/3 of the U.S.). However, not all low pressure system bring near-record warmth with them.

An extra feature of some low pressure systems is a low level jet (LLJ). This occurs around 5,000 feet above the ground. This is a localized maximum of winds. In our case for Monday, winds at this level maxed out around 55knots (about 60mph). This allowed more warm air to move north and translated to surface (ground level) high temperatures into the middle and upper 60s.

As our storm system moves through, it will bring rain Monday into Tuesday. As the storm passes, the counter-clockwise flow will turn our winds to the north and northwest. This will pull down colder temperatures for mid-week. Perhaps a few flurries Tuesday night into Wednesday.
