ROANOKE, Va. – After days of air you can wear, a front moving through the area will give us a much-needed break from that. Temperatures will take a bit of a dip as well, with highs Tuesday in the 70s in the higher elevations and low to mid 80s elsewhere.

A breeze out of the northwest behind our front is what will force moisture levels (dew points) to go down throughout the day.

The fact that that happens will allow temperatures to drop more at night. It might be a good idea to let the windows open, and get the flow of fresh air going.

Wednesday morning's low temperatures

In fact, we could start Thursday morning in the 40s and lower 50s! That’s your ‘average’ low temperatures for early October.

What Thursday morning may feel like

Meanwhile, the tropics stay active throughout the week. Tropical Storm Bill developed Monday night off the East Coast, and it continues to move away from U.S. soil. There are two other systems with potential for development, especially the one in the Gulf of Mexico.

Where exactly that goes is still up in the air, but it’s possible that this system throws moisture toward a front to kick off showers and thunderstorms on Father’s Day.

For now, Friday looks dry and hot. Saturday looks hot with most hit-or-miss storms west of the Parkway. Father’s Day holds a slightly better chance.
