The jet stream dips and lifts, causing temperature swings through the weekend

Why temperatures swing so much ahead of fall

ROANOKE, Va. – Following Monday’s cold front, temperatures Tuesday morning are starting in the 50s. It feels nice and refreshing out there! We’ll still be warm during the afternoon but with low humidity sticking around.

Humidity levels rise Tuesday night in anticipation of another cold front Wednesday. Now, Wednesday will be quite hot with highs mainly between 84 and 90°. Showers and thunderstorms favor the West Virginia-Virginia line and areas east of the Blue Ridge Parkway.

Once the front passes, humidity levels come back down. This will result in cooler mornings again Friday and Saturday.

This same front will also be what helps save the U.S. from any impact by Hurricane Larry. As the front moves east, it will help kick Larry north and east - away from U.S. soil.

As is usually the case this time of year, however, cooler air won’t linger. Highs reach back into the 80s to near 90 by the tail end of the weekend. We’ll stay dry, though, for events like the Beaver Dam Sunflower Festival and Blue Ridge Rock Fest.

Expect the heat (and somewhat lower humidity) to linger through much of next week, with high pressure over the mid-South.

High pressure’s presence will also keep any widespread rain away from the area for the next 6 to 10 days too.
