Peak wind gusts - Wednesday, 4/21/2021

ROANOKE, Va. – Spring cold fronts do happen, and when they do - they mean business. Highs Tuesday reached into the 70s, and we won’t see that warmth again until early next week.

In fact, temperatures will fall from the 50s to the 40s in the mountains. Temperatures in the Roanoke Valley will hold steady in the low to mid 50s. Lynchburg and Southside will go from 60s to a few degrees lower by the afternoon.

The wind will pick up once the front passes through the area by midday. Expect gusts to peak between 35 and 45 mph in areas near and to the west of the Blue Ridge Parkway.

As colder air above mixes down to the surface, we’ll see temperatures drop to about 30-35° by Thursday morning. (Check here for the latest frost and freeze alerts.) Make sure your plants are brought in or covered up. Give the pets a warm place for the night. Disconnect the garden hose, and check your tire pressure.

Once the wind calms down at night, a more widespread freeze and frost concern may develop by Friday morning. High pressure, however, will play to our advantage Friday afternoon. We’ll reach back into the 50s and 60s under a partly cloudy sky.
