ROANOKE, Va. – We started the weekend with a brief cool-down, along with plenty of clouds and storms in the western mountains.

Some changes are in the forecast today, due in part to an approaching front from the west.

Let’s start with temperatures. We’re mainly in the 60s as I type this in the morning and we’ll see a quick warm-up into the midday and afternoon.

Most of us top out in the mid to upper 80s for highs in the afternoon, levels which are above-average for mid-June.

Isolated storms are expected to develop in the afternoon and the chance will extend into the evening.

We believe the highest coverage of storms will be in the Highlands. Chances go lower as you travel further south.

As the front passes through in the evening, high-resolution model data is showing us a line of stronger storms, especially further north.

The Weather Prediction Center (WPC) has posted a level 1 flood risk for many of us, while the Storm Prediction Center (SPC) has a level 1 severe risk north of 460.

Make sure you have a way to receive any severe weather alerts! A good resource is the Your Local Weather Authority app.

Behind the front, temperatures go up slightly as humidity levels come down a bit on Monday.

The more-noticeable drop in humidity comes by the middle of the week after a second front passes through.

The second front will also bring cooler temperatures. We’ll be below-average for highs on Wednesday and Thursday.
