Sunday afternoon may bring a few isolated to scattered thundershowers to the region. The focus area of these potential showers will be across Northern Virginia, the Potomac Highlands with a few sprinkles possible for the Mountains in Maryland along with the Eastern Panhandle of West Virginia.
Showers and storms are more likely to form along a line along and south of I-66 and the I-81 corridor south of Winchester. A few isolated showers are possible outside of this general zone, but we will have to play the weather today by ear. Be sure to tune into your WDVM Wx as you head into the afternoon and see where any of these showers are popping up.
We will be slightly less humid as we head into Monday. However, as high pressure moves to the southeast, moisture from the Atlantic will increase the amount of water vapor in the atmosphere. Moisture from Barry and the Gulf of Mexico will also impact the region as we head into the middle to late part of the week giving us uncomfortable temperatures, but a chance of a thundershower, which temporarily may relieve us from the oppressive air.
Friday, however, clouds will clear out enough to send temperatures into the 90’s with a chance of a thundershower. Heat index values could reach into the 100’s.
Here is a look at your 7-day forecast:
