Severe thunderstorm development is expected today and/or tonight in two areas of the country, as shown within the yellow shaded regions on the above image.
First, in the South, thunderstorms will develop along and near a stationary front and dryline from northwestern Texas into southwest and central Oklahoma. This will most likely take place on an isolated basis very late this afternoon or early this evening, with the activity expected to increase during the evening and into the overnight hours.
Large hail is likely with this activity. Some of the hailstones could exceed 2 inches in diameter, especially within the black hatched area on the image below:
Damaging thunderstorm wind gusts and a few isolated tornadoes can also be expected in this area.
At this time it appears as though a good deal of the severe weather threat in this region will take place after dark and into the overnight hours. Make sure that you have a way to receive severe weather warnings at night if you live in this region.
The other severe weather risk area for today lies across portions of the Midwest and Ohio Valley region (as shown by the yellow shaded area on the top image).
A warm front will lift Northward across this region during the afternoon and evening, with fairly widespread coverage of shower and thunderstorm activity expected to become associated with the boundary by early to mid-afternoon.
Large hail will be the primary threat from this activity, which is expected to diminish later this evening with the loss of daytime heating.
If you live across the severe weather threat areas outlined for today and/or tonight, please remain alert during the indicated time periods. Go ahead and identify your best sheltering option ahead of time, and be prepared to move there quickly if a warning is issued for your area.
