LIVE Updates: Tracking Severe Storms

Severe thunderstorms are moving across NW Arkansas and the River Valley with a Tornado Watch in effect until Sunday at 11pm.

The atmosphere favors fast-moving storms with a limited tornado risk due to high wind shear.

Here is the situation as it unfolds.

Garrett Lewis January 21, 20185:13 pm


The “best spin” the atmosphere is in SE Oklahoma and West Central Arkansas and diminishes farther north. This is the area we would be most concerned with tornadoes developing quickly

Garrett Lewis January 21, 20185:11 pm

This image shows 7pm Sunday… the line should fill in with storms but the severe risk will decrease with time
