National Weather Service Lets Lawrence Ks Tornado Warning Expire at 11:45 p.m.

The National Weather Service let the lawrence ks tornado warning for Osage and Lyon counties expire at 11:45 p.m. The warning had covered 2 counties after a severe thunderstorm capable of producing a tornado was tracked near Allen.

At 11:17 p.m., the storm was located 4 miles south of Allen and was moving east at 45 mph. The locations listed in its path were Reading, Allen and Admire.

Osage and Lyon counties

The warning applied to both counties until 11:45 p.m., ending the immediate tornado alert for those areas. For residents in the warning zone, the practical shift was from active warning status to no longer being under that alert.

The storm description tied the warning to a severe thunderstorm with tornado potential, not just heavy rain or lightning. That put the focus on the storm’s position, speed and direction at 11:17 p.m., when it was still tracking east across the warned area.

Reading Allen Admire

Reading, Allen and Admire were the named locations in the storm’s path. Allen sat closest to the storm’s listed position at 11:17 p.m., 4 miles south of town, while the eastward movement at 45 mph pointed the system toward the rest of the warned area.

That sequence left the key operational fact for people in Osage and Lyon counties: the tornado warning had expired at 11:45 p.m., but the storm had already been moving through the area with a tornado-capable structure earlier in the hour.
