Areas affected...North-central and northeast Oklahoma

Concerning...Severe Thunderstorm Watch 493...

Valid 142348Z - 150115Z

The severe weather threat for Severe Thunderstorm Watch 493
continues.

SUMMARY...Strong to severe wind gusts remain possible with a line of
storms moving into north-central and northeast Oklahoma.

DISCUSSION...A line of strong/severe storms continues to sag
southward into northern Oklahoma this evening. Strong buoyancy is in
place in northeastern Oklahoma per objective mesoanalysis. Given
deep-layer shear parallel to the line, there has been less tendency
for stronger bowing segments to develop within this line as compared
to activity in southeastern Kansas and MRMS radar mosaic shows
outflow slightly ahead of the line. So far, Oklahoma mesonet wind
gust data shows several 40-55 mph wind gusts in northern Oklahoma.
Even so, strong cold-pool dynamics (surface observations showing
around 20 F drop in temperature behind the line) will support a
continued threat for strong/severe wind gusts over the next 1-3
hours.
