Areas affected...Northern/Central Oklahoma

Concerning...Severe Thunderstorm Watch 261...

Valid 120437Z - 120630Z

The severe weather threat for Severe Thunderstorm Watch 261
continues.

SUMMARY...Damaging wind gusts are possible with a thunderstorm
cluster as it propagates from north-central into central Oklahoma
into the early-morning hours.

DISCUSSION...A small MCS has evolved over the last few hours along
the KS/OK border. This activity initially struggled to grow upscale
due to very warm 2-3km temperatures. However, an expanding precip
shield/cold pool appears to have developed such that the MCS is now
surging a bit quicker along the I-35 corridor. The leading edge of
this activity is moving at roughly 25kt suggesting it could approach
the northern Oklahoma City metro by 06z. Winds have recently gusted
to 78 mph in northeast Kay County and damaging winds are the primary
severe threat as this activity propagates south. There is some
concern that propagation may spread a bit west of the initial watch,
continuing south through the metro. Given the 700mb temperature
observed at OUN this evening was 19C, if the cold pool weakens the
MCS will likely become even more elevated in nature and weaken.
