Areas affected...northeast OK into southwest MO and northwest AR
Concerning...Severe Thunderstorm Watch 537...
Valid 220440Z - 220545Z
The severe weather threat for Severe Thunderstorm Watch 537
SUMMARY...Overall weakening trend is expected to continue with
storms shifting southeast across the MCD area late this evening. A
few strong gusts are possible in the short term, but the overall
severe threat has diminished. WW 537 is expected to expire as
scheduled at 05z.
DISCUSSION...Radar trends over the last hour or so indicate gradual
weakening is occurring with line of storms extending across
northeast OK into southwest MO. Both 5 and 9 km CAPPI has shown a
marked decrease in reflectivity. Severe gusts of 58 mph were last
measured near Talala in Rogers County OK about 40 minutes ago. Other
regional observations indicate wind gusts in the 35-45 kt range. As
storms continue southeast across northeast OK and into northwest AR
expected continued weakening with some gusty winds possible. Where
counties remain in WW 537 across parts of southwest MO, a few strong
gusts are possible, but as boundary layer inhibition has increased,
severe threat has become quite limited. A downstream watch is not
expected and WW 537 will expire at 05z.
