The Storm Prediction Center has issued a discussion highlighting the potential for a severe weather watch later this afternoon. This zone goes from Altus, OK eastward to Duncan, south to Highway 380 in Northwest Texas. The severe weather hazards will be damaging straight-line winds and large hail, although a brief tornado is not out of the question. However, the tornado potential is low in my opinion.
Here is the short version of the discussion from the Storm Prediction Center.
PROBABILITY OF WATCH ISSUANCE...60 PERCENT SUMMARY...AT LEAST SCATTERED STRONG/SEVERE STORM DEVELOPMENT IS EXPECTED AS EARLY AS 20-21Z. TRENDS ARE BEING MONITORED FOR THE POSSIBILITY OF A SEVERE WEATHER WATCH.
