   Mesoscale Discussion 0014
   NWS Storm Prediction Center Norman OK
   0121 PM CST Fri Jan 10 2020

   Areas affected...Portions of northern OK and southern KS

   Concerning...Severe Thunderstorm Watch 1...

   Valid 101921Z - 102015Z

   The severe weather threat for Severe Thunderstorm Watch 1 continues.

   SUMMARY...An isolated hail threat continues across Severe
   Thunderstorm Watch 1. Additional watch issuance across this area
   will probably not be needed, but a local extension in area of
   Tornado Watch 2 to cover a small part of north-central into central
   OK is possible.

   DISCUSSION...Semi-discrete storms across Severe Thunderstorm Watch 1
   have evolved into mainly clusters over the past couple of hours as
   they develop northeastward along and behind an arctic cold front. An
   isolated hail threat may exist with this activity in the short term.
   But, messy storm modes and elevated instability quickly decreasing
   behind the front suggest that the overall severe hail threat should
   remain quite isolated. Additional Severe Thunderstorm Watch issuance
   is not expected across this area this afternoon. However, there is
   some wind and perhaps a tornado threat ahead of the cold front
   across a small part of north-central into central OK, which is
   currently just west/north of Tornado Watch 2. Even though low-level
   winds are slowly veering to southwesterly across this region, a
   local extension in area of Tornado Watch 2 may be needed given
   sufficient instability, strong effective bulk shear, and storms
   occurring across Caddo/Grady counties.
