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.
