Areas affected...Southwest Kansas into the Oklahoma and Texas
Concerning...Severe potential...Watch possible
Valid 082038Z - 082245Z
Probability of Watch Issuance...60 percent
SUMMARY...Isolated severe thunderstorms capable of mainly large hail
are expected to form between 22-23Z.
DISCUSSION...Visible imagery shows outflow boundaries from southwest
KS into the eastern OK panhandle, and across the eastern TX
panhandle. South and west of these boundaries, the air mass
continues to heat with temperatures in to the mid 80s and with
dewpoints ranging from the 50s to the lower 60s. These aggregate
outflows are also reflected in the surface pressure fields with a
meso high over south central KS and north west OK. This in turn will
likely maintain southeasterly surface winds through evening, aiding
in overall shear profiles.
One or more storms are expected to form across southwest KS into the
OK panhandle prior to 00Z, with other sporadic activity possibly
developing out of the TX panhandle CU field as well west through
southeast of Amarillo. Modest northwesterly flow aloft atop the
low-level southeasterlies may support southward-moving cells,
perhaps supercellular at times, with large hail of 1.50-2.00" the
With time, activity may merge with a possible outflow or MCS
developing southeastward out of NM.
