URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 221
NWS Storm Prediction Center Norman OK
535 PM CDT Sun May 24 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
North central into southwest Kansas
Extreme south central Nebraska
* Effective this Sunday afternoon from 535 PM until Midnight CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
Scattered damaging wind gusts to 70 mph possible
SUMMARY...Thunderstorm development is expected along a stalled front
from south central Nebraska into southwest Kansas, as well as along
a remnant dryline extending northward into southwest Kansas, and a
residual outflow boundary across central Kansas. The storm
environment primarily favors a mix of multicell clusters and a
low-end supercell threat, with storms capable of producing large
hail and damaging winds. Isolated supercells in southeast Colorado
could eventually move into far southwest Kansas later this evening.
The severe thunderstorm watch area is approximately along and 65
statute miles east and west of a line from 50 miles north northwest
of Concordia KS to 5 miles east southeast of Liberal KS. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU1).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

OTHER WATCH INFORMATION...CONTINUE...WW 217...WW 218...WW
219...WW 220...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
24020.

The "Low" category contains probability values ranging from less than 2%
to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities),
"Moderate" from 30% to 60%, and "High" from 70% to greater than 95%.
High values are bolded and lighter in color to provide awareness of
an increased threat for a particular event.
