URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 144
NWS Storm Prediction Center Norman OK
555 PM CDT Fri Apr 22 2022
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Exrtreme eastern Colorado
Western Kansas
Extreme southwestern Nebraska
* Effective this Friday afternoon and Saturday morning from 555
PM until 100 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 75
mph likely
Scattered large hail and isolated very large hail events to 2.5
inches in diameter likely
A tornado or two possible
SUMMARY...Thunderstorms will continue to develop north-northeastward
into western Kansas this evening along a dryline, where the storm
environment favors supercells with very large hail up to tennis ball
size (2.5 inch diameter), and thunderstorm outflow gusts up to 75
mph, and perhaps a tornado late this evening. Toward about 11pm to
1am CDT, the dryline will retreat to near or west of the
Colorado/Kansas border, with additional thunderstorm development in
a line expected. Damaging winds and large hail will be the main
threats with these storms, though an isolated tornado may occur with
embedded circulations in the line.
The severe thunderstorm watch area is approximately along and 55
statute miles east and west of a line from 35 miles west northwest
of Mccook NE to 30 miles west of Liberal KS. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU4).
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 141...WW 142...WW 143...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A
