URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 205
NWS Storm Prediction Center Norman OK
655 PM CDT Fri May 22 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Parts of southwest and south central Oklahoma
Northwest and north central Texas
* Effective this Friday night and Saturday morning from 655 PM
until 200 AM CDT.
* Primary threats include...
Widespread large hail and scattered very large hail events to 3
inches in diameter likely
Scattered damaging wind gusts to 70 mph possible
A tornado or two possible
SUMMARY...Splitting supercells will likely persist into the
overnight hours, with the northernmost hail threat potentially
reaching parts of central Oklahoma. Additional storm development is
expected across northwest Texas this evening. The storm environment
is favorable for very large/damaging hail with the supercells, as
well as damaging winds. A tornado or two will be possible this
evening as storms remain discrete, primarily near the Red River.
Upscale growth into clusters is possible through early tonight as
the storms spread generally eastward, with a continued large hail
and damaging wind threat.
The severe thunderstorm watch area is approximately along and 70
statute miles north and south of a line from 80 miles south
southwest of Altus OK to 40 miles northeast of Durant OK. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU5).
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...This severe thunderstorm watch replaces
severe thunderstorm watch number 203. Watch number 203 will not
be in effect after 655 PM CDT. CONTINUE...WW 204...

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.
