URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 193
NWS Storm Prediction Center Norman OK
1215 PM MDT Sat May 22 2021

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Eastern Colorado

* Effective this Saturday afternoon and evening from 1215 PM
  until 800 PM MDT.

* Primary threats include...
  A couple tornadoes possible
  Scattered large hail and isolated very large hail events to 2.5
    inches in diameter likely
  Isolated significant damaging wind gusts to 75 mph possible

SUMMARY...A moist air mass extends across the eastern Colorado
Plains toward the Front Range and I-25 urban corridor this
afternoon. This moisture along with additional heating and upslope
low-level winds will likely contribute to severe thunderstorm
development by mid-afternoon, initially near the Front Range, with
storms subsequently developing quickly northeastward into the
adjacent Plains of east-central/northeast Colorado. Large hail
should be the most prevalent risk, but the potential will also exist
for a couple of tornadoes, and eventually damaging winds into late
afternoon/early evening as storms organize/move northeastward.

The tornado watch area is approximately along and 70 statute miles
east and west of a line from 55 miles north of Akron CO to 25 miles
southeast of Trinidad CO. For a complete depiction of the watch see
the associated watch outline update (WOUS64 KWNS WOU3).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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.

&&

AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 2.5 inches. Extreme turbulence and surface wind
gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean
storm motion vector 21030.
