URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 306
NWS Storm Prediction Center Norman OK
110 PM MDT Fri Jun 26 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Eastern Colorado
* Effective this Friday afternoon and evening from 110 PM until
900 PM MDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter likely
Scattered damaging wind gusts to 70 mph possible
A tornado or two possible
SUMMARY...Scattered thunderstorms are expected to form along the
Front Range this afternoon, and spread east-southeastward over the
eastern plains through this evening. More discrete supercells are
expected initially, with the threat for large hail. Upscale growth
into clusters later this afternoon/evening will support an increase
in the threat for damaging winds. An isolated tornado cannot be
ruled out with the initial storms, especially near the Palmer
Divide.
The severe thunderstorm watch area is approximately along and 75
statute miles east and west of a line from 60 miles north northwest
of Akron CO to 50 miles west southwest of Springfield CO. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU6).
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 305...
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 500. Mean storm motion vector
29020.

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%.
