URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 600
NWS Storm Prediction Center Norman OK
525 PM CDT Mon Aug 5 2024
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Northern Iowa
Southern Minnesota
Southwest Wisconsin
* Effective this Monday afternoon from 525 PM until Midnight CDT.
* Primary threats include...
A few tornadoes possible
Scattered large hail likely with isolated very large hail events
to 2.5 inches in diameter possible
Scattered damaging wind gusts to 70 mph likely
SUMMARY...Thunderstorms are forecast to intensify this evening with
several supercells expected to evolve from the initial thunderstorm
activity over southern Minnesota. A tornado risk may accompany any
established and mature supercell. The risk for large to very large
hail (1 to 2.5 inches in diameter) and severe gusts (60-70 mph) will
also increase this evening. Upscale growth into a linear cluster is
forecast later this evening with the severe threat transitioning to
mainly a wind risk, with perhaps a lingering tornado threat.
The tornado watch area is approximately along and 50 statute miles
north and south of a line from 45 miles north northwest of Spencer
IA to 45 miles north northeast of Dubuque IA. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU0).
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.

OTHER WATCH INFORMATION...CONTINUE...WW 597...WW 598...WW 599...

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.
