Scattered damaging wind gusts to 70 mph likely
A tornado or two possible
SUMMARY...Thunderstorms are developing along and in advance of a
cold front that will continue to move eastward and southeastward
through the evening. The storm environment ahead of the front will
favor a band of storms with embedded supercells and bowing segments,

threats.
The severe thunderstorm watch area is approximately along and 95
statute miles north and south of a line from 30 miles west of
Springfield MO to 25 miles east northeast of Springfield IL. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU2).
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.

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.
