This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Afternoon and evening showers and thunderstorms will develop
across most of southern Colorado today and tonight. Thunderstorms
will initiate across the higher terrain, and spread eastward
across the Plains by late afternoon into the early overnight hours.
Thunderstorms will be efficient rain producers, and flash
flooding will be possible, especially on burn scars, urban areas
or over locations with saturated soil conditions from recent heavy
rains. A Flash Flood Watch is in effect for the Aspen Acres burn
scar and most of the southeast plains. As storms spread east into
the Plains, a few may become strong to severe, with hail to one
inch in diameter and wind gusts in excess of 60 mph. The risk for
severe thunderstorms will be greatest between 2 PM and 10 PM
today.

Showers and thunderstorms will linger into the overnight hours
across northern portions of the southeast plains with locally
heavy rainfall and lightning possible.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Thunderstorms will be possible across southern Colorado Sunday and
Monday. Locally heavy rainfall will accompany thunderstorms, with
a continued flash flood risk, especially on area burn scars. As
storms move into the Plains, a couple may become strong to severe
with hail near 1 inch in diameter and wind gusts near 60 mph. The
greatest risk appears on Sunday, with a more limited potential for
severe storms on Monday.

High pressure builds across the west for mid to late week with
drier and hotter temperatures. More isolated shower and
thunderstorm activity is possible Tuesday through Friday, with
lightning and outflow wind gusts the main storm risks.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely over portions of the region.
