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

.DAY ONE...This Afternoon and Tonight

Isolated to scattered thunderstorms will develop over the mountains
early this afternoon, then track east to southeast across the
plains from late afternoon through early evening. One or two
storms could be strong, producing winds near 60 mph and hail near
an inch in diameter. Otherwise, the primary risks from storms
today will be lightning, winds near 50 mph and local small hail.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Scattered afternoon and evening thunderstorms are expected each
day. Initial development will generally be over the Mountains
before spreading east across the Plains. The primary threats
through the period will be lightning, small hail, gusty winds and
locally heavy rain. Better instability and shear will move across
the region Sunday and Monday which may allow for a few strong to
severe storms over the Plains. If one of the area burn scars get
hit by a storm through the period, flash flooding could become a
concern.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible this afternoon and evening across the eastern
mountains, the I-25 corridor and the southeast plains.
