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

.DAY ONE...Today and Tonight

Isolated thunderstorms are expected this afternoon and evening
over the mountains and high valleys. Some isolated storms will
also develop over the southeast plains later this afternoon but
in the early evening, storms are expected to become more
widespread over the far southeast plains. A couple severe storms
will be possible, mainly east of a line from Monument to Rocky
Ford to Kim. However, Kiowa, Bent, Prowers and Baca Counties are
under the greatest threat of severe storms, with large hail up to
about 2 inches in diameter, wind gusts of 60 to 70 mph, and
locally heavy rain being the main severe threats. All storms
will produce deadly lightning and could produce gusty outflow
winds.

Another round of thunderstorms may develop overnight, as moist
outflow winds from thunderstorms spreads westward into the I-25
corridor and southeast mountains. A few strong storms will be
possible past midnight with lightning, locally heavy rainfall and
small hail possible.

Across the mountains and valleys today, the main threat with
storms will be lightning, gusty winds up to 45 mph, and brief
moderate rainfall. Thunderstorms will diminish across the western
mountains and valleys by mid to late evening.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A few strong to severe thunderstorms will be possible across the
far eastern plains of Colorado Wednesday afternoon and evening,
while the remainder of the area may see isolated storm activity.
The main threat from any of the stronger storms across the eastern
plains will be hail up to one inch in diameter, wind gusts up to
60 mph, frequent cloud to ground lightning and periods of moderate
to heavy rainfall.

Isolated to scattered thunderstorms are expected Thursday through
the weekend and into the next work week. The most likely areas to
see this activity will be over the mountains, with weak flow
keeping the activity tied to the terrain. Any thunderstorms that
develop will produce lightning, brief periods of moderate
rainfall, and a few of the strongest storms may generate wind
gusts of up to 50 mph.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
likely across the southeast plains this afternoon and evening.
