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

.DAY ONE...Today and Tonight

Thunderstorms will develop across the southeast mountains early
this afternoon, and spread into the adjacent I-25 corridor and
southeast plains after 2 PM. A few of these storms could become
severe as they move off the mountains, producing hail up to the
size of golf balls and wind gusts up to 65 mph.

Isolated thunderstorms will be possible across the western
mountains and interior valleys this afternoon. However with less
moisture available in the atmosphere, these storms will be more
likely to produce gusty winds up to 50 mph and lightning, and only
spotty light rainfall amounts.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Near critical fire weather conditions are expected to develop
across all of the region on Thursday due to a combination of gusty
southwest winds, low humidity values and very warm temperatures.

From Friday into the weekend, and into next week, a more wetter
pattern is expected over the region, especially over the
mountains. Some of the showers and storms will be capable of
locally heavy rain, especially this weekend. The primary threats
from thunderstorms during this period will be locally heavy rain,
winds gusts to 45 mph and cloud to ground lightning.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible this afternoon into this evening across the all of southeast
Colorado plains.
