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

.DAY ONE...Today and Tonight

Gusty winds and low relative humidity values will bring a return of
high fire danger to the southern mountains, valleys and southern I-
25 corridor region mainly along and south of highway 50.  However,
an hour or two of spotty critical fire weather conditions will be
possible across the remainder of the central mountains as well as El
Paso and Pueblo counties this afternoon.  Please avoid any
activities which could start a wildfire as conditions will be
receptive to rapid fire growth and spread.

Isolated to scattered thunderstorms will develop across the
mountains during the early afternoon and spread eastward into the
adjacent plains during the mid afternoon through evening.  The main
risks with thunderstorms across the mountains and valleys will be
localized gusty winds up to 50 mph but with little or no rainfall.
As storms move east, one or two severe thunderstorms will be
possible across the southeast plains. Initially the main risk with
thunderstorms will be gusty outflow winds up to 65 mph and isolated
lightning strikes which could spark a wild fire. As storms move east
of a line from La Junta to Kim, they will encounter more moisture
with the added risk of hail up to 1 inch in diameter, dangerous
cloud to ground lightning, and brief moderate rainfall especially as
the get closer to the Kansas border this evening.  The window for
severe thunderstorm potential will be from 2 PM to 10 PM.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Critical Fire Weather conditions will likely continue into this
week, first across the mountains and valleys, then spreading
eastward into the southeast plains late week. Thursday will be the
most concerning High Fire Danger day across southern Colorado as
gusty west winds increase ahead of another storm system.

Isolated to scattered thunderstorms will be possible Tuesday and
Wednesday across portions of the eastern mountains and plains. The
main risk with thunderstorms will be strong outflow winds and
lightning, but only spotty light rainfall amounts. However, there is
the chance for a strong to severe storm or two across the eastern
plains Tuesday and Wednesday if low level moisture behind a cold
front increases sufficiently. Hail and locally heavy rain will be
possible if this occurs.

.SPOTTER INFORMATION STATEMENT...

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