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

.DAY ONE...This Afternoon and Tonight

Heavy rains capable of producing flash flooding will be possible
this afternoon and into tonight over most of the plains,
including the Pueblo and Colorado Springs region.  In addition,
strong to marginally severe thunderstorms will be possible over
all of the plains and adjacent southern mountain later this
afternoon into this evening.

The combination of abundant low level moisture, sufficient wind
shear and an upper level disturbance will allow for thunderstorms
to develop over the mountains by early afternoon, and then push
out onto the plains later this afternoon.  With lots of
instability available, the storms will intensify and will be
capable of producing heavy rain capable of producing flash
flooding.  The greatest threat of flash flooding on the plains
will be along and north of highway 50.

In addition, strong to marginally severe thunderstorms will be
possible across all of the plains and adjacent southern mountains.
Wind gusts to 60 mph and hail the size of ping pong balls are
expected.

In the interior mountains and valleys, locally heavy rains will be
possible. There has been an increase in rock and mud slides in the
mountains over the last few days, and with additional heavy rain
possible, the mud and rock slide threat will continue.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Rain showers and thunderstorms are expected for much of the region
Tuesday and Wednesday, with the greatest coverage along and around
the mountains. Some storms across the valleys and plains may become
strong to severe Tuesday and Wednesday, with severe wind gusts and
large hail the primary hazards. Conditions dry out Thursday and
Friday, with showers and storms returning over the weekend. Any more
organized storm may produce heavy rain Tuesday through Sunday.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely over ALL of the region this afternoon and tonight.
