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

.DAY ONE...This Afternoon and Tonight

Strong to severe storms are expected over the far eastern plains
this afternoon and evening. Very large hail greater than two
inches and diameter and wind gusts in excess of 75 mph will be
possible over the far eastern plains late this afternoon and early
evening. An isolated tornado can not be ruled out.

Storms will develop over the mountains early this afternoon before
spreading eastward onto the plains by mid afternoon. As the
storms move across the I-25 corridor region, they will be capable
of gusty winds to 50 to 60 mph and small hail. As the storms
continue to move farther east onto the far eastern plains, they
will interact with a very unstable atmosphere and will have the
potential to become quite severe. The greatest potential for
severe thunderstorm activity will be across Kiowa, Bent, Prowers
and Baca counties.

Over the mountains, more isolated to scattered thunderstorms are
expected. Lightning, locally heavy rainfall and wind gusts to 45
mph are possible. There is limited potential for burn scar flash
flooding if a storm should develop over one of the newer scars.

Hot temperatures will continue across the plains with 90s to lower
100s this afternoon. Take precautions to limit exposure to heat and
drink plenty of water.

Spotty critical fire weather conditions are anticipated over
portions of the Upper Arkansas River Valley and southern San Luis
Valley for a few hours this afternoon.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Strong to severe storms will again be possible over the plains on
Tuesday and Wednesday, with a risk of winds over 60 mph, hail up
to golf ball size, locally heavy rainfall and frequent cloud to
ground lightning. Farther west over the mountains and interior
valleys, scattered thunderstorms are expected both Tuesday and
Wednesday, with hail up to nickel size, winds of 50 mph, brief
heavy rainfall and frequent cloud to ground lightning all
possible. There will also be the possibility of flooding of burn
scars across mainly the eastern mountains each day, with the
greatest risk over the Spring burn scar on Wednesday afternoon and
evening.

For the remainder of the week into the weekend, scattered
afternoon and evening thunderstorms are expected each day, with
the greatest chance for storms over the mountains. Locally heavy
rainfall, frequent lightning, small hail and wind gusts to 50 mph
will be possible with any stronger storms.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
likely along and east of Interstate 25 this afternoon and
evening, with the greatest potential for significant severe
weather over the far eastern plains.
