This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...Today and Tonight

Scattered showers will diminish over the far northeast plains by 7
am this morning. There will be some drying moving into Northern
Colorado later this morning and afternoon which will limit
thunderstorm activity, especially over far northern sections. The
brunt of the storms today will be along and south of the
Interstate 70 corridor. Heavy rain, small hail, wind gusts to 40
mph can be expected with the stronger storms. Slow moving storms
will have the potential to produce a quick inch of rain in a very
short time.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

A return to drier and warmer weather Sunday and Monday will give
way to a greater chance for thunderstorms, particularly in the
high country Tuesday through Friday with monsoon moisture flowing
up from the Desert Southwest. Some high country storms midweek
could produce brief heavy rainfall, while storms on the plains may
produce more gusty winds than soaking rainfall.


.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected to be needed today or tonight.

This hazardous weather outlook is for eastern Utah and western
Colorado.

.DAY ONE...Today and Tonight

Drier air will continue moving in from the north resulting in a
decrease in thunderstorm coverage today compared to the previous
few days. Thunderstorm activity will be focused mainly over the
higher terrain during the afternoon and evening, with the best
chances across the central and southern mountains and adjacent
southern valleys. Locally heavy rain, small hail and gusty winds
are possible with storms today. Flash flooding concerns will be
more localized over steeper terrain and not as widespread as
previous few days.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

A drier airmass will be over the region Sunday, resulting in
reduced thunderstorm coverage through Monday with storms limited
to mainly the higher terrain during the afternoon. Another surge
of moisture moves in as early as Tuesday, resulting in an increase
in thunderstorm activity through the coming week.

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

.DAY ONE...Today and Tonight

Scattered to numerous showers and thunderstorms will develop
across the mountains this afternoon, then spread into the El Paso
county region during the late afternoon and evening. With monsoon
moisture over the area today, the main threats with thunderstorms
will be locally heavy rain and localized flash flooding. Burn
scars, the Chalk Cliffs near Mt Princeton, and the urban area of
Colorado Springs will be particularly susceptible to flash
flooding today should a stronger storm impact these areas.

Storms across El Paso county will also have the potential to
becoming marginally severe late this afternoon through this
evening, with hail up to the size of quarters and wind gusts to
near 60 mph possible. Strong thunderstorm outflow winds will
combine with a cold front which will move through the remainder of
the southeast plains early this evening. Gusts to around 40 to 50
mph will be possible with the front as it drops through the
region, particularly along and north of highway 50...including the
Pueblo area.

All storms today will produce dangerous lightning. Lightning
activity is expected to be high, especially across the mountains
and El Paso county.

Thunderstorms will decrease after midnight, however scattered
showers and isolated thunderstorms will be possible through the
night across the mountains. The risk for flash flooding will
decrease considerably after midnight for most areas, however the
newer burn scars such as Junkins and Hayden Pass will remain
susceptible should they be impacted.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Thunderstorms will increase in coverage across the southeast
plains Saturday afternoon and evening. These thunderstorms will
bring very heavy rainfall. Flash flood prone areas may experience
rapid runoff and high water during the heavy downpours.

Scattered thunderstorms are expected across the southeast plains
and in the higher terrain again Sunday afternoon and evening. The
primary hazards with these thunderstorms will be heavy rain and
flash flooding.

The atmosphere dries out Monday through Wednesday with only
isolated thunderstorms expected. There may be an increase in
thunderstorm activity again late Wednesday and Thursday.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening across the mountains and El
Paso county.
