This Hazardous Weather Outlook is for portions of central
Colorado, east central Colorado, north central Colorado, and
northeast Colorado.

.DAY ONE...Today and Tonight

An isolated strong thunderstorm will be possible for the urban
corridor and plains this afternoon, with localized flooding and
gusty winds the primary threats.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Sunday afternoon and evening will see potential for more
widespread thunderstorms, locally heavy rainfall, and flash
flooding. Stronger storms will be capable of producing 1-2 inches
of rain in less than 45 minutes. Thus, the risk for flash flooding
will be quite high for the recent burn areas along the Front Range
including Cameron Peak and Calwood. There will even be a risk of
flash flooding along the I-25 Urban Corridor through the evening
hours.

Drier air moves in starting Monday, but isolated to scattered
thunderstorms can still be expected mainly in/near the Front Range
and Palmer Divide. Drier and warmer weather can be expected
Tuesday and Wednesday. The chance of thunderstorms may increase
late next week, especially over the mountains.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight but
rainfall reports would be greatly appreciated.
