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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms will develop this afternoon
in and near the mountains and Palmer Divide before dissipating
this evening. Expect only isolated thunderstorms over the
northeast plains by late afternoon and evening.

The stronger storms could produce brief moderate to heavy rain,
frequent cloud to ground lightning, small hail and wind gusts to
45 mph.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Shower and thunderstorm chances will increase on Tuesday ahead of a
very moist weather disturbance lifting out the Desert Southwest.
Mountain areas could see locally heavy rainfall during the afternoon
and evening hours which could result in spotty flash flooding. East
of the mountains storm chances will also increase, but with less
humidity these storms may produce more wind and lightning than
soaking rainfall. Should see a repeat in this activity on
Wednesday, although rainfall amounts are not expected to be as
great. Temperatures will also cool with readings running below
average in most areas. Thursday through Sunday look drier with
isolated to scattered thunderstorms confined mainly to the high
country. Temperatures during the period will remain near to below
average.

.SPOTTER INFORMATION STATEMENT...

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