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

.DAY ONE...Today and Tonight

Scattered to numerous thunderstorms will develop over the
mountains and foothills this afternoon, with the highest coverage
south of I-70 and in South Park. Stronger storms will be capable
of producing locally heavy rain, small hail, and gusty winds.
Localized minor flooding is possible along poor drainage areas.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Scattered showers and storms will occur over the mountains again
on Tuesday afternoon, with a few of these spilling onto the
plains. An isolated stronger storm will be possible in the
northeast corner of the state late in the day. Wednesday will
likely be drier with summer-like heat.

More active weather and at least scattered thunderstorm coverage is
expected by Thursday. A couple of those storms may become severe.
The chance of thunderstorms will linger into Friday, the Fourth
of July, although the latest trends would show a decrease in storm
coverage through the Fourth of July weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. However,
any heavy rain reports from the high country would be
appreciated.
