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

.DAY ONE...This afternoon and Tonight

Scattered showers will develop over the mountains early Tuesday
afternoon, with potential for some of these to spread into the
urban corridor and plains late afternoon into the evening hours.
An isolated thunderstorm will be possible as well, with locally
gusty winds and small hail the main threats. Any thunderstorms are
expected to be on the weaker side.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

No hazardous weather conditions are expected Wednesday or
Thursday. This could extend into Friday too, however the mountains
will see a chance of showers during the latter half of the day. A
more active weather pattern looks increasingly likely for the
weekend with potential for more widespread precipitation.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
