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

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorms will develop across the
mountains and foothills this afternoon, with a few of these
attempting to spread east onto the plains late this afternoon and
evening. Most of the storms will produce gusty winds, light
rainfall, and occasional cloud to ground lightning. There will be
more moisture but at the same time more stability over the
northeast corner of the state. If a storm is able to move into
that environment, then a stronger storm with heavy rain and small
hail would be possible there.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Another warm and relatively dry day expected Monday, with storms
sticking mostly to the high terrain, Palmer Divide and far eastern
plains. Gusty outflow winds will be common, with a chance for a
couple stronger storms with hail over the far eastern plains.

A cold front will push in Monday night for cooler and wetter
conditions Tuesday and Wednesday. Another weather disturbance will
bring wetter weather Thursday into Friday. Another cold front will
be possible this weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
