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

.DAY ONE...This Afternoon and Tonight

Scattered thunderstorms will develop over the mountains early this
afternoon and push east across the plains late this afternoon and
evening. Brief heavy rain, small hail, and wind gusts to 50 mph
will be possible with the storms along the Front Range urban
corridor.

As storms progress eastward onto the plains later this afternoon
and evening, a few will likely become severe with 2 inch diameter
hail and 70 mph winds possible. A brief tornado is also possible.
The stronger storms will also produce very heavy rain, although
the faster motion of storms today should limit the threat of flash
flooding.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Storm chances are expected to gradually decrease through this
weekend, as a drier airmass spreads back across the region.
Temperatures are expected to return to normal summer heat by this
weekend, and then warm to above normal levels for the first half
of next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated today or tonight. However,
any reports of damaging winds, hail, or heavy rain will be
appreciated.
