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

.DAY ONE...Today and Tonight

Above normal temperatures continue today. Scattered thunderstorms
this afternoon with a few stronger storms possible on the plains.
Strong gusty winds up to 60 mph possible. Isolated showers/storms
west over urban corridor and mountains. These showers or storms
may produce outflows with variable gusts. Can't rule out the low
threat for flash flooding over the new Alexander Mountain burn
area. Heavy rain is unlikely, but it likely wouldn't take much
rain to produce impacts. Areas of smoke will also linger across
the areas as well with hazy skies.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Hot temperatures will continue over the forecast area into next
week. Areas of smoke will be a good bet as well. Isolated to
scattered late day showers and thunderstorms are expected through
Sunday. Afternoon thunderstorms coverage is expected to increase
next week, with likely coverage in the mountains and scattered
coverage on the plains Monday through Sunday. The main threat
with the storms through the weekend will be strong wind gusts
topping 40 mph and small hail. By Sunday, continuing into next
week, the threat of heavy rainfall is expected with the storms as
moisture remains over the forecast area.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
