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

.DAY ONE...Today and Tonight

Windy conditions are expected in the mountains and foothills with
gusts to 50 mph today. Scattered showers and thunderstorms can be
expected this afternoon and evening with a few strong to
potentially severe thunderstorms over the far northeast plains.
Elsewhere, storms will be capable of producing gusty winds to 50
mph.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A cold front will move over northeast Colorado Friday morning,
ushering in a cooler and unsettled weekend. The surface cold front
will combine with southwesterly flow aloft to make it possible for
some strong thunderstorms to develop on the plains Friday
afternoon. Large hail and damaging winds would be the primary
threats from the strong thunderstorms. The weekend will be even
cooler than Friday, with rain showers and thunderstorms possible
through the period. By Saturday night, an upper level low will be
moving over the northern half of the state with temperatures
possibly getting cold enough for snow to fall over the north
central mountains, including Rocky Mountain National Park.

Drier and warmer conditions are expected to return Monday through
Wednesday as the upper low moves out and an upper ridge begins
building over the southern Great Plains.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
