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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms will develop over the
mountains and plains this afternoon. The stronger storms will be
over far Northeast Colorado where there is better low level
moisture. Storms may approach severe limits with gusty winds near
60 mph and some hail. Further west over the urban corridor, expect
more gusty winds up to 45 mph with the storms.

Showers and thunderstorms will diminish from west to east later
tonight.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A few thunderstorms may remain Wednesday morning over the far
northeastern plains, before scattered showers and thunderstorms
again form across the forecast area later in the day.

A slow moving system will begin to push into the area Wednesday
evening to bring cold and wet weather to the area through Friday
at least. Temperatures will be 20 to 30 degrees colder than normal
for this time of year. The mountains will see appreciable snowfall
amounts, especially over the Front Range mountains and foothills Wednesday
evening through Thursday when heavy snowfall will be likely at
times. Places there could see a foot or more of snowfall over
those 36 hours. Snow levels will be around 7000 feet Thursday
morning then down to near 4500 by Friday as the storm begins to
exit. Expect winter-like driving conditions over the mountains
Wednesday evening into Friday night, with snowpacked and icy roads
and near whiteout conditions at times. At lower elevations on the
Palmer and Cheyenne Ridges, snow should remain pretty slushy but
could still pose a travel impact, especially during the night
times.

Conditions will be clearing Friday evening into Saturday with
another chance of precipitation and warmer temperatures Sunday
and Monday.


.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
