...SPRING STORM MOVING OUT ACROSS THE PLAINS THIS AFTERNOON...

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

.DAY ONE...This Afternoon and Tonight

Light snow will over most of northeast Colorado will gradually end
this afternoon. Accumulating snow will continue in areas south of
Interstate 70 through the afternoon, then diminish from west to
east overnight. Additional snow accumulations of 1 to 3 inches
will fall south of a line from Boulder to Limon, with areas
further north receiving little additional accumulation. Roads will
be mostly wet, but there will be some slush in the foothills west
of Denver and from Castle Rock towards Limon.

Tonight, as dry air begins moving into the state from the north,
skies will begin clearing out and temperatures will fall. Lows
across the plains will be in the 20s, leading to a damaging
freeze. Residents should take action to protect tender vegetation,
garden hoses and irrigation systems.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

There will be some lingering snow over the far eastern plains
Sunday morning with up to an inch of accumulation possible.
Otherwise, it will be dry except for a slight chance of snow
showers in the mountains.

Snow will increase in the mountains Sunday night as a weak
disturbance moves across.  On Monday there will be a chance of
snow showers in the mountains with a slight chance of afternoon
rain showers across the plains.

Another weather system will affect the region Tuesday into early
Wednesday. This system will bring snow to the mountains with a
good chance of rain across northeast Colorado.

.SPOTTER INFORMATION STATEMENT...

Snowfall reports from spotters will be appreciated.
