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

.DAY ONE...Today and Tonight

The majority of the rain showers on the plains is expected to
shift from the eastern plains of Colorado back to near the Front
Range Foothills and I-25 Urban Corridor during the afternoon and
early evening hours. Temperatures will turn cold enough for a few
snowflakes to possibly mix in as the showers decrease overnight.
Locations along the Wyoming border in far northern Weld county
could see another 2 inches of snow, but areas farther south
including Fort Collins and Denver should not see any snow
accumulation.

In the mountains and foothills, look for snow showers to redevelop
and become more numerous through the afternoon and evening. The
heaviest snow showers are likely to develop across the Front Range
Foothills through Larimer and Boulder counties, and possibly
southward into Jefferson county. Most snowfall amounts will range
between 1 and 4 inches, but due to the heavy nature of some of the
showers local additional accumulation of 6 inches is possible in
some spots through tonight. Temperatures will be cold enough to
support some snow and slush accumulation on roads, making for
slick travel.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Scattered rain or snow showers are expected Saturday morning but
should decrease by afternoon. Warmer and drier weather are
expected Sunday and Monday as an upper ridge builds over Colorado.
From Tuesday through Thursday, a series of fast moving weather
disturbances will produce periods of light snow in the mountains
and a chance of showers on the plains each day. Temperatures will
be around seasonal normals.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
