...Winter Weather Advisory for the mountains above 9000 feet
tonight and Thursday...

This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Snow showers will increase across the mountains through this
afternoon, and then become widespread and heavier tonight. Persons
planning travel into the Colorado high country tonight should be
prepared for winter travel conditions. On the plains, isolated
rain showers can be expected this afternoon, with a low threat of
a thunderstorm. Showers may become more numerous late tonight.

Another upper level disturbance moving quickly southeast into the
region will bring the unsettled weather.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Snow will continue across the mountains Thursday morning, and then
gradually decrease by late in the afternoon or early evening.
Total snow accumulations from tonight through Thursday are
expected to range between 4 and 8 inches above 9000 feet, with
local amounts up to a foot. In the lower mountain valleys,
accumulations will mostly range between 1 and 4 inches. On the
plains, rain showers are expected to become more numerous Thursday
morning, with the highest coverage over the northeast corner of
the state.

By late Friday and Saturday, a potentially stronger storm system
is expected to drop toward the Four Corners region. Temperatures
will be turning colder with most of the precipitation from this
storm falling in the form of snow. There is still considerable
uncertainty with regard to potential snow accumulations. If
heavier snow develops, then already leafed out trees would be
vulnerable to damage. We will continue to monitor the potential
snow accumulations across northeast Colorado, so stay tuned for
the latest updates on this spring storm.

After drier and warmer conditions Sunday into Monday, the next
storm system may bring more precipitation in the form of rain and
snow by Tuesday.


Spotter activation will not be needed today or tonight.
