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

This hazardous weather outlook is for northeast and north central

.DAY ONE...This Afternoon and Tonight

Snow showers will increase across the mountains this evening, and
then become widespread and heavier by Thursday morning. 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
across the far northern Counties of Colorado.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Snow will continue across the mountains Thursday morning, and then
gradually decrease by the 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 with a few rumbles of
thunder are expected to become more numerous Thursday afternoon,
with the highest coverage over the northern quarter 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.
