...Red Flag Warnings 11 am this morning until 8 pm mdt this
evening, Denver Metro area, Palmer Divide, South Park, southern
Foothills and parts of the northeast and east central Plains...

...Winter Storm Watch in effect Friday afternoon through Saturday
morning for the Front Range Mountains and Foothills...

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

.DAY ONE...This Afternoon and Tonight

Strong south winds will develop over the plains today ahead of an
approaching storm system. Gusts of 30 to 40 mph will be common by
midday, with gusts to 50 mph possible. The winds will combine with
low humidities to produce very high fire danger from southeastern
Colorado north to Denver, Greeley, and Fort Morgan. While
humidities will improve this evening, the strong winds will
continue overnight. Scattered rain and snow showers will develop
in the mountains overnight, with some higher mountain areas
receiving a couple inches of snow by morning.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A spring storm will move out of Utah and across Colorado Friday
into Saturday. As a result, widespread precipitation is expected
through Saturday morning. Snow, heavy at times will be possible in
the Front Range Mountains and Foothills. Storm totals in those
areas may range from 8 to 12 inches with some areas seeing up to
18 inches by Saturday afternoon, with lesser amounts expected
over the Palmer Divide. Elsewhere across the northeast plains,
rain turning over to a mix of rain and snow then possibly to a
wet snow by late Friday will continue through Saturday morning. At
this time some light accumulation is possible, mostly on grassy
surfaces.

The storm system will exit the region by Saturday afternoon,
followed by a warmer and drier pattern for Sunday and Monday. The
next chance of precipitation for the region will be on Tuesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
