...SEVERE STORM THREAT TODAY AND MONDAY...

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

.DAY ONE...Today and Tonight

A couple severe thunderstorms are expected to develop across the
northeastern plains of Colorado this afternoon. A dryline is
expected to be the focus for the storm development, and by early
to mid afternoon it should be organizing from near Cheyenne
Wyoming to between Greeley and Fort Morgan and then southward to
near Limon. High instability along and east of the dryline
combined with sufficient wind shear will bring a threat of storms
with very large hail, damaging winds, and a possible tornado.
Storms are first expected to develop between 1 and 3 PM, and then
move northeast across the northeast plains of Colorado through 6
PM. After that time, the threat of any severe weather will
decrease.

Dry weather will persist across the Denver area and points
southwest this afternoon. A few showers and storms later this
evening and overnight may develop back along the Front Range, but
mainly north of Denver. Fire danger will reach critical levels in
the Park County area today. Be careful to fully extinguish any
campfires this holiday weekend.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Showers and thunderstorms are expected to develop across much
of the outlook area on Monday and Tuesday. Some late day storms
on Monday could turn severe on the northeast plains and along the
northern Front Range foothills. Large hail and damaging winds will
be the main threats, but can`t rule out an isolated tornado or
two. The chance for thunderstorms will continue on Wednesday with
yet another vigorous weather disturbance moving out of the lower
Great Basin. Drier and warmer weather should then return later in
the week under a strong ridge of high pressure.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will likely be required over the northeast
plains of Colorado by 1-2 PM.
