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

.DAY ONE...Today and Tonight

Scattered thunderstorms forming early this afternoon over the
Front Range mountains and foothills will slowly drift east over
the adjacent plains through the afternoon. Storm chances on the
plains this afternoon will be greatest up along the Wyoming
border, west of Interstate 25 and over the higher terrain of the
Palmer Divide. A few storms near the Wyoming border could produce
hail at least an inch in diameter, wind gusts to 60 mph and
locally heavy rainfall. Storms elsewhere will be capable of wind
gusts to 40 mph, brief heavy rainfall and perhaps some small hail.
A quick inch of rain in under 30 minutes could cause local
flooding of burn scars, streets and underpasses, and in locations
that received heavy rain last night. Most of this storm activity
should end by mid to late evening.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Scattered to numerous thunderstorms are expected Friday across the
forecast area with a chance of stronger storms over the northern
plains. Strong outflow winds, brief heavy rain and some hail will
be possible. Similar conditions will be similar Saturday before
moisture gets pushed southwest for Sunday and Monday, where storms
will favor the high terrain slightly more. Brief heavy rain will
remain a hazard with the storms as monsoonal moisture remains
overhead or nearby.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. However,
any reports of rainfall greater than 1 inch or hail at least an
inch in diameter will be appreciated.
