This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Scattered to numerous thunderstorms are expected to develop across
the Front Range Mountains and Foothills this afternoon. A few of
these are expected to drift east onto the adjacent plains late
this afternoon and evening, but then gradually dissipate as they
attempt to move farther east. The stronger storms will be capable
of producing heavy rain, strong and gusty winds, and mainly small
hail. A quick inch of rain in 20 minutes can be expected from
the stronger storms, producing local flooding of burn scars,
streets and underpasses, and locations that received heavy rain
last night. One or two storms may approach severe limits with wind
gusts to 60 mph and hail up to 1 inch in diameter.

Storms are expected to decrease late this 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 activation will not be needed today or tonight. However,
any reports of heavy rainfall greater than 1 inch will be
