This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Scattered thunderstorms will develop this afternoon in and near
the mountains, and move east across the plains in the late
afternoon and early evening. Over the mountains the main threats
are lightning and wind gusts to 40 mph. On the plains a few severe
storms are possible. The main threat is east of a line from
Cheyenne to Limon between 4 PM and 8 PM. Hail up to ping-pong ball
size and wind gusts to 65 mph are possible. An isolated tornado
cannot be ruled out, with the greatest chance mainly east of a
line from the CO/WY/NE state line junction to Last Chance.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Showers and thunderstorms will become more numerous Saturday and
Sunday. Some of the storms on the eastern plains could become
severe on Saturday, with hail and damaging wind the main threat.
Thunderstorm chances continue on Sunday, however the risk for
reaching severe levels is less. There is also a low risk for burn
area flooding Saturday and Sunday for storms that form in the
foothills mainly east of the continental divide. Heavy rainfall is
possible in any storms on the plains. Chances for showers and
thunderstorms will continue early next week as a slow moving low
pressure system moves through.


Spotter activation is not anticipated today. It may be needed
