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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms will develop over the
mountains this morning, and then spread over the plains this
afternoon and early evening. Higher moisture levels today will
result in higher areal coverage of storms along with heavy rain
and gusty winds, but no severe weather is expected west of a
Sterling to Limon line. However, the overall flash flood threat
is on the lower side as storms will be moving at 10 to 20 mph.

Over the far eastern plains of Colorado east of a Sterling to
Limon line, there could be a few severe storms with damaging
winds to 60 mph and hail up to 1 inch in diameter. Best chance for
severe weather will be after 2 PM.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A front will bring cooler than normal temperatures and higher
moisture to the area Wednesday. Upslope flow will bring increased
storm coverage for the high terrain and Palmer Divide, as well as
areas west of I25. Higher rainfall rates expected over these areas
could result in localized flooding issues. Storms will have less
coverage and will be slightly drier over the plains. A similar
pattern will continue Thursday though with slightly drier
conditions. A shortwave on Friday may bring a chance of stronger
storms over the far eastern plains. Warmer than average
temperatures will spread over the area through Monday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed over far northeast plains of
Colorado after 2 pm.
