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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms are expected to develop over
the higher elevations this afternoon and spread east across the
plains. With increasing instability/shear values expected over
portions of the northeastern corner, there is an isolated threat
that developing storms may produce some large hail and severe wind
gusts across the area if the modest CIN can be overcome.
Instability will be lacking over the higher terrain and urban
corridor today, but DCAPE values are expected to reach upwards of
1500 J/kg this afternoon, which would be conducive to stronger
downdraft potential and a few stronger to severe wind gusts
developing. With fairly weak winds aloft and PWATs slightly above
normal, we could see a few slower moving storms produce brief
heavy rainfall, generally over the mountains and foothills where
moisture is greatest.


.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Afternoon and evening showers and thunderstorms are expected each
day through the weekend, with the best chance being on Saturday.
For early next week, very warm and drier weather is expected.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
