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

.DAY ONE...Today and Tonight

Scattered thunderstorms will develop across the area this
afternoon and evening. The first storms will develop over the
mountains and foothills toward the noon hour, and then spread
eastward onto the plains later this afternoon into early evening.
Most of the storms in and near the mountains will produce light
rain and gusty winds. However, as they encounter more moisture and
instability over the eastern plains they will gain strength.
Isolated stronger storms with gusty winds up to 50 mph, brief
heavy rain, and some hail will be possible after 4 PM roughly
along and east of a line from Sterling to Akron and Deer Trail.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Subtropical moisture over the state will combine with a passing weather
disturbance to produce scattered thunderstorms from the mountains
out on to the plains Thursday afternoon.  The stronger storms may
produce heavy rainfall, hail, and gusty winds, but the threat of
flooding will be low. Friday through early next week will be
warmer with fewer thunderstorms as a strong upper ridge builds
over the Great Basin and flow over Colorado becomes drier.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
