This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Hot and dry air will spread from the desert southwest over
Colorado today. Near record temperatures are expected, with highs
in the 90s on the plains, and upper 70s and 80s in the mountains.
There will be isolated late day thunderstorms in the mountains
that may produce localized wind gusts to 40 mph but little or no
rain. The fire danger will continue to creep up as grasses dry
out, with high fire danger across the mountain valleys and

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Abnormally warm temperatures and low daytime relative humidity
will elevate the wildland fire danger across the region through
Thursday. Isolated gusty thunderstorms each afternoon and evening
will further add to this danger, particularly in areas along and
west of the Continental Divide. There will be a better chance of
thunderstorms east of the Continental Divide on Friday following
the passage of a relatively strong cold front. Cooler temperatures
and higher relative humidity behind this front should temporarily
reduce the fire danger in the foothills and on the plains.
Temperatures will remain relatively cool across the plains Saturday
through Monday.


Spotter activation will not be needed today or tonight.
