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

.DAY ONE...Today and Tonight

A dry line will move east across Colorado today. Isolated to
scattered thunderstorms are expected ahead of the dry line. A few
storms could become severe east of a line from Limon to Brush with
golfball size hail and damaging winds. West of the dry line very
warm temperatures, low relative humidities, and gusty west winds are
expected to increase the fire danger. A Red Flag Warning is effect
for the mountain valleys due to the dry fuels and critical fire
weather conditions.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

There will be at least a slight chance of thunderstorms each
afternoon and evening through Saturday, the result of a series of
weak cold fronts. A few thunderstorms forming along the Palmer
Divide Wednesday afternoon and evening could become severe, with
large hail and damaging winds the principle threats. Very warm
temperatures and gusty winds on Wednesday will also keep the fire
danger elevated. Then a trend towards cooler temperatures and
slightly higher relative humidity starting Thursday will somewhat
reduce the fire danger through Saturday. A large high pressure
ridge building in from the Great Basin will return warmer and
drier conditions to the outlook area Sunday and Monday. This will
significant reduce the chance of thunderstorms and once again
elevate the fire danger.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
