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

.DAY ONE...Today and Tonight

Scattered afternoon showers are expected to develop over the
mountains this afternoon, with potential for a few to spill onto
the adjacent plains. With low stratus expected to limit surface
heating through the first half of the day over portions of the
plains, any storms that move off the higher elevations will likely
struggle to maintain their instability as they enter a capped
environment, but there will be enough instability and modest shear
in areas on the Palmer Divide and in the mountains along and south
of I-70 that will allow for isolated severe hail and wind gusts
to be possible.


.DAYS TWO THROUGH SEVEN...Sunday through Friday

Afternoon showers and storms are expected to develop over the
higher terrain each day this week, with increasing chances of
making their way onto the lower elevations from Tuesday onward. A
shortwave passing over the Rockies by mid-week will bring more
widespread showers and storms and a brief reprieve from the 90s
for portions of the plains.




.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
