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

.DAY ONE...Today and Tonight

Isolated showers and thunderstorms will be possible today,
spreading from the mountains this afternoon onto the plains by
late afternoon or evening. Wind gusts to 45 mph and mainly just
light rain or sprinkles will be possible from the showers and
storms. However, there is a very small threat than a lone storm
or two on the plains could become strong with hail and frequent
lightning.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A couple severe thunderstorms will be possible on the eastern
plains Friday afternoon and early evening, mainly along and east
of a Sterling to Akron line. Storm coverage and intensity will see
an increase by Saturday, with a few severe storms possible along
the Front Range and I-25 Corridor. Scattered to numerous showers
and storms can then be expected through Sunday, but cooler weather
will likely limit instability and any severe storm threat.
Memorial day should see a little lower shower and storm coverage,
but temperatures remaining a few degrees below normal.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
