This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Scattered thunderstorms will develop across the area again this
afternoon and evening. The most numerous and strongest storms are
expected to develop across the plains, roughly along and
southeast of a line from Sterling to Fort Morgan and Deer Trail.
Those storms will be capable of producing very heavy rain up to 2
inches per hour, localized flooding, some hail, and strong winds.
One or two severe storms with wind gusts around 60 mph and hail
to 1 inch in diameter will also be possible. Farther west
including most of the I-25 corridor and the mountains, most storms
will produce a brief period of heavy rain and gusty winds. Storms
are expected to gradually diminish overnight.

Patchy fog early this morning will dissipate by 9 AM.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Monsoonal moisture is expected to remain over Colorado through
this weekend, producing cooler conditions but higher humidities
than normal. Scattered to numerous thunderstorms are expected
each afternoon with locally heavy rain being the main threat from
the storms. Thunderstorms will be capable of producing rainfall
amounts of one to two inches in less than an hour, which may
cause localized flooding problems. Some thunderstorms may also
produce strong outflow winds and maybe some hail. If areas see
thunderstorm activity repeat on consecutive days, then the threat
of flash flooding problems will increase. A decrease in moisture
is not expected until Wednesday.


Spotter activation will not be needed today or tonight. However,
reports of rainfall greater than 1 inch, hail, or strong wind
gusts would be appreciated.
