...FLASH FLOOD WATCH FOR THE PALMER DIVIDE EASTWARD THROUGH
LINCOLN COUNTY THIS AFTERNOON AND TONIGHT...

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

.DAY ONE...Today and Tonight

The threat of heavy rainfall will increase today, especially from
the Palmer Divide east and southeast across east central and
southeast Colorado.

Scattered showers this morning will give way to increasing shower
and thunderstorm coverage this afternoon and evening. Stronger
storms will be capable of producing 2 inches or more of rain in an
hour. The most likely area for the stronger storms will be over
Douglas, Elbert, and Lincoln counties, the same areas that have
received heavy rainfall over the last few days. As a result, a
Flash Flood Watch has been issued for those locations for this
afternoon through tonight. Residents in the watch area should be
prepared to take action should a Flash Flood Warning be issued.
A few storms with heavy rainfall will be possible elsewhere,
which may produce flooding in burn scars and urban areas.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Monsoonal moisture is expected to continue moving over Colorado
into the middle of next week, maintaining the possibility of
thunderstorms with locally heavy rainfall. Scattered to numerous
thunderstorms are expected each afternoon from the mountains out
onto the plains with locally heavy rain being the main threat
from the storms. Thunderstorms will be capable of producing
one to two inches of rainfall 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 or Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. However,
reports of rainfall in excess of 1 inch causing flooding problems
will be appreciated.
