Showers and thunderstorms developing in the high country late
this morning will slowly move east over the adjacent high plains
this afternoon. Showers and storms will be more numerous west of
I-25 and roughly south of Interstate 70, particularly in Douglas,
Elbert and Lincoln Counties late this afternoon and evening. The
main impacts from storms in this part of the outlook area will be
heavy rainfall with rates possibly up to 1.5 inches in less than
an hour. Farther north and east on the plains, storms will be less
numerous and not as intense due to more stable conditions. Most
of these storms should dissipate by mid to late evening...except
in Elbert and Lincoln Counties where they may linger beyond
midnight.


.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Upslope flow and high moisture content will continue the threat of
storms producing brief heavy rain and localized flooding issues
Thursday, especially over the high terrain and Palmer Divide.
Greater instability on Friday will bring a chance for stronger
storms, with heavy rain and strong outflow winds being the main
impacts. Isolated to scattered storms will occur each day into
next week under the slightly stagnant pattern with monsoonal
moisture being recycled overhead.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight, however
