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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms will continue to develop this
morning over the mountains and gradually spread over the plains
through late morning and afternoon. Showers will become more
numerous this afternoon, especially west of I-25 and south of
Interstate 70 across Jefferson, Park and Douglas counties. Main
impacts will be heavy rain with rainfall rates upwards of 1.5
inches of rain in less than an hour with the strongest storms.
Further east over the plains, storms will be less intense and
lower in areal coverage.

.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
reports of heavy rain and flooding will be appreciated.
