...FLASH FLOOD WATCH FOR THE FRONT RANGE FOOTHILLS, PALMER DIVIDE
AND DENVER AREA FROM NOON UNTIL 9 PM THIS EVENING...

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

.DAY ONE...Today and Tonight

Thunderstorms with locally heavy rainfall will occur today.
Storms will first develop across the mountains and foothills late
this morning, and then across the plains by early this afternoon
spreading east through the evening. Stronger storms will be
capable of producing 1 inch of rain in 30 minutes, and up to 2
inches in an hour from a slower moving storm. Burn scars will be
most prone to flash flooding, but the Palmer Divide and areas
north may also see very heavy rain from thunderstorms through
this evening. In the I-25 Corridor, locally heavy rain may also
occur and some street flooding would be possible should a stronger
storm move through. Isolated severe storms are also possible in
and near the Front Range with 1 inch diameter hail and wind gusts
to around 60 mph.

Storms and their intensity will gradually diminish through the
late evening hours, although a few may linger on the eastern
plains overnight.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

There will be a chance of late day showers and thunderstorms on
Monday and Tuesday. There could be heavy rainfall with some of
the storms on Monday. Wednesday and Thursday look pretty dry over
all the forecast area. There will be a slight chance of late day
showers and thunderstorms Thursday through Saturday, mainly over
the mountains. The above normal hot temperatures will return
Wednesday through Saturday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated today or tonight. However,
any heavy rain or severe weather reports would be appreciated.
