most at risk.

PM thunderstorms will be mainly over the mountains, with a slight
chance over the plains on Thursday and Friday. A slight risk of
flash flooding will be possible over burn scar areas. There could
be a stray thunderstorm over the far eastern plains on Thursday
afternoon, with a very slight risk of becoming stronger or severe.
Main threat with this would be strong and gusty outflow winds up
to 60 mph, and hail up to 1 inch in diameter.

Showers and isolated thunderstorms are expected this afternoon

will be lower. Some showers may linger from Park county onto the
plains south of Interstate 70 through the evening, but the threat
of heavy rain will be lower after sunset.

Drier weather is expected Wednesday and especially Thursday,
though there will still be some afternoon storms over the

in thunderstorm activity is expected for the weekend.


Spotter activation will not be needed today or tonight. However,
any reports of heavy rainfall or flooding would be appreciated.
