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

.DAY ONE...Today and Tonight

The airmass has dried out a bit across the forecast area which
will lessen the chances of showers and thunderstorms a little bit
this afternoon and evening. The best chance for thunderstorms will
be in Park County and along the southern foothills and Palmer
Divide with heavy rain and lightning being the primary threats.
The rest of the forecast area can expect isolated showers and
thunderstorms. The threat for flash flooding over the recent burn
areas is expected to be minimal.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

We`ll have warmer and drier weather through the middle of the
week. There will only be isolated thunderstorms over and near the
mountains in the afternoons and evenings, and the risk of burn
scar flooding will be very low. Temperatures will be near 100
on the plains Tuesday and Wednesday. Some increase in thunderstorm
activity is likely by Friday along with a little cooling.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.

Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Sunday July 25 to 400 PM Monday July 26

vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Monday, July 26, 2021.  Light winds, abundant sunshine and

advisory that are not expected to reach the Unhealthy for
Sensitive Groups (USG) air quality designation, we request that
activities, such as driving non-ZEV vehicles (i.e., gas or

worsen air quality or contribute to precursors which may also
adversely affect air quality.  For Colorado air quality
