The Colorado Department of Public Health and Environment has
issued the following...

WHAT...Ozone Action Day Alert.

WHERE...Douglas, Jefferson, Denver, western Arapahoe, western
Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Wednesday July 08 to 400 PM Thursday July 09

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Requests to limit driving of non-ZEV
vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Thursday, July 9, 2020.  Ozone concentrations should
generally remain in the Moderate category throughout the Front
Range region on Wednesday. However, higher ozone concentrations
are expected on Thursday with some areas possibly reaching the
Unhealthy for Sensitive Groups category. Ozone concentrations in
the Unhealthy for Sensitive Groups category on Thursday are most
likely for the south and west suburbs of Denver, including
Highlands Ranch and Golden.  For areas included in this 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 diesel), be reduced to
lessen the impacts on neighboring air quality. Additional air
pollution in this region may directly worsen air quality or
contribute to precursors which may also adversely affect air
quality. For Colorado air quality conditions, forecasts and
advisories, visit:

...RED FLAG WARNING FOR THE MOUNTAINS AND HIGH VALLEYS TODAY...

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

.DAY ONE...Today and Tonight

Fire danger will be very high in the mountains and high valleys this
afternoon as winds increase and combine with much above normal
temperatures and extremely low humidity. Some of the wind prone
areas of the foothills may also see high fire danger. Avoid
burning or any outdoor activity that may produce a spark.

An isolated severe thunderstorm will be possible late this
afternoon and evening over the northeast corner of the state,
mainly along and north of a line from Sterling to Holyoke. Damaging
winds would be the main threat.

Hot temperatures can be expected again, with highs reaching the
mid 90s across most of the plains. Those working or spending time
outdoors today should stay well hydrated by drinking plenty of
water, and seek shade if possible.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Much of the upcoming week will feature hot temperatures and drier
conditions. Fire danger will be elevated once again on Friday with
high temperatures and low relative humidity values. Temperatures
will reach the mid to upper 90s across the plains and I-25
Corridor each day this week, with a few spots possibly reaching
100 Friday and Monday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated today or tonight, but any
reports of high winds associated with thunderstorms over the
northeast corner of the state would be appreciated.
