Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Sunday June 26 to 400 PM Monday June 27

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. Monday, June 27, 2022.  Although air quality will be Good on
Sunday, ozone concentrations are expected to be much higher on
Monday. Ozone concentrations in the Unhealthy for Sensitive Groups
category will be most likely Monday afternoon and evening for
southern and western portions of the Denver metro area, including

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

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Isolated to scattered showers and thunderstorms are expected to
develop over mainly the mountains and mountain valleys this
afternoon into this evening. If those showers develop over a burn
scar or the chalk cliffs, flash flooding will be possible. A few
storms may move east into the Interstate 25 corridor, especially
across El Paso and Pueblo Counties. While the risk of severe
weather is low at this time, a few stronger storms capable of
producing wind gusts to around 50 mph and hail to the size of
pennies are possible.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Isolated to scattered higher based afternoon thunderstorms will
remain possible into the middle of the work week, with the best
coverage of storms expected over the higher terrain. More widespread
showers and thunderstorms will return for later in the work week
and into the 4th of July Holiday weekend, with an expected
resurgence of available moisture across the Rockies. This will
again lead to an increased threat of flash flooding, especially
over area burn scars.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible over portions of the region.
