AND SUNDAY FROM 10 AM TO 8 PM...

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

.DAY ONE...Today and Tonight

A Heat Advisory will be in place from 10 AM this morning through
8 PM this evening for all of the plains and urban corridor.
Temperatures are expected to reach and surpass the 100 degree mark
across these locations. Weak isolated thunderstorms and showers
are possible across portions of the high country and portions of
the eastern plains this afternoon that could produce gusty winds,
light rainfall, and isolated dry lightning.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Record or near record breaking heat will remain across the area
through Sunday. High temperatures will reach the 100 to 105
degree range across the I-25 Urban Corridor and northeast plains
both Saturday and Sunday. 90 plus degree heat can even be expected
up to elevations near 8000 feet. Avoid outdoor activities during
the heat of day, seek shade and air conditioning, and stay
hydrated. Seek medical aid immediately if suffering signs of heat
stroke.

Scattered showers and isolated thunderstorms with strong, gusty
microburst winds to 50 mph are expected Sunday afternoon and
evening. Isolated thunderstorms could produce new fire starts.

Slight relief in the heat is expected toward Monday although
temperatures will still be well above normal. Further cooling will
occur Tuesday into Wednesday with higher coverage of showers and
storms at that time. The chance of storms will linger into the
latter half of next week.

SATURDAY...

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 Friday July 12 to 400 PM Saturday July 13

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Request to limit driving gas and diesel-
powered vehicles is now in effect until at least 4 p.m. Saturday,
July 13, 2024.  Weather conditions continue to support high levels
of ozone on Friday and Saturday. The highest concentrations of
ozone are most likely for locations in and near the Denver Metro

Front Range region. 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:

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
and breathing discomfort in active children and adults and people
