This Hazardous Weather Outlook is for northwest Colorado, southwest
Colorado, west central Colorado, east central Utah, northeast Utah
and southeast Utah.

.DAY ONE...Today and tonight.

Hot, dry, and windy conditions continue today. Critical fire weather
conditions will be widespread today. Cured fuels in eastern Utah have
required a Red Flag Warning today for UTZ490 in the Colorado River
Basin. Winds will gust up to 35 mph around the region today, then
diminish around sunset.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

Hot, dry, and windy conditions continue Friday and through the
weekend. Red Flag Warnings continue Friday for UTZ490. Critical fire
weather conditions are likely across the CWA through Saturday thanks
to high winds and low relative humidities. Lighter winds and
scattered showers/thunderstorms return Sunday. Shower coverage
remains a low confidence forecast, thanks to inconsistent moisture
supply and model inconsistencies. Non-zero precipitation chances
remain in the forecast each afternoon next week.
