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 and dry conditions keep temperatures trending 5 degrees above
average. Scattered showers and isolated thunderstorms on the terrain
increase this afternoon with dry lightning and gusty outflows
possible under collapsing storms. Wildfire smoke will remain visible
across the central and southern areas of the CWA.
.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
Hot and dry conditions will continue through the week. Afternoon
showers and storms on terrain will remain in the forecast,
increasing in coverage through the latter half of the week.
Increasing moisture will limit chances for dry lightning later in
the week and bring increased chances for wetting rain across the
higher terrain. Wildfire smoke will remain visible for much of
eastern Utah and western Colorado though the wetting rains later in
the week could help diminish smoke. Conditions dry out Sunday into
early next week.
