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 in excess of 5
degrees above average. Terrain based showers and thunderstorms on the
terrain increase this afternoon with dry lightning and gusty
outflows possible under collapsing storms. Wildfire smoke will remain
visible across the southern half of the CWA.
.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
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 week. Increased moisture will slowly erode
chances for dry lightning later in the week. Wildfire smoke will
remain visible for much of eastern Utah and western Colorado early
this week. Wetting rains later in the week could help diminish smoke.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not expected at this time.
