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.

Isolated showers and thunderstorms develop on terrain today, favoring
the San Juans. Impacts will be limited to some gusty winds, small
hail, and brief downpours. Flash flooding is not expected today.
Temperatures jump upward today to normal. Showers will taper by
evening and quiet conditions are expected across the region.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Warmer and drier conditions continue Monday, with afternoon highs
climbing a few degrees above normal and hovering there through the
week. Isolated terrain-based showers and thunderstorms remain a non
zero possibility this week. Additional monsoonal moisture is expected
to drift into the region from the south mid week. This could produce
more widespread showers for the San Juans. More abundant moisture
could arrive next weekend, based on extended model outputs.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
