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.

Showers and thunderstorms will occur this afternoon as ample moisture
remains across the area. This convection will likely continue
overnight into the early morning hours as pieces of energy move
across eastern Utah and western Colorado and keep the convection
going.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

The northern valleys and mountains are favored for some very isolated
convection Sunday. An upper level trough will pass through on Monday
bringing another round of showers and storms. Dry air then moves in
with the next chance for any precip looking to be on Thursday
onwards.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
