...DENSE FOG ADVISORY NORTHEAST CORNER OF COLORADO UNTIL 8 AM
MDT...

This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...Today and Tonight

Patchy dense fog from Sterling to the north and east along the
I-76 corridor will dissipate between 8 and 9 AM. For this
afternoon, isolated to scattered thunderstorms will develop, with
most of these along and south of the I-70 Corridor. A stronger
storm or two with heavy rain and some hail is possible over the
far eastern plains where more moisture and instability exists.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Patchy fog and low stratus will be possible early Tuesday morning
following a cold front. Thunderstorms will increase in coverage
each day Tuesday through Thursday as more subtropical moisture
pushes into the area. Thursday could see locally heavy rainfall
from some of the storms. Friday through Sunday will be drier but
cannot rule out isolated diurnally driven storms, especially over
the higher terrain.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
