THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

PATCHY DENSE FOG WILL BE FOUND OVER EASTERN LARIMER AND WELD
COUNTIES EARLY THIS MORNING...WITH SOME EXPANSION ALONG THE SOUTH
PLATTE RIVER VALLEY INTO MORGAN COUNTY. THIS FOG SHOULD DISSIPATE
BY MID MORNING. VISIBILITIES BELOW A HALF MILE MAY BE
EXPERIENCED...MOTORISTS SHOULD USE CAUTION.

MOISTURE STUCK UNDER A RIDGE ALOFT WILL ALLOW ISOLATED TO
SCATTERED THUNDERSTORMS TO DEVELOP AGAIN TODAY. THE DIFFERENCE
WILL BE A DRIER AIRMASS WITH NO UPSLOPE FLOW. THIS WILL ALLOW FOR
SHOWERS AND THUNDERSTORMS TO INITIALLY DEVELOP OVER THE HIGH
TERRAIN AROUND NOON IF NOT AFTER...THEN SPREAD EAST ACROSS THE
ADJACENT PLAINS THROUGH TONIGHT. ALSO EXPECT LESS COVERAGE THAN
YESTERDAY...AS WELL AS DRIER SHOWERS/STORMS WITH GUSTY OUTFLOW
WINDS AND LIGHT RAIN BEING THE MAIN WEATHER EXPERIENCED. A FEW
STRONGER STORMS COULD STILL CONTAIN SMALL HAIL. OUT FURTHER EAST
OF A LINE FROM STERLING TO LIMON...WHERE MORE MOISTURE WILL BE
FOUND...SLIGHTLY STRONGER STORMS MAY BE POSSIBLE WITH LARGER HAIL
AND STRONGER OUTFLOW WINDS. THIS MOISTURE IS EXPECTED TO BE
SCOURED OUT EARLY HOWEVER...LIKELY EARLY ENOUGH TO DIMINISH ANY
THREAT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A MOIST AND UNSETTLED WEATHER PATTERN WILL REMAIN OVER THE
FORECAST AREA THROUGH MUCH OF NEXT WEEK. SCATTERED SHOWERS AND
THUNDERSTORMS WILL OCCUR NEARLY EVERY DAY...WITH THE MOST
WIDESPREAD SHOWER AND STORM COVERAGE ASSOCIATED WITH THE PASSAGE
OF AN UPPER LEVEL DISTURBANCE ON TUESDAY.

LOCALLY HEAVY RAINFALL WILL BE POSSIBLE SUNDAY NIGHT ON THE
EASTERN PLAINS...AND THEN AGAIN LATE MONDAY THROUGH TUESDAY. AT
THIS TIME...THE THREAT OF SEVERE WEATHER WOULD BE LIMITED BY
MARGINAL WIND SHEAR AND INSTABILITY IN THE ATMOSPHERE.
HOWEVER...AN ISOLATED SEVERE STORM OR TWO WILL STILL BE POSSIBLE.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY NOT BE NEEDED TODAY OR TONIGHT.
