...SEVERE STORMS POSSIBLE OVER THE NORTHEAST PLAINS THIS
AFTERNOON AND EVENING...

...VERY HIGH FIRE DANGER AGAIN OVER THE PALMER DIVIDE AND HIGH
MOUNTAIN VALLEYS...

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

.DAY ONE...TODAY AND TONIGHT

HIGH MOISTURE LEVELS TODAY WILL LEAD TO THE POTENTIAL FOR SEVERE
STORMS OVER THE PLAINS BY LATER THIS AFTERNOON. A DENVER
CONVERGENCE ZONE WILL SET UP FROM DOUGLAS COUNTY AND EXTEND
NORTHEAST THROUGH CENTRAL PORTIONS OF ADAMS AND ARAPAHOE COUNTIES
BY EARLY AFTERNOON. THIS WILL SPARK STORM INITIATION ALONG THE
BOUNDARY. STORMS WILL THEN MOVE EAST AND NORTHEAST OVER THE
PLAINS THROUGH THIS EVENING WITH SEVERE STORMS POSSIBLE AS THEY
MOVE INTO THE DEEPER MOISTURE. THE BEST CHANCE FOR SEVERE STORMS
WILL BE JUST EAST OF DENVER AND EXTENDING THROUGH ALL THE
NORTHEAST PLAINS. EXPECT LARGE HAIL UP TO 2 INCHES IN
DIAMETER...DAMAGING WINDS TO 60 MPH AND EVEN AN ISOLATED TORNADO
ARE ALL POSSIBLE WITH THE STRONGEST STORMS.

SOUTH TO SOUTHWEST WINDS WILL ALSO DEVELOP THIS AFTERNOON OVER THE
MOUNTAINS AND PALMER DIVIDE...WITH GUSTS IN THE 20 TO 30 MPH
RANGE. THIS WILL CREATE VERY HIGH FIRE DANGER AGAIN...ESPECIALLY
IN AREAS SOUTH AND SOUTHWEST OF DENVER. THE SOUTH WINDS WILL
LIKELY BRING SMOKE FROM THE BLACK FOREST FIRE TOWARDS DENVER AGAIN
THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

IT WILL BE HOT AND DRY OVER MUCH OF THE OUTLOOK AREA FRIDAY AS
SOUTHWEST FLOW ALOFT CONTINUES ACROSS THE REGION. COOLER
CONDITIONS WILL PREVAIL SATURDAY THROUGH MONDAY FOLLOWING THE
PASSAGE OF A COUPLE OF COLD FRONTS. ONE FRONT WILL MOVE ACROSS THE
AREA LATE FRIDAY NIGHT WITH ANOTHER FRONT EXPECTED SUNDAY NIGHT.
THERE WILL BE A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS...WITH
A FEW SEVERE STORMS POSSIBLE DURING THE AFTERNOON AND EVENING
HOURS SATURDAY AND AGAIN MONDAY. A DRY AND WARMER SOUTHWESTERLY
FLOW ALOFT WILL RETURN TO THE REGION ON TUESDAY AND WEDNESDAY OF
NEXT WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED OVER THE NORTHEAST PLAINS AFTER 2 PM
THIS AFTERNOON.
