THREAT OF SEVERE WEATHER AND LOCALLY HEAVY RAIN AGAIN TODAY AND
TONIGHT

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

.DAY ONE...TODAY AND TONIGHT

A MOIST AIRMASS IS IN PLACE ALONG WITH UNSTABLE CONDITIONS ALOFT
AND THIS WILL SUPPORT A THREAT OF SEVERE STORMS BEGINNING LATER
THIS AFTERNOON. AN APPROACHING UPPER LEVEL SYSTEM DROPPING
SOUTHEAST FROM WYOMING WILL KEEP STORMS GOING WELL INTO TONIGHT
ESPECIALLY ACROSS THE EASTERN PLAINS. COOL AIR CURRENTLY ON THE
PLAINS WILL LIKELY DELAY THE START OF STORMS THERE.

SCATTERED THUNDERSTORMS WILL INITIALLY DEVELOP OVER THE MOUNTAINS
AND FOOTHILLS THIS AFTERNOON AND THEN MOVE INTO THE FRONT
RANGE...MAINLY AFTER 3 PM THOUGH POSSIBLY EARLIER IN LARIMER
COUNTY. SOME OF THE STORMS WILL LIKELY BE SEVERE. SUPERCELL
THUNDERSTORMS WITH LARGE HAIL...DAMAGING WIND...AND HEAVY RAIN ARE
POSSIBLE. THE MAIN SEVERE THREAT WILL BE FROM HAIL ALTHOUGH THERE
IS SUFFICIENT WIND SHEAR PRESENT TODAY TO SUPPORT A POSSIBLE
TORNADO FROM STRONGER STORMS LATER THIS AFTERNOON INTO THE
EVENING. THE PRIMARY THREAT FOR A TORNADO AT THIS TIME INITIALLY LOOKS
TO BE IN THE FOOTHILLS AND ADJACENT PLAINS OF LARIMER
COUNTY...THEN POSSIBLY TO THE EAST AND SOUTH LATER IN THE
AFTERNOON AND EVENING. THUNDERSTORMS ARE EXPECTED TO BE MOVING
ENOUGH TO KEEP THE THREAT OF FLASH FLOODING LOW...THOUGH THE
STRONGER STORMS COULD CAUSE FLOODING IF THEY MOVE OVER BURN AREAS
OR CITIES. THE THUNDERSTORMS LATER TONIGHT WILL HAVE A SMALLER
THREAT OF SEVERE WEATHER BUT THE POSSIBILITY OF HEAVY RAINFALL.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

SHOWERS AND A FEW STORMS WILL LIKELY STILL BE CONTINUING WEDNESDAY
MORNING....MOSTLY OVER THE EASTERN PLAINS. A COLD FRONT WILL MOVE
INTO THE AREA WEDNESDAY MORNING AS WELL USHERING IN COOLER
TEMPERATURES. CONVECTION WILL LIKELY DECREASE OVER THE EASTERN
PLAINS BUT WILL INCREASE ACROSS THE HIGHER TERRAIN AND URBAN
CORRIDOR WITH UPSLOPE FLOW. THE STORMS WILL NOT BE AS INTENSE ON
WEDNESDAY BUT A FEW COULD STILL PRODUCE BRIEF PERIODS OF MODERATE
TO HEAVY RAINFALL.

FOR THE REST OF THE PERIOD...A DRIER AND WARMER AIRMASS WILL MOVE
INTO THE REGION. TEMPERATURES REMAIN A BIT COOLER THAN NORMAL ON
THURSDAY...THEN CLIMB BACK INTO THE 90S FOR THE REST OF THE
OUTLOOK PERIOD.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY BE NEEDED AFTER 3 PM.
