AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
638 PM MDT SAT MAY 7 2016

.UPDATE...
ISSUED AT 628 PM MDT SAT MAY 7 2016

NOT MUCH ADDITIONAL THUNDERSTORM ACTIVITY EXPECTED FOR THE URBAN
CORRIDOR...EXCEPT WEST AND SOUTHWEST OF DENVER THIS EVENING. HAVE
UPDATED THE ZONES TO LOWER THE CHANCE OF THUNDERSTORMS THERE
OVERNIGHT. ELSEWHERE THE TORNADO WATCH HAS BEEN EXTENDED UNTIL 8
PM MDT FOR LOGAN...WASHINGTON...SEDGWICK AND PHILLIPS COUNTIES BUT
HAS BEEN CANCELLED FOR THE REMAINDER OF THE COUNTIES.

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 206 PM MDT SAT MAY 7 2016

THE UPPER LEVEL TROUGH WILL BE MEANDERING AROUND THE CENTRAL
ROCKIES DURING THE PERIOD. MODERATE QG SUBSIDENCE WILL ROTATE
ACROSS MOST OF THE CWA OVERNIGHT PUTTING AN END TO MOST OF THE
ACTIVITY THAT IS ONGOING AT THIS TIME. COOL AND UNSETTLED
CONDITIONS WILL PREVAIL ON SUNDAY AS QG VERTICAL VELOCITIES
SWITCH BACK TO ASCENDING VALUES...COMBINING WITH SUFFICIENT
INSTABILITY TO KEEP THE THREAT OF SOME PRECIPITATION AROUND
THROUGH THE DAY.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 206 PM MDT SAT MAY 7 2016

UPPER LEVEL HIGH PRESSURE WILL BE CENTERED OVER EASTERN WYOMING
SUNDAY NIGHT...WITH A WESTERLY FLOW ALOFT OVER COLORADO. THERE
SHOULD ENOUGH MOISTURE AND INSTABILITY AROUND TO PRODUCE SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS ACROSS THE AREA...MOST NUMEROUS
IN THE MOUNTAINS.

TUESDAY AFTERNOON AND EVENING...AN UPPER LEVEL TROUGH WILL MOVE
ACROSS THE NORTHERN AND CENTRAL ROCKIES...WITH AN 80 KT JET OVER
NORTHERN COLORADO. GFS SHOWS BANDED PRECIPITATION MOVING INTO THE
MOUNTAINS BY NOON...THEN SPREADING ACROSS NORTHEASTERN COLORADO
DURING THE AFTERNOON AND EVENING HOURS. IT LOOKS LIKE THE BEST
CHANCE FOR PRECIPITATION SHOULD BE NORTH OF INTERSTATE 70. IN
ADDITION...THERE COULD BE SOME SNOW IN THE MOUNTAINS AND HIGHER
FOOTHILLS...WITH SOME ACCUMULATION POSSIBLE ABOVE 10 THOUSAND
FEET.

WARMER AND DRIER WEATHER IS EXPECTED BY THE MIDDLE OF NEXT WEEK AS
UPPER LEVEL HIGH PRESSURE BUILDS OVER THE ROCKY MOUNTAIN REGION.
MODELS ARE HINTING AT SOME INCREASED LOW LEVEL MOISTURE SATURDAY
AFTERNOON AND EVENING WITH SOME CONVECTION DEVELOPING ACROSS THE
REGION. SINCE THIS IS ALL THE WAY OUT IN DAY 8...HAVE ONLY RAISED
POPS SLIGHTLY.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 628 PM MDT SAT MAY 7 2016

PRIMARILY VFR CONDITIONS EXPECTED THROUGH THE PERIOD. WILL KEEP
SOME SHOWERS IN THE TAFS THIS EVENING FOR KDEN/KAPA...BUT MAY
INCLUDED VCTS FOR KBJC UNTIL 03Z THIS EVENING WITH SOME
REDEVELOPMENT TO THE SOUTHWEST. DO NOT EXPECT THIS TO CONTINUE
OVERNIGHT. NORTHWEST WINDS WILL TRANSTION TO SOUTHWEST OVERNIGHT.

1100 AM MDT SAT MAY 7 2016

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

.DAY ONE...TODAY AND TONIGHT

A STRONG UPPER LEVEL TROUGH WILL IMPACT THE OUTLOOK AREA THROUGH
THE PERIOD. IN ADDITION A SURFACE LOW PRESSURE SYSTEM HAS FORMED
OVER EASTERN COLORADO AND WILL PUSH TO THE EAST OVERNIGHT. THESE
FEATURES HAVE BROUGHT ABUNDANT LOW CLOUD AND FOG TO THE FOOTHILLS
AND URBAN CORRIDOR WHILE SOME SUNSHINE EXISTS IN THE HIGH COUNTRY
AND ACROSS THE NORTHEAST PLAINS.

CONVECTION HAS BROKEN OUT IN MANY MOUNTAIN LOCALES AND PARTS OF
THE PLAINS AS OF LATE SATURDAY MORNING AND THESE AREAS WILL
CONTINUE TO SEE A THREAT OF CONVECTIVE WEATHER THROUGHOUT THE
AFTERNOON. LARGE HAIL AND STRONG WINDS WILL BE THE MAIN THREAT
WITH ANY STRONGER STORMS THAT FORM AND A TORNADO MAY BE POSSIBLE
ACROSS THE PLAINS FROM STORMS THAT IMPACT THAT AREA. THE URBAN
CORRIDOR MAY REMAIN COOL AND CLOUDY ENOUGH THAT THE SEVERE WEATHER
THREAT WILL LIKELY STAY LOW THERE DURING THE PERIOD.

MOST OF THE ACTIVITY WILL WEAKEN AND COVERAGE SHOULD DIMINISH
THROUGH THE EVENING HOURS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A CHANCE OF SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST
THIS WEEK. RAIN AND SNOW SHOWERS ARE LIKELY IN THE MOUNTAINS ON
SUNDAY...WITH SCATTERED SHOWERS SPREADING ACROSS THE PLAINS MAINLY
IN THE AFTERNOON. FOR MONDAY THROUGH WEDNESDAY THERE WILL BE
SCATTERED LIGHT SHOWERS WITH THE BEST CHANCE LATE TUESDAY. BY THE
LATER PART OF THE WEEK IT WILL BE A LITTLE WARMER AND DRIER...BUT
THERE WILL STILL BE A SLIGHT CHANCE OF SHOWERS...MAINLY IN THE
AFTERNOONS OVER THE MOUNTAINS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED AFTER 1230 OR 1 PM THIS
AFTERNOON.
