AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
338 AM MDT TUE JUL 7 2015

.SHORT TERM...(TODAY THROUGH TONIGHT )
ISSUED AT 152 AM MDT TUE JUL 7 2015

UPSLOPE LOW CLOUDS AND AREAS OF FOG WILL PERSIST THROUGH MID
MORNING THEN BEGIN TO LIFT. SHOWERS OVER THE HIGH COUNTRY WILL
CONTINUE TO WEAKEN THIS EARLY MORNING...ONLY TO INCREASE BY LATE
MORNING...WITH SCATTERED THUNDERSTORMS ALSO DEVELOPING AND
SPREADING TO THE URBAN CORRIDOR. THIS WILL BE SPONSORED BY A BIT
OF LIFT SUPPLIED BY A WEAK UPPER TROUGH OVER THE GREAT BASIN THAT
WILL BE SLOWLY EDGING EAST TODAY AND TONIGHT. THUNDERSTORMS WILL
BE MOVING SLOWLY...SO LOCALLY HEAVY RAIN WILL BE THE MAIN
CONCERN...ALSO WITH SOUTHEAST WINDS ON THE PLAINS THERE WILL BE A
DENVER CYCLONE...WILL HAVE TO WATCH THAT TODAY FOR ANY POSSIBILITY
OF A LANDSPOUT TORNADO. OTHERWISE THE THREAT OF SEVERE WEATHER
WILL BE LOW TODAY.

OVERNIGHT...CONVECTION IS EXPECTED TO DECREASE...BUT ALSO SPREAD
EAST TO THE NORTHEAST PLAINS.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 152 AM MDT TUE JUL 7 2015

QG ASCENT ASSOCIATED WITH A WEAK UPPER LEVEL TROUGH WILL KEEP A
SOMEWHAT UNUSUAL NON-DIURNAL PRECIPITATION THREAT OVER THE CWA
THROUGH THURSDAY. SEVERE THREAT LOOKS TO BE RATHER LOW BUT HIGH
PRECIPITABLE WATER VALUES WILL KEEP A CHANCE OF HEAVY RAIN WITH
THE CONVECTION. AS THE WEEK WEARS ON THE UPPER RIDGE OVER THE
SOUTHERN PLAINS IS FORECAST TO BUILD INTO COLORADO BRING MONSOON-
LIKE SOUTHWESTERLY FLOW TO COLORADO. THIS SHOULD RESULT IN A MORE
DIURNAL PATTERN OF CLEAR TO PARTLY CLOUDY SKIES IN THE MORNING
WITH PARTLY TO MOSTLY CLOUDY CONDITIONS IN THE AFTERNOONS WITH
ISOLATED TO SCATTERED CONVECTION IN THE AFTERNOONS AND EVENINGS.
THE BEST AREAS TO SEE THIS ACTIVITY WILL LIKELY BE OVER THE HIGHER
TERRAIN...ESPECIALLY THOSE AREAS SOUTH OF INTERSTATE 70 SUCH AS
PARK COUNTY. TEMPERATURES WILL ALSO WARM IN THE LATTER PART OF THE
PERIOD.

&&

.AVIATION...(FOR THE TAFS THROUGH 12Z WEDNESDAY MORNING)
ISSUED AT 152 AM MDT TUE JUL 7 2015

AREAS OF HAZE AND FOG WILL PERSIST UNTIL AFTER SUNRISE TODAY...BUT
CEILINGS WILL CONTINUE TO SLOWLY RISE. SHORTLY AFTER NOON
SCATTERED THUNDERSTORMS WILL DEVELOP. IF ONE OF THESE CROSSES AN
AIRPORT...EXPECT LOW VISIBILITIES IN LOCALLY HEAVY RAIN AND WIND
GUSTS OF 30 TO 40 MPH. THE THREAT OF THUNDERSTORMS WILL CONTINUE
THROUGH THE AFTERNOON UNTIL 03Z THIS EVENING.
