AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
250 PM MDT SUN JUL 26 2015

.SHORT TERM...(THIS AFTERNOON THROUGH MONDAY)
ISSUED AT 1155 AM MDT SUN JUL 26 2015

SCATTERED STRONG/SEVERE STORMS HAVE ALREADY ERUPTED OVER PORTIONS
OF NORTHEAST COLORADO AS SEVERE THUNDERSTORM WATCH ALREADY ISSUED
FOR MUCH OF NORTHEAST COLORADO. THIS HAS ALSO RESULTED IN
MULTIPLE OUTFLOW BOUNDARIES MOVING TOWARDS THE METRO AREA WHICH
WILL CREATE FURTHER STORM DEVELOPMENT OVER DENVER AND EXTENDING
INTO WELD COUNTY. PW VALUES CONTINUE TO INCREASE OVER ENTIRE AREA
AND SHOULD EVEN BE OVER AN INCH OVER FRONT RANGE BY LATER THIS
AFTERNOON. STILL LESS ACTIVITY OVER NW PORTIONS OF CWA WITH DRIER
AIR AND AWAY FROM MAIN MOISTURE PLUME.

FOR MONDAY...THERE WILL BE DRIER AND EVEN WARMER AIR MOVING FROM
THE WEST AS UPPER TROF OVER NORTHERN ROCKIES INCREASES THE FLOW
FROM THE WEST AND SOUTHWEST. THERE WILL STILL BE ENOUGH MOISTURE
FOR ISOLATED SHOWERS AND THUNDERSTORMS...ESPECIALLY OVER SOUTHERN
SECTIONS OF CWA AND INTO FAR NORTHEAST COLORADO. TEMPERATURES WILL
BE EVEN WARMER ON THE PLAINS WITH READINGS IN THE MID TO UPPER
90S.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 1155 AM MDT SUN JUL 26 2015

PLACEMENT OF AN UPPER LEVEL RIDGE AND MOISTURE INFLUX WILL
BE THE MAIN PLAYERS IN THE COMING WEEK.

MONDAY NIGHT INTO TUESDAY LINGERING MOISTURE WILL KEEP A SLIGHT
CHANCE OF CONVECTION INTO THE EVENING OVER THE SOUTHERN AND
EASTERN PORTIONS OF THE REGION AS A PLUME OF MOISTURE CONTINUES TO
MOVE EASTWARD. CONDITIONS WILL DRY OUT TUESDAY AS FLOW ALOFT WILL
BECOME MORE WESTERLY WITH THE INFLUENCE OF AN UPPER LEVEL TROUGH.
A COLD FRONT IS STILL PROGGED TO MOVE THROUGH CO DECREASING
TEMPERATURES INTO THE LOWER TO MID 80S FOR THE PLAINS AND
SWITCHING LOW LEVEL FLOW TO A MORE MOIST SOUTHEASTERLY DIRECTION.
DURING THE DAY CONVECTION WILL BE POSSIBLE OVER THE SOUTHERN
PORTIONS OF THE CWA BOUNDARY IN THE MOUNTAINS MAINLY SOUTH OF
I-70. LATER THE IN THE EARLY EVENING WITH THE INCREASE UPSLOPE AND
A SURGE OF MOISTURE FROM THE SW THERE WILL BE A SLIGHT CHANCE OF
THUNDERSTORMS OVERNIGHT IN THE MOUNTAINS AND ALONG THE FOOTHILLS.

WEDNESDAY AND THURSDAY WILL SEE THE UPPER LEVEL RIDGE PROGRESS
WESTWARD PUSHING THE MOISTURE PLUME TO THE SOUTHERN PORTIONS OF
THE STATE. THIS WILL KEEP THUNDERSTORMS TO THE SOUTH OF THE METRO
AREA AFFECTING MAINLY PARK COUNTY AND THE HIGHER TERRAIN SOUTH OF
I-70. TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL WITH HIGHS IN THE
LOWER 80S. THURSDAY WILL SEE MUCH OF THE SAME CONDITIONS AS THE
UPPER LEVEL RIDGE CONTINUES TO ENTRENCH ITSELF OVER THE 4 CORNERS
REGION. HIGHS ON THURSDAY WILL BE A BIT WARMER IN THE MID TO UPPER
80S.

TOWARD THE END OF THE WEEK AND INTO THE WEEKEND THE OVERALL
WEATHER PICTURE DOES NOT CHANGE MUCH AS THE RIDGE CONTINUES TO
SPIN OVER THE 4 CORNERS REGION KEEPING THE MOISTURE TO OUR SOUTH
AND OVER THE WEST COAST. THIS WILL MAKE THE UPPER LEVEL FLOW MORE
WNW. MODELS DUE INDICATE A WEAK SURFACE TROUGH OVER THE EASTERN
COUNTIES THAT COULD BRING IN ENOUGH LOW LEVEL MOISTURE FOR SOME
LATE DAY THUNDERSTORMS. WILL MENTION SLIGHT CHANCE FOR THIS
PERIOD. HIGHS INTO THE WEEKEND WILL REBOUND WITH THE ADDITIONAL
HEATING INTO THE UPPER 80S AND LOWER 90S FOR THE PLAINS.

&&

.AVIATION...(FOR THE TAFS THROUGH 18Z MONDAY MORNING)
ISSUED AT 1155 AM MDT SUN JUL 26 2015

MULTIPLE BOUNDARIES FROM SURROUNDING STORMS WILL RESULT IN FURTHER
SHOWERS AND STORMS DEVELOPING OVER TERMINALS THROUGH EARLY THIS
EVENING. EXPECT GUSTY AND ERRATIC WINDS WITH THESE OUTFLOWS AND
BRIEF RAIN. COULD BE SOME FOG/STRATUS THAT DEVELOP LATER TONIGHT
ON THE PLAINS AND A CYCLONE MAY BRING SOME OF THIS CLOSE TO
BJC/DEN AFTER 10Z. WILL LEAVE OUT OF TAFS FOR NOW.
