STRONGER THUNDERSTORMS WILL BE POSSIBLE BUT UNLIKELY TO IMPACT ANY
TERMINAL. VFR CONDITIONS WILL PERSIST... THOUGH AN OCCASIONAL MVFR

.PREV DISCUSSION...330 AM MDT FRI AUG 2 2013...
COPIOUS LOW AND MID LEVEL MONSOON MOISTURE IN PLACE FOR AN ACTIVE
THUNDERSTORM DAY AHEAD. MAIN CAVEATS TO OVERCOME REMAIN CLOUD
COVER AND MID-LEVEL ISOTHERMAL LAYER JUST ABOVE MOUNTAIN TOP
LEVEL. AREAS FAVORED WILL BE THOSE JUST UPSTREAM OF SPOTS THAT
RECEIVE SEVERAL HOURS OF SUNSHINE. THETA-E RIDGE FROM NAM12
INDICATING THAT MOST ACTIVITY WILL RUN FROM SW TO NORTHEAST WITH
ISOLATED STORMS ELSEWHERE. WEAKER STEERING FLOW WILL INCREASE
THREAT FOR LOCALIZED HEAVY RAIN AMOUNTS. ABUNDANT MID-LEVEL CLOUDS
WILL LIMIT THE THREAT FOR WIDESPREAD FLASH FLOODING AND HELD OFF
ON A FFW AFTER HEMMING AND HAWING FOR QUITE SOMETIME. ALSO...NAM
AND GFS 500MB TEMPERATURES THIS AFTERNOON ARE RATHER WARM...AROUND
-4.5C TO -5C...NOT THE BEST TEMP PROFILE FOR A COOLER THAN AVERAGE
SURFACE HEATING DAY.

DRIER AIR FROM WEST TX AND SE NM WORKS UP INTO SOUTHEAST PORTION OF
THE FORECAST AREA SATURDAY...LIMITING STORM COVERAGE SOMEWHAT. MOST
OF THE ACTION IS EXPECTED FROM THE WRN MOUNTAINS NORTH TO THE NW
PLATEAU AND EAST OVER THE NRN MOUNTAINS AND NE PLAINS...WHERE A
BACKDOOR BOUNDARY SLIDES SOUTH FROM SE COLORADO THIS EVENING.
SLIGHTLY WARMER TEMPERATURES AND MORE SUNSHINE WILL COMBINE WITH
THE ABOVE MENTIONED BACKDOOR FRONT TO LEAD TO AN UPTICK IN
THUNDERSTORM COVERAGE OVER THE MTNS...CENTRAL HIGHLANDS AND NE
HIGHLANDS AND PLAINS.

MODELS REMAIN IN GOOD AGREEMENT FOR EARLY NEXT WEEK. UNSEASONABLY
STRONG UPPER LEVEL CLOSED LOW OFF THE CENTRAL CALIFORNIA COAST
WILL BEGIN TO MOVE EWD...FORCING THE UPPER LEVEL HIGH OVER WEST
TX EWD TUESDAY AND WEDNESDAY...ALLOWING DEEP MONSOON MOISTURE TO
STREAM NORTHWARD THROUGH THE STATE AROUND MIDWEEK.

33

.FIRE WEATHER...
VERY LITTLE CHANGE EXPECTED THROUGH THE WEEKEND WITH THE UPPER HIGH
OVER WEST CENTRAL TEXAS THE DOMINANT SYNOPTIC WEATHER FEATURE. A
WEAK MONSOONAL MOISTURE PLUME OVER ARIZONA AND WESTERN MEXICO WILL
CONTINUE TO ROTATE AROUND THE UPPER HIGH CIRCULATION INTO WESTERN
AND NORTHERN NEW MEXICO AND BRING DAILY ROUNDS OF SCATTERED WETTING
SHOWERS AND THUNDERSTORMS. HUMIDITY RECOVERIES WILL CONTINUE TO BE
GOOD TO EXCELLENT EXCEPT FOR SPOTTY FAIR RECOVERIES NORTHWEST AND
EAST CENTRAL. TEMPERATURES ARE GENERALLY EXPECTED TO TREND UP
SLIGHTLY GOING INTO THE WEEKEND...ESPECIALLY CENTRAL AND WEST...AS
THE UPPER HIGH STRENGTHENS SOMEWHAT OVER THE AREA. A MIXED-BAG OF
VENT RATES WILL CONTINUE WITH SURFACE HEATING LIMITED BY CLOUDS AND
RAIN. SOME POOR VENT RATES ARE FORECAST...MAINLY WEST.

LOOKING INTO NEXT WEEK...THE UPPER HIGH IS FORECAST TO SHIFT BACK TO
THE EAST TO NEAR THE TX/LA STATE LINE BY TUESDAY. THIS PATTERN WOULD
LIKELY OPEN THE DOOR TO A MORE ROBUST MONSOONAL MOISTURE PLUME...
ESPECIALLY GIVEN THE TROUGH FORECAST JUST OFFSHORE OF CALIFORNIA...
AND LEAD TO A COOLING/WETTING TREND GOING INTO MID WEEK. MODERATE
CONFIDENCE ON THAT PATTERN DEVELOPING GIVEN SOME GOOD MEDIUM RANGE
MODEL AGREEMENT AT 144HRS.
