.PREV DISCUSSION...318 PM MDT SAT AUG 4 2012...
BACKDOOR COLD FRONT CURRENTLY LOCATED UP ALONG THE EASTERN SLOPES
OF THE SANGRE DE CRISTO MOUNTAINS SOUTH TO MILAGRO...THEN
SOUTHEAST TO PORTALES. SCATTERED THUNDERSTORMS FIRING OVER THE
EASTERN PEAKS AND SLOPES OF THE SANGRES AND ALONG THE CENTRAL
HIGHLANDS SOUTH TO THE SOUTH CENTRAL MTNS. THE FRONT WILL SURGE
WESTWARD THIS EVENING...INTO THE CENTRAL VALLEYS. GIVEN LATEST
MODEL GUIDANCE AS WELL AS PROGGED PRESSURE DIFFERENCES FROM
NORTHEAST TO SOUTHWEST NM INDICATING ADVISORY SPEEDS FOR THE
MIDDLE RIO GRANDE VALLEY TONIGHT. AS A RESULT...DECIDED ON WIND
ADVISORY FOR THE MIDDLE RIO GRANDE VALLEY...MAINLY DOWNWIND OF
TIJERAS CANYON AND FOR THE PLACITAS AREA...ALTHOUGH THE NAM12
SUGGESTING A STRONG SURGE NEAR CREST LEVEL/H7 WHICH WOULD FAVOR
THE WESTERN SANDIA MOUNTAIN FOOTHILLS AS WELL. GFS ON THE OTHER HAND
NOT NEAR AS DEEP WITH A LIGHT SOUTHERLY WIND AT 700 MB OVERNIGHT.
12Z KDEN SOUNDING WOULD SUGGEST THAT THE NAM MAY BE ON TO SOMETHING
AND THAT THE EAST WINDS WILL SPILL OVER THE TOP OF THE SANDIA
MOUNTAIN CREST LATE TONIGHT. LOW LEVEL ELY PUSH SHOULD KEEP ISOLATED TO
SCT SHOWERS AND STORMS GOING OVERNIGHT WITH THE POTENTIAL FOR LOCALLY
HEAVY RAIN FROM CENTRAL MOUNTAINS EAST THIS EVENING. A STRONG
STORM OR TWO IS ALSO POSSIBLE ALONG/NEAR THE FRONT GIVEN THE
STRONG VERTICAL WIND SHEAR PROFILE...WITH HAIL BEING THE MAIN THREAT.

FRONT PUSHES WEST TO THE NM/AZ BORDER BY SUNRISE SUNDAY...SETTING
THE STAGE FOR ANOTHER ACTIVE WEATHER DAY. MAIN AREA OF CONVECTION
IS EXPECTED NORTHWEST OF A GLENWOOD TO CLAYTON LINE. NAM12 HAS
BACKED OFF ON INSTABILITY/LIFTED INDEX VALUES SOMEWHAT FOR SUNDAY
AFTERNOON. THE COOLER AIRMASS AND SCATTERED TO BROKEN CLOUD COVER
TYPICALLY SPELL A LATE START TO WHAT SHOULD TURN OUT TO BE A VERY
ACTIVE LATE AFTERNOON AND EARLY EVENING FOR THE WEST AND NORTHWEST
ZONES. DECIDED ON A FLASH FLOOD WATCH FOR THE WESTERN AND
NORTHWESTERN MOUNTAINS AND VALLEYS...WITH THE LIKELIHOOD OF BACKDOOR
COLD FRONT STALLING NEAR THE CONTINENTAL DIVIDE SUNDAY MORNING...SETTING
UP STRONG SURFACE CONVERGENCE TO EASILY GET NUMEROUS STORMS
GOING. WEAK STEERING LEVEL FLOW OF AROUND 10 KTS AND RECENT HEAVY
RAINS OVER WRN AND NWRN NM WILL MAKE THIS AREA MORE PRONE TO
LOCALIZED FLASH FLOODING SUNDAY AFTERNOON AND EVENING.
ELSEWHERE...FLASH FLOODING REMAINS A CONCERN DUE TO THE WEEK FLOW
AND PRECIPITABLE WATER VALUES OF OVER ONE INCH...BUT TOUGH TO PICK
OUT ANY PARTICULAR AREA OUTSIDE OF A BURN SCAR THAT MAY HAVE AN
ELEVATED RISK DUE TO METEOROLOGICAL FACTORS. LATER SHIFTS MAY NEED
EXPAND THE FLASH FLOOD WATCH FARTHER EAST IF APPARENT SFC
BOUNDARIES SET UP FROM TODAY'S ROUND OF CONVECTION.

CENTER OF THE UPPER LEVEL HIGH EARNS ITS NAME DURING THE COMING
WEEK. THE HIGH MOVES TO JUST WEST OF THE FOUR CORNERS MONDAY AND
REMAINS NEARLY STATIONARY THROUGH THE REMAINDER OF THE WEEK.
PLENTY OF RESIDUAL MOISTURE EXPECTED TO FIRE UP ROUNDS OF MAINLY
MOUNTAIN CONVECTION EACH AFTERNOON...WITH THE POTENTIAL OF
ISOLATED STORMS MOVING OUT OVER LOWER ELEVATIONS IN A SOUTHEAST
DIRECTION MONDAY...DUE SOUTH TUESDAY...THEN SOUTHWEST OR WEST MID-
WEEK.

.FIRE WEATHER...
BACK DOOR COLD FRONT PLUNGING SOUTH AND WESTWARD ACROSS PORTIONS OF
THE FORECAST AREA TODAY. MAIN BOUNDARY EXTENDS FROM NEAR PORTALES UP
TO SANTA ROSA AND ABUTTING UP TO THE EAST SLOPES OF THE SANGRES.
THIS FRONT WILL DRIVE FURTHER SOUTH AND WEST REST OF TODAY INTO
TONIGHT. LOOKING AT SOME GUSTIER GAP WINDS ALONG THE CENTRAL
MOUNTAIN CHAIN WITH GUSTS BETWEEN 40 TO POSSIBLY EVEN 50 MPH NEAR
THE TIJERAS/ALBUQUERQUE GAP. LESS MOISTURE TO WORK WITH IN THE
WEST...ESPECIALLY NORTHWEST WITH MORE ABUNDANT MOISTURE CENTRAL
MOUNTAINS EASTWARD. THUS...WETTING RAIN WILL BE MORE PREVALENT
THERE.

DUE TO THE FRONTAL PUSH...THE BEST DYNAMICS COMBINED WITH MOISTURE
WILL SHIFT WESTWARD ON SUNDAY. LOOK FOR WETTING RAINFALL ALONG THE
CONTINENTAL DIVIDE TO THE CENTRAL MOUNTAINS FAVORING THE NORTH
CENTRAL MOUNTAINS AND NORTHWEST THIRD OF THE AREA. UPPER HIGH WILL
BE CENTERED OVER NORTH CENTRAL TEXAS.

THE MODELS STILL POINT TOWARDS AN UPPER HIGH MIGRATION EASTWARD TO
OVER OR NEAR THE FOUR CORNERS REGION THE EARLIER HALF OF NEXT WEEK.
RECYCLING IN THE FORM IF ISOLATED TO SCATTERED THUNDERSTORMS IS
EXPECTED MONDAY AND TUESDAY. TEMPERATURES WILL ALSO BE ON THE WARMER
SIDE. HUMIDITIES COULD FALL INTO THE TEENS FOR A SHORT WHILE ACROSS
THE FOUR CORNERS REGION AS WELL AS LOWER/MID RIO GRANDE VALLEY AND
EASTERN PLAINS DURING THIS PERIOD. DEPENDING ON THE POSITION OF THE
UPPER HIGH AND PERHAPS SOME SORT OF BACK DOOR INFLUENCE...WEDNESDAY
COULD SEE AN UPTICK IN STORM COVERAGE. RIGHT NOW...THE MODELS
INFLUENCE SOUTHERN AND EASTERN AREAS AND THE LATEST GFS IS MORE
BULLISH THAN THE ECMWF. SO WILL HAVE TO SEE ON THAT.

MODELS GET DRIER THURSDAY/FRIDAY OF NEXT WEEK AS THE UPPER HIGH
REMAINS OVER SOME PORTION OF THE FOUR CORNERS AREA. AT THE SAME TIME
A MID LEVEL DRY SLOT OR DRY INTRUSION SHOULD MAKE ITS WAY IN FROM
OVER THE HIGH PLAINS AND START TO REDUCE THUNDERSTORM DEVELOPMENT
ACCORDINGLY. TEMPERATURES WOULD MOST LIKELY REMAIN ABOVE NORMAL.
