.PREV DISCUSSION...334 AM MDT THU SEP 18 2014...
.SYNOPSIS...
RECENT FORECAST MODEL RUNS NOW SHIFT FORMER HURRICANE ODILES
REMNANT MOISTURE OVER SOUTHERN AND SOUTHEASTERN AREAS TODAY...THEN
FROM THE SOUTH CENTRAL MOUNTAINS EAST AND NORTHEASTWARD TONIGHT
THROUGH FRIDAY. A FLASH FLOOD WATCH HAS BEEN EXPANDED TO COVER
SOUTHEAST AREAS THROUGH TONIGHT AND REMAINS IN EFFECT FARTHER WEST
THROUGH TODAY. OTHERWISE...A WARMING AND DRYING TREND WILL DEVELOP
FROM WEST TO EAST FRIDAY AND SATURDAY. THUNDERSTORM CHANCES WILL
INCREASE AGAIN AND TEMPERATURES WILL FALL SUNDAY AND MONDAY AS AN
UPPER LEVEL LOW PRESSURE SYSTEM CROSSING THE CENTRAL ROCKIES DRAWS
A MODERATE MONSOON MOISTURE PLUME OVERHEAD.

&&

.DISCUSSION...
ODILES TRACK CONTINUES TO BE TOUGH TO PIN DOWN WITH THE LATEST
MODELS GENERALLY INITIALIZING TOO FAR NORTH WITH SIGNIFICANT
PRECIPITATION. THE CANADIAN MODEL SEEMED TO INITIALIZE BETTER THAN
THE GFS OR ECMWF. THE SPC SSEO FORECAST FROM YESTERDAY MORNING
SEEMED TO HAVE A GOOD HANDLE ON THE TRACK OF THE REMNANT MOISTURE
OVERNIGHT...SO WE LEANED TOWARD THAT PROGNOSIS WITH THE POP
FORECAST THE NEXT COUPLE DAYS.

NOT MUCH CHANGE TO THE FORECAST IN THE WAKE OF ODILES
REMNANTS...WITH THE UPPER LOW SHIFTING NORTHEASTWARD FROM THE CA
COAST ACROSS THE CENTRAL ROCKIES. THIS SYSTEM WILL STILL DRAW A
BACK DOOR COLD FRONT THROUGH NM LATE FRIDAY NIGHT AND
SATURDAY...WITH A MODESTLY GUSTY E CANYON WIND IN THE RIO GRANDE
VALLEY SATURDAY NIGHT. THUNDERSTORM CHANCES SUNDAY SHOULD FAVOR
THE SOUTHERN AND WESTERN TIER OF ZONES...AS WELL AS THE MOUNTAINS.
THEN THE MONSOON MOISTURE PLUME SHOULD MOVE MORE SQUARELY OVER NM
ON MONDAY FAVORING THE CONTINENTAL DIVIDE TO THE E SLOPES OF THE
CENTRAL MOUNTAIN CHAIN FOR THE BEST PRECIPITATION CHANCES.
LOCATIONS ALONG AND E OF THE CENTRAL MOUNTAIN CHAIN SHOULD BE
FAVORED TUESDAY AS THE SYSTEM EXITING THE CENTRAL ROCKIES SHIFTS
THE MONSOON MOISTURE PLUME FARTHER EAST.

.FIRE WEATHER...
NO SIGNIFICANT FIRE WEATHER CONCERNS EXPECTED
THROUGH THE FORECAST PERIOD. ODILE REMNANTS WILL CONTINUE MOVING
SLOWLY TO THE ENE THROUGH THE DAY TODAY. MOST AREAS SOUTH OF
INTERSTATE 40 WILL SEE WETTING RAINS...BUT THE FLASH FLOOD THREAT
WILL BE HIGHEST ACROSS PORTIONS OF SOUTH CENTRAL AND EASTERN NM.
AS ODILE BEGINS TO EXIT THE STATE FRIDAY...THE FOCUS WILL BE
PRIMARILY ACROSS THE NORTHERN MOUNTAINS AND THE EASTERN
PLAINS...THOUGH AFTN SHOWERS AND THUNDERSTORMS WITH WETTING RAINS
WILL BE POSSIBLE ACROSS THE WESTERN HIGH TERRAIN. OCCASIONAL
AFTERNOON GUSTS ARE POSSIBLE TODAY ACROSS THE SANGRE DE CRISTO MTS
AND THE FAR NORTHEAST PLAINS FRIDAY....OTHERWISE WINDS WILL
GENERALLY BE LIGHT TODAY AND FRIDAY. HIGH TEMPERATURES TODAY WILL
CHANGE LITTLE FROM YESTERDAYS READINGS...REMAINING WELL BELOW
NORMAL SOUTH OF INTERSTATE 40 AND NEAR TO BELOW NORMAL NORTH OF
THE INTERSTATE. WEAK WARMING WILL BEGIN ACROSS THE WEST
FRIDAY...WHERE HIGHS WILL BECOME NEAR NORMAL...WHILE BELOW NORMAL
VALUES PERSIST EAST OF THE CENTRAL MOUNTAINS. SLIGHTLY BETTER VENT
RATES TODAY WILL BECOME FAIR TO POOR MOST AREAS FRIDAY.

AS ODILE EXITS WHILE BEING ABSORBED INTO AN UPPER LEVEL 
TROUGH...MODELS POINT TO A BACKDOOR COLD FRONT ENTERING THE EASTERN 
PLAINS SATURDAY MORNING. THE NAM AND GFS MODELS GENERALLY AGREE THAT
STRONG WINDS AND A DECENT MOISTURE SURGE WILL ACCOMPANY THIS 
FRONT...BUT THE ECMWF MODEL IS LESS BULLISH. THIS COULD IMPACT 
OVERALL CONVECTIVE ACTIVITY SATURDAY AND SUNDAY...BUT CURRENT 
THOUGHT ALIGNS WITH BULLISH GFS/NAM. GAP WINDS WILL DEVELOP DURING 
THE MORNING HOURS SATURDAY AND PERSIST THROUGH THE DAY. AFTERNOON 
SHOWERS AND THUNDERSTORMS WILL DEVELOP EACH DAY PRIMARILY OVER THE 
HIGHER TERRAIN. NEAR TO ABOVE NORMAL TEMPERATURES SATURDAY WILL DROP 
CLOSER TO NEAR NORMAL SUNDAY AFTER THE FRONTAL PASSAGE. VENT RATES 
WILL IMPROVE EACH DAY...THOUGH POCKETS OF FAIR TO POOR VALUES WILL 
REMAIN POSSIBLE.

MODELS ARE IN DECENT AGREEMENT ON A WEAK RIDGE BREAKDOWN AS A CLOSED 
UPPER LEVEL LOW ROUNDS THE RIDGE LATE SUNDAY THROUGH EARLY NEXT 
WEEK. THIS WILL HELP PROVIDE A FOCUS FOR THUNDERSTORM ACTIVE ACROSS 
NORTHERN NM...BUT LITTLE ELSE IS EXPECTED. NO SIGNIFICANT WIND 
INCREASES OR DRY SLOTS WILL ACCOMPANY THIS FEATURE. THAT SAID...A 
WEAK DRYING AND WARMING TREND WILL BEGIN MONDAY THROUGH MID NEXT 
WEEK...ESPECIALLY ACROSS WESTERN NM. MODELS HINT AT A SIGNIFICANT 
TROUGH SYSTEM FOR THE LATE WEEK/WEEKEND PERIOD...BUT THEY REMAIN 
INCONSISTENT RUN TO RUN AND MODEL TO MODEL TO PUT ANY STOCK IN IT.
