.AVIATION...
00Z TAF CYCLE
CONVECTION OCCURRING OVER WRN NM AND MOVING TOWARD THE RGV ATTM.
THIS IS EXPECTED TO DIMINISH AFT 03Z ALTHOUGH EASTERLY LOW LEVEL
WINDS ARE ANTICIPATED TO PUSH INTO THE RGV AND WWD AFT SUNSET.
SOME OF THE EXISTING STORMS TO PRODUCE LOCALIZED MVFR CIGS/VSBYS AND
SFC WND GUSTS TO 40KT. FROM THE CENTRAL MT CHAIN TO THE TX BORDER
ISOLD CONVECTION WILL BE MOST LIKELY NEAR THE MTS...WITH AREAS TO
WIDESPREAD MVFR CIGS OBSCURING HIGHER TERRAIN AND PERSISTING
THROUGH 12Z SATURDAY.

.PREV DISCUSSION...232 PM MDT FRI SEP 20 2013...
OVERNIGHT BACK DOOR FRONT MADE IT MORE OR LESS TO THE CONTINENTAL
DIVIDE EARLIER THIS MORN. AND IT IS IS GENERALLY ALONG AND NEAR IT
THAT SHOWERS AND THUNDERSTORMS HAVE DEVELOPED FROM VERY LATE MORN
ON. THE NORTHERN GILA REGION HAS...AS OF THIS WRITING...THE MOST
NUMEROUS SHOWERS AND STORMS SO FAR AND THAT WILL LIKELY REMAIN THE
CASE MOST OF THE REST OF THE AFTN AND PERHAPS EVEN INTO THIS EVE.
AWARE THAT NEIGHBORS TO THE SOUTH HAVE FLASH FLOOD WATCH OUT FOR
SOUTHERN GILA AND WILL CONSIDER SAME FOR NORTHERN GILA...BUT WILL
MONITOR RADAR TRENDS FOR POSSIBLE ISSUANCE BY OR BEFORE 21Z. STILL
BELIEVE MOISTURE WILL BE A LITTLE DEEPER OVERALL JUST S AND SE OF
OUR SECTION OF THE GILA. ACTIVITY WILL DIMINISH ALL AREAS LATER
THIS EVE AND OVERNIGHT WITH VERY LITTLE OR NOTHING OF SIGNIFICANCE
EXPECTED AFTER 08Z OR 09Z SAT.

FOR THE WEEKEND NM WILL BE COMING MORE AND MORE UNDER THE
INFLUENCE OF THE FIRST MAJOR AUTUMNLIKE TROUGH OF THE SEASON THAT
BY MONDAY WILL SCOUR THE RESIDUAL MOISTURE OUT OF THE FCST AREA.
BUT AHEAD OF IT WILL BE A COUPLE WAVES OF SHOWERS AND STORMS THAT
WILL MAINLY IMPACT MAINLY THE NW THIRD OF THE STATE...THE FIRST
LATER SAT AND THE SECOND...PERHAPS MORE FOCUSED...ONE SUN AFTN AND
EVE. WITH MUCH STRONGER DYNAMIC FORCING AND COLDER AIR ALOFT...
ALONG WITH MUCH STRONGER WINDS ALOFT...SOME OF THESE STORMS WILL
LIKELY BE HAIL AND STRONG WIND PRODUCERS...BUT THEY WILL BE MOVING
RAPIDLY AND TRAINING CELLS DO NOT SEEM TOO LIKELY FOR THE MOST
PART...SO FLASH FLOOD RISK SHOULD NOT BE TERRIBLY ELEVATED WITH
THIS ACTIVITY. PLUS THERE HAS BEEN SOMEWHAT OF A DRYING PERIOD...
ALBEIT NOT FOR VERY LONG YET...ACROSS GOOD PORTION OF THE NW
THIRD. ALSO THIS SYSTEM WILL BRING OUR FIRST PRESSURE GRADIENT
DRIVEN BREEZY TO WINDY PERIOD OF THE FALL SEASON FOR MOST OF FCST
AREA. THEN IT WILL BE DRY ALL AREAS...YES ALL AREAS...STARTING MON
AND FOR ALL OR NEARLY ALL OF NEXT WEEK. MUCH LOWER DEWPOINTS WILL
ALLOW FOR SOME POTENTIAL OVERNIGHT FREEZES FOR AT LEAST SOME OF
THE NORTHERN MOUNTAIN VALLEYS BY MON NIGHT. WINDS LIGHTER EARLY
WEEK...BUT MAY PICK UP AGAIN LATER IN THE WEEK.

.FIRE WEATHER...
THE MAIN FOCUS FOR SOME WETTING SHOWERS AND THUNDERSTORMS WILL BE
FOUND ALONG THE CONTINENTAL DIVIDE ACROSS THE WEST THE REST OF THE
DAY. CANT RULE OUT A FEW BUILDUPS OVER THE NORTH CENTRAL MOUNTAINS
AS WELL. STEERING FLOW WILL REMAIN SLOW BUT THERE IS A POSSIBILITY
OF A FEW CELLS GETTING OVER THE RIO GRANDE VALLEY. THE EASTERN PLAINS
WILL REMAIN TOO STABLE WITH ABUNDANT CLOUD COVER AND COOLER THAN
NORMAL TEMPERATURES.

THE BACK DOOR FRONT WILL MAKE ANOTHER PUSH WESTWARD OVERNIGHT.
HUMIDITY RECOVERIES ACROSS THE MAJORITY OF THE AREA WILL BE
EXCELLENT. THIS WILL PROVIDE COOLER TEMPERATURES ACROSS THE WEST ON
SATURDAY ALTHOUGH EASTERN AREAS WILL SEE WARMER CONDITIONS. HIGH
TEMPERATURES OVERALL ON SATURDAY WILL BE NEAR NORMAL. HUMIDITY
VALUES WILL BE ABOVE SEASONABLE VALUES DUE TO THE HIGHER DEWPOINTS.
VENTILATION SHOULD IMPROVE SOME MOST AREAS AND THE TRANSPORT WINDS
WILL BE MORE SOUTH/SOUTHWEST.

THE RIDGE THAT IS CURRENTLY IN PLACE OVER THE SOUTHERN ROCKIES WILL GET
NUDGED EASTWARD LATER SATURDAY INTO SATURDAY NIGHT. THIS WILL SET
THE STAGE FOR INCREASED WIND ACROSS THE ENTIRE FORECAST AREA ON
SUNDAY. MODELS REMAIN PRETTY ROBUST IN THEIR DEPICTION OF THE STRONG
LEE TROUGH ACROSS THE PLAINS AND MODERATE TO STRONG WINDS ALOFT.
DECIDED TO BUMP UP WIND SPEEDS WITHIN THE GRIDDED FORECAST AND WENT
MORE IN LINE WITH THE GFS GUIDANCE NUMBERS. THE ATMOSPHERE LOOKS TO
BE MODERATELY UNSTABLE AND NORTHERN AREAS WILL SEE SOME CLOUD COVER
THUS MITIGATING THE FULL POTENTIAL FOR THE WIND TO MIX DOWN. EITHER
WAY...WINDS WILL BE NOTICEABLE AND MARK AN OVERALL CHANGE DURING
THIS FALL TRANSITION PERIOD. WETTING PRECIPITATION WILL BE
DISTINCTLY POSSIBLE ACROSS THE NORTHWEST HALF TO TWO THIRDS. BOTH
THE ECMWF AND GFS ARE BULLISH WITH THIS SCENARIO. VENTILATION WILL
ALSO BE EXCELLENT MOST AREAS.

WEATHER MODELS ALSO SHOW TWO AREAS OF STRONG MID LEVEL DRYING ON
SUNDAY. ONE OVER THE TEXAS STATE LINE AND ANOTHER OVER THE AZ STATE
LINE. ALTHOUGH CRITICAL FIRE WEATHER GROWTH CONDITIONS ARE NOT IN
THE CARDS...THE WESTERN DRY SLOT WILL PROVIDE THE FIRST DECENT
FREEZE OF THE SEASON ACROSS THE NORTHERN AND PERHAPS WESTERN
MOUNTAINS AS SKIES CLEAR SUNDAY NIGHT. THIS DRIER AIRMASS WILL
INFILTRATE THE ENTIRE FORECAST AREA ON MONDAY....SETTING THE STAGE
FOR A POTENTIALLY STRONGER FREEZE EVENT ACROSS THE MOUNTAINS MONDAY
NIGHT. WIND SPEEDS WILL BE LESS ON MONDAY ALTHOUGH A FEW BREEZES
WILL BE FELT TO THE LEE OF THE CENTRAL MOUNTAINS. AS A RESULT OF THE
DRIER AIR MASS...MINIMUM HUMIDITY VALUES WILL FALL INTO THE MID
TEENS TO MID 20S MONDAY. VENTILATION WILL BE DECENT ENOUGH MOST
AREAS BUT SOME POOR RATINGS ARE SHOWING UP WITHIN THE GRIDDED
FORECAST.

MODELS CONTINUE TO SHOW THE SECOND PACIFIC TROUGH PUNCHING INTO THE
WESTERN US ON TUESDAY. THE WINDS ALOFT WOULD INCREASE BOTH ALOFT AND
AT THE SURFACE. DRIER AIR WOULD REMAIN IN PLACE BASED ON THE LATEST
MODEL RUN. VENTILATION SHOULD BE PRETTY GOOD WITHIN CONTINUED
MINIMUM HUMIDITIES IN THE TEENS AND 20S.

THE LONG RANGE MODELS ARE LEANING TOWARDS A DRIER AND BREEZY TO
WINDY PERIOD WEDNESDAY THROUGH FRIDAY. MONSOONAL MOISTURE FROM
MEXICO WOULD REMAIN SOUTH OF THE FORECAST AREA AND VENTILATION RATES
WOULD BE GOOD TO EXCELLENT. THE DRY SLOT WOULD MOST LIKELY REMAIN
OVERHEAD KEEPING HUMIDITY READINGS AT LEAST SEASONABLE LEVELS.
