Flash Flood Warning 27, NWS Albuquerque, NM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
325 AM MDT WED JUL 28 2010

.DISCUSSION...
LOCALLY HEAVY RAINS WILL CONTINUE TO BE ON THE RADAR SCOPE FOR THE
NEXT SEVERAL DAYS...ESPECIALLY ACROSS SRN/WRN NEW MEXICO. 00Z/WED
KABQ SOUNDING TOOK A DECENT HIT IN THE PRECIPITABLE WATER CATEGORY
BUT SHOULD EXPERIENCE A SLOW REBOUND AS AN UPPER LEVEL LOW MIGRATES
WESTWARD INTO THE REGION. THERE ARE SIGNIFICANT DIFFERENCES IN THE
PWAT VALUES BETWEEN THE GFS40/NAM12 WITH THE LATTER BEING MORE WET.
NONETHELESS...VALUES SHOULD REMAIN ABOVE SEASONAL NORMALS TO ALLOW
FOR HEAVY RAINFALL CAPABLE OF MINOR OR LOCALIZED FLASH FLOODING. AT
THIS TIME...CONFIDENCE IN WIDESPREAD SIGNIFICANT FLOODING IS NOT AN
ISSUE AND WILL NOT POST A WATCH AT THIS TIME.

FOR TODAY...UPPER LEVEL CYCLONE WILL START TO INVADE SE NEW MEXICO
AS THE FEATURE WEAKENS INTO AN OPEN WAVE. MEANWHILE...E/SE BOUNDARY
LAYER FLOW WILL PROVIDE AN UPSLOPE COMPONENT ACROSS A GOOD PORTION
OF THE STATE...PARTICULARLY IN THE ERN PLAINS. EXPECT AN UPTICK IN
CONVECTION IN THE SRN/SE PARTS OF THE FORECAST AREA...WHILE DIURNAL
STORMS CONTINUE OVER THE NW HALF. THE LEAST AMOUNT OF COVERAGE WILL
BE OVER THE NE PLAINS. BY LATER TONIGHT...EXPECT THE PRIMARY THREAT
FOR PCPN TO BE ALONG AND WEST OF THE CENTRAL MOUNTAIN CHAIN. HIGHS
TODAY WILL BE SLIGHTLY ABOVE/BELOW NORMAL NORTH/SOUTH OF INTERSTATE
40 RESPECTIVELY. BY THURSDAY...UPPER LEVEL DISTURBANCE SHOULD SHEAR
OUT AS IT CONTINUES A SLOW WESTWARD TRACK TOWARD CENTRAL NM. AGAIN...
THE BEST CHANCES FOR QPF WILL BE ALONG/WEST OF THE CENTRAL MT CHAIN.
THROUGH THURS AFTERNOON...THE MODELS ARE IN FAIRLY GOOD AGREEMENT.

MODELS DIVERGE NOTICEABLY FOR THE FRIDAY THROUGH WEEKEND PERIOD ON
HOW THE UPR LEVEL PATTERN WILL EVOLVE. GFS40 IS FAIRLY PROGRESSIVE
ON THE WESTWARD TRACK OF THE AFOREMENTIONED WAVE...PRIMARILY DUE TO
A WEAKER UPPER HIGH WHICH IS CURRENTLY POSITIONED IN CENTRAL CO. THE
ECMWF IS PRETTY SIMILAR...ALTHOUGH HAS A MORE NRN TRACK OF THE WAVE
THRU CENTRAL NM...LEADING TO A HIGHER THREAT FOR QPF. THEREAFTER...
BOTH OF THESE MODELS DRIFT THE WAVE NORTHWARD ON THE WRN PERIPHERY
OF THE HIGH INTO THE INCREASING WESTERLIES OVER THE CENTRAL ROCKIES.
THE PRIMARY CENTER OF CIRCULATION OF THE UPPER HIGH IS PROGGED TO BE
IN THE WRN GULF STATES...KEEPING THE DOOR OPEN FOR A MONSOONAL SURGE
FOR THE WEEKEND. IF THIS SCENARIO PANS OUT...THEN WRN NM COULD BE A
PRIME LOCATION FOR ENHANCED CONVECTIVE POTENTIAL. ON THE FLIP SIDE...
THE CANADIAN KEEPS A MORE WRN TRACK FOR THE AFOREMENTIONED WAVE WITH
A STRONG RIDGE REMAINING TO THE N/NW. BY THE WEEKEND...THE CANADIAN
THINKS THE UPPER HIGH WILL BE IN A STRONG POSITION TO BLOCK A DECENT
MONSOONAL SURGE AND EVEN SUGGESTS SIGNIFICANT DRYING ACROSS MUCH OF
MEXICO AND NM...OFFERING ONLY RECYCLE MODE FOR THE CWA. THE OVERALL
MESSAGE...STAY TUNED. NO MATTER THE CASE...THE HIGHER POPS WILL BE
FOCUSED IN WRN NM WHILE THE ERN PLAINS WILL BE FAIRLY LIMITED. IT IS
JUST UNCLEAR HOW LARGE OF A POP SPREAD THAT COULD DEVELOP ACROSS THE
FORECAST AREA. DPORTER

.AVIATION...
LOCALIZED MVFR CIGS AND MT OBSCURATIONS IN A FEW SPOTS NEAR TO WEST
OF THE DIVIDE AND PERHAPS FAR E CENTRAL NM EARLY TO MID MORNING...
BUT OVERALL A VFR MORNING. SHOWER AND THUNDERSTORM ACTIVITY SHOULD
INCREASE AT LEAST A BIT ACROSS S AND E PORTIONS OF FCST AREA THIS
AFTN AND EVE...PERHAPS ACROSS CENTRAL SECTIONS AS WELL...AS TX UPPER
LOW ENTERS OR GETS VERY NEAR THE SE OR E CENTRAL PORTION OF THE
STATE. BRIEF AND LOCALIZED MVFR CONDITIONS IN CIGS AND PCPN REDUCED
VSBYS ASSOCIATED WITH STORMS TODAY. POTENTIAL INCREASES VERY LATE
TONIGHT AND EARLY THU FOR SOME AREAS OF MVFR AND MORE LOCALIZED IFR
CIGS ACROSS SOUTHERN AND E CENTRAL PORTIONS OF FCST AREA WITH TAF
SITES KTCC AND KROW HAVING A LITTLE BETTER CHANCE OF THOSE LOWER
CIGS THAN OTHER SITES.

NEXT AVIATION DISCUSSION SCHEDULED FOR 21Z. 43

&&

.FIRE WEATHER...
OVERALL HIGHER HUMIDITY PATTERN LINGERING THROUGH REST OF THE WEEK
AND FAIRLY LIKELY FOR THE WEEKEND. WETTING THUNDERSTORM COVERAGE
SHOULD INCREASE SOMEWHAT ACROSS MAINLY SE HALF OF NM THIS AFTN AND
EVE AS TX UPPER LOW GETS VERY NEAR OR EVEN ENTERS FAR E CENTRAL OR
SE NM LATE TODAY. ELSEWHERE MOISTURE RECYCLING WILL GENERATE AT
LEAST ISOLATED TO WIDELY SCATTERED THUNDERSTORMS...FAVORING THE
HIGHER TERRAIN.

THE MID LEVEL HIGH IS STILL EXPECTED TO BE FOCUSED TO THE EAST OF
THE STATE FRI THROUGH SUN...BUT A QUICK LOOK AT LATEST...06Z RUN...
SHORTER TERM NAM MODEL BEGINNING TO CONTRADICT THIS SCENARIO BY
KEEPING UPPER HIGH CENTERED FRI AND SAT AT LEAST NOT FAR FROM 4
CORNERS. THIS SCENARIO...IF IT PANS OUT...WOULD MEAN LESS WETTING
RAIN COVERAGE ACROSS AT LEAST N NM FROM WEEKEND INTO AT LEAST A
PORTION OF NEXT WEEK. THUS CONFIDENCE OF INCREASED WETTING RAINS FOR
THAT PERIOD ACROSS N AREAS BEGINNING TO WANE A BIT. LATER MULTIPLE
MODEL RUNS CONSENSUS WILL HAVE TO BE WATCHED TO SEE IF THIS BECOMES
A TREND. FOR THIS FCST PACKAGE WILL STILL GO WITH SOME INCREASE IN
MONSOONAL MOISTURE ACROSS W NM FOR LATE WEEK AND INTO WEEKEND...BUT
NORTHERN AREAS MAY NOT GET AS MUCH BENEFIT AS EARLIER THOUGHT IF NEW
MODEL RUNS CONTINUE THE LATEST NAM TREND. AFTER THU OR FRI EASTERN
AREAS SHOULD HAVE LEAST AMOUNT OF WETTING RAIN POTENTIAL. EMBEDDED
TROPICAL AND CONVECTIVELY INDUCED WAVES WILL ALSO PROVIDE A WILDCARD
TO DAILY COVERAGE CHANGES.

HIGH TEMPERATURES SHOULD REMAIN SLIGHTLY TO MODERATELY BELOW NORMAL
FAVORING SOUTHERN AND WESTERN AREAS AND NEAR TO SLIGHTLY ABOVE
NORMAL NORTH AND EAST CENTRAL. OVERNIGHT LOW TEMPERATURES SHOULD
OVERALL BE SLIGHTLY ABOVE NORMAL DUE TO THE HIGHER HUMIDITY AT THE
SURFACE. MINIMUM HUMIDITY VALUES ARE NOT FORECASTED TO DROP BELOW 20
PERCENT FOR THE FORESEEABLE FUTURE...ESPECIALLY ACROSS W AND S
SECTIONS OF FCST AREA. GOOD TO EXCELLENT OVERNIGHT HUMIDITY
RECOVERIES EXPECTED TONIGHT MAJORITY OF N AND CENTRAL NM WITH
COVERAGE OF SAME POSSIBLY INCREASING SOMEWHAT THE FOLLOWING 2 TO 3
NIGHTS.

NEAR SURFACE WIND SPEEDS GENERALLY TO BE 12 MPH OR LESS WELL OUTSIDE
OF STORMS. THUNDERSTORM OUTFLOW WINDS WILL CONTINUE TO PROVIDE THE
STRONGEST WIND FLOWS AT THE SURFACE. WEAK TO MODERATE GAP WINDS
ALONG THE CENTRAL MOUNTAINS ARE EXPECTED TO DEVELOP THIS EVE. 43
