Hail and Damaging Winds in New Mexico, June 19, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
119 PM MDT WED JUN 19 2013

.UPDATE...
SHARPENING DRYLINE OCCURRING OVER THE EASTERN PLAINS AS LOW LEVEL
MOIST EASTERLY FLOW IS MUCH STRONGER THAN MODEL GUIDANCE SHOWED
FROM YESTERDAY. THIS WILL LEAD TO SOME STRONG TO LOCALLY SEVERE
CONVECTION OVER THE FAR EASTERN COUNTIES WHERE SPC SLIGHT RISK HAS
EXPANDED TO LINE UP WITH DEVELOPING CONVECTION AND VERY STRONG
INSTABILITY. ALL THAT NEEDS TO HAPPEN NOW IS LIFT WHICH IS SHOWN
BY THE 16Z HRRR TO OCCUR BETWEEN 20Z AND 21Z. UPDATED TO RAISE
POPS AND INCLUDE SEVERE WORDING ALONG THE TX STATE LINE.

.AVIATION...
18Z TAF CYCLE
MAIN AVIATION THREATS TODAY WILL BE FOUND ALONG THE DRYLINE WHICH
IS EXPECTED TO BE FOUND ACROSS THE EASTERN PLAINS. STORMS SHOULD
FIRE UP ALONG THIS BOUNDARY AND THEN MOVE TOWARDS THE NORTHEAST.
ROW AND TCC HAVE THE BEST CHANCE OF STORM IMPACTS. WIND IS A BIG
THREAT AND HAVE INCLUDED BLOWING DUST AT ROW. CANT RULE OUT A
DRIER SHOWER AND WIND IMPACTING LVS BUT MORE POTENTIAL SOUTH AND
EAST. TURBULENT MIXING AND MODERATE TO STRONG WINDS WILL BE FOUND
ELSEWHERE THROUGH EARLY EVENING. SIMILAR SCENARIO FOR THURSDAY
ALTHOUGH THERE IS SOME POTENTIAL FOR THE DRYLINE TO BE SHUNTED A
LITTLE FURTHER WEST BUT NOT BY MUCH.

.PREV DISCUSSION...318 AM MDT WED JUN 19 2013...
THE LATEST WATER VAPOR SATELLITE IMAGERY SHOWS THE PACIFIC DRY
SLOT OVER SOCAL...AZ AND NW MEXICO POISED TO PUNCH INTO OUR AREA
TODAY AS AN UPPER LEVEL LOW/TROUGH TRANSITIONS FURTHER INLAND
ACROSS THE PACIFIC NW. VERY DRY AIR IS ALREADY PUSHING INTO
WESTERN PORTIONS OF THE AREA WHERE DEWPOINT 24HR CHANGE VALUES ARE
AN AVERAGE -10...WITH THE LATEST OBSERVED VALUES IN THE SINGLE
DIGITS AND LOW TEENS. THIS VERY DRY AIRMASS IS CONTRASTED WITH
DEWPOINT TEMPS IN THE 50S TO NEAR 60 EAST OF THE CENTRAL MOUNTAIN
CHAIN WHERE GULF MOISTURE WILL LINGER FOR MUCH OF THE DAY AND ACT
AS FUEL FOR SHOWERS AND THUNDERSTORMS BY AFTERNOON. THE DRY SLOT
IS FORECAST TO PUSH EAST TODAY...WITH LOW LAYER MOISTURE ACROSS
CENTRAL AREAS MIXING-OUT QUICKLY AND A DRY LINE SHARPENING UP
ACROSS THE HIGHLANDS AND EASTERN PLAINS. AFTERNOON AND EVENING
CONVECTION IS ANTICIPATED...ALTHOUGH ISOLATED...ALONG AND EAST OF
THE DRY LINE. 00Z NAM12 FORECAST SBCAPE OF 3000-3500 J/KG WITH
0-6KM BULK SHEAR OF 35-45KTS...INDICATING AN ATMOSPHERE CAPABLE OF
SUPPORTING SUPERCELLS. CRITICAL FIRE WEATHER CONDITIONS ARE
FORECAST WEST OF THE DRYLINE...PUSHING INTO THE EASTERN PLAINS
LATE IN THE DAY (SEE DETAILS IN FIRE WX DISCUSSION BELOW). BREEZY
TO LOCALLY WINDY CONDITIONS ARE EXPECTED AREAWIDE THIS AFTERNOON
AND EVENING...ESPECIALLY WEST OF THE DRY LINE WITH DEEP LAYER
MIXING FORECAST. SOME BLOWING DUST IS POSSIBLE BY LATE AFTERNOON
...BUT HARD TO SAY WHERE WITH WIND SPEEDS PERHAPS JUST SHY OF
LOWER THRESHOLDS. THE NORTHWEST PLATEAU AND THE ABQ WEST MESA LOOK
TO HAVE THE BEST SHOT...BUT VISIBILITIES LIKELY TO STAY AT 6 MILES
OR HIGHER.

MORE CRITICAL FIRE WEATHER CONDITIONS POSSIBLE THURSDAY FOR MUCH
OF THE NORTH AND WEST AS THE DRY SLOT PERSISTS OVER THE AREA.
CHANCES FOR SHOWERS AND THUNDERSTORMS ON THURSDAY WILL BE CONFINED
TO THE SOUTH CENTRAL MOUNTAINS AND THE SOUTHEAST PLAINS WHERE
MOISTURE WILL LINGER...BUT MID LEVEL WARMING WILL LIMIT THE
AVAILABLE POTENTIAL ENERGY AND WETTING RAINS WILL BE HARDER TO
COME-BY. SW FLOW ALOFT TO PERSIST THROUGH THE WEEKEND AS THE
PACIFIC UPPER LOW MAKES SLOW EASTWARD PROGRESS ACROSS THE NORTHERN
ROCKIES AND THE UPPER HIGH BECOMES ESTABLISHED OVER WEST TEXAS.
THE GFS CONTINUES TO SHOW MOISTURE ROUNDING THE PERIPHERY OF THE
UPPER HIGH AND LAYING-OVER MUCH OF SOUTHERN AND EASTERN NEW
MEXICO WITH DRY AIR PERSISTING ACROSS MUCH OF THE NORTH. POPS HAVE
BEEN CONFINED MORE TO THE EAST AND SOUTH WITH THE LATEST MODEL
RUNS NOT SO ENCOURAGING FOR PRECIP HERE IN THE ABQ METRO. THE
MODELS CONTINUE TO SHOW THE UPPER HIGH DRIFTING NORTH ACROSS NM AND
BECOMING ANCHORED OVER COLORADO BY THE MIDDLE OF NEXT WEEK WITH
DEEP EASTERLY FLOW PREVAILING ACROSS NM. HOWEVER...THE DOMINANT
UPPER HIGH LOOKS TO KEEP TROPICAL MOISTURE WELL SOUTH OF THE
FORECAST AREA.

NO BIG CHANGES TO FORECAST TEMPS THIS CYCLE WITH ABOVE NORMAL
HIGHS AND LOWS PERSISTING THROUGH THE NEXT 7 DAYS.

.FIRE WEATHER...
...CRITICAL FIRE WEATHER CONDITIONS MOST AREAS EXCEPT EXTREME
EASTERN PLAINS TODAY AND THURSDAY.  CRITICAL CONDITIONS TO CONTINUE
WESTERN HIGH TERRAIN AND NORTHEAST HIGHLANDS THROUGH THE WEEKEND...

FEW CHANGES MADE TO FORECAST PACKAGE IN THE SHORT TERM. POTENT UPPER
LEVEL LOW MOVING NEARING THE PACIFIC NORTHWEST COAST WITH RELATIVELY
STRONG JET AND DRY SLOT AT THE BASE OF THE TROUGH. SECOND JET MAX
AND BROADER AREA OF DRY AIR STRETCHED ACROSS ARIZONA AND INTO NW NEW
MEXICO. CIRA LAYERED PW PRODUCT DEPICTS VERY DRY AIR AT BOTH 850 TO
700MB AND 700 TO 500 MB LAYERS. AS THE PACIFIC TROUGH APPROACHES...
THE UPPER RIDGE HAS MOVED TO THE EAST AND WEAKEN A BIT. MODELS
INDICATE DEEPER MIXING TODAY AND SOUTHWEST WINDS WILL STRENGTHEN
STEADILY...ESPECIALLY OVER HIGHER TERRAIN.  THUS...CRITICAL FIRE
WEATHER CONDITIONS EXPECTED TO DEVELOP BY MID DAY AND EXPAND IN
COVERAGE THROUGH THE AFTERNOON. SUPER HAINES PROBABLE ACROSS WESTERN
ZONES. WITH PERSISTENT MOIST SOUTH TO SOUTHEAST FLOW INTO THE
EASTERN PLAINS...MINIMUM RH VALUES ARE EXPECTED TO REMAIN ABOVE 15
PERCENT WITH ISOLATED THUNDERSTORMS. SOME OF THESE STORMS COULD BE
OF THE DRY VARIETY GENERALLY ALONG THE NORTHEAST AND CENTRAL
HIGHLANDS. OVERNIGHT RH RECOVERIES TO BE POOR WESTERN AND CENTRAL
ZONES.

SIMILAR SITUATION ON THURSDAY AS HEIGHTS CONTINUE TO DECREASE AND
THE GRADIENT STRENGTHENS A BIT OVER THE STATE.  UPPER LEVEL HIGH
CENTERED OVER WEST TEXAS WITH MOIST SOUTHERLY LOW LEVEL FLOW EXTREME
EAST. WILL LEAVE FIRE WEATHER WATCH IN PLACE...BUT DECREASED
DEWPOINTS ALL LOCATIONS...INCLUDING THE EAST SUCH THAT THE WESTERN
PORTIONS OF ZONES 104 AND 108 LOOK TO REACH CRITICAL CRITERIA AND
MAY NEED TO BE ADDED. SUPER HAINES ONCE AGAIN ACROSS WESTERN ZONES
AND NORTH CENTRAL ZONES AS WELL.

UPPER HIGH TO REMAIN OVER WEST TEXAS FRIDAY THROUGH SUNDAY.
PREVIOUSLY...EXTENDED MODELS DEPICTED A NORTHWARD FLUX OF MOISTURE
OVER THE STATE SUPPORTING SLIGHT CHANCES OF WETTING RAIN CENTRAL AND
EASTERN ZONES. HOWEVER...LATEST GFS IS DRIER WITH CONTINUED
SOUTHWEST FLOW AND MOIST RETURN FLOW LIMITED TO THE SOUTHEAST AND
EXTREME EAST CENTRAL PLAINS. THUS DEWPOINTS AND POPS WERE TRIMMED
BACK ACROSS THE NORTHWEST AND CENTRAL ZONES WITH SLIGHT CHANCES FOR
WETTING RAIN REMAINING SOUTH AND SOUTHEAST ZONES. LIMITED AREAS OF
CRITICAL FIRE WEATHER CONDITIONS...MAINLY WESTERN HIGH TERRAIN AND
NORTHEAST HIGHLANDS... WITH SUPER HAINES WEST AND NORTH ARE POSSIBLE
EACH DAY.

EXTENDED MODELS BUILD THE UPPER HIGH OVER NEW MEXICO BY MID WEEK...
WITH VERY DRY CONDITIONS PERSISTING BUT LIGHTER WINDS.
