AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
258 PM MDT WED JUN 17 2015

.SYNOPSIS...
HIGH PRESSURE WITH WARMER AND DRIER AIR IS WORKING IN FROM THE
WEST...BUT STILL WE HAVE PLENTY OF WARM MOIST AND UNSTABLE AIR TO
THE EAST. THUS WE CONTINUE WITH POTENTIAL FOR ISOLATED TO
SCATTERED STORMS THIS EVENING...ESPECIALLY EAST OF THE CONTINENTAL
DIVIDE. TOMORROW AND EACH DAY THROUGH THE WEEKEND WE WILL SEE
LESSER CHANCES FOR RAIN AND THUNDERSTORMS AS THE HIGH PRESSURE
SLOWLY SHIFTS OVER THE BORDERLAND THIS WILL MEAN GENERALLY LIGHT
WINDS...FEWER CLOUDS...AND HOTTER TEMPERATURES. LOWLANDS SHOULD
SEE THE FIRST 100 DEGREE DAY FOR A STRING OF SEVERAL DAYS. NEXT
WEEK THE RIDGE EASES TO COOL TEMPERATURES A BIT AND ALLOW A RETURN
OF GULF MOISTURE. THUS AFTER THIS PERIOD OF HOT AND DRY WEATHER
THIS WEEK WE MAY SEE THE INITIATION OF THE 2015 MONSOON NEXT
WEEK.

&&

.DISCUSSION...
WATER VAPOR SATELLITE IMAGERY SHOWS DRYING OVER THE WESTERN ZONES
THIS AFTERNOON AS A DOMINATING RIDGE OF HIGH PRESSURE OVER THE
WEST COAST BEGINS TO EXPAND EAST ACROSS AZ AND INTO FAR SW NEW
MEXICO. WEAK WESTERLY FLOW WEST OF THE CONTINENTAL DIVIDE IS
HELPING TO LOWER MOISTURE AS EVIDENT IN DEWPOINTS DROPPING TO THE
U30S-L40S. HOWEVER THE MOISTURE REMAINS OVER AREAS EAST OF THE
DIVIDE WITH DEWPOINTS IN THE U40-M50S. RADAR BEARS THIS OUT WITH
ISOLATED TO SCATTERED STORM DEVELOPMENT OVER THE SACS AND
EXPANDING SOUTH AND WEST OVER S OTERO...EL PASO AND HUDSEPTH
COUNTIES...AND INTO DONA ANA AND SIERRA CO. WITH WARM TEMPS ALOFT
INSTABILITY IS WEAK TO MARGINAL WITH LOW CAPES AND MODERATELY
NEGATIVE LI'S...BUT STILL WITH OROGRAPHICS AND DAYTIME HEATING
MOST OF THE REGION WILL BE UNSTABLE. THUS ISOL -TSRA IN THE
EVENING FORECAST FOR MOST ZONES.

THIS TREND TOWARD DRIER CONDITIONS CONTINUES THU...FRI...SAT...SUN
AS THE UPPER RIDGE CONTINUES TO SLOWLY TRACK...EXPAND...AND
STRENGTHEN TO THE EAST. THE NORTH/NE FLOW ALOFT WILL BRING DRY
CONTINENTAL AIR OVER THE AREA. THE RIDGE EVENTUALLY CENTERS
DIRECTLY OVER CENTRAL NM ON SUN. THE PROGRESSION WILL BE DRIER AND
WARMER CONDITIONS FOR THE ENTIRE REGION. HOWEVER MODELS DO NOT
MAKE A HARD AND CLEAN SWEEP OF MOISTURE AS WIND WILL BE ON THE
LIGHT SIDE AND WE NEVER FULLY RID OUR EASTERN ZONES OF THE EAST
PUSH. THUS VERY SLIGHT STORM CHANCES FOR OTERO/HUDSPETH STORMS
EACH AFTN/EVE WITH GENERALLY DRY FORECASTS AND MOSTLY CLEAR SKIES
FOR ALL OTHER ZONES FOR THESE PERIODS. TEMPS WILL SOAR UNDER THE
SUBSIDENCE OF THE HIGH PRESSURE RIDGE WITH OUR FIRST 100 DEGREE
DAYS ACROSS THE LOWLANDS FOR THU- SUN. WITH HIGH PRESSURE
ENTRENCHED...PRESSURE GRADIENTS WILL BE LOOSE...RESULTING IN LIGHT
WINDS.

MONDAY ONWARD THE UPPER HIGH PRESSURE RIDGE BEGINS TO SHIFT EAST.
BY TUESDAY IT IS RECENTERED OVER THE GULF STATES. DURING THIS TIME
WE BEGIN TO COME UNDER A MORE SOUTH/SOUTHEASTERLY FLOW ON THE
BACKSIDE OF THE HIGH. WELL TO OUR WEST WILL BE THE PERSISTENT WARM
SEASON THERMAL LOW. THE RESULT IS A DEEP CHANNEL THAT SHOULD BEGIN
TO BRING MOISTURE BACK TO THE REGION. THIS PATTERN IS CONSISTENT
WITH THE SUMMER MONSOON ONSET WITH GULF MOISTURE MOVING WEST INTO
FAR WEST TEXAS AND SOUTHERN NEW MEXICO. THERE ARE MODEL
DIFFERENCES BEYOND TUESDAY WHERE THE GFS IS DRIER...KEEPING THE
MOISTURE A BIT EAST THANKS TO A SMALL RIDGE TO OUR WEST. THE ECMWF
POSITIONS THE MOIST PLUME OVER OUR CWFA FOR A WETTER OUTLOOK. FOR
NOW WE REINTRODUCE CHANCES FOR PCPN/STORMS WITH THIS PATTERN
SHIFT.

AN UPPER HIGH WILL BE BUILDING IN FROM THE WEST THROUGH THE WEEKEND.
THIS WILL BRING THE HOTTEST TEMPERATURES OF THE YEAR TO THE ENTIRE AREA.

DEGREES OVER THE WEEKEND. THUNDERSTORM ACTIVITY WILL BE ON THE
DECREASE AS DRIER AIR MOVES IN WITH JUST ISOLATED MOUNTAIN STORMS
EXPECTED. MINIMUM RELATIVE HUMIDITIES WILL BE FALLING INTO THE 5
TO 15 PERCENT RANGE FOR THE LOWLANDS WITH TEENS AND 20S IN THE
MOUNTAINS. WINDS WILL BE LIGHT SO CRITICAL CONDITIONS ARE NOT EXPECTED.
