Severe Thunderstorm Warning 10, NWS El Paso, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO-SANTA TERESA NM
230 PM MDT MON JUN 16 2003

SYNOPSIS...
LOW LEVEL EASTERLY FLOW WILL KEEP IMPORTING MODERATE MOISTURE IN THE
AREA AS
THE HIGH PRESSURE ALOFT CONTINUES TO KEEP IT TRAPPED OVER THE REGION
UNTIL LATE IN THE WEEK. OVERNIGHT BREEZES WILL CONTINUE OVER AREA
WEST SLOPES. DAYTIME HEATING COMBINED WITH UPSLOPE FLOW WILL
INITIATE AFTERNOON AND EVENING THUNDERSTORMS DAILY THROUGH MUCH OF
THE WEEK. BEST THUNDERSTORM CHANCES ARE OVER THE MOUNTAINS.
TEMPERATURES WILL HOVER NEAR NORMAL...AND BE SLIGHTLY WARMER LATE
THIS WEEK.  RAIN CHANCES DIMINISH LATE IN THE WEEK.

DISCUSSION...
CURRENT SITUATION THIS AFTERNOON SHOWS ISOLATED TO SCATTERED HIGH
TERRAIN THUNDERSTORMS OVER CENTRAL AND SOUTHERN NEW MEXICO UNDER AN
UPPER LEVEL RIDGE. A DECENT LOW LEVEL...BUT RELATIVELY SHALLOW...
EAST PUSH INTO THE CWFA OVERNIGHT WILL CONTINUE TO KEEP MOISTURE
COMING FOR THE NEXT COUPLE OF DAYS. HIGH PRESSURE ALOFT IS DOING
ITS BEST TO KEEP THE AREA STABLE...BUT ITS NO MATCH FOR INTENSE
SURFACE HEATING COUPLED WITH OROGRAPHIC LIFTING. THUS THE CURRENT
ROUND OF MOUNTAIN STORMS.  AVN AND ETA BOTH INDICATE A NUMBER OF
SHORTWAVE DISTURBANCES TRACKING NORTH TO SOUTH THROUGH EASTERN NEW
MEXICO DOWN THE FRONTSIDE OF THE RIDGE. THIS WOULD HELP NOCTURNAL
AND EARLY MORNING CONVECTION AND SHOWERS...AND ALSO ENHANCE SOME
LOWLAND AFTERNOON CONVECTION...ALL DEPENDENT ON TIMING. AVN LOOKS TO
OVERDO THE VORT CENTERS/SHORTWAVES LEADING ME TO THINK IT COULD BE A
CONVECTIVE FEEDBACK ISSUE.

WILL CONTINUE THE CURRENT FORECAST OF KEEPING DAILY AFTERNOON AND
EVENING POPS IN FOR TUE AND WED...AND ADD SOME OVERNIGHT POPS EAST
OF THE RIO GRANDE. LATE WEEK LOOKS TO DRY AS THE SFC HEAT TROUGH
OVER THE BOOTHEEL ERODES AND ALLOW MORE SOUTHWESTERLY WINDS ACROSS
THE CWFA. ALSO THE UPPER RIDGE BUILDS BACK OVER AND SHIFTS EAST TO
HELP STABILIZE THE AREA.

FOR THE WEEKEND. AN UPPER LOW IS ANALYZED TO LIFT JUST NORTH OF THE
CWFA. WILL PUT SOME SAT POPS IN THE GILA BUT KEEP THE REST OF THE
AREA DRY.

SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE EL PASO TX
250 PM MDT MON JUN 16 2003

LOW LEVEL MOISTURE HAS SPREAD ACROSS MOST OF SOUTHERN NEW MEXICO AND
FAR WEST TEXAS TODAY...GIVING THE AREA A GOOD CHANCE AT SOME STRONG
THUNDERSTORMS THIS AFTERNOON AND EVENING. THE FIRST STORMS OF THE
DAY HAVE ALREADY DEVELOPED OVER THE GILA..SAN ANDRES AND SACRAMENTO
MOUNTAINS OF SOUTHERN NEW MEXICO. A FEW OF THESE STORMS HAVE ALREADY
PRODUCED HEAVY DOWNPOURS OF ONE TO ONE AND ONE-HALF INCHES IN ONE
HOUR OR LESS...ALONG WITH SOME SMALL HAIL.

NEW STORMS ARE EXPECTED TO FORM OVER THE LOWLANDS...MOSTLY EAST OF
DEMING THROUGH THIS EVENING. WITH THE SLOW MOVEMENT OF THESE
STORMS...EXPECT A FEW OF THESE STORMS TO DUMP RAINFALL OF ONE TO TWO
INCHES IN ONE HOUR OR LESS. LOCAL RAINFALL APPROACHING THREE INCHES
IS POSSIBLE DUE TO THE SLOW MOVEMENT. GUSTY WINDS OF 40 TO 50 ARE
POSSIBLE NEAR THESE STORMS.
