.PREV DISCUSSION...241 PM MDT SAT AUG 10 2013...
CURRENTLY...ACTIVE CONVECTION KICKING OFF IN STYLE THIS
AFTERNOON...WITH COVERAGE WEST AND NORTH EXPANDING EAST AND SOUTH
THROUGH THE DAY. LOCALLY HEAVY RAIN STILL ON TAP FOR THE HEART OF
NORTHERN AND CENTRAL NEW MEXICO WITH FLASH FLOOD WATCH OUT THROUGH
EARLY SUNDAY MORNING TO COVER. UPPER AIR CHARTS DEPICTING RIDGE
CORE OVER THE X IN TEXAS WITH DOME OF SURFACE HIGH PRESSURE
SPRAWLED ACROSS THE STATE IN OTHERWISE VERY WEAK SURFACE PRESSURE
GRADIENT. PATTERN WILL SET UP SLOW MOVEMENT OF THUNDERSTORMS FOR
THE BULK OF THE STATE...WITH SOMEWHAT GREATER NORTHEAST TRANSPORT
FOR STORMS OVER THE NORTHERN AND WESTERN MARGINS OF THE STATE.

MODELS...IN GOOD AGREEMENT ON BASIC STORY THROUGH UPCOMING WORK
WEEK AND FOLLOWING WEEKEND. RIDGE CORE IN SLOW DRIFT TO THE BOOT
HEEL OF SOUTHWEST NEW MEXICO THROUGH TUESDAY AND INTO THE DRAGOON
MOUNTAINS OF SOUTHEAST ARIZONA BY THURSDAY. RIDGE CORE EXPANDS
STEADILY OVER ARIZONA HEADING INTO THE WEEKEND ALLOWING NORTHWEST
FLOW TO PENETRATE THE EASTERN END OF THE STATE AND SHIFTING
CONVECTIVE FOCUS HEADING INTO THE FOLLOWING WORK WEEK.

FOR TONIGHT...TODAYS AFTERNOON CONVECTION WILL ROLL RIGHT ON
THROUGH THE EVENING AND CONTINUE LOCALLY PAST MIDNIGHT. HEAVIEST
RAINFALL FOCUS WILL SHIFT FROM THE HEART OF NEW MEXICO TO THE
SOUTH CENTRAL AND SOUTHWEST MOUNTAINS FOR THE OVERNIGHT...WITH
LOCALLY HEAVY RAINS STILL POSSIBLE. HAVE EXTENDED THE FLASH FLOOD
WATCH ALREADY TIL 6 A.M. SUNDAY MORNING...WITH SOME EXPECTATIONS
THAT NORTHERN ZONES MAY BE TRIMMED OUT OF THE WATCH AROUND
MIDNIGHT TONIGHT WHILE SOUTHERN ZONES CONTINUE TIL DAYBREAK.
TRENDS WILL DICTATE THE OUTCOME AS THE EVENING WEARS ON.

FOR SUNDAY...RIDGE CORE EXPANDING INTO WEST TEXAS AND SOUTHEAST
NEW MEXICO WITH THERMAL LOW REMAINING STRONG OVER THE COLORADO
RIVER VALLEY. SOUTH TO SOUTHEAST FLOW WILL PERSIST OVER THE
STATE...WITH MODEST REDUCTIONS IN THUNDERSTORM INTENSITY OVER THE
NORTH AND CENTRAL...AND SOME CONCENTRATION OF ACTIVITY AND
HEAVIEST RAINFALL OVER THE SOUTH AND WEST. THIS WILL NEED EVALUATION
FOR POSSIBLE FLASH FLOOD WATCH ONCE THE SATURDAY NIGHT ACTIVITY
WINDS DOWN. SHOWER FOCUS OTHERWISE IN OUR FORECAST AREA WILL FAVOR
THE CENTRAL AND WEST...WITH COVERAGE TAPERING OFF IN THE EAST AS
RIDGE CORE BUILDS IN OVERHEAD FROM THE EAST. RAINFALL WILL TAPER
OFF SLOWLY SUNDAY NIGHT HEADING INTO MONDAY MORNING WITH CHANCES
FOR A FEW LOCALLY HEAVY DOWNPOURS AFTER MIDNIGHT.

FOR MONDAY...RIDGE CORE SHIFTING WEST TO OVERSPREAD SOUTHERN NEW
MEXICO...AND THIS WILL HELP RATCHET DOWN THE CONVECTIVE COVERAGE
AND INTENSITIES. HIGH COUNTRY WEST AND CENTRAL...AND THE NORTHERN
MOUNTAINS...WILL BE MOST FAVORED WITH RAINFALL AMOUNTS STARTING TO
TREND LOWER THROUGH MONDAY EVENING. MAXIMUM TEMPERATURES WARMING
SLIGHTLY...BRINGING ALL POINTS TO WITHIN A FEW DEGREES OF MID
AUGUST NORMALS.

FOR TUESDAY...RIDGE CORE SHIFTING WESTWARD TO THE NEW MEXICO BOOT
HEEL...AND RIDGE OVERHEAD WILL PRODUCE ANOTHER DOWN TICK IN
CONVECTIVE COVERAGE AND INTENSITY. AS CORE SHIFTS WEST...SOME
PENETRATION OF UPPER LEVEL NORTHWEST FLOW...AND THE ASSOCIATED
COLD FRONT PULLING OUT OF THE CENTRAL PLAINS INTO NORTHEAST NEW
MEXICO WILL HELP SHIFT COVERAGE OUT OF THE WEST AND INTO THE
NORTHEAST. HEAVIER RAINFALL WILL FAVOR THE SUMMITS AND EASTERN
SLOPES OF THE SANGRE DE CRISTO RANGE AND THE CENTRAL MOUNTAIN
CHAIN...WITH SOME REDUCTIONS IN STORM INTENSITIES OVER THE
CONTINENTAL DIVIDE AND WESTERN MOUNTAINS. EASTERLY FLOW AGAINST
THE CENTRAL MOUNTAINS TUESDAY NIGHT MAY KICK OFF SOME GAP FLOW
INTO THE RIO GRANDE VALLEY OVERNIGHT INTO WEDNESDAY MORNING.

OUTLOOK...WEDNESDAY THROUGH FRIDAY...RIDGE CORE OVER MUCH OF
SOUTHERN NEW MEXICO WEDNESDAY SHIFTING TO SOUTHEAST ARIZONA ON
THURSDAY...AND CORE EXPANDING ACROSS EASTERN ARIZONA AND WESTERN
NEW MEXICO THROUGH FRIDAY. PATTERN WILL CONTINUE CONVECTIVE FOCUS
SHIFT OUT OF THE WEST AND INTO THE EAST ON FRIDAY...BUT WITHOUT A
SIGNIFICANT MOISTURE TAP...MOST OF THE CONVECTION WILL RECYCLE
MOISTURE ALREADY IN PLACE AS PRECIPITABLE WATERS TREND DOWNWARD.
WITH NORTHWEST FLOW ALOFT ESTABLISHED OVER NORTHEAST NEW
MEXICO...A SERIES OF ASSOCIATED COOL PULSES WILL INVADE KEEPING
THESE TEMPERATURES A LITTLE BELOW NORMAL. WARMING TRENDS ELSEWHERE
UNDER THE HEART OF THE RIDGE WILL PERMIT SOME RISES ABOVE MID
AUGUST NORMALS THROUGH THE END OF THE WORK WEEK.
