DISCUSSION
CURRENTLY...ACTIVE CONVECTION ONGOING STATEWIDE...WITH LOCALLY
HEAVY RAINFALL OVER THE JEMEZ MOUNTAINS EARLY THIS AFTERNOON.
THUNDERSTORM COVERAGE NOW EXPANDING RAPIDLY OVER THE NORTHERN
MOUNTAINS AND THE SANGRE DE CRISTOS...WITH MORE DEVELOPMENT OVER
THE CONTINENTAL DIVIDE AND SACRAMENTO AND GUADALUPE MOUNTAINS.
SPC CONTINUING SLIGHT RISK OF SEVERE THUNDERSTORMS BROADLY NORTH
AND EAST OF A LINE FROM RATON TO TUCUMCARI. ON THE CHARTS...BROAD
RIDGE EXTENDS ACROSS THE SOUTHERN U.S. DOWNSTAIRS...COLD FRONT
SAGGING SOUTHWARD ACROSS THE EASTERN PLAINS HAS REACHED A SOCORRO
TO ROSWELL LINE...WITH WIND SHIFTS TO THE EAST AND NORTHEAST NORTH
OF THE FRONT PROVIDING SOME UPSLOPE HELP FOR THUNDERSTORM
DEVELOPMENT ALONG THE CENTRAL MOUNTAIN CHAIN.
MODELS...REASONABLE CONSENSUS AND PLAUSIBLE SOLUTION MAINTAINS
BROAD ZONAL RIDGE ACROSS NEW MEXICO THROUGH MIDWEEK...WITH TROUGH
DIGGING SOUTHWARD DOWN THE MISSISSIPPI VALLEY VEERING FLOW ALOFT
TO NORTHWEST OVER NEW MEXICO AS THE WORK WEEK GETS UNDERWAY. BY
MIDWEEK...RIDGE CORE DEVELOPING OVER THE TROPICAL EAST PACIFIC
WILL EXPAND EASTWARD ACROSS NEW MEXICO AND PUT BRAKES ON NORTHWARD
MOISTURE SURGE. RIDGE CORE CENTERED OVER NEW MEXICO FOR LATE IN
THE WORK WEEK NOW APPEARS TO REMAIN IN PLACE THROUGH THE UPCOMING
WEEKEND FOR WARM UP...AND AFTERNOON THUNDERSTORMS WORKING WITH
RECYCLED MOISTURE INITIATING ON SLOPES AND MOVING SLOWLY TO
VALLEYS THROUGH THE UPCOMING WORK WEEK.
SHORT TERM...TONIGHT THROUGH TUESDAY...COLD FRONT STALLING OVER
SOUTHERN NEW MEXICO WITH WIND SHIFT TO THE EAST PROVIDING
CONTINUED UPSLOPE ENHANCEMENT FOR THUNDERSTORM DEVELOPMENT INTO
THE EVENING...WITH THUNDERSTORM COVERAGE EXPANDING TO THE
NORTHEAST PLAINS THIS EVENING. SOME OF THESE STORMS COULD TURN
SEVERE...WITH DOWNBURST WINDS AND HAIL PUSHING INTO LARGER SIZES BY
LATE AFTERNOON. ELSEWHERE...LACK OF STEERING FLOW ALOFT WILL
ALLOW THUNDERSTORMS TO LINGER AND EXPAND OVER INITIATION
POINTS...AND WILL EXPECT A BUSY NIGHT FOR THE HYDROLOGY DEPARTMENT
OVERNIGHT.
INTO SUNDAY...ANOTHER CONVECTIVELY ACTIVE DAY ON TAP...WITH SLIGHT
RISK CONTINUING FOR SEVERE WEATHER IN NORTHEAST NEW MEXICO IN ZONE
OF MAXIMUM LOW LEVEL MOISTURE CONVERGENCE WITH CONTINUED WEAK COOL
ADVECTION PRESSING SOUTH AND WEST. TROUGH DIGGING SOUTHWARD TO THE
EAST OF THE STATE WILL BACK FLOW ALOFT TO THE
NORTHWEST...PROVIDING VERTICAL SPEED AND DIRECTIONAL SHEAR TO
EASTERN NEW MEXICO COLUMN AND SUPPORTING STRONGER VERTICAL
DEVELOPMENT ON SUNDAY AFTERNOON. ELSEWHERE...CONTINUING NORTHBOUND
MOISTURE PENETRATION INTO THE STATE WILL PROLONG LOCAL FLASH
FLOODING WOE TO WRAP UP THE HOLIDAY WEEKEND ESSENTIALLY STATEWIDE.
INTO MONDAY...FLOW ALOFT VEERED TO NORTHWEST UP AND OVER
DEVELOPING RIDGE CORE OVER NORTHWEST MEXICO. BROAD SURFACE TROUGH
OVER THE STATE WILL SUPPORT LOCALIZED LOW LEVEL MOISTURE
CONVERGENCE OVER AND TO THE EAST OF THE CENTRAL MOUNTAIN CHAIN.
RIDGE ALOFT WILL RATCHET DOWN NORTHBOUND MOISTURE ADVECTION..AND
LEAVE DEVELOPING CONVECTION RECYCLED MOISTURE TO WORK WITH.
EXPECTING DOWNTICK IN INTENSITY AND COVERAGE...BUT SUFFICIENT
MOISTURE IN THE COLUMN TO SUPPORT SOME LOCAL FLASH FLOODING
CONCERN FOR SOUTHEASTERN HALF OF THE STATE. CONTINUED SLIGHT RISK
FOR SEVERE WEATHER OVER NORTHEAST END OF THE STATE.
INTO TUESDAY...TEMPERATURES FINALLY WARMING BACK UP TO NORMAL
LEVELS TUESDAY WITH SOME DRYING WORKING IN FROM THE NORTHWEST
AS RIDGE CORE EXPANDS EASTWARD ACROSS ARIZONA AND SOUTHWESTERN NEW
MEXICO. SURFACE TROUGH DEEPENING OVER EASTERN BORDER OF THE STATE
WILL PROVIDE LOW LEVEL MOISTURE CONVERGENCE TO SUPPORT CONVECTION
OVER THE EASTERN PLAINS...WITH INITIATION ON SLOPES NEAR THE
CONTINENTAL DIVIDE AND CENTRAL MOUNTAIN CHAIN IN GENTLE WEST FLOW.
LONGER TERM...WEDNESDAY THROUGH SATURDAY...RIDGE FIRMLY IN PLACE
OVER NEW MEXICO WEDNESDAY WILL BRING TEMPERATURES ABOVE NORMAL
STATEWIDE...WITH CONVECTION WORK CUT OUT TO PUSH THROUGH BROAD
SUBSIDENCE ALOFT. TEMPERATURE TRENDS WILL LEVEL OUT FROM THURSDAY
THROUGH THE WEEKEND...WITH GUIDANCE SUGGESTING SOME EASTWARD CREEP
OF THE RIDGE CORE...BUT NOT ENOUGH TO REOPEN THE NORTHBOUND
MOISTURE TAP AT LEAST FOR THE FIRST HALF OF THE WEEKEND.
