AMOUNTS OVER THE NORTHEAST COULD BE LOCALLY HEAVY...WITH SOME
LARGER HAIL POSSIBLE NEAR THE TEXAS BORDER.

MODELS...IN REASONABLE AGREEMENT ON BASIC PATTERN THROUGH THE
UPCOMING WORK WEEK AND INTO THE WEEKEND IN WEAKLY FORCED PATTERN.
RIDGE CORE WILL DRIFT EAST TO THE RED RIVER VALLEY OF NORTHERN
LOUISIANA...AS CLOSED LOW DEEPENS OVER NORTHERN CALIFORNIA.
RESULTING SOUTHWEST FLOW WILL START TO WORK ANOTHER PLUME OF
MOISTURE INTO WESTERN NEW MEXICO THROUGH FRIDAY HEADING INTO THE
WEEKEND. RIDGE CORE WILL SHIFT TO CENTRAL TEXAS ON SATURDAY AND
EXPAND WESTWARD ACROSS SOUTHERN NEW MEXICO BY MONDAY. CORE WILL
SHIFT TO WESTERN NEW MEXICO AND EASTERN ARIZONA TUESDAY
NIGHT...WITH CORE STRENGTHENING IN PLACE ON WEDNESDAY AND
REMAINING THERE THROUGH THE REMAINDER OF THE WORK WEEK INTO THE
FOLLOWING WEEKEND.

OVERNIGHT...A REPEAT OF LAST NIGHTS TEMPERATURES AS THE LAST OF
THE NORTHEAST PLAINS THUNDERSTORMS DRIFT OFF INTO THE TEXAS AND
OKLAHOMA PANHANDLES. RAIN COULD BE HEAVY AT TIMES NEAR THE TEXAS
LINE THROUGH LATE EVENING. NORTHEAST WINDS COMBINED WITH EASTERN
PLAINS CONVECTION WILL PUSH SOME COOLER AIR AGAINST THE CENTRAL
MOUNTAIN CHAIN WITH SOME MODEST GAP FLOW DEVELOPING OVERNIGHT OVER
THE RIO GRANDE VALLEY.

FOR FRIDAY...RIDGE CORE SHIFTING TO CENTRAL TEXAS WITH SOUTHWEST
FLOW STARTING TO ENCROACH ON WESTERN NEW MEXICO...AS SURFACE LOW
REMAINS NEAR THE TEXAS BIG BEND COUNTRY. EASTERLY COMPONENT TO
WINDS OVER THE EASTERN HALF OF THE STATE WILL PROVIDE SOME UP
SLOPE ENHANCEMENT TO SHOWERS OVER THE CENTRAL MOUNTAIN CHAIN AND
SANGRE DE CRISTO RANGE...AND AGAINST THE WESTERN MOUNTAINS AND
CONTINENTAL DIVIDE. BEST CHANCES FOR HEAVIER RAIN WILL REMAIN OVER
THE NORTHEAST HIGHLANDS AND ADJACENT PLAINS WITH THUNDERSTORMS

DIRECTIONS PICKING UP MORE SOUTHERLY COMPONENT HEADING WESTWARD.
STEADY TEMPERATURE TRENDS.

FOR SUNDAY...ACTIVE CONVECTION AND GOOD CHANCES FOR HEAVIER RAINS AS
RIDGE CORE REMAINS OVER EAST TEXAS...AND MOISTURE PLUMES PUSH
NORTHWARD ACROSS WESTERN AND CENTRAL NEW MEXICO. HEAVIEST RAINFALL
EXPECTED OVER THE WESTERN AND NORTHERN MOUNTAINS...AND ALONG THE
CENTRAL MOUNTAIN CHAIN. SURFACE WINDS VEERING TO SOUTH AND
SOUTHWEST AS SURFACE LOW SETS UP OVER CENTRAL ARIZONA UNDER
DOWNSTREAM LIMB OF PERSISTENT WEST COAST TROUGH. HEIGHT FALLS
UNDER THE NEARBY TROUGH WILL HELP EASE MAXIMUM TEMPERATURES A FEW
DEGREES LOWER...WITH MOST SPOTS RUNNING NORMAL OR A FEW DEGREES
BELOW FOR MUCH OF THE STATE.

OUTLOOK...MONDAY THROUGH WEDNESDAY...RIDGE CORE RETURNING TO
CENTRAL TEXAS MONDAY...AND DRIFTING TO THE SOUTHWEST BOOT HEEL AND
SOUTHEAST ARIZONA BY MIDWEEK. ACTION WILL ALLOW SOME NORTHWEST
FLOW ALOFT TO CLIP THE NORTHEAST PLAINS...AND PLACE THE REST OF
THE STATE IN RECYCLE MODE WITH WIDESPREAD SHOWER COVERAGE EACH
DAY. THUNDERSTORM FOCUS WILL BE NORTH AND WEST MONDAY AND TUESDAY
WITH COVERAGE ALONG THE CENTRAL MOUNTAIN CHAIN...WITH COVERAGE
INCLUDING THE EAST BY WEDNESDAY. SOUTHWEST WINDS GRADUALLY BACKING
