...AREAS OF HEAVY RAIN AND FLASH FLOODING POSSIBLE ACROSS THE
SOUTHERN HIGH PLAINS OVER THE NEXT FEW DAYS...
...ABOVE AVERAGE TEMPERATURES REMAIN THROUGHOUT THE NORTHERN
PLAINS AND BUILD INTO THE PACIFIC NORTHWEST BY TUESDAY...
A CONTINUING STAGNANT UPPER-LEVEL PATTERN IS FORECAST TO REMAIN
OVER NORTH AMERICA THE NEXT COUPLE OF DAYS, WITH UPPER-LEVEL LOWS
DEEPENING BY TUESDAY NEAR THE NORTHEAST AND SOUTHWEST, PROVIDING A
FOCUS FOR AREAS OF UNSETTLED WEATHER. INSTANCES OF FLASH FLOODING
REMAIN A NOTABLE WEATHER HAZARD THROUGHOUT THE SOUTHERN HIGH
PLAINS EACH DAY INTO THE BEGINNING OF THIS WEEK. RECENT RAINFALL
HAS OVERLY SATURATED GROUND CONDITIONS AND LEFT MUCH OF NORTHEAST
NEW MEXICO AND THE TEXAS PANHANDLE HIGHLY SUSCEPTIBLE TO RENEWED
FLASH FLOODING. ADDITIONALLY, BURN SCARS THROUGHOUT THE HIGHER
TERRAIN OF NEW MEXICO ARE ALSO SENSITIVE TO INTENSE RAINFALL RATES
LEADING TO RAPID RUNOFF. TO FURTHER HIGHLIGHT THE FLOODING
CONCERNS, A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL REMAINS
IN EFFECT THROUGH EARLY MONDAY MORNING FROM WESTERN OKLAHOMA TO
NORTHEAST NEW MEXICO, INCLUDING THE TEXAS PANHANDLE. A SLIGHT RISK
OF EXCESSIVE RAINFALL CONTINUES ACROSS NORTHEAST NEW MEXICO ON
MONDAY AND TUESDAY. ELSEWHERE, SCATTERED SHOWERS AND THUNDERSTORMS
ARE ALSO EXPECTED THROUGHOUT THE REMAINING OF THE HIGH PLAINS,
SOUTHERN PLAINS, ROCKIES, AND NORTHERN GREAT BASIN. SOME STORMS IN
THESE REGIONS MAY ALSO PRODUCE INTENSE DOWNPOURS AND LEAD TO
LOCALIZED FLASH FLOODING.
A STRENGTHENING LOW PRESSURE SYSTEM OFF THE COAST OF NEW ENGLAND
WILL PROVIDE COOL TEMPERATURES AND NUMEROUS SHOWERS THE NEXT FEW
DAYS AS IT VERY SLOWLY PUSHES NORTHWARD INTO NOVA SCOTIA. TO ITS
WEST, A SINKING COLD FRONT ENTERING THE GREAT LAKES AND NORTHERN
PLAINS MAY SPARK SCATTERED SHOWERS AND STORMS THROUGHOUT THE
REGION, WHILE ALSO OFFERING RELIEF FROM THE WELL ABOVE AVERAGE
TEMPERATURES. COOLER AIR IS FORECAST TO REMAIN ALONG THE EAST
COAST AND NORTHEAST WHILE IMPACTED BY CONSISTENT NORTHERLY FLOW,
WHICH MAY ALLOW FOR SKIES TO BECOME OPAQUE AS FAR WEST AS THE OHIO
VALLEY DUE TO EXPANSIVE WILDFIRES IN QUEBEC, CANADA.
OUTSIDE OF TYPICAL SUMMERTIME IMPULSE THUNDERSTORMS THROUGHOUT THE
DEEP SOUTH AND CENTRAL U.S., THE OTHER WEATHER STORY OF NOTE
INVOLVES WELL ABOVE AVERAGE TEMPERATURES BUILDING INTO THE PACIFIC
NORTHWEST BY TUESDAY AS UPPER-LEVEL RIDGING SQUEEZES WESTWARD TO
THE NORTH OF A CLOSED UPPER-LEVEL LOW OVER THE SOUTHWEST. HIGHS
INTO THE UPPER 80S AND LOW 90S ARE EXPECTED FOR THIS REGION.
