LOW PRESSURE LINGERING OVER THE NORTHEAST WILL CONTINUE TO PRODUCE
DAMP AND COOL CONDITIONS ACROSS THE REGION THROUGH THE END OF THE
WORK WEEK. THE LOW WILL SLOWLY DRIFT OFFSHORE FRIDAY, AND HIGH
PRESSURE WILL BUILD INTO THE REGION ON SATURDAY. HIGH TEMPERATURES

TEMPERATURES WILL RETURN TO NEAR SEASONABLE VALUES OVER THE
WEEKEND.
IN THE NORTHWEST, UNSETTLED WEATHER IS EXPECTED TO INCREASE ACROSS
THE REGION ON THURSDAY AS AN UPPER LEVEL SHORTWAVE TROUGH AND
SURFACE FRONTAL SYSTEM APPROACH FROM THE NORTHWEST. WIDESPREAD
SHOWERS AND THUNDERSTORMS AND HIGH ELEVATION MIXED PRECIPITATION
AND SNOW ARE FORECAST THROUGH THE END OF THE WEEK. RAINFALL AND
SNOWMELT ACROSS THE GREAT BASIN AND PACIFIC NORTHWEST MAY CAUSE
ISOLATED FLOODING ISSUES IN NEARBY STREAMS AND RIVERS. BELOW
NORMAL TEMPERATURES ARE FORECAST TO SPREAD ACROSS MUCH OF THE WEST
THROUGH THE END OF THE WEEK WITH HIGHS GENERALLY IN THE 50S AND
60S.
FURTHER INLAND, THE NORTHERN INTERMOUNTAIN WEST AND HIGH PLAINS
WILL EXPERIENCE ABOVE NORMAL TEMPERATURES THROUGH FRIDAY.
THURSDAY'S HIGHS WILL BE IN THE 70S AND LOWER 80S, AND FRIDAY'S
HIGHS WILL BE IN THE UPPER 60S AND LOWER 70S. SIGNIFICANT SNOWMELT
IS ANTICIPATED IN THESE REGIONS THIS WEEK, WHICH COULD LEAD TO
LOCALIZED FLOODING CONCERNS. ABOVE AVERAGE WARMTH IS EXPECTED TO
SPREAD SOUTH INTO THE REST OF THE CENTRAL U.S. FRIDAY INTO THE
WEEKEND.
IN THE SOUTHERN PLAINS, A STATIONARY FRONT WILL REMAIN DRAPED
ACROSS THE AREA THROUGH THURSDAY, THEN LIFT NORTHEAST AS A WARM
FRONT THURSDAY NIGHT THROUGH FRIDAY. WARM, MOIST CONDITIONS ARE IN
PLACE ACROSS THE AREA, WHICH WILL BE FAVORABLE FOR THUNDERSTORM
DEVELOPMENT EACH DAY. SCATTERED SEVERE STORMS WILL BE POSSIBLE ON
THURSDAY AFTERNOON AND EVENING IN PARTS OF TEXAS, OKLAHOMA, AND
SOUTHERN KANSAS WHERE THE STORM PREDICTION CENTER HAS ISSUED A
SLIGHT RISK OF SEVERE THUNDERSTORMS. SEVERE STORMS WILL BE CAPABLE
OF PRODUCING LARGE HAIL, DAMAGING WINDS, AND A COUPLE OF TORNADOES.
