.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT
THE EMERGENCE OF THE POSITIVE PNA PATTERN ACROSS THE CONUS WILL
KEEP MOST OF THE NORTHERN PLAINS DRY THROUGH THE NEXT WEEK OR SO.
TEMPERATURES WILL REMAIN THE MAIN CHALLENGE. WITH LESS CLOUDINESS
ON MONDAY AND TUESDAY THE TEMPERATURES SHOULD RECOVER A LITTLE.
OVERNIGHT LOWS WILL BE COOL...ESPECIALLY IN THE LOW LYING JAMES
RIVER AND BIG SIOUX RIVER VALLEYS...WHERE COLD AIR DRAINAGE WILL
LIKELY OCCUR. OTHERWISE A SLOW WARM UP IS EXPECTED THROUGH MID
WEEK.


.LONG TERM...WEDNESDAY THROUGH SUNDAY
NO REAL CHANGES TO THE LONG TERM FORECAST. THE UPPER LEVEL PATTERN
WILL FEATURE A RIDGE OVER THE WEST COAST WHILE A LOW PRESSURE
SYSTEM SPINS OVER THE GREAT LAKES REGION. THIS LEAVES THE NORTHERN
PLAINS IN NORTHWEST FLOW ALOFT...WITH NO REAL NOTABLE WAVES OF
ENERGY IDENTIFIED AT THIS POINT. THEREFORE...MAINTAINED THE DRY
FORECAST. TEMPERATURES WILL SHOW A VERY SLOW WARMING TREND. 850 MB
TEMPS RANGING FROM THE LOW TO MID TEENS CELSIUS AT THE BEGINNING OF THE
FORECAST PERIOD WILL RISE TO THE UPPER TEENS TO LOW 20S CELSIUS BY
THE END OF THE PERIOD.
