TONIGHT...
THE NORTHERN PLAINS COLD FRONT/SURFACE TROUGH WILL MOVE INTO THE

IN MANY PLACES, WHILE THE PACIFIC NORTHWEST WILL EXPERIENCE THE
MOST ANOMALOUS WARMTH WITH HIGHS IN THE 80S AND 90S. WARM LOWS IN
THE 50S AND 60S MAY END UP BREAKING RECORDS THROUGH THE WEEKEND.
THE STRONG COLD FRONT SWEEPING DOWN THE EAST COAST WILL INTRODUCE
COOLER AIR TO THE REGION OVER THE NEXT COUPLE OF DAYS. LOW
TEMPERATURES DESCENDING TO AND BELOW FREEZING IN THE NORTHEAST
COULD SET NEW RECORDS BY THURSDAY MORNING, APPROACHING RECORD COLD
FOR SO LATE IN THE SPRING. CROPS AND LIVESTOCK THAT ARE SENSITIVE
