..UNUSUAL WARMTH FOR MARCH
AFTER A COOL START, MOTHER NATURE DECIDED TO GIVE THE REGION SOME
SPRING-TIME TEMPERATURES. IN GENERAL, HIGH TEMPERATURES FOR THE
INTERIOR LOWLANDS ARE IN THE MIDDLE TO UPPER 50S FOR MID-MARCH, AND
50 TO 55 DEG ALONG THE COAST. SO, TEMPERATURES OVER THE PAST FEW
DAYS HAVE BEEN QUITE ABOVE AVERAGE. ON AVERAGE, MOST SITES ONLY SEE
ONE DAY ABOVE 70 DEG IN MARCH. COASTAL AREAS HAVE ALREADY COOLED
BACK TO AVERAGE, AND THE INTERIOR WILL MORE TYPICAL MID-MARCH
TEMPERATURES ON WEDNESDAY.
SO, HOW UNUSUAL IS THIS WARMTH? RARE. BUT, NOT OUT OF THE QUESTION
OF POSSIBILITY. MANY STATIONS HAVE SEEN TEMPERATURES ABOVE 70 DEG
EARLIER THAN MID-MARCH. BUT, WHAT MAKES THIS STRETCH OF WARM DAYS
STAND OUT IS NUMBER OF DAYS AND THE CONSECUTIVE DAYS OF SUCH WARMTH.
FOR MANY OF THE INTERIOR LOCATIONS, ONE HAS TO GO BACK TO MAR 2019
OR MAR 2005 TO SEE AS MANY DAYS IN MARCH WITH 70 DEG. BUT, EVEN
FARTHER BACK TO MARCH 1994 FOR AS MANY CONSECUTIVE DAYS OF 70+ DEG.
