THE COLDEST TEMPERATURE OF THIS COLD WAVE WAS ON JANUARY 2 WHEN THE TEMPERATURE HIT 19 BELOW ZERO, THE COLDEST TEMPERATURE IN CONCORD SINCE THE INFAMOUS COLD OF FEBRUARY 2015. AT LEAST THE TEMPERATURE DID WARM UP INTO THE 20S FOR A FEW DAYS, JUST LONG ENOUGH FOR AN INTENSE NOR`EASTER TO BRING 13 INCHES OF SNOW AND 47 MPH WINDS, CREATING BLIZZARD CONDITIONS ON JANUARY 4. MORE COLD AIR POURED IN RIGHT BEHIND THIS STORM. WHEN THE BRUTAL COLD FINALLY BEGAN TO EASE UP, CONCORD HAD SEEN SUBZERO TEMPERATURES FOR THE FIRST 7 DAYS OF JANUARY. GOING BACK TO LATE DECEMBER THIS STRETCH INCLUDED 12 STRAIGHT DAYS OF SUBZERO TEMPERATURES, THE 4TH LONGEST STRETCH ON RECORD. JUST WHEN THE INTENSE COLD SEEMED LIKE IT WOULD NEVER END, THE JANUARY THAW ARRIVED. CONCORD SAW THREE STRAIGHT DAYS IN THE 50S FROM JANUARY 11 THRU 13 ALONG WITH MORE THAN AN INCH OF RAIN. THIS WARM, WET WEATHER PUT A DENT IN THE DEEP EARLY SEASON SNOW PACK WHICH HAD DEVELOPED THROUGH THE COLD SPELL. A COLD FRONT ON JANUARY 13 BROUGHT AN END TO THE JANUARY THAW, WITH THE TEMPERATURE DROPPING FROM 57 DEGREES THAT MORNING ALL THE WAY DOWN TO 12 DEGREES BY MIDNIGHT. ALTHOUGH THE NEXT FEW DAYS SAW WELL BELOW NORMAL TEMPERATURES, IT WAS NOTHING COMPARED TO THE EXTREME COLD WHICH HAD OCCURRED JUST A FEW WEEKS EARLIER. IT ALSO DID NOT LAST NEARLY AS LONG. AFTER SOME MORE SNOW ON JANUARY 17, WARMER TEMPERATURES BEGAN TO MOVE BACK INTO THE REGION. AFTER A FEW DAYS OF TEMPERATURES IN THE 40S, THE NEXT WINTER STORM BROUGHT VERY LIGHT SNOW FOLLOWED BY FREEZING RAIN ON JANUARY 22 AND 23. WARMER WEATHER RETURNED AGAIN LATER IN THE MONTH WHEN CONCORD REACHED 49 DEGREES ON JANUARY 27 AND 28, BUT A COLD FRONT BROUGHT COOLER TEMPERATURES AGAIN FOR THE LAST FEW DAYS OF THE MONTH. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 22.0 DEGREES WHICH WAS 1.4 DEGREES ABOVE NORMAL. THE WARMEST JANUARY ON RECORD WAS IN 1932 WHEN IT WAS 31.8 DEGREES. THE COLDEST WAS ONLY 10.6 DEGREES IN 1977. THE INTENSE COLD SPELL THAT STARTED THE MONTH WAS ONE OF THE MOST LONG LASTING ON RECORD AT CONCORD. THERE WERE 12 STRAIGHT DAYS OF SUBZERO TEMPERATURES, TYING AS THE 4TH LONGEST SUCH STRETCH ON RECORD, AS THE FOLLOWING TABLE SHOWS. MOST CONSECUTIVE DAYS WITH TEMPERATURE ZERO OR LESS (SINCE 1868)...
