  Winds:   With below zero wind chill? Probably blowing and drifting snow as well. Should be fun. This post has been edited by _AR_: Dec 21 2008, 02:27 PM --------------------    |

Mt Holly is waiting to decide to issue wind and wind chill advisories this evening. They say that the winds are predicted to be just below advisory level, and the wind chill is predicted to be just above advisory level. So, if it is just slightly windier or colder than predicted, we will be in advisory criteria.
From this morning's AFD: QUOTE .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
IT WILL BECOME VERY WINDY AND VERY COLD AS THE STRONG LOW MOVES UP ALONG COASTAL NEW ENGLAND AND INTO EASTERN CANADA. AT THIS POINT, WE ARE COMING UP WITH VALUES JUST BELOW WIND ADVISORY CRITERIA FOR TONIGHT AND MONDAY. WE ARE ALSO COMING UP WITH WIND CHILL VALUES THAT ARE JUST ABOVE CRITERIA. AS A RESULT, WE WILL WAIT UNTIL THE PRECIPITATION EVENT IS OVER TO TAKE ANOTHER LOOK AT THE POSSIBILITY OF WIND AND/OR WIND CHILL ADVISORIES FOR OUR REGION.

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED A WIND CHILL ADVISORY...WHICH IS IN EFFECT FROM 4 AM TO 10 AM EST MONDAY. THE COLDEST AIR MASS OF THE SEASON SO FAR WILL INVADE THE AREA TONIGHT. THE COMBINATION OF LOW TEMPERATURES IN THE SINGLE NUMBERS COUPLED WITH GUSTY WEST WINDS WILL PRODUCE WIND CHILL FACTORS OF AROUND 15 DEGREES BELOW ZERO COME MONDAY MORNING. ONLY MODEST RELIEF IS EXPECTED MONDAY AFTERNOON. A WIND CHILL ADVISORY MEANS THAT VERY COLD AIR AND STRONG WINDS WILL COMBINE TO GENERATE LOW WIND CHILLS. THIS WILL RESULT IN FROST BITE AND LEAD TO HYPOTHERMIA IF PRECAUTIONS ARE NOT TAKEN.

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED A WIND ADVISORY...WHICH IS IN EFFECT UNTIL 1 PM EST MONDAY. THE DOUBLE BARREL LOW PRESSURE SYSTEMS AROUND THE AREA WILL MERGE INTO ONE NEAR EASTERN MAINE OVERNIGHT AND CONTINUE TO INTENSIFY ON ITS WAY THROUGH THE CANADIAN MARITIMES ON MONDAY. WEST WINDS WILL CONTINUE TO INCREASE TONIGHT AND PROBABLY REACH THEIR PEAK DURING THE FIRST HALF OF THE DAY ON MONDAY. SUSTAINED WEST WINDS WILL INCREASE TO 20 TO 30 MPH WITH PEAK GUSTS REACHING AROUND 45 MPH. THESE WIND SPEEDS SHOULD KNOCK DOWN SOME WEAK TREES, TREE LIMBS AND WIRES. THE TREES ARE GOING TO BE UNDER PRESSURE FROM SEPARATE FORCES. FROM THE INTERSTATE 95 CORRIDOR AND NORTHWESTWARD THERE IS STILL ICE ON SOME TREES. THIS WILL MAKE IT EASIER FOR THEM TO BE SNAPPED. FARTHER TO THE SOUTHEAST, PRECIPITATION TOTALS SO FAR THIS MONTH HAVE AVERAGED TWICE THE NORMAL DECEMBER AMOUNT ALREADY. THE SUPERSATURATED SOIL WILL MAKE IT EASIER FOR SHALLOW ROOTED TREES TO BE KNOCKED DOWN. IN ADDITION TO THE WIND, THIS AIR MASS WILL BE THE COLDEST ONE OF THE SEASON SO FAR. WIND CHILL FACTORS COME MONDAY MORNING WILL AVERAGE AROUND ZERO WITH READINGS WELL BELOW ZERO OVER THE HIGHER TERRAIN. PLEASE DRESS APPROPRIATELY IF YOU HAVE TO SPEND MUCH TIME OUTDOORS. BE PREPARED FOR THE LIKELIHOOD OF SCATTERED POWER OUTAGES. ALSO IF POSSIBLE DO NOT PARK VEHICLES UNDER TREES THAT ARE ENCASED IN ICE OR ARE SHALLOW ROOTED SUCH AS WILLOWS. A WIND ADVISORY MEANS THAT WIND GUSTS OF AROUND 45 MPH ARE EXPECTED. WINDS THIS STRONG CAN MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH PROFILE VEHICLES ESPECIALLY ON NORTH TO SOUTH OVERPASSES. USE EXTRA CAUTION. WINDS WILL DIMINISH MONDAY AFTERNOON AS THE INTENSE LOW PRESSURE SYSTEM SLOWLY MOVES FARTHER AWAY. $$ STAUBER/GIGI I maxed out at 32F today with the "warm surge". Dropping now. The sun was shining all day and barely melt the snow. The snow pack will aid radiational cooling tonight with the clear skies. Winds have already started to pick up.
