WELL SOME MODELS ARE IN AGREEMENT ON SOME SNOWFALL ACROSS NORTH ALABAMA ON SATURDAY. THE NAM IS OUR FRIEND RIGHT NOW AS IT HAS THE MOST MOISTURE FOR US AT THIS TIME. THE EUROPEAN WHICH HAS BEEN THE BRUTE WITH THE MOST MOISTURE WITH IT OVER THE LAST FEW DAYS IS NOW THE DRIEST OF THE ONES LISTED BELOW. THE CANADIAN ALSO IS DRIER THAN RECENT RUNS. WE ARE CONFIDENT IN SAYING THAT SNOW WILL FALL ACROSS NORTH ALABAMA. NOW IT WILL NOT BE A WHITE CHRISTMAS IN THE STORYBOOK SENSE AS WE WILL NOT WAKE UP TO A BLANKET OF SNOW ON THE GROUND. THIS SYSTEM WILL START OUT AS RAIN AND CHANGE OVER TO A WINTRY MIX AROUND THE NOON HOUR IN THE HUNTSVILLE METRO AND BE ALL SNOW BY 4-5PM. AT THE BOTTOM IS MY ACCUMULATION FORECAST BASED ON MODEL DATA AND OTHER FORECASTS. I WILL TWEEK IT TOMORROW AFTERNOON AS I AM SURE THE TRACK OF THE LOW WILL CHANGE A LITTLE. ALL IT WILL TAKE IS A LITTLE JOG TO THE NORTH OR SOUTH AND OUR CHANCE WILL CHANGE CONSIDERABLY. AT THIS MOMENT THE NWS IN HUNTSVILLE DOES NOT HAVE ANY WINTER WX ADVISORIES OUT FOR THE COUNTIES IN THEIR SERVICE AREA. OHX (NASHVILLE NWS) DOES HAVE WINTER STORM WATCHES OUT FOR MOST OF THEIR COVERAGE AREA. WE VERY WELL COULD SEE AT THE LEAST A WINTER WX ADVISORY ISSUED LATER ON CHRISTMAS EVE OR DURING THE DAY ON CHRISTMAS. AS THE ACCUMULATIONS OCCUR LATE SATURDAY AND THE TEMPERATURES FALL THIS WILL CREATE SLICK SPOTS ON
AREA ROADWAYS ESPECIALLY BRIDGES AND OVERPASSES DUE TO TEMPERATURES
BELOW FREEZING.
BEGIN TAKING THE NECESSARY PRECAUTIONS NOW AND STAY TUNED TO FUTURE
WEATHER FORECASTS AND STATEMENTS FROM THE NATIONAL WEATHER SERVICE IN
HUNTSVILLE, LOCAL NEWS, AND HERE. NEXT POST WILL BE TOMORROW AFTERNOON.
RPM VALID 7PM SATURDAY
