************WEATHER UPDATE************** Get reay for some extremely cold nights to come our way over Monday night and Tuesday night. Early Tuesday morning and Wednesday morning temps will be well below zero. Then after that we will see a warming tend of temps into the 30s by next Saturday. Read following thread for more info. PRECIPITATION SO I HAVE HIGH CONFIDENCE THERE WILL BE LIGHT SNOW ALONG THE I-94 CORRIDOR SUNDAY NIGHT. ONCE THAT IS DONE A JET CORE ON THE NORTHERN STREAM...DIVING DUE SOUTHEAST FROM THE NORTHERN ARCTIC TOWARD HUDSON BY TUESDAY BRINGS US OUR LAST SURGE OF VERY COLD AIR FOR TUESDAY. SINCE THE JET CORE THIS TIME WILL BE WELL NORTH OF MICHIGAN THIS WILL BE SHALLOW COLD AIR AND WINDS AT THE SURFACE WILL BE NORTHEAST SO WE GET TO SEE MOSTLY SUNNY SKIES FOR A CHANGE! EVEN SO WITH SNOW ON THE GROUND OVER MOST OF THE AREA IT WILL BE VERY COLD ONE LAST DAY. LONG TERM (TUESDAY THROUGH SATURDAY) ISSUED AT 320 PM EST SAT JAN 10 2015 THE LONG TERM PORTION OF THE FCST LOOKS TO BE VERY QUIET FOR THIS TIME OF THE YEAR. WE WILL START OFF WITH A COLD MORNING AT THE BEGINNING OF THE PERIOD...AND THEN MODERATE AT THE END OF THE PERIOD. WE WILL SEE A VERY COLD MORNING TUE MORNING AND AGAIN ON TUE NIGHT/WED MORNING. HIGH PRESSURE PROVIDING A LIGHT GRADIENT AND MAINLY CLEAR SKIES...WILL COMBINE WITH OUR SNOW PACK TO ALLOW MOST TEMPS TO DROP BELOW ZERO TUE MORNING AND WED MORNING. SOME MODERATION IN TEMPS WILL TAKE PLACE FOR WED AND THU AS RETURN FLOW FROM THE WSW WILL SET UP OVER THE AREA. HIGH PRESSURE WILL DROP SOUTH...AND WE WILL EVENTUALLY SEE A COLD FRONT TRY TO APPROACH THE AREA FROM THE NW. TOUGH TO TELL HOW FAR SOUTH THIS FRONT WILL MAKE IT...BUT IT COULD BRING A LOW CHC OF SNOW TO THE NRN PORTION OF THE AREA ON THU. THE FRONTAL POSITION WILL ALSO DICTATE HOW WARM WE GET. THE GFS TAKES IT A BIT FURTHER SOUTH WHILE THE EURO HOLDS IT UP NORTH OF THE AREA. THE BEST MODERATION IN TEMPS WILL COME AT THE END OF THE PERIOD. AFTER THE THU SYSTEM MOVES BY...WE WILL GET BACK INTO A RETURN FLOW PATTERN ONCE AGAIN. A ZONAL FLOW ALOFT WILL KEEP THE COLD AIR AND WAVES OF LOW PRESSURE FAR ENOUGH NORTH TO KEEP OUR AREA DRY. WE SHOULD SEE TEMPS AT LEAST GET INTO THE 30S BY NEXT SAT.
