AFTER 84 DAYS, THE SNOW DROUGHT IS ABOUT TO END

DESPITE THE UNDER-ACHIEVING CLIPPER EVENT LAST NIGHT, WE STILL SEEM TO BE ON TARGET FOR THIS NEXT STORM. SOME ADJUSTMENTS HAVE BEEN MADE SINCE YESTERDAY ON THE SNOWFALL TOTAL AND PRECIP TYPES MAP. BASICALLY, THE LINES HAVE BEEN PULLED SOUTHWARD A BIT, GIVEN THE STRENGTH OF THE COLD PUSH TODAY AS WELL AS THE FLATNESS OF THE WAVE. OUR TIMING FROM YESTERDAY STILL LOOKS PRETTY GOOD. AS WE SAID YESTERDAY, THIS WILL BE A QUICK-HITTING SYSTEM, WITH THE BEST UPWARD MOTION AND PRECIP OCCURRING DURING ABOUT A 6 HOUR PERIOD. FROM START TO FINISH, THIS PRECIP EVENT WILL NOT LAST ANY LONGER THAN 12 HOURS. THE MAIN MECHANISM TO GENERATE OUR PRECIP WILL BE UPWARD MOTION FROM A JET STREAK GOING BY TO OUR NORTH...RIGHT REAR QUADRANT, AND ESPECIALLY WARM ADVECTION. THE SURFACE LOW WILL BE RELATIVELY WEAK, BUT IT WILL BE ABLE TO GENERATE SOME LOW LEVEL CONVERGENCE AS WELL.

HERE ARE SOME OF THE SPECIFICS WITH THIS STORM...

START TIME: 2-3 AM

ENDING TIME: 2-3 PM

PRECIP TYPE: ALL SNOW NORTH OF THE CITY, MOSTLY SNOW WITH PERHAPS A BIT OF SLEET TOWARD THE END IN THE CITY,

AND SNOW GOING OVER TO SLEET AND FREEZING RAIN FARTHER SOUTH

TIME OF BEST PRECIP: 4 OR 5 AM TO 10 OR 11 AM

ACCUMULATIONS: 3-6" CORE OF THE AREA, 1-3" SOUTH

FOLLOWING THE STORM, SKIES WILL AT LEAST PARTIALLY CLEAR TOMORROW NIGHT, AND IT WILL GET PRETTY COLD...ESPECIALLY IN THE NORTHERN SUBURBS WITH THE FRESH SNOW COVER. SUNDAY WILL START WITH SOME SUN, BUT THEN LOW CLOUDS WILL FORM OR MOVE IN LATER IN THE DAY AS THE FLOW TURNS AROUND FROM NORTHEAST TO EAST TO SOUTHEAST. DRIZZLE AND INLAND FREEZING DRIZZLE MAY BREAK OUT SUNDAY NIGHT, AND IT COULD BECOME VERY FOGGY IN SOME AREAS BY MONDAY MORNING AS HIGHER DEW POINT AIR MOVES OVER THE COLD GROUND. A SURGE OF MUCH MILDER AIR WILL COME NORTHWARD ON MONDAY AHEAD OF THE NEXT COLD FRONT. WE ARE IN LINE FOR PERIODS OF RAIN ON MONDAY, AND IT MAY EVEN T-STORM IN THE AFTERNOON, GIVEN THE STRENGTH OF THE SHORT WAVE APPROACHING FROM THE WEST. UNTIL WE GET INTO THE WARM SECTOR ON MONDAY, FOG WILL LIKELY BE A PROBLEM. BEHIND THAT FRONT,

TUESDAY LOOKS COOLER AND BRISK, BUT STILL ON THE MILD SIDE OF NORMAL FOR LATE JANUARY. THAT'S BECAUSE THAT AIR MASS WILL HAVE SOME PACIFIC AIR IN THE MIX.
