DRAWS CLOSER. MOST NCEP MODELS SEEM TO KEEP ANY PRECIP HOLDING OFF
TILL THE 3 TO 6Z TIME FRAME. CONCERNED THAT WITH SUCH STRONG LIFT
AND DYNAMICS COMING INTO PLAY BY EVENING THAT PRECIP COULD BREAK OUT
AHEAD OF THIS MAIN AREA. 4KM SPC WRF SUGGESTS THIS WITH DEVELOPMENT

AMOUNTS TO LINE UP WITH MODELS TRENDS. THE WARM NOSE THAT HAS BEEN
ADVERTISED THE PAST SEVERAL RUNS MAY BE DEPARTING BY THE TIME THE
STEADIER PRECIP ARRIVES. HOWEVER...THERE ARE MANY INSTANCES THAT THE
MODELS ARE UNDERDONE ON THE AMOUNT OF WARM AIR ALOFT AND ITS
EFFECTS. TOP DOWN PROCEDURES SUGGEST LIMITED ICING POTENTIAL WITH
MORE SLEET IN SE AREAS. NOT READY TO FULLY DROP ICE MENTION SO HAVE
LOWERED ICE ACCUMS IN THE SE AND NUDGED UP SNOW FALL. SNOW WILL BE
FALLING EVERYWHERE AFTER MIDNIGHT WHEN THE HEAVIEST ACCUMS ARE
EXPECTED. HRRR MODEL SHOWS HEAVIER SNOW COULD EXTEND EVEN INTO
