Winter Weather Week

Although amounts are still uncertain at this point, the Ozarks is still expected to receive a fairly good punch of winter weather next week.

Monday
The precipitation, for now, is expected to begin Monday afternoon; this probably won't be a big weather maker, but a little sleet and/or snow could fall on Monday afternoon. It might be hard for the atmosphere to saturate up everywhere by this time, so don't be surprised if little to nothing falls with this first wave. (Just my hunch.)

Monday night into Tuesday
Another wave of precip will also fall Monday night into Tuesday. That, to me, looks like it will be our big whammy.

From this morning's NWS Forecast Discussion:
"AT THIS POINT...THE MONDAY NIGHT AND TUESDAY MORNING PERIOD LOOKS LIKE OUR BEST SHOT AT ACCUMULATING WINTRY PRECIPITATION. WITH LOW LEVEL TRAJECTORIES STILL FROM THE EAST AND NORTHEAST...MOST AREAS SHOULD REMAIN AT OR BELOW FREEZING. WITH THAT WARM ADVECTION CONTINUING ABOVE THE COLD DOME...FREEZING RAIN AND SLEET WILL LIKELY BE THE MAIN PRECIPITATION TYPES.

Tuesday night and beyond
After things settle down on Tuesday, we will start to have more waves of energy pulsating toward the Ozarks over the next few days. It should all be said and done by Thursday morning.

From this morning's NWS Forecast Discussion:
THIS WILL BE THE PERIOD
WHERE UPPER LEVEL ENERGY WILL HAVE A BIGGER PLAY. WE WILL LIKELY SEE MULTIPLE BOUTS OF SHORT WAVE ENERGY RIDE THROUGH THE AREA UNTIL THE MAIN UPPER LEVEL TROUGH AXIS CLEARS BY LATER NEXT WORK WEEK. ANY ONE OF THESE WAVES WILL BE CAPABLE OF SPAWNING MORE
PRECIPITATION.
