A ANOTHER SYSTEM WILL TAKE SHAPE OVER THE CENTRAL PLAINS ON SATURDAY
THEN WORK TO THE EAST-NORTHEAST THROUGH NORTHERN IN TOWARDS LAKE
ERIE BY SUNDAY EVENING. WARMER AIR WILL ADVECT IN FROM THE SOUTH
AHEAD OF THE APPROACHING SYSTEM PUSHING OUR TEMPERATURES INTO THE
LOW/MID 40 SATURDAY AFTERNOON AND INCREASING CLOUDS DUE TO
ISENTROPIC LIFTING. PRECIPITATION WILL SPREAD FROM THE WEST-
NORTHWEST TO THE EAST DURING THE DAY SATURDAY. INITIALLY,
PRECIPITATION COULD FALL AS A WINTRY MIX OF RAIN/SNOW DUE TO
LINGERING COLD AIR AT THE SURFACE EARLY ON SATURDAY. STILL SOME
DISCREPANCY IN THE FORECAST MODELS WHEN IT COMES TO ANY ACCUMULATING
SNOW. CURRENT THINKING IS WITH A WARM GROUND AND TEMPERATURES
WARMING TO ABOVE FREEZING AS THE PRECIPITATION ARRIVES, MOST WILL
SEE RAIN WITH ANY SLUSHY ACCUMULATIONS OF A COATING TO NEAR AN INCH
WILL BE OVER SOUTHERN IN, WITH HIGHER AMOUNTS AS YOU WORK NORTHWARD
INTO CENTRAL IN. ALL OF THE PRECIPITATION SHOULD TRANSITION OVER TO
ALL RAIN BY LATE IN THE DAY INTO SATURDAY NIGHT AND INTO SUNDAY.
MOST OF THE PRECIPITATION SHOULD BE OUT OF THE CWA BY SUNDAY
EVENING.
SURFACE HIGH WILL BUILD IN BEHIND THE DEPARTING SYSTEM AND A COLD
FRONT SUNDAY NIGHT INTO MONDAY. ANOTHER ROUND OF COLDER AIR WILL
WORK INTO THE AREA WITH LOWS IN THE MID 20S MONDAY MORNING AND HIGHS
IN THE MID/UPPER 30S ON MONDAY WITH MAINLY DRY CONDITIONS DURING THE
DAY.
THE NEXT IMPACTFUL SYSTEM LOOKS TO ARRIVE MONDAY NIGHT INTO TUESDAY
WITH BETTER CHANCES OF MOST OF THE AREA SEEING SOME SNOW. THE
CHALLENGE IN THE DETERMINISTIC MODELS IS HOW MUCH MOISTURE WILL BE
AVAILABLE AND HOW STRONG WILL THIS SYSTEM BE AS IT DEVELOPS OVER THE
WESTERN GULF MONDAY AND THEN AND THEN SLIDES OVER THE SOUTHEAST US
MONDAY NIGHT INTO TUESDAY. RIGHT NOW THE GFS IS THE MOST BULLISH
WITH ITS 00Z RUN BRING THE MOST MOISTURE AND POTENTIALLY HIGHER SNOW
AMOUNTS WHILE THE EURO IS KEEPING MOST OF THE MOISTURE ON THE
SOUTHERN AND EASTERN SIDE OF THE SYSTEM.
WEATHER TURNS DRIER BUT REMAINS CHILLY FROM WEDNESDAY INTO THURSDAY
WITH HIGHS IN THE LOW/MID 40S.
