915 PM CST THU NOV 27 2014 //ORD AND MDW CONCERNS...UPDATED 03Z..

* POTENTIAL FOR A PERIOD OF LIGHT SNOW EARLY FRIDAY MORNING

* GUSTY SOUTHERLY WINDS MID FRIDAY MORNING THROUGH THE AFTERNOON

KREIN //DISCUSSION...UPDATED 00Z..

LATEST SATELLITE AND RADAR TRENDS INDICATING THAT CLOUD COVER AND SNOW SHOWERS ARE BECOMING MORE RAGGED AND DECREASING IN COVERAGE WITH SUNSET AND AS HIGH PRESSURE BUILDS ACROSS THE REGION. ANY LINGERING SNOW SHOWERS SHOULD COME TO AN END BY ARND 01Z...EXCEPT FOR GYY...WHICH IS STILL UNDER A LAKE FETCH WITH NWLY WINDS. AS WINDS BECOME MORE WLY LATER THIS EVENING...ANY LAKE INFLUENCE WILL SHUT OFF AND CONDITIONS AT GYY SHOULD BECOME QUIET AS WELL

THE NEXT CONCERN IS FOR THE POTENTIAL FOR ANOTHER BRIEF PERIOD OF SNOW TOMORROW MORNING. THE LATEST MODEL GUIDANCE STILL INDICATES A MID LEVEL IMPULSE DROPPING OUT OF THE NRN PLAINS WHILE A WEAK WARM FRONT SETS UP ACROSS THE UPPER MISSOURI VALLEY TO NEAR THE IL/WI BORDER. THERE WILL BE A SHORT WINDOW OF OPPORTUNITY FOR SOME LIGHT SNOW IF THERE IS A DEEP ENOUGH LAYER OF MOISTURE IN PLACE AT THE TIME OF OPTIMAL UPPER LEVEL FORCING. THE LATEST HIGH RESOLUTION MODEL GUIDANCE SUGGESTS THAT THERE COULD BE A PERIOD OF LIGHT SNOW DURG THE MORNING HOURS FOR PERHAPS 2 HOURS...BUT TIMING THE SNOW IS STILL UNCERTAIN. SO...WILL MAINTAIN THE GOING FORECAST OF A 3 HOUR TEMPO GROUP...THOUGH THIS IS LIKELY TOO LONG MORE PRECISE TIMING SHOULD BE DETERMINED IN LATER UPDATES. REGARDLESS OF EXACT TIMING...ONLY LIGHT ACCUMULATIONS...PERHAPS A HALF INCH OR LESS IS EXPECTED

FOR THE REMAINDER OF THE DAY TOMORROW...FORECAST CONCERNS SHIFT TO GUSTY SOUTHERLY WINDS DEVELOPING IN THE MID/LATE MORNING AS HIGH PRESSURE SETTLES OVER THE SERN CONUS AND LOW PRESSURE DEVELOPS OVER THE NRN PLAINS. OCCASIONAL GUSTS TO ARND 20KT ARE LIKELY...AND POTENTIALLY HIGHER ARE POSSIBLE WITH DEEPER MIXING IF ENOUGH SUNSHINE CAN BREAK THROUGH THE CLOUD COVER
