FORECAST FOR OVERNIGHT INTO MIDDAY THURSDAY. A LIGHT SNOW EVENT POSSIBLE LATE TONIGHT INTO MIDDAY THURSDAY AN UPPER LEVEL DISTURBANCE WILL RACE ACROSS THE MID MISSISSIPPI VALLEY LATE TONIGHT INTO THURSDAY MORNING. WITH ITS PASSAGE THIS FEATURE IS EXPECTED TO PRODUCE A NARROW BAND OF LIGHT SNOW. SNOW ACCUMULATIONS OF LESS THAN AN INCH ARE EXPECTED TO OCCUR GENERALLY 25 MILES EITHER SIDE OF A LINE FROM FREDERICKTOWN MISSOURI TO OWENSBORO KENTUCKY. HOWEVER ACCUMULATIONS OF ONE TO TWO INCHES ARE POSSIBLE OVER THE MISSOURI COUNTIES OF PERRY, CAPE GIRARDEAU AND BOLLINGER AND THE ILLINOIS COUNTIES OF JACKSON AND UNION. THE TRACK OF THIS SYSTEM IS STILL A BIT UNCERTAIN AND THE LIQUID EQUIVALENT PRECIPITATION VARIES CONSIDERABLY BETWEEN COMPUTER MODELS. SO ADJUSTMENTS MAY BE NEEDED AS NEW DATA BECOMES AVAILABLE AS ALWAYS THESE SMALL CHANCES OF SNOW NEED TO BE WATCHED AS CONDITIONS CAN CHANGE RAPIDLY. AS ALL OF YOU KNOW IT SEEMS LIKE WHEN WE HAVE LIGHTER CHANCES OF SNOW THAT WE ALWAYS WIND UP WITH MORE THAN IS FORECAST. THIS IS MAINLY BECAUSE THE SMALLER LESS ORGANIZED WEATHER SYSTEMS ARE HARDER TO FORECAST AND TEND TO DEVELOP AS TIME PASSES. ALTHOUGH I WOULDNT EXPECT ANY HUGE SNOWFALL TOTALS BUT I WOULDNT BE SURPRISED TO SEE MORE THAT WHAT IS FORECAST. I WOULD PREPARE FOR A NOTHING EVENT TO AN INCH OR SO OF SNOWFALL FOR OUR REGION. DONT LET THE KIDS GET THEIR HOPES UP TO HIGH BECAUSE THIS IS A VERY SMALL SYSTEM BUT IT IS ONE WORTH WATCHING AS IT CROSSES THE MISSISSIPPI RIVER EARLY TOMORROW MORNING.
