Slug Of Moisture By Wed Night / Thurs. Morning

THE CONCERN IS STILL THERE FOR A SLUG OF MOISTURE TO RAPIDLY MOVE ACROSS THE STATE WEDNESDAY NIGHT INTO THURSDAY MORNING. MORE ON THAT IN A SECOND.

TODAY SOUTHWEST WINDS AHEAD OF THE SECOND SHOT OF COLD AIR WARMS US INTO THE MID AND UPPER 40'S. ANOTHER VERY, VERY COLD AND WINDY DAY CAN BE EXPECTED TUESDAY AS A NEW ARCTIC HIGH SETTLES INTO THE AREA.

NOW ON THE MAP ABOVE YOU CAN SEE THAT NEW ARCTIC HIGH OFF THE CAROLINA COASTLINE AND A WAVE OF LOW PRESSURE OVER THE TEXAS PANHANDLE. THIS IS A COMPUTER GENERATED MODEL FROM THE UKMET. WITH THE CIRCULATION AROUND THE TWO PRESSURE AREAS, THAT WOULD TRANSPORT A SOUTHERLY FETCH OF AIR INTO ARKANSAS. THAT MAY BE THE KEY TO THIS WHOLE THING. TEMPERATURES SHOULD WARM UP ENOUGH FOR A COLD RAIN OVER SOUTHERN ARKANSAS. OVER CENTRAL AND NORTHERN ARKANSAS, I SEE A WINTRY MIX OF SLEET, SNOW, AND RAIN.

THE OTHER KEY TO THIS FEATURE FOR MID WEEK IS ITS SPEED. IT WILL FLY THROUGH THE STATE SO NO MAJOR AMOUNTS ARE EXPECTED. THIS MORNINGS RUN OF THE GFS INDICATED LESS THAN A .1'' WHILE THE NAM SHOWS UP TO 1'' OVER SOUTHERN ARKANSAS OF LIQUID.

BOTTOM LINE... COLD COMES BACK TUESDAY, QUICK SHOT OF WINTRY WEATHER WEDNESDAY NIGHT AND THURSDAY WITH A VARIETY OF PRECIP. ACROSS THE STATE AND IT'S OF COURSE TOO EARLY TO KNOW FOR SURE WHO GETS WHAT.

ALSO, SUNDAY'S HIGH WAS 39 IN LITTLE ROCK. NOT A BAD FORECAST AT ALL!
