DISCUSSION

HIGH CLOUDS ARE DRIFTING INTO OUR WESTERN COUNTIES THIS
AFTERNOON WITH MOSTLY CLEAR SKIES FARTHER EAST. TEMPERATURES ARE
GENERALLY IN THE LOW 20S ACROSS EASTERN NEBRASKA AND WESTERN
IOWA. WATER VAPOR SATELLITE IMAGERY SHOWS THE BROAD TROUGH OVER
THE EASTERN CONUS WITH US UNDER NORTHWESTERLY FLOW.
THE UPPER-LEVEL PATTERN REMAINS MESSY THROUGH THE NEXT FEW DAYS
AS A RIDGE OVER THE ROCKIES PUSHES INTO THE TROUGH TO OUR EAST
LEADING TO ENHANCEMENT IN THE POLAR JET STREAK PUSHING SOUTH
INTO THE DAKOTAS AND MINNESOTA. IT'S ULTIMATELY THE
AMPLIFICATION OF THE SUBTROPICAL JET OVER THE DESERT SOUTHWEST
THAT FINALLY PUSHES THE TROUGH OFF TO THE EAST WEDNESDAY INTO
THURSDAY. AS THIS OCCURS, A WEAK RIDGE MOVES ACROSS THE CENTRAL
PLAINS ON WEDNESDAY. THIS ALLOWS FOR WEAK WARM-AIR ADVECTION TO
CONTINUE THE WARMING TREND, WITH HIGHS IN THE UPPER 20S TO LOW
30S DURING THE AFTERNOON. THURSDAY A SHORTWAVE TROUGH IS ALLOWED
TO MOVE IN WITH THE EXIT OF THE BROAD TROUGH TO OUR EAST. THIS
DEVELOPS A SURFACE LOW OVER SOUTHEAST CO/SOUTHWEST KS AND TRACKS
IT EASTWARD ALONG ACROSS OKLAHOMA/KANSAS/MISSOURI. THIS SYSTEM
REMAINS WEAK AND DOESN'T HOLD TOGETHER TOO LONG, BUT IT WILL
ADVECT MOISTURE INTO EASTERN NEBRASKA AND WESTERN IOWA FROM THE
GULF. A FRONTOGENESIS BAND IS FORECAST TO DEVELOP ACROSS OUR
AREA NORTH OF THE LOW BRINGING 30-50% CHANCES FOR LIGHT SNOW
THROUGH THE DAY ON THURSDAY. WITH HIGH TEMPERATURES FORECAST TO
REMAIN IN THE 20S, ANYTHING THAT FALLS SHOULD JUST FALL AS SNOW.
AMOUNTS RIGHT NOW LOOK LIGHT, GENERALLY LESS THAN AN INCH, BUT
WE COULD SEE A NARROW BAND OF HIGHER AMOUNTS.
GOING INTO FRIDAY A STRONGER TROUGH PIVOTS SOUTH OUT OF CANADA
INTO THE NORTHERN PLAINS BRINGING ANOTHER SURGE OF ARCTIC AIR.
TEMPERATURES WILL FALL BACK DOWN NEAR ZERO FRIDAY MORNING WITH
HIGHS BACK IN THE TEENS FRIDAY AFTERNOON. SATURDAY MORNING LOWS
FALL EVEN FURTHER INTO THE -2 TO -8 DEGREE RANGE WITH WIND
CHILLS DROPPING TO -15 TO -20.
ANOTHER TRAILING SHORTWAVE BRINGS ADDITIONAL CHANCES (30-50%)
FOR LIGHT SNOW SATURDAY INTO SATURDAY NIGHT. THERE IS
SIGNIFICANT SPREAD IN THIS SYSTEM, SO CONFIDENCE IS LOW IN
DETAILS.
THE COLD DOESN'T STICK AROUND LONG, WITH TEMPERATURES WARMING
INTO THE 30S ON SUNDAY AND WE MAY EVEN SEE 40S ON MONDAY.
