Wintry mix expected for Friday, Friday night in Joplin area

(From the National Weather Service)

SUMMARY...LOW PRESSURE WILL MOVE INTO THE SOUTHERN PLAINS ON
FRIDAY. MOISTURE AND LIFT AHEAD OF THE LOW WILL SPREAD RAPIDLY
NORTHEAST INTO THE REGION FRIDAY MORNING. WHILE WARMER
TEMPERATURES ARE ALSO EXPECTED TO SPREAD INTO THE REGION...SOME
AREAS WILL STILL BE COLD ENOUGH TO SEE THE POTENTIAL FOR SOME
LIGHT FREEZING RAIN ACCUMULATION OR POSSIBLY SOME LIGHT SLEET OR
SNOW IN SOME AREAS.

WARMER TEMPERATURES WILL SPREAD INTO THE REGION BY EARLY
AFTERNOON WITH MOST AREAS SEEING TEMPERATURES ABOVE FREEZING. BY
FRIDAY NIGHT...COLDER TEMPERATURES MAY AGAIN ALLOW ANY
PRECIPITATION TO FALL AS A WINTRY MIX OF SNOW AND FREEZING
DRIZZLE.

TIMING AND AREAS AFFECTED...PRECIPITATION WILL SPREAD INTO FAR
SOUTHWEST MISSOURI AND SOUTHEAST KANSAS BY 7 AM FRIDAY
MORNING...THEN SPREAD QUICKLY NORTHEAST THROUGH MUCH THE AREA BY
9 AM TO 11 AM. BY EARLY TO MID AFTERNOON MOST OF THE PRECIPITATION
WILL FALL AS RAIN...BUT AFTER 6 PM FRIDAY EVENING TEMPERATURES
WILL AGAIN COOL ENOUGH FOR SOME AREAS TO SEE A WINTRY MIX.

ACCUMULATION...OVERALL ICE ACCUMULATION WILL GENERALLY BE A TENTH
OF AN INCH OR LESS WITH THE BEST CHANCES FOR ICE ALONG THE HIGHWAY
60 CORRIDOR FROM THE SPRINGFIELD AREA AND POINTS EAST. THE BEST
CHANCES FOR LIGHT ACCUMULATING SNOW...UP TO AN INCH...WILL BE IN
CENTRAL MISSOURI.

CONFIDENCE AND POTENTIAL IMPACTS...PRECIPITATION TYPE WILL BE
GREATLY DEPENDENT ON TIMING ALONG WITH TEMPERATURES AT THE
SURFACE AND ALOFT. A SMALL CHANGE IN PREDICTED TEMPERATURES CAN
AND WILL LEAD TO CHANGES IN THE FORECAST. THERE ARE ENOUGH
INDICATIONS THAT SOME ROAD SURFACES...ESPECIALLY ELEVATED
SURFACES...MAY BE AFFECTED BY LIGHT ICING ON FRIDAY MORNING. A
WINTRY MIX MAY ALSO AFFECT TRAVEL FRIDAY NIGHT.
