Original Post:
The ongoing blizzard in the Texas panhandle is threatening to break some all-time Texas snowfall records. These are the current snowfall records at Amarillo, from the National Weather Service:

Max for 24 hours: 20.6 inches on March 25-26, 1934
Max for a single storm: 20.6 inches on March 25-26, 1934
Max for one month: 28.7 inches in February 1903
Max measured snow depth: 17.0 inches on February 26, 1903
Max for a season: 50.9 inches in 1918-19

The NWS at Amarillo reports:

GOING FORECAST STILL ON TRACK. THE NWS OFFICE NOW HAS OVER 13 INCHES
ON THE GROUND WITH 3-4 FOOT DRIFTS AND A MAX GUST TO 58 MPH. THE SE
TX PANHANDLE HAS BEEN SLOW TO FILL IN WITH SNOW AFTER THE
THUNDERSTORMS THAT DROPPED HEAVY RAIN LAST NIGHT AND THESE AREAS
MIGHT END UP WITH AMOUNTS CLOSER TO THE 8 INCH SIDE THAN THE 14 INCH
SIDE OF THEIR RANGE. AT THE END OF THE DAY...THE HEAVIEST TOTALS
WILL ALMOST CERTAINLY BE ALONG A PALO DURO CANYON TO AMARILLO TO
STINNETT TO PERRYTON LINE.

SOME RECORDS SEEM TO BE IN A PRECARIOUS POSITION TODAY. THE FIRST IS
AN ALL-TIME 24 HOUR SNOWFALL RECORD AT AMARILLO OF 20.6 INCHES FROM
MARCH 25-26 1934. WE WILL LIKELY GET VERY CLOSE OR SURPASS THIS
NUMBER BY THIS AFTERNOON.

THE OTHER IS THE ALL-TIME STATE OF TEXAS 24 HOUR SNOWFALL RECORD OF
25 INCHES IN FOLLETT SET MARCH 28 2009. SOMEWHERE IN THE
PERRYTON/STINNETT/BORGER/AMARILLO AREA COULD APPROACH THIS VALUE BY
THIS AFTERNOON.
