What happened

The episode as NWS AMA wrote it up.

A cold post-frontal airmass was well established across the Oklahoma Panhandle, and allowed temperatures to drop below freezing from the evening hours of the 23rd through the morning hours of the 24th. The subfreezing temperatures threatened sensitive vegetation during the early growing season. Morning lows on the 24th ranged from 15 degrees at Boise City (Cimarron County) to 23 degrees at Slapout (Beaver County). Temperatures quickly warmed above freezing by 9:45 AM CST on the 24th.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Amarillo, TX wrote its last area forecast discussion before the first event at Apr 23, 5:19 PM CST, 1 hour 16 minutes earlier.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
619 PM CDT TUE APR 23 2013

.AVIATION...
FOR THE 00Z TAFS...ANY REMAINING MVFR CEILINGS SHOULD RISE OR
DISSIPATE WITHIN THE NEXT FEW HOURS. AFTER THAT...SHOULD SEE VFR
CONDITIONS FOR THE REMAINDER OF THE TAF PERIOD. WINDS WILL SHIFT FROM
NORTHERLY TO NORTHWESTERLY TO SOUTHWESTERLY...BUT SHOULD REMAIN BELOW
10KT FOR MUCH OF THE TAF PERIOD. DEPENDING ON WHERE THE SURFACE LOW
ENDS UP...COULD EVEN SEE VARIABLE WIND DIRECTION AT KAMA FOR MUCH OF
THE DAY AFTER 12Z.

.PREV DISCUSSION... /ISSUED 347 PM CDT TUE APR 23 2013/

DISCUSSION...
THROUGH TONIGHT: DUE TO STRONG COLD AIR ADVECTION AND EXTENSIVE LOW
CLOUDS, HIGH TEMPERATURES TODAY HAVE BEEN AN ASTOUNDING 35 DEGREES
BELOW NORMAL! THESE CLOUDS ARE EXPECTED TO DISSIPATE EARLY THIS
EVENING AS DRIER AIR FILTERS INTO THE AREA. WINDS WILL ALSO BECOME
LIGHT OVERNIGHT AND SHIFT TO THE WEST. DUE TO THE CLEARING SKIES AND
LIGHT WINDS, WE HAVE HIGH CONFIDENCE THAT JUST ABOUT EVERY LOCATION
IN OUR AREA WILL EXPERIENCE ANOTHER FREEZE. HOWEVER, WE HAVE SOME
CONCERN THAT TONIGHT'S LOWS MAY NOT BE AS COLD AS WE'RE FORECASTING
DUE TO THE WEAK DOWNSLOPE WIND COMPONENT. THERE IS A SMALL CHANCE
THAT FREEZING FOG MAY DEVELOPING IN THE EASTERN HALF OF THE
PANHANDLES AFTER 2 AM, BUT THE DOWNSLOPING WINDS ARE NOT A
CLIMATOLOGICALLY FAVORABLE DIRECTION FOR FOG FORMATION IN OUR AREA.
THEREFORE, WE KEPT ANY MENTION OF THIS OUT OF THE FORECAST. A WEAK
SHORTWAVE TROUGH WILL ALSO PASS OVER THE AREA TONIGHT AND MAY SQUEEZE
OUT JUST ENOUGH MOISTURE FOR A FEW FLURRIES, BUT WITH THE LOW-LEVELS
REMAINING FAIRLY DRY, WE DIDN'T MENTION THIS EITHER.

WEDNESDAY-WEDNESDAY NIGHT: WINDS WILL SHIFT AROUND TO THE SOUTH WITH
HIGHS REBOUNDING INTO THE 50S AND 60S. THERE COULD BE A FEW ISOLATED
LOCATIONS THAT DROP AT OR SLIGHTLY BELOW FREEZING WEDNESDAY NIGHT,
BUT CONFIDENCE OF A WIDESPREAD FREEZE IS PRETTY LOW.

THURSDAY-FRIDAY NIGHT: TEMPERATURES WILL FURTHER REBOUND ON THURSDAY
WITH HIGHS IN THE 60S AS SOUTHERLY WINDS INCREASE. MOISTURE WILL
SLOWLY ADVECT NORTHWARD OVERNIGHT AS A SHORTWAVE TROUGH APPROACHES
FROM THE WEST. WE KEPT A MENTION OF THUNDERSTORMS IN THE FORECAST,
BUT VERY LIMITED INSTABILITY WILL BE PRESENT, ESPECIALLY THURSDAY
NIGHT. THUNDERSTORM CHANCES WILL SHIFT TO THE EASTERN PANHANDLES ON
FRIDAY AND SHOULD BE EAST OF THE ENTIRE AREA BY EARLY FRIDAY EVENING.

SATURDAY-SUNDAY NIGHT: THERE IS A POSSIBILITY OF THUNDERSTORMS BOTH
DAYS, WITH SUNDAY APPEARING TO BE THE BETTER DAY FOR STORMS CHANCES
AHEAD OF A PSEUDO-DRYLINE. OF NOTE, IT ALSO LOOKS LIKE WE'LL SEE OUR
WARMEST LOW TEMPERATURES OF THE YEAR THIS WEEKEND WITH SOME
LOCATIONS OFF THE CAPROCK POSSIBLY STAYING IN THE 60S.

MONDAY-TUESDAY: EVEN MORE OPPORTUNITIES FOR THUNDERSTORMS WILL BE IN
THE FORECAST THESE TWO DAYS. IT LOOKS LIKE THE EASTERN PANHANDLES
WILL BE MOST FAVORED ON MONDAY WITH CHANCES POSSIBLE AREAWIDE ON
TUESDAY. DESPITE A FAVORABLE PATTERN FOR THUNDERSTORMS, CHANCES FOR
SEVERE WEATHER MAY ACTUALLY BE DIMINISHED SOMEWHAT DUE TO THE MAIN
BELT OF WESTERLIES REMAINING TO OUR NORTH. THIS WILL RESULT IN WEAK
DEEP LAYER SHEAR AND LIMIT UPDRAFT ORGANIZATION/PERSISTENCE. HOWEVER,
TIMING INDIVIDUAL SHORTWAVE TROUGHS THAT COULD ENHANCE DEEP LAYER
SHEAR ON THE MESOSCALE CANNOT BE RESOLVED THIS FAR IN ADVANCE, SO
IT'S POSSIBLE WE COULD SEE SOME SEVERE WEATHER EARLY NEXT WEEK. IF
NOTHING ELSE, ANY STORMS THAT DEVELOP IN THE WEAK STEERING FLOW WILL
HAVE THE OPPORTUNITY TO PRODUCE LOCALLY HEAVY RAINFALL. WE'LL KEEP
OUR FINGERS CROSSED THAT THIS PATTERN WILL ACTUALLY VERIFY.

FIRE WEATHER...
NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED
WEDNESDAY THROUGH FRIDAY AS WINDS AND RELATIVE HUMIDITY VALUES WILL
NOT BE ALIGNED. ELEVATED FIRE WEATHER CONDITIONS MAY RETURN ON
SATURDAY THROUGH SUNDAY AS SOUTHERLY WINDS INCREASE BEHIND THE
DRYLINE.
