The episode as NWS AMA wrote it up.
Drought conditions across the Oklahoma Panhandle worsened due to limited precipitation during the month of May. The entire Oklahoma Panhandle now falls with Exceptional (D4) drought. While some precipitation occurred during the month of May, Guymon only recorded 0.16 inches of precipitation (2.28 inches below normal). The month was the 47th warmest and 4th driest May on record for the Oklahoma Panhandle.
Limited dormant fuels remain in prime condition for the spread of fires across the Panhandle. The Keetch-Byram Drought Index remained steady state for the month of May with Texas County in the 600 to 800 range, while the remainder of the Oklahoma Panhandle remains in the 400 to 600 range.
The sparse precipitation for the month and several freezes severely impacted developing crops. The Palmer Drought Severity Index for the month of May showed a degradation of conditions across the Panhandle with the entire Panhandle now rated as Severe Drought. Water watches remain in effect for several public water systems through May while voluntary to mandatory water restrictions have been enacted.
Economic losses due to the drought through May were estimated near $25 million (D4) a county, and were predominately the result for poor growth of developing crops, heavy supplemental watering, and supplemental feed for cattle in pastures and rangeland.

PREV DISCUSSION... /ISSUED 407 PM CDT TUE APR 30 2013/
DISCUSSION...TONIGHT THROUGH TUESDAY
FORECAST CONFIDENCE REMAINS BELOW NORMAL ON MANY FRONTS (LITERALLY).
A SIGNIFICANT AND ANOMALOUS LATE SPRING STORM SYSTEM WILL AFFECT THE
PANHANDLES BEGINNING LATE TONIGHT. THERE ARE MULTIPLE HAZARDS WITH
THIS SYSTEM, INCLUDING:
1) POTENTIAL FOR ACCUMULATING SNOWS AND EVEN POSSIBLE NEAR BLIZZARD
CONDITIONS IN THE NE PANHANDLES LATE WED NIGHT/EARLY THU.
2) VERY STRONG NORTHERLY WINDS BEGINNING MID MORNING WED AND LASTING
THROUGH THU THAT WILL AT SOME POINT LIKELY REACH WIND ADVISORY
CRITERIA.
3) MULTIPLE FREEZES AND A LIKELY HARD FREEZE FOR SOME WED NIGHT
AND/OR THU NIGHT.
THE DETAILS:
1) ACCUMULATING SNOW POTENTIAL.
DETAILED SOUNDING ANALYSIS OF MULTIPLE MODELS REVEALS A REAL THREAT
FOR ACCUMULATING SNOWS IN AN AREA GENERALLY CONFINED BY PAMPA ON THE
SW, GUYMON ON THE NW, AND WHEELER ON THE SE. IT APPEARS AS THOUGH
INITIALLY DRY MID LEVELS WILL COOL TO SATURATION AFTER MIDNIGHT WED
NIGHT, WITH THE ENTIRE COLUMN BELOW FREEZING BY ROUGHLY 09-10Z THU.
FROM THIS POINT UNTIL ABOUT 14Z, ASCENT DOWNSTREAM OF A DIGGING
SHRTWV AND THE EXIT REGION OF A CURVED UPR JET WILL PROVIDE A WINDOW
FOR MODERATE PRECIP. THIS WINDOW WILL FAVORABLY ALIGN TEMPORALLY WITH
THE COOLEST PART OF THE DAY AND THEREFORE ACCUMULATING WET AND HEAVY
SNOWS OF 1 TO 3 INCHES DO APPEAR POSSIBLE. THOUGH THESE AMOUNTS ARE
NOT ALL THAT IMPRESSIVE, WINDS WILL LIKELY BE HOWLING DURING THIS
PERIOD...POTENTIALLY CREATING NEAR BLIZZARD OR EVEN BLIZZARD
CONDITIONS. THIS PERIOD WILL BE WATCHED CLOSELY, BUT THE SEEMINGLY
UNLIKELY POSSIBILITY OF EVERYTHING LINING UP FOR ACCUMULATING SNOWS
SEEMS TO BE TRENDING TOWARD THE MOST LIKELY SOLUTION.
2) WINDS...
STRONG NORTHERLY WINDS WILL BEGIN TMRW IN THE MID MORNING AND STAY
CONTINUOUSLY STRONG UNTIL THU EVENING. THE STRONGEST PERIOD OF WINDS
WILL LIKELY BE FROM WED EVENING THROUGH EARLY THU MORNING. THIS
WOULD BE THE MOST LIKELY PERIOD FOR A POTENTIAL WIND ADVISORY, BUT
WILL ALLOW ANOTHER RUN OF MODELS TO COME IN BEFORE PULLING THE
TRIGGER ON A WIND ADVISORY.
3) FREEZING TEMPS...
IT APPEARS MOST OF THE PANHANDLES WILL SEE A FREEZE ONE OR BOTH
NIGHTS (WED NIGHT AND THU NIGHT). SOME RAW DATA AND FORECAST
SOUNDINGS ARE EVEN INDICATING TEENS IN THE NW PANHANDLES THU NIGHT
IF WEST WINDS STAY LIGHT ENOUGH TO PRECLUDE DOWNSLOPE WARMING. THE
FREEZE WATCH HAS BEEN CONTINUED.
THE REST OF THE PERIOD...
DRY WEATHER IS EXPECTED AS TEMPERATURES LABOR TO SLOWLY REBOUND BACK
TOWARD NORMAL BY MONDAY.

AFTER ELEVATED FIRE WEATHER CONDITIONS DIMINISH THIS EVENING...NO
