The episode as NWS AMA wrote it up.
The dry spring pattern continued into the first half of April for the Oklahoma Panhandle. There were a few scattered rain events early in the month, though most areas measured less than 0.10 inches of rain through April 15th. Several widespread rain events affected the Panhandle in the second half of the month, however; and most locations ended up receiving at least 1 to 1.5 inches of rain for April. This beneficial rain fell mostly across the eastern Panhandle and southern portions of Cimarron and Texas Counties. As a result there was improvement to Severe (D2) Drought conditions in the central and eastern Oklahoma Panhandle, while conditions worsened to Extreme (D3) Drought in the western Panhandle. Guymon recorded 1.46 inches of precipitation (0.05 inches below normal) during April.
Soil moisture was rated from mostly adequate to short by the end of April. Prior to the onset of spring rains, dry and windy weather had left most soil moisture rated as short. The rain was too late to save some winter wheat, though did help to ensure a good moisture profile for spring planting of summer crops in many areas. Rangeland and pasture improved throughout the month, though cattle herd sizes remained limited due to prolonged drought and high cattle prices. Upper soil zones were mostly above 40 percent full by the end of April, with top soil in the western Panhandle in the 10 to 20 percent full range (moderate agriculturally dry). Deeper soil ranged from 30 to 50 percent of normal in the western Oklahoma Panhandle to between 70 and 100 percent of normal across the eastern Panhandle. The Palmer Drought Severity Index indicated a rating of Near Normal conditions for the Oklahoma Panhandle. No countywide or statewide burn bans were in effect.
Streamflows and reservoir levels across the Oklahoma Panhandle were below to much below normal during April, resulting in moderate to extreme hydrologic drought.
Economic losses due to the drought through April were predominantly the result of losses in winter wheat and supplemental feed for cattle on drought-thinned rangeland and pastures.

1114 PM CDT TUE MAR 31 2015
.AVIATION...
VFR CONDITIONS TO PREVAIL THROUGH THE NEXT 24 HOURS AT ALL TERMINAL.
LIGHT EASTERLY WINDS WILL SLOWLY SHIFT TO A SOUTHERLY DIRECTION BY
TOMORROW MORNING. WINDS WILL INCREASE ONCE AGAIN OUT OF THE
SOUTHWEST WITH GUSTS APPROACHING 30 KT. THESE GUSTY WINDS WILL
DIMINISH AFTER 00Z THURSDAY. A SURFACE TROUGH WILL MOVE THROUGH KGUY
TOWARDS THE END OF THIS TAF ISSUANCE TO SHIFT WINDS OUT OF THE NORTH.
THERE IS A CHANCE FOR CONVECTION TOMORROW AFTERNOON BUT CONFIDENCE ON
OCCURRENCE AT THE TERMINALS IS TOO LOW TO MENTION IN PREVAILING.

AN OUTFLOW BOUNDARY FROM CONVECTION TO THE EAST MAY REACH KAMA
BY AROUND 01Z CAUSING WINDS TO BECOME SOUTHEASTERLY AND INCREASE TO
AROUND 12 KNOTS OR LESS. AT KGUY AND KDHT WINDS WILL BE EASTERLY OR
SOUTHEASTERLY AS WELL AT GENERALLY 10 KNOTS OR LESS TONIGHT. WINDS
WILL GRADUALLY VEER AROUND AND BECOME SOUTHWESTERLY BY MORNING AND
INCREASE TOMORROW AFTERNOON WITH GUSTS OVER 20 KNOTS POSSIBLE AFTER
ABOUT 17Z. VFR CONDITIONS WILL PREVAIL. SHOWERS AND THUNDERSTORMS WILL
BE EAST OF ALL THREE TERMINALS THIS EVENING AND AGAIN TOMORROW

DISCUSSION...
PRIMARY FORECAST CONCERNS INCLUDE THUNDERSTORM POTENTIAL THROUGH THIS
EVENING AND AGAIN WEDNESDAY AFTERNOON AND EVENING...ALONG WITH
ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS WEDNESDAY AND THURSDAY.
CONVECTION IS TRYING TO GET GOING LATE THIS AFTERNOON ACROSS PORTIONS
OF THE SOUTHERN AND EASTERN TX PANHANDLE. DECENT INSTABILITY IS IN
PLACE ACROSS THE EASTERN TX PANHANDLE WHERE STRONG DIURNAL
HEATING...STEEP MID-LEVEL LAPSE RATES...AND SURFACE DEWPOINTS AROUND
50F HAVE YIELDED 0-1 KM MLCAPES OF 1000-2000 J/KG. THIS INSTABILITY
COMBINED WITH 30 KTS OF EFFECTIVE BULK SHEAR WILL SUPPORT STORM
ORGANIZATION...AND THE POTENTIAL FOR SOME SEVERE HAIL AND WINDS LATE
THIS AFTERNOON AND EVENING. THE MAIN QUESTION IS THE DEGREE OF
FORCING...WHICH REMAINS RATHER WEAK. DIURNAL HEATING HAS ERODED MUCH
OF THE CAP THIS AFTERNOON...ALTHOUGH MESOANALYSIS DATA SHOWS SOME
WEAK CIN REMAINING IN THE EASTERN PANHANDLES WHERE THE BETTER
MOISTURE/INSTABILITY EXISTS. WEAK SURFACE CONVERGENCE AND/OR WEAK
SOUTHEAST LOW-LEVEL FLOW ASSOCIATED WITH A SURFACE LOW SOUTH OF THE
AREA MAY BE ENOUGH TO AID CONVECTIVE DEVELOPMENT HOWEVER. FARTHER
WEST...DEWPOINTS HAVE MIXED INTO THE 20S AND 30S...LIMITING ANY
CONVECTIVE POTENTIAL. COULD HOWEVER SEE A VIRGA SHOWER DRIFT INTO THE
FAR NORTHWEST PANHANDLES OFF THE RATON MESA THIS EVENING. EXPECT ANY
STORMS TO DISSIPATE BY MID TO LATE EVENING AS DAYTIME HEATING IS
LOST.
ON WEDNESDAY...AN UPPER TROUGH WILL MOVE EAST ACROSS THE NORTHERN
ROCKIES AND PLAINS...WITH A TRAILING TROUGH ALONG THE WEST COAST. A
RESULTANT INCREASE IN MID/UPPER FLOW WILL PROMOTE LEE CYCLOGENESIS
OVER THE CENTRAL HIGH PLAINS WITH SURFACE TROUGHING EXTENDING SOUTH
THROUGH THE PANHANDLES. THE DRYLINE WILL MIX EASTWARD THROUGH THE
EASTERN PANHANDLES DURING THE AFTERNOON...AIDED BY DRY DOWNSLOPE
SOUTHWEST WINDS. STILL UNCERTAINTY AS TO WHETHER THE DRYLINE WILL MIX
ALL THE WAY INTO WESTERN OK BEFORE ANY STORMS INITIATE OR HANG UP IN
THE EASTERN PANHANDLES. GIVEN THIS UNCERTAINTY...HAVE INSERTED SOME
SLIGHT CHANCE POPS IN THE EASTERN ZONES WEDNESDAY AFTERNOON AND
EVENING. VERY STRONG HEATING WILL LIKELY ERODE MUCH IF NOT ALL OF
THE CAP...BUT FORCING AGAIN APPEARS WEAK AND NOT WELL-FOCUSED. THE
DRYLINE LOOKS FAIRLY DIFFUSE...ALTHOUGH SOME WEAK LOW-LEVEL
CONVERGENCE IS PROGGED...BUT THE STRONGER UPPER DYNAMICS WILL REMAIN
TO OUR NORTH. IF STORMS ARE ABLE TO FORM IN THE EASTERN
PANHANDLES...EXPECTED INSTABILITY AND SHEAR SUPPORT SOME STRONG TO
MARGINALLY SEVERE CONVECTION. WEST OF THE DRYLINE...FIRE WEATHER
CONCERNS WILL BE THE STORY /DETAILS BELOW/. HIGH TEMPERATURES WILL
LIKELY APPROACH RECORDS AS THEY SOAR INTO THE UPPER 80S TO LOWER 90S.
A COLD FRONT WILL MOVE THROUGH WEDNESDAY NIGHT...USHERING IN SLIGHTLY
COOLER CONDITIONS FOR THURSDAY. A MUCH STRONGER COLD FRONT WILL COME
THROUGH THURSDAY NIGHT...WITH HIGHS ONLY EXPECTED TO REACH THE 50S
AND LOWER 60S ON FRIDAY AS A 1025 MB SURFACE HIGH BUILDS IN BEHIND
THE FRONT. COULD SEE A FEW RAIN SHOWERS ACROSS THE OK PANHANDLE
THURSDAY NIGHT AS DYNAMICS WITH AN UPPER TROUGH SCRAPE THE AREA. LOWS
EXPECTED TO FALL INTO THE 30S IN MOST LOCATIONS FRIDAY NIGHT...WITH A
FROST OR FREEZE POSSIBLE FOR AT LEAST PARTS OF THE AREA.
TEMPERATURES WILL REBOUND OVER THE WEEKEND INTO EARLY NEXT WEEK AS
QUASI-ZONAL UPPER FLOW/LOW-AMPLITUDE RIDGING EVENTUALLY GIVES WAY TO
SOUTHWEST FLOW DOWNSTREAM OF A WESTERN UPPER TROUGH. IT LOOKS LIKE
ANY THUNDERSTORM CHANCES DURING THIS TIME WILL REMAIN EAST OF THE
PANHANDLES.
KB
FIRE WEATHER...
ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED ACROSS
WESTERN AND CENTRAL PORTIONS OF THE PANHANDLES ON WEDNESDAY.
TEMPERATURES WILL WARM SOME 20 DEGREES ABOVE AVERAGE /AND NEAR RECORD
VALUES/ WITH A PRONOUNCED THERMAL RIDGE IN PLACE...LEADING TO RELATIVE
HUMIDITIES OF 8 TO 15 PERCENT WEST OF THE DRYLINE. SOUTHWEST WINDS OF
15 TO 25 MPH WITH HIGHER GUSTS MAY BE SOMEWHAT MARGINAL ACROSS PARTS
OF THE AREA FOR CRITICAL FIRE WEATHER CONDITIONS DUE TO A SURFACE
TROUGH ACROSS THE AREA...BUT THIS WILL BE OFFSET SOME BY THE VERY
WARM AND DRY CONDITIONS...THUS A FIRE WEATHER WATCH HAS BEEN ISSUED.
ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS WILL LIKELY DEVELOP
ACROSS WESTERN PORTIONS OF THE TEXAS PANHANDLE AGAIN ON THURSDAY. A
STRONGER COLD FRONT WILL MOVE THROUGH THURSDAY NIGHT...BRINGING A
WIND SHIFT TO THE NORTH BUT ALLEVIATING FIRE WEATHER CONDITIONS FOR
FRIDAY. HOWEVER...A RETURN TO WARM...DRY...BREEZY CONDITIONS IS
EXPECTED OVER THE WEEKEND INTO EARLY NEXT WEEK...BRINGING A RETURN OF
FIRE WEATHER CONCERNS.
