What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS North Platte, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 3:39 PM CDT, 5 hours 33 minutes earlier.
Area forecast discussion, May 22, 3:39 PM CDT, 5 hours 33 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 339 PM CDT SAT MAY 22 2010 .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT. MAIN CONCERN FOR THIS PERIOD WILL BE THE THREAT FOR SEVERE TSTM ACTIVITY. CONDITIONS VERY UNSTABLE ALONG AND EAST OF A DRY LINE WHICH EXTENDS FROM ROUGHLY VALENTINE TO JUST EAST OF MCCOOK. HAS BEEN A FEW CU DEVELOPING FROM EASTERN LINCOLN UP THOUGH CUSTER COUNTY JUST EAST OF THE DRY LINE. SFC BASED CAPES APPROACHING 5000J/KG IN THIS AREA...BUT CAP STILL EVIDENT ON LBF SPECIAL 20Z SOUNDING. LOCALLY RUN WRF MODEL DOES STILL HINT AT CONVECTION DEVELOPING IN EASTERN LINCOLN THOUGH CUSTER COUNTIES...AND UP TOWARDS ONEILL. WILL CONTINUE TO MONITOR. ANOTHER POTENTIAL FOCUS FOR STORMS WILL BE THE COLD FRONT MARCHING EAST ACROSS THE AREA MID TO LATE EVENING. THE DRY LINE WILL RETREAT WESTWARD INTO WESTERN NEB EARLY THIS EVENING...AND HAVE SOME DECENT CONVERGENCE ALONG THE BOUNDARY...AND CANNOT COMPLETELY IGNORE THE THREAT FOR CONVECTIVE DEVELOPMENT ALONG THE BOUNDARY. SUNDAY...MORE POTENTIAL FOR STORMS...ESPECIALLY BY SUNDAY EVENING. ALL MODELS INDICATE THE COLD FRONT WHICH MOVES THROUGH SATURDAY NIGHT WILL STALL ACROSS KS SUNDAY MORNING...AND THEN LIFT NORTH INTO SOUTHERN NEB VERY LATE SUNDAY AFTERNOON. TWO SCENARIOS POSSIBLE FOR SUNDAY...1) SFC BASED STORMS DEVELOPING JUST NORTH OF THE WARM FRONT ACROSS THE FAR SOUTHERN SECTIONS OF SOUTHWEST NEB DURING THE LATE AFTERNOON...AND 2) ELEVATED STORMS DEVELOPING NORTH OF THE BOUNDARY ACROSS NEARLY ALL OF WESTERN AND CENTRAL NEB FROM MID EVENING ONWARD. SPC HAS EXPANDED THE SLIGHT RISK NORTHWARD SUNDAY TO INCLUDE ALL OF WESTERN AND NORTH CENTRAL NEB. SUNDAY NIGHT...GOOD WAA AND MOISTURE ADVECTION INTO THE AREA AS WARM FRONT LIFTS NORTH THROUGH THE AREA. TSTMS SEEM LIKE A GOOD BET...WITH SFC BASED STORMS... POSSIBLE SEVERE...DURING THE EVENING ALONG AND SOUTH OF I-80 INVOF THE NORTHWARD MOVING WARM FRONT. STORMS FURTHER NORTH WILL BE MORE ELEVATED...BUT STILL COULD CONTAIN A SEVERE HAIL THREAT. .LONG TERM...MONDAY THROUGH SATURDAY... A SIGNIFICANT S/W IS SET TO EJECT RAPIDLY NE ACROSS THE NRN PLAINS MONDAY. AFTER THAT...00Z AND 12Z DETERMINISTIC AND ENSEMBLE GUIDANCE STRONGLY SUGGESTS THAT FLOW ALOFT RETROGRADES WITH 500-HPA RIDGING TAKING HOLD OVER THE HIGH PLAINS THRU AT LEAST SAT DOWNSTREAM OF PERSISTENT PACIFIC NW TROUGHING. RICH MOISTURE WILL REMAIN IN PLACE ON SOUTHERLY FLOW /INTERRUPTED ONLY BRIEFLY ON TUE/...BUT THUNDER CHANCES WILL DIMINISH TO CLIMO VALUES STARTING THU AS THE UPPER JET SHIFTS TO THE NW. THIS MEANS THE FCST IS A DRY ONE THU-SAT. MONDAY...A 110 KT JET STREAK SHIFTS NNE ACROSS THE HIGH PLAINS WITH SIGNIFICANT CYCLOGENESIS INDUCING A STOUT 45-55KT LLJ. MERIDIONAL FLOW RESULTS IN DEEP UNIDIRECTIONAL WIND PROFILES...WHICH KEEPS RICH MOISTURE IN PLACE BENEATH STEEP MID LVL LAPSE RATES. MLCAPE VALUES ARE FCST AROUND 2000 J/KG WITH MINIMAL MLCIN AND 0-6KM BULK SHEAR OF 45-55KTS...SO AN ACTIVE SEVERE EVENT COULD BE IN STORE. DEEP LAYER SHEAR VECTORS ARE ORIENTED NEARLY PARALLEL THE SFC FRONT...AND GIVEN THE LACK OF APPRECIABLE CAPPING...QUICK UPSCALE GROWTH INTO LINEAR SEGMENTS OR CLUSTERS MAY OCCUR. HOWEVER...THERE/S CERTAINLY AT LEAST SOME POTENTIAL FOR SUPERCELLS...AND THE STRONG WINDS OFF THE DECK DO RESULT IN SIGNIFICANT 0-1-KM BULK SHEAR...SO ALL MODES OF SEVERE ARE POSSIBLE. POPS WERE INCREASED INTO THE HIGH CHANCE CATEGORY IN THIS PERIOD GIVEN CONSENSUS AMONG 12Z MODEL QPF PROGS. TUESDAY-WEDNESDAY...BRIEF LOW LVL STABILIZATION IN THE WAKE OF THE FROPA MAY MAKE TUE A DRY DAY...BUT A WEAK LLJ SHIFTS THE INSTABILITY AXIS BACK NWD TUE NIGHT. MODELS KEEP THE MOIST AXIS UNCAPPED WED SO POPS WERE LINGERED RIGHT INTO THAT PERIOD...BUT FLOW ALOFT WEAKENS SUBSTANTIALLY SO THE SEVERE THREAT WILL BE ON THE WAY DOWN. THURSDAY-SATURDAY...RICH MOISTURE WILL REMAIN IN PLACE WITH SFC TD/S LIKELY IN THE LOWER/MIDDLE 60S F. IN THESE CASES...MODELS TYPICALLY OVERESTIMATE DIURNAL COOLING...WHICH APPEARS TO THE BE CASE WITH THE 00Z AND 12Z SOLUTIONS. SO...WE HAVE TRENDED MIN TEMPS UP TOWARD THE EXPECTED TD/S...BUT ONLY NUDGED MAX TEMPS TOWARD THE 12Z MODELS. && .AVIATION... VFR CONDITIONS WILL PREVAIL OVER MOST OF WESTERN AND NORTH CENTRAL NE THRU 18Z SUNDAY. HOWEVER...THE PASSAGE OF A DRYLINE AND COLD FRONT DOES YIELD A LOW PROBABILITY OF TSRA THROUGH 06 UTC...MOSTLY ALONG AND EAST OF HIGHWAY 83. THE RISK IS TOO MINIMAL TO EXPLICITLY MENTION IN THE LBF OR VTN TAFS. THERE/S THEN SOME RISK OF VFR OR MVFR CIGS DEVELOPING AFTER 06 UTC AS THE FRONT SHIFTS SOUTHEAST... BUT THAT TOO IS A LOW CONFIDENCE SCENARIO. THE CHANCES OF THOSE CIGS OCCURRING WOULD INCREASE A BIT IF MORE TSRA THAN EXPECTED DEVELOP... WHICH WOULD BOTH PUSH THE FRONT THROUGH MORE QUICKLY AND TEND TO INCREASE MOISTURE IN THE FRONT ALOFT. && .HYDROLOGY... THE NORTH PLATTE RIVER REMAINS HIGH FROM THE STATE LINE DOWNSTREAM TO LAKE MCCONAUGHY. LISCO AND LEWELLEN WILL LIKELY CREST BY SUNDAY AFTERNOON. SINCE NO HEAVY RAIN IS EXPECTED OVER THOSE SITES THE NEXT 24 HRS...LEWELLEN MAY CREST JUST BELOW FLOOD STAGE...BUT THE WARNING WILL BE CONTINUED WITH A RANGE OF CRESTS FROM 7.3 TO 7.5 PROVIDED. && .LBF WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...TAYLOR LONG TERM/AVIATION/HYDROLOGY...SCHULTZ
