The episode as NWS IWX wrote it up.
A moderately unstable, but poorly sheared environment was in place across the region. A weak disturbance aided in widely scattered thunderstorms. One thunderstorm produced localized wind damage in northern Indiana.
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 Northern Indiana wrote its last area forecast discussion before the first event at May 26, 2:35 PM EST, 2 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 335 PM EDT MON MAY 26 2014 .SYNOPSIS... ISSUED AT 335 PM EDT MON MAY 26 2014 HIGH PRESSURE WILL CONTINUE TO SHIFT EAST AHEAD OF AN APPROACHING UPPER LEVEL DISTURBANCE AND SURFACE COLD FRONT. INCREASING CLOUDS AND CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BE IN STORE THIS EVENING WITH AN EVEN BETTER CHANCE FOR THUNDERSTORMS TOMORROW AFTERNOON. LOW TEMPERATURES WILL ONLY DROP INTO THE MID AND UPPER 60S TONIGHT WITH HIGHS IN THE LOW TO MID 80S AGAIN TOMORROW. && .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 335 PM EDT MON MAY 26 2014 OHIO VALLEY REMAINS LARGELY UNDER THE INFLUENCE OF EXPANSIVE RIDGING ALOFT AHEAD OF SOUTHERN PLAINS CUTOFF LOW. DESPITE THIS FACT...A WEAK COLD FRONT EXTENDING FROM A SURFACE LOW OVER QUEBEC WILL GRADUALLY SETTLE SOUTH ACROSS THE GREAT LAKES TONIGHT AND TOMORROW. MIDLEVEL HEIGHT FALLS/CVA ARE DISPLACED WELL TO THE NORTHEAST BUT STABLE LAKE AGGREGATE WILL HELP NUDGE THIS COLD FRONT SOUTH. MEANWHILE...A VERY HIGH THETA-E AIRMASS IS BEING ADVECTED INTO THE REGION FROM THE SOUTHERN PLAINS AND WESTERN GULF. A COMPARISON OF THE 12Z KILX AND KDTX SOUNDINGS ILLUSTRATES THIS ONGOING MOISTURE SURGE. LOCAL PW VALUES ARE EXPECTED TO APPROACH OR EXCEED 1.75 INCHES BY LATER TONIGHT AND PERSIST THROUGH TOMORROW. AFTER A SLOW START THIS MORNING...SURFACE DEWPOINTS HAVE FINALLY SURGED INTO THE LOW/MID 60S ACROSS OUR AREA. LATEST SPC/RAP MESOANALYSIS INDICATES AROUND 1000 J/KG OF MLCAPE FINALLY NOSING INTO OUR CWA DESPITE PALTRY MIDLEVEL LAPSE RATES. THE PROBLEM HERE REMAINS A LACK OF ANY SYNOPTIC SUPPORT/TRIGGERING MECHANISM. CONVERGENT BOUNDARY REMAINS WELL TO OUR NORTH WITH RIDGE AXIS FIRMLY IN PLACE OVER OUR AREA. THUNDERSTORM CHANCES THROUGH THE EVENING WILL DEPEND ON FINER SCALE DETAILS SUCH AS POTENTIAL OUTFLOW BOUNDARIES FROM UPSTREAM CONVECTION. LATEST HRRR GENERATES SOME VERY ISOLATED CONVECTION IN OUR WESTERN COUNTIES AROUND 22Z BUT SUGGESTS THE BEST POTENTIAL FOR RAIN WILL BE AFTER 00Z WHEN WHATEVER IS LEFT OF CONVECTION OVER WESTERN ILLINOIS FINALLY WASHES INTO OUR CWA. WITH THE LOSS OF DAYTIME HEATING THIS ACTIVITY WILL LIKELY BE WEAKENING SUBSTANTIALLY BY THE TIME IT REACHES US THOUGH. WILL MAINTAIN LOWER END CHANCE POPS WITH THE HIGHEST VALUES IN OUR WESTERN COUNTIES. IN VERY SUMMER-LIKE FASHION...EXPECT "POPCORN" THUNDERSTORMS WITH VERY LOW SEVERE RISK GIVEN LIGHT WINDS ALOFT/LIMITED SHEAR. BRIEF HEAVY RAIN WILL PROBABLY BE THE BIGGEST THREAT WITH SLOW STORM MOTION...HIGH MOISTURE CONTENT...AND DEEP WARM CLOUD LAYER. SUBTLE HEIGHT FALLS/VORTICITY MAXIMA WILL THEN APPROACH THE REGION LATE TONIGHT. DIURNAL STABILIZATION WILL PREVENT ANY SURFACE BASED CONVECTION BUT FORECAST SOUNDINGS INDICATE ENOUGH ELEVATED INSTABILITY TO SUPPORT A FEW LINGERING SHOWERS/THUNDERSTORMS THROUGH THE MORNING HOURS. COVERAGE EXPECTED TO BE LOW HOWEVER. MUCH BETTER CHANCES FOR RAIN/STORMS WILL ARRIVE TOMORROW AFTERNOON AS FRONTAL BOUNDARY APPROACHES AND TAKES ADVANTAGE OF VERY MOIST AND MARGINALLY UNSTABLE AIRMASS IN PLACE. EXPECT HIGH SURFACE DEWPOINTS AND LITTLE TO NO CAPPING INVERSION TO SUPPORT NUMEROUS PULSE STORMS FROM LATE MORNING THROUGH THE EVENING. MLCAPE VALUES ARE LOW...GENERALLY 1000 J/KG OR LESS...AND THERE IS VIRTUALLY NO SHEAR TO HELP ORGANIZE ANY SIGNIFICANT UPDRAFTS THAT DO MANAGE TO DEVELOP. SEVERE WEATHER RISK IS THEREFORE LOW BUT ONCE AGAIN LOCALIZED HEAVY RAIN WILL BE POSSIBLE...ESPECIALLY GIVEN INCREASED POTENTIAL FOR BACK-BUILDING AND TRAINING STORMS. && .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 335 PM EDT MON MAY 26 2014 SHRTWV OVER ONTARIO MOVG THROUGH TOP OF WRN GRTLKS RIDGE THIS AFTN EXPECTED TO DROP SEWD TO THE ERN GRTLKS BY TUE EVE. ASSOCIATED SFC CDFNT TRAILING WSW THROUGH MN WILL BECOME MORE E-W ORIENTED BY THE TIME IT REACHES OUR CWA TUE NGT... THEN MOVE SLOWLY SOUTH ACROSS OUR AREA THROUGH WED NGT. SCT MAINLY AFTN/EVE CONVECTION EXPECTED IN THE VCNTY OF THE FRONT AS IT MOVES THROUGH. INITIALLY WK DRY AIR PUSH BEHIND THE FRONT SO SOME DIURNALLY DRIVEN LAKE BREEZE CONVECTION PSBL EVEN AFTER THE FRONT MOVES TO CENTRAL IN/OH. VERY WK FLOW/MOIST AIRMASS AND EFFICIENT RAINFALL PROCESSES SUGGEST SOME LOCALLY HEAVY RAINFALL PSBL AS THE FRONT MOVES THROUGH WED AFTN/EVE WHEN INSTABILITY MAXIMIZED. FOR THE EXTENDED FCST... RIDGING EXPECTED TO STRENGTHEN OVER CENTRAL CONUS/CANADA AGAIN THU-FRI AS WEST COAST TROF DEEPENS. RIDGE EXPECTED TO MOVE EAST ACROSS THE GRTLKS OVER THE WEEKEND AS A RATHER STRONG SHRTWV LIFTS NE OUT OF THE WRN TROF. MEDIUM RANGE MODELS HAVE SGFNT DIFFERENCES ON TIMING OF THIS SYSTEM... BUT STILL APPEARS IT MAY IMPACT THE AREA WITH TSTMS AND A FROPA IN THE SUNDAY-MONDAY TIMEFRAME. TEMPS SHOULD WARM WELL ABOVE NORMAL AGAIN OVER THE WEEKEND AS THE UPR RIDGE MOVES OVERHEAD AND SOUTHERLY SFC WINDS DEVELOP ON BACKSIDE OF SFC RIDGE... WITH FROPA LOWERING TEMPS BACK CLOSE TO NORMAL EARLY NEXT WEEK. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON) ISSUED AT 125 PM EDT MON MAY 26 2014 SURFACE DEWPOINTS HAVE JUMPED TO AROUND 60F ACROSS NORTHERN INDIANA IN THE PAST FEW HOURS. EXPECT CONTINUED WARM/MOIST AIR ADVECTION AND STRONG DIABATIC HEATING TO SUPPORT INCREASINGLY UNSTABLE CONDITIONS THIS AFTERNOON. LACK OF ANY SYNOPTIC TRIGGER WILL KEEP THUNDERSTORMS SPORADIC AND DISORGANIZED GIVEN LACK OF SHEAR ALOFT. THIS MAKES NAILING DOWN AN EXACT TIMEFRAME FOR THUNDERSTORMS AT THE TERMINALS DIFFICULT. WILL THEREFORE HOLD WITH VCTS THROUGH THE BULK OF THE EVENING HOURS AND WILL AMEND AS NECESSARY ONCE CONVECTIVE TRENDS ARE CLEARER. EXPECT THUNDERSTORMS TO DISSIPATE LATER TONIGHT BUT ANOTHER ROUND WILL BE POSSIBLE TOMORROW WITH INCREASED COVERAGE DUE TO APPROACHING WEAK COLD FRONT. && .IWX WATCHES/WARNINGS/ADVISORIES...
