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 Hastings, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 15, 2:49 PM CDT, 4 hours 36 minutes earlier.
Area forecast discussion, Jun 15, 2:49 PM CDT, 4 hours 36 minutes before
CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 248 PM CDT SUN JUN 15 1997 MAIN QUESTION IS WHETHER THERE WILL BE ANY CONVECTION IN THE CWA WITH FROPA. 18Z SFC CHART HAD COLD FRONT YKN-BBW-GLD WITH SEVERAL TROFS AHEAD OF IT. UEX 88D HAD AT LEAST 5 BOUNDARIES SHOWING UP WHICH MAY OR MAY NOT TRIGGER CONVECTION. 60+ DEW POINTS OVER MOST OF THE CWA WITH SLIGHTLY LESS MOISTURE WORKING ITS WAY IN FROM THE NORTH AND WEST. ALOFT CLOSED LOW REMAINS IN THE DESERT SW KICKING OUT PIECES OF ENERGY AND ANOTHER S/W MOVING ACROSS THE NRN PLAINS. HANDLING OF THE CLOSED LOW DIFFERNT IN THE MODELS TODAY WITH THE ETA MOVING IT THE FASTEST TO THE EAST. THE NGM/AVN SIMILIAR IN ITS LOCATIONS BUT THE NGM FILLS IT MORE THAN THE AVN. IN ANY EVENT NGM/AVN PATTERN PREFERRED AND BY 48 HRS THE UPPER LOW PROGGED TO BE IN THE TX P/H. AFTER NRN STREAM TROF PASSES THROUGH THE AREA THIS EVENING FLOW ALOFT BECOMES NW ACROSS THE CWA. LOOKS LIKE FRONT HANGS UP IN SRN KS/OK AND COULD BE SOME HEAVY RAINS OVER THE NEXT COUPLE OF DAYS BUT FEEL THIS WILL BE ALL SOUTH OF THE HSA. LOOKS TO ME LIKE THE HSI CWA IS PROBABLY OUT FROM UNDER THE GUN FOR ANY SEVERE WX THIS EVENING BUT JUST TO THE EAST AND SOUTH WHEN THE FRONT HITS THE 65 DEW POINTS IT COULD BE ANOTHER MATTER. PROBABLY COULD HAVE A FEW ISOLATED TRW IN THE KS CWA TONIGHT BUT FOR THE MOST PART THINK WE MAY HAVE MISSED OUT ON ANY BIG OUTBREAKS TODAY. SO CLOUDS SHOULD BE SCATTER OUT TONIGHT AND THEN MAINLY FAIR WEATHER FOR THE REMAINDER OF THE PERIOD. TEMPERATURES COOLER ON MONDAY BUT WARM UP AGAIN ON TUESDAY.
