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 Jun 19, 2:06 PM CDT, 8 hours 43 minutes earlier.
Area forecast discussion, Jun 19, 2:06 PM CDT, 8 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 200 PM CDT THU JUN 19 1997 MAIN FORECAST PROBLEM...ONCE AGAIN THE DEVELOPMENT AND PROPAGATION OF MCS DEVELOPING THIS AFTERNOON OR EVENING... SURFACE...ISENTROPIC...AND THETA-E ANALYSES AT 12Z INDICATE THAT THE LOW LEVEL TEMPERATURE GRADIENT...850MB THETA-E RIDGE...AND SURFACE TROUGH COME TOGETHER JUST NORTHWEST OF BBW WITH SIGNIFICANT ISENTROPIC FORCING ON THE 310K THETA SURFACE. AS EVERYTHING SHIFTS EAST ON THE MID TROPOSPHERIC WESTERLIES AND THE SFC LOW COMES INTO NORTHWEST NEBRASKA...THE ISENTROPIC FORCING WILL INTENSIFY AND THE JUNCTION OF THE FRONT...MOISTURE RIDGE...AND SURFACE TROUGH MOVES INTO THE VICINITY OF OFK LATE THIS AFTERNOON. COMBINING THAT WITH SFC BASED LI'S IN THE -2 RANGE...WOULD EXPECT CONVECTION TO FIRE IN THE AREA. WITH MCS BACK BUILDING IN 1000-500MB THICKNESS DIFFLUENCE ALONG THE S. DAK/NEB LINE...I'M GUESSING THAT THE CONVECTIVE SYSTEM COULD BUILD BACK AS FAR AS ANW OR VTN. PRECIPITABLE WATER IN WESTERN NEBRASKA HAS DROPPED TO ABOUT 0.9 INCH TODAY FROM 1.1 YESTERDAY...BUT THAT IS STILL ENOUGH TO LIGHT OFF SOME CONVECTION IN THE SOUTHWEST PART OF THE STATE. SO SOME MENTION OF POP IS APPROPRIATE IN THE WESTERN AND SOUTHWEST ZONES IT APPEARS THAT THE AREA NORTH AND EAST OF A MRR-BBW LINE SHOULD BE HIT PRETTY HARD WITH STRONGER LANGUAGE LIKE SCATTERED THUNDERSTORMS WHILE THE REST OF THE LBF CWA COULD PROBABLY BE COVERED BY 30 OR 40 PERCENT PROBABILITIES. FOR THE REST OF THE FORECAST PERIODS...PRESENT FORECAST LOOKS GOOD PRECIPITATION WISE IN LIGHT OF ETA/NGM/AVN SOLUTIONS WHICH ARE SIMILAR. BUT...FOR TEMPERATURES...THE NGM AND AVN ARE BOTH A CATEGORY COOLER THAN THE PRESENT FORECAST INDICATES FOR FRIDAY. SO...BACKING OFF A CATEGORY IN FRIDAY'S HIGHS APPEARS TO BE APPROPRIATE. THE NGM TEMPERATURE GUIDANCE HAS BEEN DOING WELL...BUT GUIDANCE FOR VTN SEEMS TO BE ABOUT 5 DEGREES TOO LOW. AVN NUMBERS SEEM A LITTLE MORE REASONABLE. FOR LBF, FAN AND FWC ARE NEARLY IDENTICAL. HAVE EXTRAPOLATED TEMPERATURES FOR ANW,ONL,BBW FROM FWCOFK AND FANLBF (FOR VTN).
