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.

Area forecast discussion, Apr 21, 8:34 PM CDT, 7 hours 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND TX
831 PM CDT SUN APR 21 1996

CURRENT FORECASTS SEEM TO BE ON TRACK.  HOWEVER... AM CONCERNED
ABOUT DRYLINE MOVING THROUGH PORTIONS OF THE FA BEFORE FROPA LATER
TONIGHT.  IF THIS HAPPENS... WIND FORECASTS WILL BE ABOUT 90 DEGREES
OFF.

01Z SURFACE ANALYSIS SHOWS FROPA IN THE NORTHERN PANHANDLE WITH 15
TO 20 KNOT WINDS BEHIND IT.  KMAF 88D SHOWS DRYLINE CREEPING BACK
INTO SOUTHERN PORTIONS OF THE PERMIAN BASIN... PRESENTLY EXTENDING
FROM JUST WEST OF FST... TO NORTH OF BIG LAKE AND NEAR STERLING
CITY.  THE DRYLINE IS APPEARS TO BE MOVING NORTHWEST AT ABOUT 15
KNOTS.  ANOTHER MORE SUBTLE BOUNDARY IS PUSHING SOUTHWEST... THIS
BOUNDARY PUSHED THROUGH MAF JUST BEFORE THE HOUR AND SWITCHED OUR
WINDS TO THE WEST.

BELIEVE IF DRYLINE MAKES IT THROUGH THE PERMIAN BASIN LATER TONIGHT
MOISTURE WILL BE TOO SHALLOW FOR ANY ORGANIZED CONVECTIVE ACTIVITY.
SO CURRENT DRY FORECASTS SHOULD BE OKAY AS WELL.  21/12Z MODEL RUNS
DO KEEP NICE PVA OVER THE AREA THROUGH 22/12Z.

KMAF 88D VWP SHOWS WINDS FIELD LOOSENING ABOVE SURFACE OVER THE
PERMIAN BASIN... THEREFORE WINDS SHOULD DIE DOWN BEFORE FROPA
ARRIVES TO CURRENT FORECASTS VALUES. 0 HOWEVER... IF DRYLINE PUSHES
THROUGH MAY SEE SOUTH TO SOUTHEAST WINDS AT 10 TO 20 AND GUSTY.
WILL BE CANCELLING HIGH WIND WARNING FOR GDP SHORTLY.

OTHERWISE... CURRENT FORECASTS SEEMS ON TRACK.
