SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
238 AM CDT TUE JUN 13 2000

ALL EYES ON FRONT AS TIMING WILL BE CRITICAL FOR CONVECTION AHEAD OF
IT AT PEAK HEATING.

FIRST OF ALL...CONVECTION HAS BLOOMED AGAIN NEAR LBF ALONG 700 MB
TROUGH...DIRECTLY NORTH OF RED WILLOW PROFILER SHOWING DUE SOUTH
WINDS AT 850 MB TAGGING 35 KTS.  WILL MONITOR THIS FOR POSSIBLE
RAMIFATIONS TO TODAYS FORECAST CLOUDS/POPS/TEMPS.

06Z SURFACE ANALYSIS SHOWED LOW PRESSURE OVER NW SDAK WITH COLD
FRONT FROM NDAK TO WY. WARM FRONTAL BOUNDARY ACROSS NE NEBR WITH
TROUGH ACROSS THE WESTERN PORTION OF THE STATE.  IMPRESSIVE UPPER
LEVEL TROUGHING SEEN ON WV IMAGERY FROM WY TO MONTANA.

MODELS ALL APPEAR TO BE A LITTLE QUICK WITH SHORT WAVE AT 6 HOURS.
ETA/AVN SOLUTION LOOKS ON TRACK FOR FRONTAL PASSAGE AS NGM TOO FAST.
APPEARS FRONT/SHORT WAVE INTERACTION SHOULD CORRESPOND TO PEAK
HEATING PERIOD OVER SE CWFA.  THIS IN LINE WITH SWODY1 AS SVR STORMS
A DEFINITE POSSIBILITY GIVEN AMOUNT OF LIFT/INSTABILITY.  WILL GO
WITH HIGHEST POPS SE FOR AFTERNOON/TONIGHT AND MENTION SVR PSBLTY.

FARTHER NORTHWEST...CANNOT RULE OUT A BRIEF PREFRONTAL TSTM BUT CHCS
ONLY SLIGHT IN THE AFTN AS PEAK HEATING NOT REACHED.  850 MB FRONT AND
UPPER TROUGH PASSAGE COULD ALSO PRODUCE SHOWERS/TSTMS TONIGHT BUT
MOISTURE ON THE WANE SO CAN ONLY GO WITH SMALL POPS.

FRONT MAKES TEMPERATURES A PROBLEM AS COMPRESSIONAL WARMING A FACTOR.
CAA DOES NOT REALLY TAKE HOLD TIL AFTER SUNSET...SO SHOULD MIX OUT
TO FAIRLY WARM TEMPS TUESDAY.  PLAN TO GO AT OR ABOVE GUIDANCE...OF
COURSE DEPENDENT ON CONVECTION OUT WEST.

TROUGH REALLY DIGS INTO UPPER MIDWEST WEDNESDAY AND THERE IS SOME
THREAT OF WRAP AROUND CLOUDS AND JUST MAYBE LIGHT RAIN OVER THE
NORTHEAST.  WILL LEAVE DRY FOR NOW BUT CLOUDS AND COOL AIR WILL BE
TAKEN INTO ACCOUNT AS WILL PROBABLY HAVE TO UNDERCUT GUIDANCE TEMPS.

LATEST ETA AND AVN BOTH EXTRAPOLATE TO A SHORT WAVE ZIPPING INTO THE
REGION FROM THE NW THU NGT/FRI.  SO WILL LEAVE PCPN MENTION IN EFP.
EXTENDED TEMP TREND LOOKS OK TOO.

.GID...NONE.
