EVENT...TSTMS DEVELOPING..POTENTIAL FOR HVY RAIN
.
SATELLITE ANALYSIS AND TRENDS...SW-NE LINES OF TCU/TSTMS HAVE BEGUN
TO DEVELOP OVER W SD AND THE NEB PANHANDLE. THE CNVTN IS STILL W OF LL
MOISTURE AXIS TO THE E. SFC DEW POINTS ARE IN THE 40'S..BUT IN MOISTURE
AXIS TO THE E..DEW POINTS JUMP INTO THE LOW 60S. BEST SFC CONVERGENCE ATTM
EXTENDS FM NE CO THRU WRN NEB..PER OBJECTIVE ANALYSIS. AND SERLY FLOW
IS NOTED FM SFC OBS AS WELL AS 850MB PROFILER WINDS FM SW NEB INTO THE
CONVERGENCE ZONE OVER W NEB/NEB PANHANDLE. ADDITIONALLY..GOES SOUNDER LI
IMAGERY SHOWS STEADY INCR IN INSTABILITY OVER THE DISCUSSION AREA...WITH
VALUES OF -8 TO -10C JUST TO THE E OF THE CNVTN. PW'S ARE UP TO 1-1.2"
E OF THE CNVTN.
.
CONUS WV IMAGERY ANIMATION SHOWS MID LEVEL MOISTURE STREAMING NEWD AHEAD
OF UPPR LOW AND NEG TILTED TROF OVER NW MX/SW US. THE LEADING EDGE OF
THE WV PLUME HAS NOW SPREAD OVER W SD AND THE NEB PANHANDLE. CONCERN FOR
THIS EVE/TONIGHT IS FOR HVY RAIN OVER THE DISCUSSION AREA. ALTHOUGH THE
DEVELOPING CNVTN IS STILL IN RELATIVELY DRY ENVIRONMENT AT THE SFC..STLT
TRENDS/PROFILERS/SFC DATA ALL POINT TWD MOISTENING UP OF THE ENVIRONMENT
AS THE HOURS PROGRESS. ESP CONCERN IS FOR WRN NEB/NEB PANHANDLE..AS DECENT
SFC CONVERGENCE MAX IS OVER THE AREA. GOES SOUNDER LOOP SHOWS PW PLUME
SPREADING NWWD FM KS TWD SW NEB. IN ADDITION.. CNVTN IS DEVELOPING OVER
NE CO..WHICH WILL ALSO FEED NEWD AND EVENTUALLY MERGE WITH CNVTN OVER NEB.
.
ND...DECENT CONVERGENCE ZONE ALSO SET UP OVER W PART OF THE STATE..WITH
MID TO UPPR 60S DEW POINTS OVER THE AREA. ALSO..NW-SE PLUME OF HIGH
PW'S EXTENDS FM S CANADA THRU NW ND THRU MN AND ALSO COINCIDES WITH
HIGH INSTABILITY AXIS. CONVERGENCE ZONE/FRONTAL BOUNDARY COMBINED WITH
FAVORABLE MOISTURE/INSTABILITY SHOULD BE FOCUS FOR DEVELOPING CNVTN LATER
THIS AFTN/TONIGHT. LATEST GOES SOUNDER CINH IMAGERY SHOWS THAT WHILE
THERE IS STILL SOME DECENT INHIBITION..CINH VALUES ARE BEGINNING TO DECR
OVER NW/W ND..WHICH SHOULD EVENTUALLY ALLOW FOR CNVCTV DEVELOPMENT. WOULD
ALSO EXPECT THAT SWRLY FLOW ALOFT WILL CARRY ANY CNVTN FM SD NEWD INTO
ND THIS EVE/TONIGHT.
