TSRA FIRING IN SW CWA HAS PREVENTED ME FROM GETTING AS DOWN AND
DIRTY IN MODEL ANLYS THAT I WOULD HAVE LIKED...SO THIS WILL BE SHORT
AND SIMPLE. CURRENTLY STORMS ARE FIRING ON INSTABILITY AXIS OF LIS
AROUND ZERO AS INDICATED ON LATEST MSAS DATA. ALSO APPEARS TO BE
FIRING ON NOSE OF 8H JET PUSHING INTO STATE. ALSO...7H SHORT WAVE
MOVING THROUGH ALOFT AIDING IN LIFT. THESE SCT TSRA SHOULD MOVE OFF
OR DISSIPATE BY MORNINGS END...BUT NOT WITHOUT LOADING UP LOWER
LAYERS WITH PLENTY OF MOIST. STALLED COLD FRONT OUT WEST WILL BEGIN
TO MOVE EAST AS 5H VORT MAX SLIDES THROUGH. SFC LOW TAKES SHAPE ON
TAIL OF COLD FRONT AND BEGINS TO MOVE NORTHEAST...BRINGING HIGHER
DWPT AIR INTO REGION. VERY WARM 7H TEMPS OF 12-14 DEGREES C WILL
PROVIDE CAPPING FOR SOUTHERN SD THROUGH MOST OF DAY...BUT COLD AIR
BEGINS TO INVADE FAR WESTERN SD BY 00Z WHICH WILL ERODE CAP FROM
WEST. AGAIN...HODOGRAPHS FROM AROUND CWA SHOW CLASSIC SUPERCELL
SHAPE FROM 00-06Z TUESDAY WITH A LOT OF SHEAR IN THE LOWER GATES.
ALSO CONCERNED ABOUT THE PSBLTY OF HEAVY RAIN. PWATS BY 06Z RANGE
FROM 1.25 TO 1.50 INCHES. WILL MENTION SVR FOR TNT ALL AREAS...AND
LATE THIS AFTERNOON FOR KPIR AREA. CHANCE OF SHOWERS STILL LOOKS
GOOD FOR TUESDAY...BUT PERHAPS MORE TOWARD MORNING. WONT GET CUTE
AND TRY TO TIME...BUT WILL BROADBRUSH WITH POPS FOR THE WHOLE DAY.

.ABR...NONE.
