AMA WITH 3500 PLUS CAPE...NEG 10 TO NEG 12 LI...DEW POINTS IN THE
60S AND A 15 TEMP AT 700. BEGINNING TO SEE A FEW CU WEST AND A
LITTLE BETTER STUFF DISTANT NW THE OTHER SIDE OF CAO.
QUESTION FOR TONIGHT WILL BE IF AND HOW FAR THE COLD FRONT COMES
DOWN. COULD END UP WITH OUTFLOW FROM KS CONVECTION OR IT COULD HELP
DRIVE THE FRONT ON DOWN. MY BEST GUESS SUPPORTED BY 99F AD ETA WILL
PUT A BOUNDARY...OUTFLOW OR COLD FRONT...FROM DHT TO GAG BY 12Z...
IT MAY DRIFT A LITTLE SOUTH OR JUST STALL OUT. THIS BOUNDRY AND
BETTER DEVELOPED DRYLINE WILL HELP WITH WED PM 5OOMB WAVE MOVING
ACROSS THE NW CWA. SO I ACTUALLY LIKE PRECIP CHANCES BETTER WED
EVEVING.
WILL KEEP CURRENT TREND FOR NORTH ZONES TONIGHT...BUT LOWER POPS IN
THE SOUTH. REST OF PACKAGE SEEMS OK AND WILL KEEP CLIMO TREND INTO
EXTENDED.
AMA...64/84 60/82 123
DHT...60/85 58/84 324

TX...NONE.
OK...NONE.
