240 AM CST FRI FEB 21 2003

NOTHING TO GET EXCITED ABOUT IN THE SHORT TERM. MAJOR SYSTEM IN
THE SOUTHERN STREAM WILL COMPLETELY MISS THE CWFA. ARCTIC FRONT TO
SLOWLY OOZE TOWARD CWFA DURING THE DAY WITH FORECAST SOUNDINGS
INDICATING NOTHING MORE THAT CI/CS AND POSSIBLY SOME AC.
UKMET/ETA12 VERY SIMILAR IN MOVEMENT OF ARCTIC FRONT THROUGH TONIGHT
WITH LOW CLOUDS ARRIVING. QG FORCING DIMINISHES WITH TIME AS DOES
SURFACE CONVERGENCE. DOUBTFUL BUT WOULD NOT BE TOTALLY SURPRISED TO
SEE A FEW --SN. PRESSURE GRADIENT INCREASES SATURDAY AS SOUTHERN
SYSTEM WINDS UP. THAT AND CONTINUED OOZING OF COLD AIR IN MIGHT BE
ENOUGH FOR SOME --SN ON SATURDAY. QUIET WX SATURDAY NIGHT/SUNDAY
MORNING BEFORE SECOND SYSTEM COMES THROUGH. BETTER FORCING/LIFT
WITH THIS AND MAY ALLOW SOME -SN TO OCCUR BUT AVAILABLE MOISTURE IS
IN QUESTION. TREND THIS WINTER HAS BEEN GOING TOO HIGH WITH
AMOUNTS...SO BEST GUESS ATTM WOULD BE AN INCH (IF THAT) AND
ALLOWING FOR HIGH SNOW/RAIN RATIOS.

TEMPS TO START OUT WARMER TODAY THAN YESTERDAY. EVEN WITH CLOUDS...
MAX TEMPS SHOULD BE SIMILAR TO YESTERDAY. DIURNAL CHANGE FOR
SATURDAY AND SUNDAY SHOULD BE FAIRLY SMALL WITH CAA AND LOW CLOUDS.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
