NATIONAL WEATHER SERVICE ST LOUIS MO
232 AM CDT TUE APR 10 2012

.SHORT TERM...
ISSUED AT 231 AM CDT TUE APR 10 2012
(TODAY AND TONIGHT)

WILL GO AHEAD AND UPGRADE CURRENT FREEZE WATCH TO A FREEZE WARNING
FOR ALL BUT ST. LOUIS CITY TONIGHT. HIGH TEMPERATURES ON MONDAY
CLIMBED INTO THE UPPER 60S AND LOWER 70S ACROSS THE CWA. THOSE
VALUES WILL NOT CLIMB AS HIGH TODAY AND NORTHERLY SURFACE WINDS
WILL CAUSE SLIGHT COLD AIR ADVECTION INTO EARLY AFTERNOON.
FORECAST SOUNDINGS FROM THE GFS/LOCAL WRF FAVOR MIXING TO 850MB
WHICH FAVORS A COMPROMISE OF THE GFS/NAM MOS HIGHS...WHICH WILL BE
ABOUT 10 DEGREES COOLER THAN YESTERDAY. THIS GIVES A COOLER
STARTING POINT FOR TEMPERATURES TO DROP FROM THIS EVENING. EXPECT
MAINLY CLEAR SKIES TONIGHT WITH LITTLE SHIFT IN THE AXIS OF THE
SURFACE RIDGE...SO THIS SUPPORTS TEMPERATURES FALLING INTO THE
29-32F RANGE ACROSS MOST OF THE CWA. THIS WILL POSE A RISK TO
VEGETATION THAT GOT A VERY EARLY START TO THE GROWING SEASON.
STILL HAVE KEPT ONLY PATCHY FROST FOR TONIGHT AS FORECAST
SOUNDINGS DO SHOW SOME SLIGHT MIXING AND DEWPOINT DEPRESSIONS
STILL LOOK LIKE THEY WILL BE ON THE ORDER OF 10 DEGREES. OTHERWISE
DRY WEATHER IS EXPECTED THROUGH TONIGHT AS WE REMAIN IN DRY
NORTHWESTERLY FLOW ALOFT.

.LONG TERM...
ISSUED AT 231 AM CDT TUE APR 10 2012
(TOMORROW THROUGH EARLY NEXT WEEK)

QUIET WEATHER IS EXPECTED FROM WEDNESDAY THROUGH THE FIRST HALF OF
THURSDAY GIVEN NW FLOW ALOFT AND A SFC HIGH PRESSURE CENTER SLIDING
SEWD TOWARD THE GRTLKS. WITH THE RIDGE AXIS OVERHEAD...CLR SKIES AND
LIGHT WINDS WILL SUPPORT GOOD RADIATIONAL COOLING CONDITIONS ON
WEDNESDAY NIGHT. SOME PATCHY FROST IS ALSO POSSIBLE LATE WEDNESDAY
NIGHT AND EARLY THURSDAY MORNING. THE HIGH AMPLITUDE RIDGE OVER THE
CENTRAL PART OF THE COUNTRY THEN SHIFTS SLOWLY EWD LATER THIS WEEK
AS A DEEP TROUGH DVLPS OVER THE WRN CONUS. THIS PATTN SHIFT WILL
BRING SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS TO OUR AREA FROM
THURSDAY AFTN/EVENING THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK
AS SEVERAL SHORTWAVES MOVE ACROSS THE REGION.

.AVIATION...

OTHERWISE...VFR CONDITIONS THROUGH THE FORECAST PERIOD...WITH JUST
