What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS St. Louis, MO wrote its last area forecast discussion before this river flood warning went out at Mar 12, 5:36 AM CDT, 4 hours 14 minutes earlier.

Area forecast discussion, Mar 12, 5:36 AM CDT, 4 hours 14 minutes before

AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
536 AM CDT THU MAR 12 2009

.DISCUSSION...
/428 AM CDT THU MAR 12 2009/
PRIMARY CONCERN FOR THIS FORECAST PACKAGE IS PRECIPITATION THREAT
FOR THE EXTREME SOUTHERN PORTION OF THE CWFA...BASICALLY
REYNOLDS...IRON...AND MADISON COUNTIES IN MISSOURI.  PREVIOUS
FORECAST HAD LIKELY POPS WITH A VERY SHARP GRADIENT OF ACCUMULATING
SNOW FROM A TRACE UP TO AROUND 2 INCHES IN THE EXTREME SOUTHERN TIP
OF REYNOLDS COUNTY.  IT NOW LOOKS LIKE DRY AIR INTRUSION FROM THE
STRONG HIGH PRESSURE SYSTEM CENTERED OVER MINNESOTA THIS MORNING
WILL PUT THE KIBOSH ON THE SNOW.  VERY DRY LOW LEVEL AIR CONTINUES
TO WRAP CLOCKWISE AROUND THE HIGH.  SURFACE DEWPOINTS ARE IN THE
TEENS AND 850MB DEWPOINT DEPRESSIONS ARE AS MUCH AS 25-30 DEGREES
OVER THE AREA. 925-850MB RH HAS REAL DIFFICULTY GETTING ABOVE 40
PERCENT THROUGH THE DAY ACCORDING TO BOTH THE GFS AND THE NAM.
ADDITIONALLY THE NMM CORE WRF AND OUR LOCAL WRF AGREE WITH THE
OPERATIONAL MODELS IN KEEPING PRECIP SOUTH OF THE AREA.  HAVE
THEREFORE REDUCED POPS DRASTICALLY ACROSS THE SOUTHERN SECTIONS OF
THE CWFA AND REMOVED ALL MENTION OF ACCUMULATION.

REMAINDER OF THE FORECAST IS BASICALLY UNCHANGED FROM PREVIOUS
PACKAGE.  HIGH PRESSURE IS STILL PROGGED TO BUILD EAST ACROSS THE
OHIO VALLEY THROUGH THE WEEKEND. THIS WILL EVENTUALLY ALLOW RETURN
FLOW TO DEVELOP OVER THE BI-STATE REGION BY SATURDAY.  GFS AND ECMWF
HAVE COME INTO SOMEWHAT BETTER AGREEMENT REGARDING PRECIPITATION
CHANCES FOR THE WEEKEND AS RETURN FLOW BRINGS MOISTURE BACK TO THE
AREA.  STILL LOOKS LIKE PRIMARILY A LITTLE LIGHT RAIN FOR SATURDAY
AND POSSIBLY SATURDAY NIGHT AS WARM ADVECTION AND SHORTWAVE ENERGY
INTERACT TO PRODUCE LIFT OVER THE AREA.  PRECIP COULD START AS A
LITTLE SNOW SATURDAY MORNING...BUT HAVE LEFT MENTION SNOW OUT FOR
NOW SINCE IT LOOKS LIKE ANY FLAKES WILL BE SHORT-LIVED AND HAVE
LITTLE OR NO IMPACT ON THE OVERALL FORECAST.  TEMPERATURES WILL
CONTINUE TO RUN BELOW NORMAL TODAY AND FRIDAY...BUT WILL BE
MODERATING TOWARD NORMAL VALUES BY SATURDAY AND CONTINUE NEAR NORMAL
THROUGH THE WEEKEND.
