PROGRESSIVE LOW AMPLITUDE PATTERN WILL PREVAIL THROUGH TUESDAY.
UPPER TROUGH OFF THE PACIFIC NW COAST IS FORECAST TO EJECT EWD
THROUGH THE NRN ROCKIES TUESDAY...REACHING THE NRN PLAINS AND UPPER
MS VALLEY BY THE END OF THE PERIOD.

...NRN ROCKIES...

STEEPER MID LEVEL LAPSE RATES AND ASCENT ATTENDING THE SHORTWAVE
TROUGH EXPECTED TO MOVE THROUGH THE PACIFIC NW AND NRN ROCKIES MAY
CONTRIBUTE TO DEVELOPMENT OF ISOLATED CONVECTION OVER PARTS OF THE
NRN ROCKIES DURING THE AFTERNOON. HOWEVER...COVERAGE WILL LIKELY
REMAIN AOB 10% DUE TO LIMITED INSTABILITY.

...SRN PLAINS AND LOWER MS VALLEY...

LOW-LEVEL TRAJECTORIES EMANATING FROM A LARGE AREA OF HIGH PRESSURE

OVER THE GULF. AN AXIS OF MODIFIED CP AIR WILL BEGIN RETURNING NWD

PROBABLE SINCE THE SYSTEM IS APPARENTLY AT PEAK INTENSITY

HOURS -- DECREASING FROM S-N WITH TIME...BUT STILL ACCOMPANIED BY
OCCASIONAL/LOCALIZED BLIZZARD CONDITIONS. OVERALL ORGANIZATION OF

0403 AM CST MON FEB 23 2009

VALID 261200Z - 031200Z

THE MEDIUM RANGE MODELS BEGIN THE DAY 4 TO 8 PERIOD WITH A ZONAL
FLOW PATTERN IN PLACE. A VERY SUBTLE UPPER-LEVEL TROUGH IS FORECAST
TO MOVE EWD ACROSS THE MS VALLEY THURSDAY/DAY 4 AND ACROSS THE ERN
SEABOARD FRIDAY. IN RESPONSE TO THIS SYSTEM...A WELL-DEVELOPED
LOW-LEVEL JET IS FORECAST TO TRANSPORT MOISTURE NWD INTO THE OZARKS.
LARGE-SCALE ASCENT WITH THE UPPER-LEVEL TROUGH AND LIFT ASSOCIATED
WITH THE LOW-LEVEL JET SHOULD PROMOTE THUNDERSTORM DEVELOPMENT
ACROSS THE OZARKS AND POSSIBLY THE LOWER OH VALLEY DURING THE DAY ON
THURSDAY. THIS ACTIVITY SHOULD SHIFT EWD ACROSS THE OH VALLEY AND
MID-MS VALLEY THURSDAY NIGHT REACHING THE ERN SEABOARD AND GULF
COAST STATES ON FRIDAY. THE GREATEST POTENTIAL FOR ISOLATED SEVERE
STORMS APPEARS TO BE ON THURSDAY ACROSS THE OZARKS WHERE SFC
DEWPOINTS COULD BE IN THE 50S F. HOWEVER...DUE TO WEAK
INSTABILITY...THE THREAT DOES NOT WARRANT AN OUTLOOK AREA ATTM.

BEYOND FRIDAY/DAY 5...MODEL FORECASTS ARE IN GENERAL AGREEMENT
BRINGING AN UPPER-LEVEL TROUGH INTO THE CNTRL U.S. SATURDAY/DAY 6.
AHEAD OF THIS TROUGH...MOISTURE AND INSTABILITY SHOULD RETURN NWD
INTO THE GULF COAST STATES. THIS COMBINED WITH STRONG VERTICAL SHEAR
ASSOCIATED WITH A BROAD MID-LEVEL JET MAY PROMOTE SEVERE
THUNDERSTORM DEVELOPMENT SATURDAY AFTERNOON. HOWEVER...THE TIMING
AND AMPLITUDE OF THE UPPER-LEVEL TROUGH REMAINS HIGHLY QUESTIONABLE.
PREDICTABILITY APPEARS TO LOW FOR AN OUTLOOK AREA ATTM.

JET AND APPROACHING UPPER-LEVEL TROUGH MAY BE ENOUGH FOR ISOLATED
THUNDERSTORM DEVELOPMENT. HOWEVER...ORGANIZED CONVECTION IS NOT
EXPECTED DUE TO LIMITED INSTABILITY.

A POTENT NEG TILT S/W TROUGH MOVING NE ACROSS THE CAPE COD REGION AT

12-15Z/MON. STRONG UPPER LEVEL DIVERGENCE AND SYNOPTIC SCALE ASCENT
/EVIDENT BY HOURLY PRESSURE FALLS OF 5 MB OFF THE COAST OF ME/ WILL
ACCOMPANY THIS FEATURE...FAVORING DEEPLY SATURATED ENVIRONMENT OVER
