305 PM EDT THU MAY 29 2003

TONIGHT AND FRIDAY...
SHORT WAVE ROTATING THRU SE KENTUCKY PRODUCING A FEW SCATTERED
SHOWERS ACROSS REGION WHICH SHOULD DIE OFF RAPIDLY ONCE THE SUN
SETS.  FRIDAY DAYTIME STILL LOOKS DRY AS HIGH PRESSURE ALONG GULF
COAST TRIES TO BRIEFLY RIDGE INTO AREA.

FRIDAY NIGHT THROUGH SUNDAY NIGHT...
ONLY MINOR TIMING DIFFERENCES IN THE RATHER STRONG FRONTAL SYSTEM
THAT PUSHES THROUGH LATE FRIDAY NIGHT OR EARLY SATURDAY MORNING. ALL
AGREE THAT THIS VIGOROUS SYSTEM HAS GOOD MOISTURE TO WORK WITH AND
MARGINAL INSTABILITY.  SHOWERS AND THUNDERSTORMS ASSOCIATED WITH
THIS FRONT ARE LIKELY FRIDAY NIGHT ESPECIALLY IN THE WEST...AND ON
SATURDAY MORNING ESPECIALLY IN THE EAST.  HIGH PRESSURE AND CLEARING
SKIES ARE EXPECTED BY SUNDAY AS CANADIAN HIGH PRESSURE BUILDS IN.
TEMPERATURES WILL CONTINUE TO AVERAGE BELOW NORMAL.

MONDAY THROUGH THURSDAY...
MODELS ARE BEGINNING TO SHOW A BIT OF A PATTERN SHIFT IN THE
EXTENDED RANGE...WITH THE RIDGE IN THE WEST MOVING TOWARD THE WEST
COAST AND MORE OF THE TROUGH DIGGING INTO THE INTERMOUNTAIN WEST BY
LATE NEXT WEEK.  THIS WILL ALLOW MORE RIDGING TO DEVELOP ACROSS THE
SOUTHEASTERN US...WHICH WILL HAVE A BIG IMPACT ON THE WEATHER FOR
WED AND THURS.

FIRST...HIGH PRESSURE WILL REMAIN IN CONTROL ON MONDAY.  MAY SEE AN
INCREASE IN CLOUDS LATER IN THE DAY...BUT OVER...MONDAY SHOULD BE A
NICE DRY DAY WITH TEMPERATURES WARMING ABOUT 5 TO 10 DEGREES FROM
SUNDAY HIGHS.  AS THE HIGH SLIDES SOUTHEAST ON MONDAY...THE WINDS
WILL GRADUALLY BECOME SOUTHWESTERLY...WHICH WILL HELP THE WARMUP.

TUESDAY WILL REMAIN DRY AS THE LAST IN A SERIES OF SYSTEMS IN THE
NORTHWEST FLOW ORGANIZES OVER THE NORTHERN PLAINS AND WESTERN GREAT
LAKE STATES.  THIS SYSTEM WILL APPROACH ON WEDNESDAY...BUT THE UPPER
LEVEL PATTERN CHANGE...THE FRONT WILL STRUGGLE TO MOVE ACROSS THE
OHIO VALLEY AND MAY BECOME STATIONARY.  THIS WILL CAUSE MORE CLOUDS
WITH SHOWERS AND TSTORMS POSSIBLE.  THIS THREAT WILL LINGER INTO
THURSDAY AS WELL.

FOR TEMPERATURES...MEX GUIDANCE WAS PRETTY CLOSE.  HAVE TONED DOWN
HIGH TEMPS FOR TUESDAY...WEDNESDAY AND THURSDAY...PER ENSEMBLE MOS
ALONG  WITH OPERATIONAL GFS BEING FASTER THAN HPC ANTICIPATED
POSITIONS OF THE FRONTAL BOUNDARIES.
