Area forecast discussion, May 4, 4:00 AM CDT, 2 hours 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
400 AM CDT TUE MAY 4 1999

MAIN QUESTION IS WHETHER OR NOT JET MAX PUSHING OUT INTO PLAINS THIS
MORNING WILL SET OFF ANOTHER ROUND OF THUNDERSTORMS.  DEWPOINTS IN
THE 60S COVER ALL OF CENTRAL ZONES WITH VEERED WINDS AND SOMEWHAT
DRIER AIR OVER WESTERN ZONES. DONT CONSIDER THIS A TRUE DRYLINE BUT
THERE IS A CONVERGENT ZONE SET UP FROM ABOUT ALVA TO LAWTON.  LATEST
IR SAT SHOWS THICKENING MID CLOUDS WESTERN AND CENTRAL ZONES WHICH
SUPPORTS JET COMING OUT AND POTENTIAL FOR PRECIP DEVELOPMENT THIS
MORNING.

WILL PUT LOW POPS FOR THIS MORNING IN WEST WITH INCREASING POPS
CENTRAL AND EAST.  WILL MENTION SEVERE FOR ALL BUT WEST ZONES WHERE
SLIGHTLY DRIER AIR EXISTS AND WITH DRYLINE PASSAGE EARLY IN THE DAY.
ETA SHOWS 1000-2000 J/KG BY AFTERNOON CENTRAL AND EAST WHICH SEEMS
REASONABLE CONSIDERING CURRENT DEWPOINTS. SURFACE LOW PUSHING EAST
AND APPROACHING PACIFIC FRONT WILL MOVE DRYLINE EAST BY AFTERNOON.
CENTRAL AND EAST ZONES STILL UNDER THE GUN FOR SEVERE...ESPECIALLY
THIS AFTERNOON.

WILL KEEP LOW POPS FAR EAST THIS EVENING OTHERWISE DRY TONIGHT.
LITTLE CHANGES MADE FOR DAYS 2-5.  SURFACE HIGH PUSHES IN FROM THE
NORTHWEST.  UPPER LOW MOVES NORTHEAST THEN ANOTHER LOBE ROTATES
AROUND WED NIGHT-THU. WILL NOT MENTION PRECIP WITH THIS FEATURE AT
THIS TIME AND COUNT ON MOSTLY MID AND HIGH CLOUDS WITH DRIER SURFACE
RIDGE BENEATH.
