AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1030 AM CDT THU OCT 26 2000

SHORT WAVE CURRENTLY MOVING ACROSS OKLAHOMA AND NORTH TEXAS WILL
MOVE SLOWLY EAST AND GRADUALLY WEAKEN. FAIRLY DECENT AREA OF
CONVECTION EXPECTED TO SPREAD EAST TONIGHT AND BRING RAIN TO THE
CWA...ESPECIALLY NORTHERN MOST ZONES. MOISTURE IS PLENTIFUL WITH THIS
SYSTEM...SO SOME DECENT AMOUNTS EXPECTED IN THE NORTH. RAINFALL
SOUTH OF I20 AND EAST OF I49 WILL BE MORE SCATTERED. NGM AND ETA
CARRY THE RAINFALL FURTHER SOUTH...WHILE THE AVN HOLDS IT MORE IN
OKLAHOMA. BASED ON DEVELOPMENT IN NORTHCENTRAL TEXAS THIS AFTERNOON
HAVE DECIDED TO GO WITH THE ETA/NGM. ALL MODELS SHIFT MOISTURE TO
THE NORTH BY SATURDAY...SO WILL DROP MENTION ALL BUT MOST NORTHERN
ZONES.

NEXT SYSTEM LOOKS PROMISING FOR MORE RAINFALL IN THE EXTENDED...SO
WILL CONTINUE WITH THE RAIN IN THE FORECAST SUNDAY BASED ON
CONTINUITY WITH THE MESO ETA. MRF SEEMS TOO FAST WITH THESE DEEP
TROFS...SO A THIRD SYSTEM BY TUESDAY LOOKS TOO FAST.

DEWPOINTS ARE UP WELL INTO THE 60S THIS AFTERNOON...SO FIRST PERIOD
AVN/NGM MOS TEMPS LOOK A LITTLE ON THE LOW SIDE. BEYOND THAT...
GUIDANCE NUMBERS LOOK REASONABLE.

PRELIMS...
