AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
325 PM CDT TUE JUN 17 2003

.UPDATE...
COORD WITH OHX...PONDERING FLOOD WATCH FOR THIS EVENING...AGREE WITH
FFC AND OHX THAT THE BEST COURSE OF ACTION IS TO HOLD OFF FOR NOW
AND LET THE NEXT TWO SHIFTS MONITOR. IF I WAS CERTAIN ABOUT RAINFALL
DEVELOPMENT OVERNIGHT...I WOULD BE ISSUING A FLOOD WATCH. FOR
NOW...WILL MENTION LOCALLY HEAVY RAINFALL IN ZONES TNGT AND WED.

.ORIGINAL DISCUSSION...
SLOWLY STARTING TO BECOME A BUSY AFTERNOON HERE AT THE HUN. SHOWERS
AND THUNDERSTORMS HAVE RAPIDLY FIRED ACROSS THE ENTIRE CWA. OUR
FLASH FLOOD MONITORING TOOL INDICATES TWO INCHES OF RAIN FELL JUST
SOUTH OF TUSCUMBIA BETWEEN 130 PM AND 200 PM THIS AFTERNOON...SO
NEEDLESS TO SAY THESE ARE PRECIPITATION-EFFICIENT STORMS TODAY. IF
PRECIP COVERAGE HOLDS ON TO ZONE ISSUANCE TIME...WILL NEED TO
MENTION HEAVY RAIN IN ZONES.

LOOKING AT KHTX RADAR...ALTHOUGH OUR PRECIPITATION IS NOT MOVING
ONLY SLOWLY...RAINFALL TO THE SOUTH IS MOVING NORTHWARD. THIS IS IN
ASSOCIATION WITH A SHORTWAVE...WHICH WILL ROTATE NORTHWARD TONIGHT.
ENERGY FROM THE MID-LEVEL LOW TO OUR WEST WILL KEEP MOVING THIS WAY
THROUGH THURSDAY...AND WILL NEED TO BOOST POPS AS A RESULT.

.SHORT TERM...
WITH CONTINUED MID/UPPER LEVEL ENERGY COMING ACROSS...AND BOUNDARIES
FROM THE CONVECTION ONGOING...WE EXPECT CONTINUED LIKELY RAIN
CHANCES TONIGHT AND TOMORROW. RAIN CHANCES WILL PROBABLY HOLD ON
WEDNESDAY NIGHT AND THURSDAY AS THE NEXT FRONT APPROACHES...AND WILL
BRING UP TO HIGH CHANCE-LEVEL POPS THERE. I ALSO WILL SIGNIFICANTLY
LOWER TOMORROWS MAX FORECAST TEMPS...CANT SEE US GETTING ANY
WARMER TOMORROW THAN WE HAVE TODAY.

.EXTENDED...
THE EXTENDED PROG HAS CHANGED QUITE A BIT FROM YESTERDAY. NOW A HIGH
PRESSURE SLIDES OFF TO OUR NORTH ON FRIDAY AND SATURDAY...AND
POTENTIALLY DRAGS THE NEXT FRONT THROUGH OUR AREA. IM WILLING TO
BUY INTO THIS AT THIS POINT...AS THERE IS DECENT MODEL CONSENSUS.
BUT IM NOT SURE HOW LONG THE DRIER CONDITIONS WILL LAST. AT THIS
POINT WILL JUST TREND DRIER FOR FRIDAY AND SATURDAY. EVENTUALLY AS
THE HIGH SLIDES OFF TO THE EAST...WE WILL INEVITABLY GET RETURN FLOW
AND COME BACK TO THE OLD STANDARD SUMMERTIME PATTERN AGAIN. AND I AM
HESITANT TO DRY OUT A SET OF DAYS ONLY TO HAVE TO FLIP-FLOP BACK TO
THE ORIGINAL SOLUTION LATER.
