Flash Flood Warning 18, NWS Birmingham, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
457 AM CST FRI APR 1 2005

.SHORT TERM...(TODAY THROUGH MONDAY)

ONE MORE DAY OF MESSY WEATHER BEFORE WE CAN ENJOY A DRY NICE
WEEKEND WITH COOLER TEMPERATURES. FOR NOW...WE HAVE TO DEAL WITH
THESE SHOWERS AND THUNDERSTORMS THROUGH MOST OF THE DAY TODAY. THE
GOOD NEWS IS THAT WE SEEM TO BE CUT OFF FROM THE UNSTABLE
AIRMASS...SO I DO NOT EXPECT ANY SEVERE STORMS TO DEVELOP OVER OUR
FORECAST AREA. THE BAD NEWS THOUGH IS THAT WE HAVE TO DEAL WITH
FLOODING. SOME OF THESE STORMS WILL PRODUCE PERIODS OF VERY HEAVY
RAIN IN A SHORT AMOUNT OF TIME. ALSO...WE COULD HAVE SOME TRAINING
EFFECTS THAT COULD MAKE MATTERS WORST. A FLOOD WATCH IS OUT FOR
MOST OF THE CWA UNTIL THIS AFTERNOON. ANOTHER PROBLEM IS THAT MOST
OF THE RIVERS UNDER OUR FORECAST AREA ARE EITHER FLOODING OR CLOSE
TO FLOOD. WE WILL MONITOR THESE RIVERS AND WILL ISSUE ADDITIONAL
FLOOD WARNINGS ACCORDINGLY. PEOPLE LIVING AT OR NEAR LOW LYING AREAS...
CREEKS...RIVERS...AND FLOOD PRONE AREAS SHOULD CLOSELY MONITOR THE
WEATHER FOR ANY POTENTIAL FLOOD WARNINGS ISSUED FOR YOUR COUNTY.
BE PREPARED TO TAKE ACTION...AND PLEASE...DO NOT DRIVE ACROSS
FLOODED AREAS. TURN AROUND DONT DROWN...

NOW...BACK TO THE FORECAST. MOST OF THE RAIN WILL BEGIN TO MOVE
OUT OF OUR AREA TONIGHT. AS THE LOW PRESSURE SYSTEMS MOVES OUT OF
OUR CWA...A TIGHT PRESSURE GRADIENT WILL DEVELOP OVER CENTRAL
ALABAMA. THIS WILL LEAD TO SOME GUSTY WINDS STARTING TONIGHT AND
CONTINUE THROUGH SATURDAY. THE WIND WILL BE STRONGER ON SATURDAY
DUE TO A COMBINATION OF THE TIGHT PRESSURE GRADIENT AND A LOW LEVEL
JET...WHICH SOME OF THE WINDS WILL MIX DOWN TO THE SURFACE. A LAKE
WILL ADVISORY WILL PROBABLY HAVE TO BE ISSUED...ALTHOUGH WE MAY
ACTUALLY REACH WIND ADVISORY CRITERIA. BY THIS EVENING...WE SHOULD
HAVE A BETTER IDEA ON WHICH CRITERIA WILL BE MET.

BESIDES THE STRONG WINDS ON SATURDAY...THE WEEKEND OVERALL LOOKS
REALLY GOOD. TEMPERATURES WILL COOL OFF INTO THE UPPER 30S AND
LOWER 40S DURING THE EVENING...AND WARM UP TO THE UPPER 50S TO MID
60S. SATURDAY LOOKS TO BE THE COOLER DAY DUE TO THE WINDS MAKING
THE TEMPERATURES FEEL MUCH COOLER. BY LATE SATURDAY...WINDS SHOULD
BEGIN TO DIE DOWN AND BY SUNDAY WILL BECOME CALM.  DRY CONDITIONS WILL
CONTINUE THROUGH EARLY NEXT WEEK...BUT TEMPERATURES WILL BEGIN TO
WARM UP.

.LONG TERM...(TUESDAY THROUGH THURSDAY)

THE NEXT WEATHER SYSTEM WILL APPROACH THE AREA ON WEDNESDAY.
SHOWERS AND THUNDERSTORMS ARE EXPECTED...BUT OF COURSE WITH EVERY
SYSTEM THAT MOVES THROUGH THIS TIME OF THE YEAR...SEVERE WEATHER
COULD ALWAYS BE A POSSIBILITY. AS OF RIGHT NOW...IT DOESNT LOOK
TOO PROMISING...BUT IT IS TOO EARLY TO TELL.
