...FLASH FLOOD WARNING REMAINS IN EFFECT FOR NORTHERN MONTGOMERY
COUNTY UNTIL 730 PM CDT...

AT 527 PM CDT...HEAVY RAIN ESTIMATES ON RADAR OF NEAR 2 TO 3 INCHES 
HAS FALLEN OVER THE LAST HOUR OR SO OVER DOWNTOWN MONTGOMERY PROPER. 
THIS HAS CAUSED URBAN AREAS TO HAVE WATER ACROSS ROADWAYS DURING 
PEAK TRAFFIC TIMES AND FLASH FLOODING CONTINUES TO BE POSSIBLE. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

THIS IS A DANGEROUS SITUATION. RAINFALL FROM PERSISTENT RAINBANDS
WILL PRODUCE FLOODING IN LOW LYING AREAS AND ALONG STREETS. MANY
ROADS WILL BE CLOSED DUE TO HIGH WATER AND DRIVING IS NOT RECOMMENDED
DURING THE NEXT FEW HOURS.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
309 PM CDT TUE JUL 9 2013

.DISCUSSION...

FINALLY MUCH OF THE AREA HAS SEEN ABUNDANT SUNSHINE TODAY. SHOWER
AND THUNDERSTORM ACTIVITY HAS BEEN LIMITED BY SLIGHTLY DRIER AND
WARMER AIR ALOFT. THESE SHOWERS AND STORMS SHOULD BE DIURNALLY
DRIVEN AND DIMINISH IN COVERAGE THROUGH THE EVENING HOURS.

MODELS AGREE THAT WEAK HEIGHT FALLS SHOULD OCCUR ON WEDNESDAY AND
ALLOW FOR GREATER COVERAGE OF SHOWERS AND STORMS. THE BEST CHANCE
SHOULD BE ACROSS THE EAST WHERE A WEAKNESS IN THE MID-LEVEL RIDGE
IS EXPECTED TO DEVELOP.

A TROUGH SWINGING THROUGH THE NORTHEAST STATES WILL ALLOW A WEAK
COLD FRONT TO MOVE INTO THE REGION ON THURSDAY WITH WIDESPREAD
SHOWERS AND STORMS EXPECTED ALONG AND AHEAD OF THE FRONT. HIGH
PRESSURE AND NORTHERLY FLOW IN THE WAKE OF THE FRONT WILL LEAD TO
COOLER AND DRIER CONDITIONS FOR FRIDAY WITH ONLY MINIMAL RAIN
CHANCES ACROSS THE SOUTHERN FRINGE OF THE CWA. EASTERLY FLOW IS
EXPECTED TO DEVELOP BY SATURDAY AND SUNDAY AS PART OF THE UPPER
TROUGH BREAKS OFF AND MOVES WESTWARD AROUND THE PERIPHERY OF A
CENTRAL U.S. RIDGE. THIS SHOULD ALLOW FOR MOISTURE RETURN INTO OUR
REGION AND A MODEST INCREASE IN RAIN CHANCES BY SUNDAY AND MONDAY.

.AVIATION...
18Z TAF DISCUSSION.

THE EARLY MORNING IFR CIGS WERE SLOW TO LIFT AND BURN OFF...BUT
CIGS DURING THE EARLY PORTION OF THE FORECAST PERIOD WILL BE
MVFR...BECOMING VFR BY 20Z. THE AIR MASS IS VERY MOIST AND ISOLD
SHWRS HAVE ALREADY DEVELOPED ACROSS MOST OF CENTRAL ALABAMA. THE
SHWRS WILL LIKELY INCREASE IN COVERAGE DURING THE AFTN AND BECOME
MAINLY TSTMS BY 21Z. DECIDED TO ADD VCSH/VCTS TO FIRST SIX HOURS
OF TAF CYCLE TO ACCOUNT FOR DECENT COVERAGE OF CONVECTION. THE
CONVECTION SHOULD DISSIPATE QUICKLY AFTER 00Z. THERE IS A LOW
LEVEL HIGH OVER THE NORTHERN GULF OF MEXICO WITH CENTRAL ALABAMA
UNDER THE NORTHERN TIP OF THE SURFACE RIDGE AXIS...PRODUCING A
PREVAILING WESTERLY FLOW. HOWEVER...PRESSURE GRADIENT IS SO WEAK
THAT WINDS HAVE BEEN VRBL AND EXPECT THIS TREND TO CONTINUE. THERE
WILL LIKELY BE ANOTHER ROUND OF STRATUS WEDNESDAY MORNING...BUT IT
IS DIFFICULT TO PINPOINT WHICH AREAS WILL EXPERIENCE IFR CIGS..AND
JUST INCLUDED LOW CIGS FOR ALL TAF SITES TOWARDS THE END OF THE
TAF CYCLE.
