Severe Thunderstorm Warning 275, NWS Birmingham, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1215 PM CDT SAT JUN 11 2011

.UPDATE...FOR 18Z AVIATION.

&&

.DISCUSSION...

IF YOU TAKE A LOOK AT MORNING SATELLITE IMAGES...SAY AROUND
12Z...YOU CAN BEGIN TO DISCERN THE IDEA OF A WEAK SYNOPTIC BOUNDARY
THAT HAS MOVED INTO THE NORTHERN HALF OF THE STATE.  THIS BOUNDARY
WILL LIKELY HELP TO FOCUS THUNDERSTORM DEVELOPMENT THIS AFTERNOON.
CURRENT FORECAST HAS CHANCE POPS ACROSS ALONG THE I-20/59
CORRIDOR...AND I CONTINUE TO LIKE THIS IDEA FOR THE AFTERNOON.  CU
FIELDS SHOULD BEGIN TO POP ACROSS ALABAMA AFTER 11 AM...AND IF WE
HAVE ANYTHING LIKE WE HAD YESTERDAY...STORMS SHOULD BEGIN TO DEVELOP
BY 12 PM.  THIS MORNING'S SOUNDING IS VERY SIMILAR TO YESTERDAY...
SO EVEN THOUGH THE MICROBURST POTENTIAL IS LOW...THERE WILL BE A
SHOT AT HAIL AGAIN TODAY.  THAT SAID...EVEN WITH THE CHANCE OF THE
HAIL...THE ISOLATED TO SCATTERED NATURE OF THE STORMS WILL PRECLUDE
ANYTHING BEING ADDED TO THE HAZARDOUS WEATHER OUTLOOK.

UPDATE OUT SHORTLY.

27

&&

.AVIATION...18Z TAF DISCUSSION.

MOSTLY VFR CONDITIONS THIS AFTERNOON...BUT WILL HAVE TO DEAL WITH
ISOLATED TO SCATTERED SH/TS WHICH WILL HANDLE WITH AMD THROUGH 02Z.
BEYOND 02Z...PROBABLY WILL SEE AT LEAST MVFR VIS NEAR SUNRISE AT
JUST ABOUT EVERY SITE...WITH KANB POTENTIALLY FALLING TO IFR FOR A
COUPLE OF HOURS.

WINDS WILL BASICALLY BE LIGHT OUT OF THE NORTH...OTHER THAN IF YOU
GET AROUND ONE OF THE AFTERNOON THUNDERSTORMS...WHICH COULD GIVE A
GUST TO 25 KTS...AND SOME HAIL.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST UNTIL FURTHER NOTICE. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.

27

&&

.CLIMATE...

THROUGH THE FIRST 9 DAYS OF JUNE...THE BIG CITY CLIMATE LOCATIONS
(BHM...TCL...ANB...AND MGM) HAVE ALL EXPERIENCED EITHER THE
WARMEST OR SECOND WARMEST START TO THE MONTH IN THEIR RESPECTIVE
PERIODS OF RECORD. THIS JUNE HEAT WAVE...AT LEAST SO FAR...HAS
RIVALED OR EXCEEDED THE JUNE 1985 HEAT WAVE.

&&

.BMX WATCHES/WARNINGS/ADVISORIES...NONE.
