Area forecast discussion, Jun 22, 3:20 PM CDT, 1 hour 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
320 PM CDT WED JUN 22 2011

.DISCUSSION...

A DEEP OCCLUDED LOW PRESSURE SYSTEM IS NEARING THE GREAT LAKES
REGION...WITH THE TROUGH APPROACHING THE SOUTHEAST. LARGE-SCALE
SYNOPTIC LIFT IS GENERATING SCATTERED TO NUMEROUS SHOWERS/TSTMS
ACROSS GULF COAST STATES. PW VALUES ARE SLOWLY INCREASING...WITH
GREATER THAN 2 INCHES ACROSS THE WEST. CAPE AND SHEAR VALUES ARE
SUFFICIENT ENOUGH FOR ISO SEVERE STORMS ACROSS MUCH OF THE AREA. SPC
HAS PLACED THE MAJORITY OF THE CWA IN A SLIGHT RISK...AND A SEVERE
TSTM WATCH HAS BEEN ISSUED FOR THE NWRN 2 THIRDS OF THE CWA. JUST
LIKE YESTERDAY THE MAIN THREAT WILL BE DAMAGING STRAIGHT-LINE WINDS.
TSTM ACTIVITY WILL CONTINUE INTO THE OVERNIGHT PERIOD...BUT THE
INTENSITY AND COVERAGE IS EXPECTED TO DECREASE AFTER SUNSET.

THE BEST RAIN CHANCES WILL SHIFT TO THE SOUTHEAST ON THUR AS THE
UPPER LEVEL TROUGH PUSHES ACROSS THE FORECAST AREA. SLIGHTLY DRIER
AIR WILL WORK IN BEHIND THE TROUGH BY THU EVNG...KEEPING POPS LOW
FOR THUR NIGHT. NW FLOW ALOFT WILL SET UP ACROSS CENTRAL ALABAMA ON
FRI AS THE TROUGH PUSHES OFF TO OUR EAST AND THE UPPER RIDGE OVER
TEXAS BEGINS TO BUILD EWD. MODELS BRING SEVERAL SHORTWAVES ACROSS
THE AREA FROM FRI THRU THE WEEKEND. MOISTURE WILL NOT BE AN ISSUE AS
PW VALUES WILL REMAIN IN THE 1.75 TO 2 IN RANGE THRU MUCH OF THE
PERIOD. SCT TSTMS WILL BE POSSIBLE EACH AFTN DURING PEAK HEATING
HRS. WILL GENERALLY KEEP CHANCE POPS IN FOR THE DAYTIME PERIODS
DECREASING TO SLIGHT CHANCE EACH NIGHT. ANY MCS DEVELOPMENT COULD
LEAD TO SIGNIFICANT INCREASES IN RAIN CHANCES.

TEMPS WILL REMAIN NEAR NORMAL THRU THE WEEKEND...WITH HIGHS IN THE
UPPER 80S TO LOW 90S AND OVERNIGHT LOWS IN THE UPPER 60S TO LOW 70S.
TEMPS WILL BEGIN TO MODERATE NEXT WEEK AS THE UPPER RIDGE BUILDS
CLOSER TO THE AREA AND PUSHES MOST OF THE ORGANIZED TSTM ACTIVITY TO OUR
EAST.

19

&&

.AVIATION...18Z TAF DISCUSSION.

NUMEROUS AREAS OF CONVECTION TODAY ACROSS CENTRAL ALABAMA. THIS WILL
BE ON AND OFF IN SEVERAL WAVES...BUT WILL AT TIMES KEEP CIGS DOWN
BELOW 3 KFT. VISIBILITIES SHOULD BE FINE OUTSIDE OF TSRA. TIMING OF
STORMS WILL BE TOUGHEST PART TODAY SINCE THERE WILL BE MULTIPLE
OCCURRENCES AS UPPER DISTURBANCES MOVES NORTHEAST ACROSS THE STATE.
THURSDAY WILL HAVE SCATTERED TSRA POSSIBLE BUT NOT AS WIDESPREAD AS
TODAY. LEAVING OUT MENTION OF THU ACTIVITY AS TOO HARD TO PINPOINT
AT THIS TIME.

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.
