Area forecast discussion, Jul 23, 2:08 PM CDT, 2 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
208 PM CDT THU JUL 23 2015

.DISCUSSION...

NUMEROUS TO WIDESPREAD CONVECTION ONGOING ACROSS CENTRAL ALABAMA
THANKS TO SOME UPPER LEVEL IMPULSES MOVING EAST ACROSS THE REGION.
SOUNDINGS SHOW FAIRLY SATURATED PROFILES WHICH IS EVIDENCED BY THE
RAINFALL EFFICIENCY OF THE STORMS. ALTHOUGH AN ISOLATED DAMAGING
WIND GUST CAN'T BE RULED OUT THE SEVERE THREAT SHOULD BE MUCH
LESS TODAY AS COMPARED TO YESTERDAY. WIND GUSTS OF 40-60 MPH WILL
REMAIN POSSIBLE WITH THE STRONGER STORMS...AS WELL AS HEAVY
RAINFALL AND FREQUENT CG LIGHTNING. SOME LOCALIZED MINOR FLOODING
IS POSSIBLE IN POOR DRAINAGE AREAS. SOME CONVECTION WILL LIKELY
LINGER THROUGH THE EVENING AND POTENTIALLY INTO THE OVERNIGHT
PERIOD AS YET ANOTHER IMPULSE COULD TRAVERSE THE AREA.

TROUGHING DEVELOPS ALONG THE ATLANTIC COAST ON FRIDAY AND PUSHES
THE RIDGE A BIT TO THE WEST. RAIN CHANCES WILL BEGIN TO DECREASE
BUT SCATTERED SHOWERS/STORMS WILL REMAIN POSSIBLE. SOME STRONG
STORMS WILL STILL BE A POSSIBILITY ON FRIDAY WITH THE MAIN THREAT
ONCE AGAIN STRONG WIND GUSTS. ALTHOUGH IT WILL HOT AND HUMID NO
HEAT ADVISORIES ARE CURRENTLY IN EFFECT. TEMPS WILL BE IN THE LOW/MID 90S IN
MOST LOCATIONS BUT HEAT INDICES SHOULD REMAIN BELOW 105 DEGREES.

DRIER CONDITIONS ARE IN STORE OVER THE WEEKEND AND INTO MONDAY.
SFC RIDGING WILL DEVELOP ALONG THE APPALACHIAN MOUNTAINS AND
WILL FINALLY PUSH THE QUASISTATIONARY FRONT...THAT'S BEEN HANGING
AROUND TO OUR NORTH...TO OUR SOUTHWEST. TEMPS WILL STILL RISE INTO
THE LOW/MID 90S BUT THE DRIER AIR WILL HELP KEEP HEAT INDICES
BELOW CRITICAL LEVELS. RAIN CHANCES WILL GRADUALLY INCREASE BACK
TO CLIMATOLOGICAL NORMS BY MID WEEK.

19

&&

.AVIATION...
18Z TAF DISCUSSION.

LINE OF STORMS FROM TCL TO ANB WILL CONTINUE TO DRIFT SOUTHWARD.
MAIN CONCERN OVER THE NEXT 2 HOURS WILL BE TCL...EET...ANB...AND
ASN FOR WINDS OF 25 TO 30KTS AND LIGHTNING. TOI IS CURRENTLY
SEEING A THUNDERSTORM WORK JUST TO THE SOUTH OF THE AREA BUT CLOSE
ENOUGH TO INCLUDE A THUNDERSTORM AT THIS TIME. MGM WILL SEE SOME
INCREASE IN ACTIVITY AFTER 19Z. RAIN MAY REMAIN IN THE AREA BUT BE
MORE OF THE SHOWER VARIETY AFTER 6Z AND 9Z SOUTH. WILL NEED TO
MONITOR UNTIL THEN FOR ANY ADDITIONAL THUNDERSTORMS AS ANOTHER
DISTURBANCE WILL TRY TO SLIDE THROUGH. AFTER 15 THE MAJORITY OF
TAF SITES WILL IMPROVE WITH HIGHEST CHANCES AT SEEING ANY
PRECIPITATION AT TCL. AMENDMENT ARE LIKELY AS THE STORMS SLIDE
THROUGH THE AFTERNOON AND EVENING.

16

&&

.FIRE WEATHER...

NUMEROUS TO WIDESPREAD SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO
THE EVENING HOURS. DRIER CONDITIONS ARE EXPECTED SATURDAY THROUGH
TUESDAY. MEAN LAYER WINDS ARE NOT TOO HIGH WHICH LEADS TO SOMEWHAT
LOWER DISPERSION VALUES.
