.DISCUSSION...
/ISSUED 909 PM CDT SAT APR 30 2016/
A WAKE LOW HAS GENERATED WHAT APPEARS TO BE ONE OR MORE BORES ON
RADAR THAT ARE LIFTING N AND NE THRU NRN AL AS SEEN ON KHTX. I AM
UNSURE, BUT THE NORTHERN PERIPHERY OF THIS FEATURE MAY HAVE HELPED TO
KICK OF NEW SHRA/TSRA IN MIDDLE/SWRN TN. THERE HAS BEEN NO WINDS AT
THE SFC IN OUR FORECAST AREA, ALTHOUGH WIND GUSTS OF ~25KT ARE BEING
REPORTED IN THE BIRMINGHAM AREA. THE SHORT RANGE MODELS CONTINUE TO
VARY IN THEIR DEPICTION OF SOME REDEVELOPMENT OF CONVECTION TONIGHT.
THE 00Z SOUNDINGS REMAIN UNSTABLE ALOFT. THERE IS JUST A LACK OF A
DEFINED FORCING MECHANISM. 850 MB WINDS ALSO ARE PROGGED TO VEER TO
THE SW AND DECREASE OVERNIGHT, LIMITING MOISTURE TRANSPORT. SO HAVE
OPTED TO LOWER POPS FROM LIKELY TO CHANCE OVERNIGHT.

&&

.AVIATION...
FOR 06Z TAFS...UNCERTAINTY CONTINUES ON THE COVERAGE AND TIMING OF
SHOWERS AND THUNDERSTORMS THROUGH THE TAF PERIOD. BEST FORECAST AT
THIS TIME IS SCATTERED THUNDERSTORMS IN THE MORNING AROUND 10-13Z AND
THEN ANOTHER ROUND AS A COLD FRONT MOVES THROUGH AFTER 23Z-00Z BUT
THESE TIMINGS WILL LIKELY NEED TO BE UPDATED. SHOULD SEE SOME LOWER
CIGS/LOWER VIS DEVELOP IN THE NEXT FEW HOURS AND HAVE HANDLED WITH
TEMPO GROUPS WITH THE LOWEST VIS EXPECTED AT KMSL DUE TO THE RAIN
EARLIER. THE QUESTION THEN TURNS TO WHETHER OR NOT THE LOW CIGS WILL
SCATTER OUT TOMORROW AFTERNOON AND LOOKING AT PREVIOUS DAYS...WILL
GO AHEAD AND SCATTER IT OUT FOR A FEW HOURS BEFORE BRINGING BKN035
BACK IN WITH THE COLD FRONT.
