AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
1052 AM CDT WED MAY 4 2016

.UPDATE...
MORNING UPDATE. ADJUSTED POP/WX FOR THIS AFTERNOON.

&&

.DISCUSSION...
THIS MORNING STARTED OFF A BIT COOLER WITH OVERNIGHT LOWS IN THE 40S
AND MOSTLY CLEAR SKIES. CLOUD COVER HOWEVER WILL INCREASE THROUGHOUT
THE DAY DUE TO AN INVERTED TROUGH ACROSS THE REGION AND AN COLD FRONT
APPROACHING FROM THE NORTHWEST. TODAYS HIGH TEMPS WILL STRIVE TO
REACH BELOW NORMAL VALUES IN THE LOWER 70S.

AS THE COLD FRONT MOVES THROUGH THIS AFTERNOON...EXPECT A LINE OF
SHOWERS AND A FEW THUNDERSTORMS TO MOVE ACROSS THE TN VALLEY.
ADJUSTED THE POP/WX TREND HEADING INTO THIS AFTERNOON TO ACCOUNT FOR
CURRENT RADAR/SATELLITE AND HIRES MODEL DATA TRENDS. WESTERLY SFC
WINDS WILL BE BREEZY WITH GUSTS UP TO 20 MPH THIS AFTERNOON.
PROVIDED THE LAPSE RATES FROM SFC-850MB...CANNOT RULE OUT STRONGER
WIND GUSTS OR SMALL HAIL IN ANY STRONGER STORMS LATER TODAY.

.AVIATION...
/ISSUED 623 AM CDT WED MAY 4 2016/
FOR 12Z TAFS...
A COLD FRONT CURRENTLY OVER SOUTHERN ILLINOIS WILL CONTINUE SOUTHWARD
AND ENTER THE TN VALLEY BETWEEN 18-21Z. SHOWERS AND THUNDERSTORMS ARE
EXPECTED ALONG THE FRONT BUT DUE TO THE MORE SCATTERED NATURE OF THE
THUNDERSTORMS HAVE OPTED TO GO WITH A VCTS AT BOTH TERMINALS. WINDS
AHEAD OF AND IMMEDIATELY BEHIND THE FRONT WILL BE BREEZY WITH GUSTS
UPWARDS OF 25KTS. AFTER 06Z TONIGHT SURFACE WINDS DROP BELOW 10KTS
BUT SPEEDS AROUND 2000FT ARE EXPECTED TO BE CLOSE TO 30KTS AND LLWS
MAY NEED TO BE INCLUDED IN LATER ISSUANCE`S. VFR CONDITIONS ARE
EXPECTED FOR A MAJORITY OF THE TAF PACKAGE BUT A BRIEF DROP TO MVFR
IS POSSIBLE NEAR THUNDERSTORMS.
