Severe Thunderstorm Warning 112, NWS Huntsville, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
127 PM CDT SUN JUN 1 2008

.DISCUSSION...A MOIST/VERY UNSTABLE AIRMASS EXISTS ACROSS THE
CENTRAL TENNESSEE VALLEY THIS AFTN. SEVERAL LOW LVL BOUNDARIES
CAN BE SEEN ACROSS THE AREA INCLUDING A NORTH-TO-SOUTH ORIENTED
OUTFLOW BNDRY THAT RESIDES JUST EAST OF I-65. THIS BOUNDARY IS A
RESULT OF THIS MORNING/S CONVECTION THAT AFFECTED PORTIONS OF NE
AL/SRN MIDDLE TN. A NICE THERMAL GRADIENT EXISTS ALONG THIS
LINE...WITH TEMPS RANGING FROM THE UPR 70S EAST TO NEAR 90F WEST.

FARTHER NORTH...THUNDERSTORMS CONTINUE TO DEVELOP ALONG A
WEST-TO-EAST ORIENTED BOUNDARY THAT IS DRAPED ACROSS SOUTHERN
TENNESSEE. SFC HEATING WITHIN AXIS OF LOW LVL CONFLUENCE AND
INSTABILITY WILL GENERATE ADDITIONAL THUNDERSTORMS SOUTH OF THIS
MAIN LINE THROUGH THE AFTERNOON HOURS. MLCAPE APPROACHING
2000 J/KG OVER NW ALABAMA WILL ALSO SUPPORT STRONG TO SEVERE
TSTMS...ESPECIALLY AROUND ANY BNDRY INTERACTION. PRIMARY THREATS
WILL BE DAMAGING WINDS AND LARGE HAIL. HOWEVER...WITH PWAT VALUES
AOA 1.75...HEAVY RAINFALL CAN BE EXPECTED...WHERE UP TO 1 INCH
OF RAIN COULD FALL IN LESS THAN 45 MINUTES.

TONIGHT...EXPECT CONVECTION TO WANE THIS EVENING WITH LOSS OF
DAYTIME HEATING AND WORKED-OVER AIRMASS. HOWEVER...LOW LVL FRONTAL
BOUNDARY WILL LINGER ACROSS THE AREA AND UPSTREAM ENERGY/H5 SPEED
MAX COULD SUPPORT REDEVELOPMENT OVERNIGHT. NOT CONVINCED A BROAD
MCS/MCC WILL MAINTAIN ITSELF ACROSS THE AREA GIVEN LACK OF LLJ...
BUT WOULD NOT BE SURPRISED TO SEE ISOLD/SCT TSTMS BREAK OUT ONCE
AGAIN TOWARD DAYBREAK.

MONDAY AND TUESDAY...ANY ONGOING CONVECTION FROM LATE TONIGHT SHOULD
GRADUALLY DISSIPATE OR MOVE SOUTHEAST OF THE AREA BY MID/LATE MRNG.
LINGERING LOW LVL BOUNDARY(IES) WILL TRIGGER ADDITIONAL SCT TSTMS
AS STRONG SFC HEATING OCCURS. MID LVL MCV/S WILL CONTINUE TO SLIDE
SOUTHEAST ACROSS THE AREA...ENHANCING UPWARD FORCING AND ORGANIZATION
FOR CONVECTION THROUGH THE DAY. PERSISTENT BOUNDARY WILL EVENTUALLY
BE FORCED BACK NORTH OF THE AREA MONDAY NIGHT AS DEEPENING SFC LOW
KICKS ACROSS THE CNTRL PLAINS. INCREASING S/SW FLOW WILL ALSO SHOVE
DEEPER MOISTURE NORTH OF THE AREA AS WELL. POP CHANCES WILL DECREASE
MON NGT/TUE...WITH ONLY A LINGERING SLT CHANCE THREAT ACROSS THE
HIGHER TERRAIN OF NE AL/SRN TN TUESDAY.

.LONG TERM (WEDNESDAY THROUGH SUNDAY)...
12Z/GFS DATA HAS BEEN DELAYED SO HAVE MADE LITTLE CHANGES TO THE
EXTENDED AT THIS TIME. EC/GFS CONTINUES TO SHOW THE STORM TRACK
REMAINING NORTH OF THE AREA THROUGH THE WEEKEND. THIS WILL RESULT
IN DRY AND WARM CONDITIONS. LWR/MID 90S WILL NOT BE OUT OF THE
QUESTION WED/THU AS UPR HIGH AMPLIFIES ACROSS THE SOUTHEAST STATES
IN RESPONSE TO DIGGING TROUGH OVER THE INTERMOUNTAIN WEST. COLD
FRONT FROM THIS SYSTEM NEVER APPEARS TO MAKE IT THIS FAR SOUTH...
SO PRECIP CHANCES REMAIN VERY LOW THROUGH THIS PERIOD. NADLER.83
