DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0743 PM CDT MON OCT 06 2008
VALID 070100Z - 071200Z
...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF SRN OK AND INTO
NERN TX AND VICINITY...
...S CENTRAL AND SERN OK/THE NERN QUARTER OF TX...
WIDESPREAD SHOWERS AND THUNDERSTORMS CONTINUE IN A N-S BAND ACROSS
THE CENTRAL U.S. W OF THE MS RIVER...NEAR AND AHEAD OF A LARGE UPPER
TROUGH COMPRISED OF SEVERAL SMALLER-SCALE FEATURES.
STRONGEST STORMS -- AND THE ASSOCIATED PRIMARY SEVERE THREAT --
REMAINS OVER THE NERN QUARTER OF TX ATTM...WHERE SEVERAL
STRONG/LOCALLY-SEVERE STORMS ARE ONGOING. ACROSS THIS
REGION...MODERATE INSTABILITY AND A WIND FIELD WHICH VEERS/INCREASES
WITH HEIGHT TO AROUND 50 KT AT MID LEVELS PER EVENING RAOBS IS
SUPPORTING SUPERCELL ORGANIZATION WITH THE STRONGEST UPDRAFTS. IN
THIS REGION...HAIL AND LOCALLY-DAMAGING WINDS WILL CONTINUE -- AND
PERHAPS EVEN A TORNADO OVER THE NEXT 1-2 HOURS.
THE AXIS OF STRONGER STORMS EXTENDS ENEWD INTO THE SRN HALF OF AR
ATTM...AND THE THREAT ACROSS THIS REGION MAY CONTINUE FOR THE NEXT
FEW HOURS. HOWEVER...WEAKER INSTABILITY WITH EWD EXTENT COMBINED
WITH WEAKER WIND FIELD IN THIS REGION SUGGEST THAT THE GREATER
THREAT WILL REMAIN FURTHER WSWWD ACROSS THE ARKLATEX REGION AND INTO
TX.
FURTHER N...AN OVERALL LACK OF INSTABILITY IS INDICATED...AND WITH
DIURNAL COOLING/STABILIZATION IN THE LOWER TROPOSPHERE...AND
LINGERING HAIL THREAT SHOULD DECREASE SLOWLY WITH TIME THROUGH THIS
EVENING.
