AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
931 PM CDT THU AUG 2 2012
...UPDATE...
.DISCUSSION...
WELL DEFINED OUTFLOW BOUNDARY HAS PUSHED TO NEAR A PAWNEE TO JAY
LINE...AND CONTINUES TO SLOWLY WORK SOUTHWARD. ISOLATED CONVECTION
HAS RECENTLY FIRED ALONG THE BOUNDARY BOTH ACROSS NE OK / NW AR
BUT ALSO FURTHER WEST ACROSS NW OK. WILL MAINTAIN LOW PRECIP
CHANCES OVERNIGHT THOUGH COVERAGE WILL LIKELY REMAIN RATHER LOW.
ALSO UPDATED WINDS NEARER THE RUC OUTPUT WHICH IS SLIGHTLY FURTHER
SOUTH WITH THE BOUNDARY OVERNIGHT. THIS BRINGS MORE OF A
NORTHEASTERLY WIND ACROSS THE TULSA METRO...WHICH WILL IMPACT THE
PLACEMENT OF THE URBAN HEAT ISLAND PLUME AND CORRESPONDING
ADJUSTMENTS WERE MADE WHICH LOWERED KTUL AND RAISED KRVS VALUES.
