AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
256 AM CDT THU JUL 26 2012

.DISCUSSION...

FAIRLY COMPLICATED SHORT TERM FORECAST TODAY...WITH APPROACHING
FRONT...EXPECTED AND ONGOING CONVECTION...AND PRESENCE OF
CONVECTIVE DEBRIS AND BOUNDARIES ALL COMPLICATING THINGS.

FRONTAL BOUNDARY CURRENTLY STRETCHES FROM THE NORTHERN TEXAS
PANHANDLE THROUGH NORTHWEST OKLAHOMA AND NORTHEASTWARD TOWARD
KANSAS CITY. THUNDERSTORMS HAVE BUBBLED ALONG THE SYNOPTIC
BOUNDARY ALL NIGHT...WITH SMALL STORMS DEVELOPING ALONG OUTFLOW
BOUNDARIES JUST NORTH OF THE KANSAS/OKLAHOMA BORDER. WHILE
COVERAGE SHOULD NOT BE ALL THAT GREAT IN OUR AREA DURING THE
MORNING HOURS...SOME OF THIS DEVELOPMENT COULD MAKE INTO PARTS OF
NORTHEAST OKLAHOMA. ADDITIONAL THUNDERSTORM DEVELOPMENT IS
EXPECTED DURING THE AFTERNOON ACROSS AREA...WITH POTENTIAL FOR
SEVERE STORMS FEATURING DAMAGING DOWNBURST WINDS. INCREASED
THUNDERSTORM CHANCES WILL CONTINUE INTO THE OVERNIGHT...AND AGAIN
ON FRIDAY IN THE SOUTHERN HALF OF THE AREA.

TEMPERATURES TODAY WILL BE MOST PROBLEMATIC NORTH OF INTERSTATE
40...WHERE INCREASED CLOUDS AND THE PROXIMITY OF THE FRONT AND
ASSORTED CONVECTIVE BOUNDARIES SHOULD ALL COMBINE TO LEAD TO
TEMPERATURES SEVERAL DEGREES COOLER THAN YESTERDAYS. TO OFFSET
THIS...HOWEVER...DEW POINTS SHOULD BE INCREASED DURING THE
AFTERNOON...WHICH STILL COULD YIELD HIGH HEAT INDEX
VALUES...ALTHOUGH THIS IS CERTAINLY NOT A GIVEN. SOUTH OF
INTERSTATE 40...CONFIDENCE IS HIGHER THAT DANGEROUS HEAT INDEX
VALUES WILL BE SEEN...AND THEREFORE...A HEAT ADVISORY HAS BEEN
POSTED FOR THE LATE MORNING...THROUGH THE AFTERNOON...AND INTO
EARLY EVENING. WILL PASS ALONG TO THE DAY SHIFT THE CONCERNS ABOUT
THE NORTHERN HALF OF THE AREA...AND DEPENDING ON HOW THE
FRONT/BOUNDARIES AND CONVECTION BEHAVE THROUGH THE REST OF THE
MORNING...ADDITIONAL COUNTIES MAY BE ADDED TO THE ADVISORY LATER
TODAY.

FIRE WEATHER WILL REMAIN A CONCERN...MAINLY FOR THE SOUTHERN HALF
OF THE AREA...ALTHOUGH THE OVERALL THREAT WILL BE REDUCED FROM THE
LAST TWO DAYS. MINIMUM RELATIVE HUMIDITIES WILL BE SLIGHTLY
HIGHER...AND WIND SPEEDS WILL NOT BE AS GREAT...LESSENING THE FIRE
SPREAD POTENTIAL. WILL STILL ISSUE A FIRE DANGER STATEMENT FOR
PORTIONS OF THE AREA...FOCUSING ON THE AREA SOUTH OF INTERSTATE
40.

TEMPERATURES FOR THE FRIDAY AND SATURDAY TIME FRAMES WILL BE
DEPENDENT ON HOW MUCH AND WHERE RAIN FALLS TODAY. WITH SCATTERED
COVERAGE EXPECTED...THE RAIN FOOTPRINT SHOULD BE FAIRLY
SPOTTY...AND AS A RESULT...IT IS LIKELY THAT CURRENTLY FORECAST
TEMPERATURES IN SOME LOCAL AREAS ARE SOMEWHAT OVERDONE. DO NOT
EXPECT THE RAIN WILL BE HEAVY ENOUGH THAT IT WILL AFFECT LOCAL
TEMPERATURES FOR MORE THAN A COUPLE OF DAYS HOWEVER.

A STRONGER RIDGE IS EXPECTED TO ASSERT ITSELF FOR THE WEEKEND AND
INTO EARLY NEXT WEEK...LEADING TO ANOTHER PROLONGED PERIOD OF
INTENSE HEAT. ANOTHER ROUND OF HEAT ADVISORIES/WARNINGS WILL BE
LIKELY. DURING THIS TIME FRAME...THE POSSIBILITY OF
ISOLATED...MAINLY HIGH TERRAIN...CONVECTION DOES EXIST...BUT NOT
ENOUGH TO MENTION IN THE FORECAST AT THIS TIME.

DURING THE DAY THURSDAY AND STALL OUT ON FRIDAY. THUNDERSTORMS
SHOULD DEVELOP ALONG THE BOUNDARY...WITH CONDITIONS APPEARING
FAVORABLE FOR DAMAGING DOWNBURST WINDS ESPECIALLY THURSDAY AFTERNOON.

BEHIND THE FRONTAL BOUNDARY...A RIDGE OF HIGH PRESSURE LOOKS TO
AGAIN SET UP OVER THE REGION DURING THE WEEKEND. THIS WILL ALLOW
FOR TRIPLE DIGIT TEMPERATURES AND VERY HIGH FIRE WEATHER DANGERS
TO RETURN ACROSS THE REGION AND CONTINUE INTO THE FIRST PART OF THE
NEXT WORK WEEK.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
LOCAL SPOTTER ACTIVATION IS LIKELY THURSDAY AFTERNOON TO REPORT
ON POSSIBLE DOWNBURST DAMAGE. RESPONSE EFFORTS WILL SHIFT AGAIN
TOWARD EXCESSIVE HEAT AND WILDFIRES BY THE WEEKEND.
