AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
217 PM CDT FRI JUL 21 2006
.DISCUSSION...LITTLE CHANGE TO ONGOING FORECAST...WITH MOST OF THE
IMPACTS IN THE SHORT TERM. THE MUCH ADVERTISED COLD FRONT WILL
CONTINUE TO SHARPEN THIS AFTERNOON OVER CENTRAL AND WESTERN
OKLAHOMA...WHILE MAKING STEADY PROGRESS TO THE SOUTH. OUTFLOW FROM
OVERNIGHT CONVECTION MAY HAVE CONTRIBUTED TO A WEAK PRE FRONTAL WIND
SHIFT WHICH HAS EFFECTIVELY ELIMINATED DOWNSLOPE WARMING.
THEREFORE...DO NOT EXPECT ANY RECORD HIGHS TO FALL THIS AFTERNOON.
MORNING SOUNDINGS ALSO SHOWED INCREASED MOISTURE DEPTH AS THE RESULT
OF DEEP EASTERLY FLOW OVERNIGHT. THIS...COMBINED WITH INCREASING MID
LEVEL ASCENT...WAS CONTRIBUTING TO EARLY DEVELOPMENT OF CUMULUS
THROUGHOUT CENTRAL AND PARTS OF NORTHERN OKLAHOMA THIS AFTERNOON.
INHIBITION WAS BEING REMOVED...AND MODELS SUPPORT THE IDEA OF
ESSENTIALLY SURFACE BASED THUNDERSTORMS DEVELOPING JUST AHEAD OF THE
COLD FRONT. INSTABILITY AND LIFT FAVOR INCREASING COVERAGE EAST
ALONG THE FRONT INTO CENTRAL AND EASTERN OKLAHOMA. FARTHER NORTH AND
WEST...INSTABILITY WILL BE SLIGHTLY MORE ELEVATED BEHIND THE
FRONT...WHERE A ZONE OF INTENSE MID LEVEL LIFT SHOULD SUPPORT
ADDITIONAL SHOWERS AND A FEW THUNDERSTORMS. THE ENTIRE FRONTAL ZONE
WILL SHIFT SOUTH AND EAST WITH TIME...BRINGING AT LEAST A CHANCE FOR
RAIN TO SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS OVERNIGHT.
PREVIOUS FORECAST HAD POPS AND TIMING WELL HANDLED. ONLY CHANGE WAS
TO LOWER POPS IN FAR NORTHERN OKLAHOMA...WHERE WATER VAPOR SUGGESTS
STRONG DRYING BY EARLY EVENING.
THE HIGHLIGHTS IN EFFECT FOR EXCESSIVE HEAT AND FIRE WEATHER MATCH
WELL WITH LATEST EXPECTATIONS FOR FRONTAL TIMING AND LOCATION. WILL
LEAVE THESE HIGHLIGHTS IN EFFECT...BUT LIKELY TRIM COUNTIES AS THE
FRONT PROGRESSES THROUGH THE EVENING.
LOOKING AHEAD...THE WEEKEND WILL BE MUCH NICER WITH HIGHS BELOW 90
IN SOME AREAS ON SATURDAY...AND LOWS CLOSE TO 60 IN NORTHWEST
OKLAHOMA SUNDAY MORNING. MODELS AGREE ON THE LARGE SCALE
PATTERN...WITH MODERATE NORTHWEST FLOW SETTING UP FOR THE NEXT 7
DAYS. THIS FLOW PATTERN IS NOTORIOUS FOR PRODUCING FAST MOVING
THUNDERSTORM COMPLEXES. TIMING AND LOCATION OF THESE COMPLEXES WILL
BE VERY DIFFICULT TO PREDICT MANY DAYS IN ADVANCE...AND NOT ALL OF
THEM WILL AFFECT OKLAHOMA AND NORTH TEXAS. CURRENTLY...THE MOST
CONSISTENT SIGNAL IS FOR AN ORGANIZED SHORTWAVE TROF TO ARRIVE LATE
NEXT WEEK...WHERE POPS HAVE BEEN ADDED TO THE FORECAST. WEAKER
SIGNALS SUGGEST STORMS MAY APPROACH WESTERN OKLAHOMA FROM COLORADO
MONDAY MORNING...AND MAY DEVELOP IN WESTERN OKLAHOMA WHEN DEEPER
MOISTURE RETURNS TO THE AREA TUESDAY MORNING. WILL PLACE SOME SILENT
POPS IN THESE AREAS FOR NOW...BUT MAY NEED TO BUMP POPS UP WITH TIME.
TEMPERATURES LOOK TO SLOWLY WARM UP STARTING SUNDAY...WITH A FEW
LOWER 100 READINGS RETURNING TO WICHITA FALLS AND ALTUS BY THE
MIDDLE OF NEXT WEEK.
