AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
100 PM CDT FRI JUN 24 2011

.AVIATION...BREEZY SOUTH WINDS THROUGH THE PERIOD...WITH DIURNAL
VARIATION IN SPEED. STRONG GUSTS THIS AFTERNOON AND EVENING...
ABOVE 30 KNOTS...IN WESTERN OKLAHOMA. A LOW LEVEL JET OF 50 TO 55
KNOTS OVERNIGHT RAISES SOME CONCERN OVER LLWS...BUT SURFACE SPEEDS
ARE FORECAST TO REMAIN ABOVE 12 KT...WITH RELATIVELY LITTLE
TURNING OF WIND DIRECTION WITH HEIGHT. WILL NOT INCLUDE LLWS AT
THIS TIME.

&&

PREV DISCUSSION... /ISSUED 334 AM CDT FRI JUN 24 2011/

DISCUSSION...
CONTINUED HOT AND DRY WITH LITTLE OR NO RELIEF IN SIGHT OVER THE
NEXT WEEK OR SO. RAIN CHANCES WILL BE NONZERO BUT VERY SLIM MOST
AREAS. ISOLATED LOCALES N OF WELL-DEFINED SFC FRONT ACROSS N OK
MAY MEASURE .01 OR SO EARLY THIS MORNING FROM THE STUFF MOVING SE
OUT OF KS. FRONT IS FORECAST TO LIFT N INTO KS LATER TODAY... WHICH
WILL DROP RAIN CHANCES HERE FROM SLIM TO NONE. RAIN CHANCES THEN
VARY BETWEEN SLIM AND NONE OVER THE NEXT 7 DAYS... MOST LIKELY
PEAKING AROUND 20 PCT MONDAY NIGHT WHEN THE ECMWF SAGS ANOTHER
WEAK FRONT INTO N OK. BUT IN GENERAL THE CHANCE OF RAIN WILL
LIKELY DIMINISH AS THE UPPER HIGH OVER NW MEXICO MOVES TO A MORE
DOMINANT POSITION OVER TX BY EARLY NEXT WEEK.

THE EXCEPTIONALLY DRY CONDITIONS CURRENTLY AFFECTING MUCH OF THE
AREA... WITH LITTLE OR NO CHANCE OF MEANINGFUL RELIEF... MAY LEAD
TO A PROLONGED PERIOD OF TEMPERATURES THAT COULD RIVAL SOME OF THE
MORE NOTABLE HEAT WAVES SINCE THE DUST BOWL YEARS. DEWPOINTS IN
GENERAL HAVE BEEN HELD DOWN OVER THE AREA BY THE DRY GROUND
CONDITIONS... WHICH KEEPS THE HEAT INDICES DOWN BUT ALLOWS ACTUAL
AIR TEMPERATURES TO SKYROCKET. THERE WILL BE RELATIVELY SMALL
VARIATIONS FROM DAY TO DAY... DUE MAINLY TO CHANGES IN DEWPOINTS
OR CLOUDS OR THE STRENGTH OF THE E-W/DOWNSLOPE WIND COMPONENT. BUT
IN GENERAL LOOK FOR DAYTIME HIGHS TO INCREASE GRADUALLY UNTIL OR
UNLESS THERE IS A MORE SUBSTANTIAL CHANGE IN THE PATTERN. HEAT
INDICES ARE FORECAT TO FLIRT WITH 105 IN OUR SW TODAY... AND THEY
ALSO WILL BE ON A GENERAL INCREASE FROM DAY TO DAY. HEAT-RELATED
HEADLINES WILL LIKELY BE NEEDED AT SOME POINT... PERHAPS AS EARLY
AS THIS WEEKEND BUT ALMOST CERTAINLY BY THE MIDDLE OF NEXT WEEK
WHEN PROJECTED HEAT INDICES OF 105-110 SPREAD OVER A LARGER PART
OF W AND CENTRAL OK. WE WILL CONTINUE TO ADDRESS THE POTENTIAL FOR
HEAT-RELATED ILLNESS IN THE HWO.

ALONG WITH THE HEAT WILL COME A CONTINUED ENHANCED RISK OF
WILDFIRES. WE HAD A COUPLE BAD ONES FLARE UP THURSDAY... AND MORE
COULD OCCUR GIVEN THE EXTREME HEAT AND DRYNESS. WINDS LIKELY TO BE
A BIT STRONGER TODAY THAN ON THURSDAY. RED FLAG WARNING IS
CONTINUED FOR W OK AND OUR TX ZONES THIS AFTERNOON. MORE FIRE
WEATHER HEADLINES MAY BE NEEDED OVER THE WEEKEND FOR PARTS OF OUR
WESTERN CWA... BUT AT THIS TIME IT IS DIFFICULT TO DETERMINE WHERE
THE RH AND WIND-SPEED CRITERIA ARE MOST LIKELY TO OVERLAP ON A
GIVEN AFTERNOON. SUFFICE TO SAY THAT APPROPRIATE AGENCIES SHOULD
REMAIN ON ALERT THROUGH THE WEEKEND.
