...STRONG WINDS TO IMPACT THE PANHANDLES TODAY...

.A DEEPENING SURFACE LOW PRESSURE TROUGH OVER WESTERN SECTIONS OF THE
PANHANDLES WILL CREATE A TIGHT PRESSURE GRADIENT OVER ALL OF THE
TEXAS AND OKLAHOMA PANHANDLES TODAY. IN ADDITION...A ZONE OF STRONG
WINDS JUST ABOVE THE SURFACE WILL REMAIN OVER THE PANHANDLES FOR MOST
OF THE DAY. AS DAYTIME HEATING OCCURS...THESE STRONG WINDS ABOVE THE
GROUND WILL MIX DOWN TO THE SURFACE. THUS...THE COMBINATION OF THE
TIGHT PRESSURE GRADIENT AND THE DESCENDING STRONG WINDS ALOFT WILL
RESULT IN STRONG SURFACE WINDS THROUGH MIDNIGHT FOR THE TEXAS AND
OKLAHOMA PANHANDLES.

...WIND ADVISORY REMAINS IN EFFECT UNTIL MIDNIGHT CDT TONIGHT...

A WIND ADVISORY REMAINS IN EFFECT UNTIL MIDNIGHT CDT TONIGHT FOR ALL
OF THE TEXAS AND OKLAHOMA PANHANDLES.

A TIGHT SURFACE PRESSURE GRADIENT WILL COMBINE WITH AN INTENSE BAND
OF STRONG WINDS JUST ABOVE THE SURFACE TO CREATE STRONG SOUTH TO
SOUTHWEST SURFACE WINDS THROUGH MIDNIGHT TONIGHT. WIND SPEEDS WILL
INCREASE INTO THE 35 TO 40 MPH RANGE WITH GUSTS NEAR 45 MPH. THESE
STRONG WINDS WILL ALSO CREATE AREAS OF BLOWING DUST WHICH COULD CREATE
LOW VISIBILITIES.

A WIND ADVISORY MEANS THAT WINDS OF 35 MPH ARE EXPECTED. WINDS
THIS STRONG CAN MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH
PROFILE VEHICLES. USE EXTRA CAUTION.

DISCUSSION...
SURFACE LEE TROUGH OVER SOUTHEASTERN COLORADO WILL CONTINUE TO
DEEPEN TONIGHT WHICH WILL STRENGTHEN A SOUTHERLY LOW LEVEL JET ACROSS
THE AREA TONIGHT. A DRYLINE REMAINS JUST WEST OF THE CWA AND
CURRENT SATELLITE LOOPS SHOW AN INCREASING CU FIELD. SPC HAS
AREA OUTLINED IN A GENERAL RISK WITH A SLIGHT RISK JUST NORTH OF
THE CWA. SHORT TERM MODEL GUIDANCE SUGGESTS PRECIP WILL STAY
NORTH OF CWA HOWEVER WENT AND INSERTED SLIGHT CHANCE POPS ACROSS
THE EASTERN HALF WHERE MOISTURE AND INSTABILITY ARE THE GREATEST.
WINDS WILL STAY UP TONIGHT AND WITH A WARM/MOIST AIR MASS ACROSS THE
AREA...TEMPS WILL REMAIN MILD TONIGHT WITH LOWS IN THE 60S TO AROUND
70.

LARGE UPPER TROUGH OVER THE NORTHERN ROCKIES WILL PROGRESS EASTWARD
INTO NORTHERN PLAINS WED WITH A SERIES OF SPEED MAXIMA PROPAGATING
AROUND THE BASE OF THIS TROUGH. SURFACE TROUGH WILL SLOWLY TRACK
EASTWARD DURING THE DAY WHICH WILL CAUSE A FRONTAL BOUNDARY TO HANG
UP ACROSS WESTERN KANSAS. WITH CWA IN WARM SECTOR...WENT WITH THE
WARMEST MOST GUIDANCE WITH HIGHS APPROACHING THE CENTURY MARK.
IN ADDITION A DRYLINE WILL SHARPEN AS IT MOVES OFF THE CAPROCK
LEAVING AREAS WEST IN ELEVATED FIRE CONDITIONS AS RELATIVE
HUMIDITIES LOWER INTO THE SINGLE DIGITS. ON THE OTHER HAND...
FOR AREAS OFF THE CAPROCK...CONVERGENCE ALONG THE DRYLINE MAY SET
OFF ISOLATED CONVECTION WITH GREATER MOISTURE AT THE SURFACE AND
MODEST INSTABILITY. STILL UNCERTAIN THOUGH ON STRENGTH OF THE CAP
SO LEFT POPS BELOW CATEGORICAL.

UPPER TROUGH PUSHES FURTHER TO THE EAST THU WHILE THE SURFACE LOW
PULLS AWAY FURTHER TO THE EAST. COLD FRONT PUSHES INTO THE
PANHANDLES EARLY THU BUT WILL HANG UP ACROSS THE SOUTHERN TEXAS
PANHANDLE. THE DRYLINE PUSHES OFF THE CAPROCK AGAIN WITH BEST
CHANCES FOR CONVECTION ACROSS THE EASTERN PORTION OF THE
PANHANDLES. HIGH PRESSURE BUILDS INTO THE CENTRAL PLAINS FRI AS
THE UPPER TROUGH LIFTS TOWARD THE NORTHERN GREAT LAKES. FRI SHOULD
BE THE COOLEST DAY OF THE WEEK WITH NORTHEAST UPSLOPE FLOW BEHIND
FROPA. LARGE MID/UPPER RIDGE BUILDS OVER THE DESERT SOUTHWEST OVER
THE WEEKEND AND EARLY NEXT WEEK WITH SEVERAL UPPER DISTURBANCES
MOVING INTO THE AREA ON NORTHWEST FLOW ALOFT. HARD TO PINPOINT
CONVECTIVE CHANCES THIS FAR OUT SO MAINTAINED DRY FORECAST WITH
WARMING TEMPS THROUGH THE PERIOD.

FIRE WEATHER...
SURFACE LEE TROUGH WILL FURTHER DEEPEN WED. A DRYLINE WILL PUSH
OFF THE CAPROCK WHICH WILL CAUSE RELATIVE HUMIDITIES TO FALL INTO
THE SINGLE DIGITS ACROSS THE WESTERN HALF OF THE CWA. WITH STRONG
SOUTHWEST WINDS...WENT AND UPGRADED THE FIRE WEATHER WATCH TO A RED
FLAG WARNING WED. A FRONT WILL PUSH THROUGH THU AND ALTHOUGH
RELATIVE HUMIDITIES CAN FALL BELOW 15 PERCENT OUT WEST...WIND SPEEDS
LOOK TO BE LIGHTER.
