AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORMAN OK
747 PM CST MON FEB 10 2014

.UPDATE...
WILL INCREASE SNOW TOTALS TONIGHT INTO TUESDAY MORNING TO NEAR
4 INCHES NEAR BUFFALO...ALVA...AND CHEROKEE. PLAN TO ADJUST
PRECIPITATION CHANCES TONIGHT.

&&

.DISCUSSION...
SNOW AND FREEZING DRIZZLE REMAIN THE BIGGEST CONCERNS TONIGHT
INTO TUESDAY.

LATEST RADARS INDICATED A NARROW BAND OF MODERATE TO PERHAPS
HEAVY SNOW FROM MEADE KANSAS TO ALVA AND CHEROKEE OKLAHOMA. WOULD
NOT BE SURPRISED IF THIS BAND PRODUCED SNOW RATES NEAR 1 INCH PER
HOUR FOR THE NEXT 2-3 HOURS. AS A RESULT...INCREASED TOTAL SNOW
AMOUNTS TO NEAR 4 INCHES IN THE ADVISORY IN THESE AREAS. THE
NAM12/HRRR SEEM TO HAVE A GOOD HANDLE OF THIS BAND DUE TO WARM AIR
ADVECTION/ISENTROPIC LIFT AROUND 700 MB. THIS BAND IS FORECAST TO
SLOWLY SHIFT SOUTHEAST OVER THE NEXT FEW HOURS...BUT WEAKEN. IF
THIS BAND CAN HOLD TOGETHER FOR AWHILE...COULD UPGRADE TO WINTER
STORM WARNING WITH LOCAL SNOW AMOUNTS OVER 4 INCHES...BUT THIS
APPEARS UNLIKELY.

OTHERWISE...SNOW TOTALS APPEAR TO BE IN FINE SHAPE. APPEARS THE
OKLAHOMA CITY METRO WILL BE AFFECTED MAINLY BETWEEN MIDNIGHT AND 9
AM WITH AROUND AN INCH OF SNOWFALL WITH SLIGHTLY HEAVIER AMOUNTS
NORTH AND LOWER AMOUNTS SOUTH. CURRENT SNOWFALL TOTALS OF AROUND
ONE INCH ACROSS SOUTHWESTERN OKLAHOMA AND WESTERN NORTH TEXAS MAY
BE A BIT HIGH AS NOT SURE ANOTHER BAND OF SNOW WILL DEVELOP IN
THESE LOCATIONS LATE TONIGHT INTO TUESDAY MORNING.

FREEZING DRIZZLE CONTINUES AND WILL CONTINUE ACROSS WESTERN
NORTH TEXAS AND SOUTHERN OKLAHOMA...MAINLY SOUTH OF A ELK CITY
TO LAWTON TO ATOKA LINE THROUGH AT LEAST TUESDAY MORNING. LATEST
MODELS SUGGEST THIS LIGHT PRECIPITATION MAY TRANSITION TO A MIX
OF LIGHT FREEZING DRIZZLE... LIGHT SLEET...AND LIGHT SNOW LATER
TONIGHT WEST TO EAST. ANY PRECIPITATION AMOUNTS WILL REMAIN
LIGHT IN THESE AREAS...BUT ROADS WILL REMAIN ICY IN THESE
LOCATIONS.

CURRENT WINTER WEATHER ADVISORY IS IN GOOD SHAPE.

PRODUCTS WILL BE UPDATED SHORTLY.

.PREV DISCUSSION... /ISSUED 534 PM CST MON FEB 10 2014/

DISCUSSION...
THE 00Z AVIATION DISCUSSION FOLLOWS....

AVIATION...
ANOTHER COLD...MURKY NIGHT IS IN STORE FOR OK AND N TX TONIGHT.
AREAS OF -SN AND -FZDZ ARE LIKELY THROUGHOUT THE REGION...WITH
MAINLY -SN N OF I-40...AND -FZDZ TO THE S. AS THE UPPER-LEVEL WAVE
RESPONSIBLE FOR THIS MUCK ADVANCES E TOMORROW...THE AREAS OF -SN
AND -FZDZ WILL DIMINISH IN THE MORNING...AND WE SHOULD SEE RISING
CEILINGS AND VISIBILITIES BY LATE MORNING AT ALL SITES...PROBABLY
RETURNING TO VFR LEVELS BY 18Z.

PREV DISCUSSION... /ISSUED 359 PM CST MON FEB 10 2014/

DISCUSSION...
PRIMARY FORECAST CONCERN WILL BE IMPACTS OF FREEZING DRIZZLE AND
SNOW ACROSS THE REGION OVERNIGHT THROUGH TUESDAY.

CURRENTLY... TEMPS THROUGH 3PM HAVE WARMED SLOWLY INTO THE LOW TO
MID 20S. WIDESPREAD FZDZ...WHICH WRECKED HAVOC ON TRAVEL THIS
MORNING... TAPERED OFF THROUGH THE EARLY AFTERNOON... WITH PATCHY
FZDZ PERSISTING ACROSS PORTIONS OF CENTRAL AND SRN OK THROUGH EARLY
THIS EVENING. UPSTREAM...AN AREA OF LIGHT SNOW IS CONTINUING TO
DEVELOP ACROSS SERN CO/SWRN KS... WITH WEAK BANDING BEGINNING FROM
NEAR LIBERAL BACK TO NEAR JOHNSON CITY.

IF ALL GOES TO PLAN... AND IT RARELY DOES... THE CURRENT AREA OF
SNOW ACROSS SWRN KS WILL MOVE S/SE INTO NWRN OK THROUGH THE EVENING
AS THE H500 SHORTWAVE CONTINUES TO TRAVERSE E/SE ACROSS SRN CO/NRN
NM. AS MANY ARE AWARE... GUIDANCE HAS HAD A ROUGH GO OF IT TRYING TO
LOCKDOWN ON A CONSISTENT SOLUTION. WITH DEVELOPMENT ON GOING...
FAIRLY CONFIDENT IN FLURRIES/LIGHT SNOW REACHING FAR NWRN OK BETWEEN
2230 AND 2330Z (430-530PM CST). THE GFS HAS CONTINUED TO BE THE MORE
AGGRESSIVE SOLUTION W/REGARDS TO QPF/SN... WITH THE 18Z NAM COMING IN
MORE AGGRESSIVE AS WELL. COMPARING THE RECENT GFS/ECMWF/NAM AND THE
CURRENT TRACK OF THE H50O SHORTWAVE... A COMPROMISE SEEMS IN ORDER.
BEST CHANCES FOR ACCUMULATING SNOW WILL BE ACROSS NWRN OK... WEST OF
I-35 AND ALONG AND NORTH OF THE US-60 CORRIDOR... OR FROM ENID TO
WOODWARD AND ADJACENT LOCATIONS. LIGHT TO MODERATE SNOWFALL WILL
OCCUR FROM NEAR 6PM TO 3AM... AND DEPENDING ON BANDING... AN AVERAGE
OF 1-2 INCHES CAN CURRENTLY BE EXPECTED IN THIS AREA THROUGH TUE
MORNING. ACROSS CENTRAL OKLAHOMA AND LOCATIONS EAST OF I-35 IN NRN
OK...LIGHT FREEZING DRIZZLE AND POSSIBLY FLURRIES... WILL INCREASE
IN INTENSITY THROUGH THE EVENING... TRANSITIONING OVER TO LIGHT SNOW
TONIGHT TROUGH NOON TMRW. ONCE AGAIN... DEPENDING ON MESOSCALE
BANDING... IF ANY... ACCUMULATIONS ON AVERAGE WILL BE FROM A DUSTING
TO AN INCH OVERNIGHT THROUGH TUESDAY.

THE STORY IS A BIT DIFFERENT FOR SRN OK AND WRN N TX. IF YOU
RECALL... GUIDANCE OVER THE WEEKEND DEVELOPED A BAND OF SNOW OFF THE
NRN CAPROCK ALONG THE RED RIVER. THE GFS HAS KEPT THIS FEATURE...
AND GIVEN CONSISTENCY... KEPT CHC POPS ACROSS THE REGION. OVERALL...
WORKING TOP DOWN... A WARM NOSE WILL REMAIN IN PLACE ABOUT 3 TO 5KM
DEEP ON AVERAGE ACROSS TEXOMA. NOT BEING OVERLY IMPRESSED WITH THE
ISENTROPIC RESPONSE... SLEET WILL BE DIFFICULT TO GENERATE
TONIGHT... SO KEPT IT SIMPLE... EXPECTING SNOW/FREEZING DRIZZLE
POSSIBLE OVERNIGHT... INCREASING AFTER MIDNIGHT THROUGH TMRW AFTN.
IF A BAND OF SNOW DOES DEVELOP... AMOUNTS COULD REACH AN INCH... BUT
MOST WILL LIKELY SEE ONLY A DUSTING.

REMAINING SNOW AND FZDZ WILL TRACK E/SE THROUGH THE AFTN ACROSS S.
CENTRAL OK/SERN OK... WITH FLURRIES LINGERING THROUGH SUNSET
TOMORROW ACROSS SERN OK.

OF NOTE... THE IMPACTS OF FREEZING DRIZZLE MAY OUTWEIGH THOSE OF
SNOW FOR MANY ACROSS THE REGION. BE CAUTIOUS WHILE DRIVING... ICY
ROADWAYS AND SIDEWALKS DUE TO FREEZING DRIZZLE CAN CATCH PEOPLE
OFF GUARD. IF YOU HAVE TO TRAVEL... LEAVE EARLY... SLOW DOWN...
GIVE PLENTY OF ROOM.

FOR THE REST OF THE WEEK... EXPECT DRY CONDITIONS... AND
TEMPERATURES SLOWLY WARMING UP EACH DAY. EXPECTING 60S BY THE
WEEKEND... WITH EVEN 70S POSSIBLE ACROSS SWRN OK/WRN N TX
ON SATURDAY.
