.DISCUSSION...
KEEPING AN EYE ON THE SNOW BANDS PUSHING ACROSS SOUTHEAST OKLAHOMA
AND NORTHEAST TEXAS THIS EVENING. BASICALLY...THESE BANDS ARE
GRADUALLY WEAKENING AS THE EVENING WEARS ON...ALTHOUGH THERE ARE
SPORADIC FLARE UPS IN THE ACTIVITY FROM TIME TO TIME. AFTER
CONTACTING A FEW LOCAL OFFICIALS WHERE SNOW IS FALLING...HAVE NOT
HEARD OF ANY PARTICULARLY LARGE ACCUMULATIONS...AND HAVE DECIDED
TO CANCEL THE WINTER STORM WARNING FOR ALL BUT MCCURTAIN
COUNTY...AND REPLACE WITH A SNOW ADVISORY. STILL THINK THERE IS A
CHANCE FOR 3 TO 5 INCHES IN THE NORTHERN HALF OF MCCURTAIN...
ESPECIALLY IN THE HIGHER ELEVATIONS. BELIEVE THAT THE AFTERNOON
FORECAST PACKAGE REMAINS OVERALL IN GOOD SHAPE THIS EVENING...AND
MADE ADJUSTMENTS OF A DEGREE OR TWO TO OVERNIGHT LOW TEMPERATURES.
/18/
&&
.AVIATION...
STRONG/GUSTY GRADIENT WINDS CONTINUE TO WRAP AROUND DEEP SURFACE LOW
PRESSURE...CENTERED JUST E OF KHRO AT 25/0100 UTC. WINDS HAVE
BECOME WESTERLY BEHIND A REINFORCING COLD FRONT MOVING E ACROSS THE
REGION. PATCHY DZ/-RA CONTINUES FALLING ACROSS MUCH OF THE FORECAST
AREA THIS EVENING...WITH SN BANDS NOTED ACROSS N TX/E OK. EXPECT SN
BANDS TO CONTINUE DECREASING IN COVERAGE AS THE COLD UPPER LOW
EJECTS TOWARD THE OH VALLEY.
LOW CIGS AND OCCASIONAL VSBY OBSTRUCTIONS WILL LEAD TO WIDESPREAD
MVFR TO IFR FLIGHT CATEGORIES AT MANY TERMINALS THROUGH AT LEAST
25/1200 UTC...AS PRECIPITATION MOVES EASTWARD. ONGOING TAFS MAY BE
A LITTLE PESSIMISTIC THOUGH...AS SATELLITE IMAGERY SHOWS A RAPID
IMPROVEMENT IN FLIGHT CATEGORIES W OF IH-35. I WILL CONTINUE TO
MONITOR AND TIMING ADJUSTMENTS MAY BE MADE FOR THE 25/0600 UTC TAF
PACKAGE. REGARDLESS OF TIMING...EXPECT IMPROVING FLIGHT CATEGORIES
TO VFR BEHIND LINGERING PRECIPITATION. GUSTY W/NW WINDS WILL LIKELY
CONTINUE THROUGH THE UPCOMING FORECAST PERIOD...RESULTING IN A NASTY
HEADWIND FOR 9 WESTWARD FLYING REINDEER AND THEIR DRIVER OVERNIGHT.
