What happened

The episode as NWS SHV wrote it up.

An early spring winter storm affected portions of the region over the first official weekend of spring. A potent upper level low pressure wrapped in cold arctic air at the same time tapping into moisture and wrapping it around the north and west side of the low. As a result, light to moderate snow fell across portions of the area. Heavy snow was reported across southeast Oklahoma in McCurtain County where up to 6 inches was reported. Elsewhere, snow totals ranged from near trace amounts to near 4 inches. While the event was not considered significant for most areas, there were a number of traffic accidents across the region.

Some snowfall totals in inches across Northeast Texas: Marshall 1.00, Quitman 0.50, Mount Pleasant 1.50, Tyler 0.20, Yantis 1.50, 5 miles north of Tyler 0.50, 8 miles south of Tyler 0.50, 1 mile west of Longview 0.50, Lake Fork 2.00, Lake Cypress Springs 1.00, 2 miles southwest of Lindale 1.50, Lindale 2.00, Clarksville 4.00, New Boston 0.50, 6 miles south of Gilmer 1.00, Daingerfield 0.20, 5 miles east of Chireno 1.00.

Some snowfall totals in inches across Southeast Oklahoma: Broken Bow 3.00, Idabel 1.50, Battiest 6.00.

Some snowfall totals in inches across Southwest Arkansas: Nashville 0.20, De Queen 0.20, Ashdown 0.80, Hope 0.20.

Some snowfall totals in inches across Northwest Louisiana: Shreveport 0.10.

.DISCUSSION...
COLD CORE LOW CONTINUES TO DEEPEN ACROSS SRN OK/N TX THIS
EVENING...AND WILL CONTINUE TO DRIFT E TO JUST E OF TXK BY 12Z SUNDAY.
ALREADY HAVE RECEIVED QUITE A FEW REPORTS OF A RA/IP/SN MIX ACROSS
MUCH OF NE TX/EXTREME SW AR/SE OK...AND JUST NOW...IN THE SHV METRO
AREA...AS THE COLUMN CONTINUES TO COOL IN RESPONSE TO STRONG COLD
ADVECTION IN WAKE OF THE COLD FRONT THAT PUSHED THROUGH THE REGION
EARLIER TODAY. ALREADY BEGINNING TO SEE COOLING CLOUD TOPS ON THE IR
IMAGERY NE OF THE LOW CENTER ACROSS NW AR/NE OK THIS EVENING...WITH
THIS SNOW FILLING IN AND WRAPPING S ALONG THE BACKSIDE OF THE LOW AS
IT DRIFTS INTO THE 3 STATE AREA LATE. REPORTS OUT OF THE DFW METROPLEX
THIS EVENING HAVE ALREADY YIELDED 1-2" OF SNOW ALREADY...WITH THIS
SNOW BAND EXPECTED TO EXPAND IN COVERAGE/POSSIBLY INCREASE IN
INTENSITY ACROSS THE MUCH OF THE CURRENT WINTER STORM WARNING AREA
LATE TONIGHT/SUNDAY MORNING. SHORT TERM PROGS REMAIN PERSISTENT WITH
VERY STEEP LAPSE RATES BETWEEN 7.5-8.5 C/KM NEAR THE LOW CENTER
SUNDAY MORNING...WHICH COULD RESULT IN AREAS OF THUNDERSNOW ACROSS
EXTREME WRN AR/SE OK/NE TX...THUS ENHANCING SNOWFALL RATES. THIS...AND
THE FACT THAT THE SNOW WILL BE MOVING/DEVELOPING ACROSS THE
WARNING/PORTIONS OF THE ADVISORY AREA WHEN TEMPS WILL BE THEIR COLDEST
WILL RESULT IN SOME ACCUMULATIONS...MAINLY ON GRASSY AND ELEVATED
SURFACES.

STILL LOOKING FOR SNOWFALL ACCUMULATIONS OF 2-5" ACROSS MUCH OF THE
WARNING AREA...WITH ISOLATED AMOUNTS OF 6-7" POSSIBLE ACROSS NRN
MCCURTAIN CO. OK...GIVEN THE GREATER FORCING/COLDER TEMPS. FARTHER
S ACROSS E TX AND E INTO SW AR/EXTREME NRN LA...BELIEVE THAT SNOWFALL
TOTALS OF 1-3 INCHES WILL BE POSSIBLE...WITH LIGHTER AMOUNTS
ESPECIALLY ALONG THE I-20 CORRIDOR OF N LA. HAVE EXPANDED THE WINTER
WX ADVISORY TO INCLUDE SMITH CO. TX...GIVEN THAT THE LEADING EDGE OF
THE WRAP AROUND SNOW IS JUST A FEW COUNTIES TO THE W...AND SFC TEMPS
ARE EXPECTED TO BE NEAR FREEZING. AM A LITTLE MORE SKEPTICAL OF THE
ADV AREA FARTHER E ACROSS N LA...AS TEMPS SHOULD BE IN THE MID/UPPER
30S WHEN THE WRAP AROUND SNOW ARRIVES SUNDAY MORNING. BUT IT WILL ONLY
TAKE A BRIEF BURST OF SNOW FOR IT TO ACCUMULATE...SO WILL MAINTAIN
THE ADV. AS IS...WITH THE EXCEPTION OF UNION CO. AR AND UNION PARISH
LA...AS TEMPS HERE WILL CERTAINLY REMAIN WELL ABOVE FREEZING
TONIGHT/SUNDAY MORNING...AND THE HEAVIER SNOWFALL SHOULD REMAIN JUST W
OF THESE AREAS SUNDAY MORNING/EARLY AFTERNOON W OF THE CENTER OF THE LOW.

THE SNOW SHOULD DIMINISH SUNDAY AFTERNOON AS DRIER AIR WRAPS AROUND
THE CENTER OF THE CLOSED LOW...ALTHOUGH HAVE LOWERED MAX TEMPS ACROSS
MUCH OF THE WARNING AREA SUNDAY GIVEN THE EXPECTED SNOWPACK/GUSTY WNW
WINDS...AND POTENTIAL FOR LIGHT LINGERING WRAP AROUND PRECIP. THIS
PRECIP. SHOULD WRAP UP SUNDAY EVENING AS THE LOW SHIFTS E AWAY FROM
THE REGION...WITH EVEN MORE OF A LIQUID CHANGEOVER POSSIBLE ACROSS MUCH
OF THE AREA AS SLIGHTLY WARMER AIR IS ENTRAINED INTO THE AREA.

THE CURRENT LAKE WIND ADV. STILL LOOKS GOOD THROUGH SUNDAY
EVENING...BUT DID MAKE A FEW MINOR TWEAKS TO MIN TEMPS TONIGHT AS WELL
PER CURRENT OBS.

CURRENT SUITE OF FORECAST/ADVISORY PRODUCTS ARE AVAILABLE...GRIDS WILL
