    ...SNOW ADVISORY FOR THE PANHANDLE TONIGHT...

A SNOW ADVISORY REMAINS IN EFFECT FOR THE OKLAHOMA PANHANDLE TONIGHT
WHERE SNOWFALL ACCUMULATIONS ARE EXPECTED TO TOTAL UP TO THREE INCHES.
MODERATE SNOW WAS FALLING IN BOISE CITY AT MIDAFTERNOON. THE SNOW IS
EXPECTED TO SPREAD EASTWARD ACROSS THE PANHANDLE THIS EVENING CREATING
SLICK ROADS AND HAZARDOUS DRIVING CONDITIONS. SOME BLOWING AND DRIFTING
OF THE SNOW IS LIKELY THIS EVENING AS WINDS GUST IN EXCESS OF 30 MPH.

IN CONTRAST...SHOWERS AND THUNDERSTORMS WILL BE SCATTERED ACROSS EASTERN
OKLAHOMA. A FEW OF THESE STORMS MAY BECOME SEVERE ACROSS THE SOUTHEAST
ONE-THIRD OF THE STATE. HAIL AND STRONG WINDS WILL BE THE PRIMARY
THREAT.

THE VARIETY OF WEATHER IS THE RESULT OF A STORM SYSTEM MOVING INTO THE
SOUTHERN PLAINS FROM THE SOUTHERN ROCKIES. A SURFACE LOW PRESSURE
CENTER WAS LOCATED WEST OF GAGE WITH A COLD FRONT EXTENDING
NORTHWARD ACROSS EASTERN KANSAS AND WESTWARD ACROSS THE TEXAS
PANHANDLE. RELATIVELY WARM MOIST AIR CONTINUED TO FLOW INTO EASTERN
OKLAHOMA FROM THE GULF OF MEXICO WHILE DRY AIR WAS BEGINNING TO
INVADE SOUTHWEST OKLAHOMA FROM WEST TEXAS.

AS THE EVENING PROGRESSES THE LOW PRESSURE SYSTEM WILL TRACK
NORTHEASTWARD KEEPING SIGNIFICANT SNOWFALL CONFINED TO THE PANHANDLE.
THE COLD FRONT ACROSS THE TEXAS PANHANDLE WILL DROP SOUTHWARD AS THE
LOW PASSES BRINGING GUSTY NORTH WINDS AND COLDER AIR INTO THE STATE.
THE CONTINUED INVASION OF DRY AIR INTO SOUTHWEST OKLAHOMA WILL
LIMIT THE CHANCES OF SIGNIFICANT RAINFALL THERE THIS EVENING AND
IN EASTERN OKLAHOMA LATER TONIGHT AS THE DRY AIR SPREADS EAST.
CLEARING SKIES AND COOL TEMPERATURES ARE EXPECTED ON THURSDAY AS THE
STORM SYSTEM EXITS THE REGION.

LATER STATEMENTS AND FORECASTS WILL BE ISSUED BY THE NATIONAL
WEATHER SERVICE AS CONDITIONS WARRANT.
