SURFACE RIDGE ACROSS THE ATLANTIC OCEAN EXTENDING WESTWARD ACROSS THE
NORTHERN GULF COAST COMBINED WITH A LOW ACROSS THE KANSAS WILL
MAINTAIN INCREASED SOUTHERLY FLOW OF GULF MOISTURE THROUGH THE
MIDDLE OF THE WEEKEND. AN EASTWARD MOVING UPPER-LEVEL TROUGH
ACROSS THE DESERT SOUTHWEST INTO THE CENTRAL PLAINS WILL LEAD TO
STEEPENING LAPSE RATES ACROSS EASTERN OKLAHOMA AND NORTHEAST TEXAS
THIS EVENING AND OVERNIGHT AS HEIGHTS GRADUALLY FALL ACROSS THESE
AREAS. THE COMBINATION OF A MOIST BOUNDARY LAYER AND INCREASING
INSTABILITY ALOFT COULD ALLOW FOR SCATTERED SHOWERS AND
THUNDERSTORMS ACROSS NORTHEAST TEXAS AND SOUTHEAST OKLAHOMA
OVERNIGHT. ALTHOUGH THE ARKLATEX IS OUTSIDE OF THE SPC DAY 1
SEVERE WEATHER THREAT OUTLOOK, A FEW STRONG STORMS COULD VENTURE
INTO PORTIONS OF SOUTHEAST OKLAHOMA ALLOWING FOR GUSTY WINDS AND
POSSIBLY SMALL HAIL NEAR DAYBREAK.
ANOTHER SHORTWAVE TROUGH TO SWING EAST ACROSS THE TEXAS PANHANDLE
INTO OKLAHOMA ON WEDNESDAY EVENING ALLOWING FOR ANOTHER ROUND OF
CONVECTION ACROSS SOUTHEAST OKLAHOMA AND ARKANSAS INTO THE
OVERNIGHT HOURS. A FEW STRONG STORMS MAY BE POSSIBLE ACROSS
PORTIONS OF SOUTHEAST OKLAHOMA WITH WIDESPREAD RAINFALL EXPANDING
INTO ARKANSAS AS UPPER FORCING WANES.
CONDITIONS TO IMPROVE ON THURSDAY AS WEAK UPPER-LEVEL RIDGING
BUILDS ACROSS THE REGION. HOWEVER, SOUTHWEST FLOW TO RETURN BY
FRIDAY ALLOWING FOR INCREASED INSTABILITY AHEAD OF A FRONTAL
BOUNDARY THAT WILL MOVE ACROSS THE REGION ON SATURDAY. COULD SEE
WIDESPREAD SHOWERS AND THUNDERSTORMS ACROSS THE ENTIRETY OF THE
ARKLATEX ON SATURDAY, LINGERING ACROSS AREAS SOUTH OF INTESTATE 20
INTO SATURDAY EVENING.
