SPECIAL WEATHER STATEMENT

655 AM CST SUN MAR 28 1993

...EARLY SPRING STORM TAKING AIM ON THE SOUTHERN PLAINS...

A MAJOR EARLY SPRING STORM WILL BE AFFECTING EASTERN OKLAHOMA BEGINNING
LATE MONDAY NIGHT AND CONTINUING INTO TUESDAY EVENING. A POWERFUL UPPER
LEVEL STORM CURRENTLY MOVING INTO CALIFORNIA IS EXPECTED TO MOVE EAST
SOUTHEAST INTO SOUTHERN NEW MEXICO BY MONDAY EVENING BEFORE BEGINNING
TO TURN NORTHEAST INTO THE TEXAS PANHANDLE BY TUESDAY MORNING. IN
RESPONSE TO THE UPPER LEVEL STORM...AN AREA OF LOW PRESSURE AT THE
SURFACE WILL DEVELOP IN EASTERN NEW MEXICO MONDAY AFTERNOON. THIS
SURFACE LOW IS THEN EXPECTED TO DEEPEN AS IT MOVES INTO THE SOUTHERN
TEXAS PANHANDLE BY TUESDAY MORNING AND TO NORTH CENTRAL OKLAHOMA
TUESDAY EVENING.

STRONG SOUTHERLY FLOW AHEAD OF THE STORM WILL TRANSPORT COPIOUS AMOUNTS
OF GULF MOISTURE NORTH INTO EASTERN OKLAHOMA. THUNDERSTORMS ARE
EXPECTED TO INCREASE IN COVERAGE AND INTENSITY ACROSS THE AREA LATE
MONDAY NIGHT OR EARLY TUESDAY MORNING AS THE STORM SYSTEM APPROACHES.
THE EXPECTED PATH OF THE SURFACE AND UPPER LEVEL STORM SYSTEMS SUGGESTS
THAT AN OUTBREAK OF SEVERE THUNDERSTORMS MAY OCCUR ACROSS EASTERN
OKLAHOMA DURING THE DAY TUESDAY.

AS THE STORM SYSTEM MOVES EAST OF THE AREA TUESDAY NIGHT...MUCH COLDER
AIR WILL BE PULLED IN BEHIND THE STORM ON GUSTY NORTH WINDS.
TEMPERATURES WILL FALL SHARPLY TUESDAY NIGHT AND HIGH TEMPERATURES
WEDNESDAY AND THURSDAY WILL BE 20 TO 25 DEGREES BELOW NORMAL FOR THIS
TIME OF YEAR. SOME LIGHT PRECIPITATION MAY WRAP AROUND THE BACK SIDE OF
THE STORM WEDNESDAY INTO THURSDAY. MOST OF THE PRECIPITATION SHOULD BE
IN THE FORM OF RAIN...BUT THE AIR MAY BE COLD ENOUGH BY THURSDAY FOR
SOME LIGHT SNOW TO MIX IN WITH THE RAIN IN NORTHEAST OKLAHOMA. CURRENT
INDICATIONS ARE THAT ANY SNOW IN NORTHEAST OKLAHOMA THURSDAY WOULD BE
VERY LIGHT AND WOULD NOT ACCUMULATE.

OVERNIGHT TEMPERATURES WILL LIKELY FALL BELOW FREEZING DURING THIS COLD
OUTBREAK. THEREFORE IT WOULD NOT BE WISE TO PLANT THOSE OUTDOOR GARDENS
JUST YET ESPECIALLY IF THEY INVOLVE TENDER PLANTS WHICH WOULD BE
SUSCEPTIBLE TO FREEZING TEMPERATURES.

STAY TUNED TO THIS STATION FOR FURTHER INFORMATION ON THIS DEVELOPING
EARLY SPRING STORM.
