THE HEAVIER RAINS TONIGHT WILL BE FOCUSED ALONG THE WEST VIRGINIA AND
VIRGINIA MOUNTAINS. THESE AREAS HAVE RECEIVED ABOUT 1/4 TO 1/2 INCHES OF

PROBLEMS TO DEVELOP..BUT RAPID RISES ON SMALL STREAMS AND CREEKS WILL
OCCUR AFTER ANY HEAVY DOWNPOURS.

RAINFALL WILL BE LIGHT FOR AREAS WEST OF THE MOUNTAINS..BUT WE CAN NOT
RULE OUT THE POSSIBILITY OF A THUNDERSTORM TONIGHT..SO KEEP A CLOSE
WATCH ON ANY STREAM OR CREEK AFTER ANY THUNDERSTORM.

BELIEVE IT OR NOT A DRYING TREND WILL TAKE HOLD ACROSS OUR AREA
SATURDAY NIGHT. SUNDAY..FATHER'S DAY..IS SHAPING UP TO BE PARTLY
SUNNY WITH TEMPERATURES IN THE 70S.

THE WEATHER MAPS LATE THIS AFTERNOON SHOWED A COLD FRONT THAT EXTENDED
FROM A LOW OVER MICHIGAN..THEN THROUGH WESTERN
PENNYSYLVANIA..CONTINUING ALONG THE OHIO RIVER BETWEEN WHEELING AND
HUNTINGTON..THEN TO THE FLORIDA PANHANDLE. WE WILL HAVE TO WATCH A
DISTURBANCE THAT MAY FORM ALONG THIS FRONT AND REACH SOUTHWEST VIRGINIA

BY SATURDAY AFTERNOON THE COLD FRONT AND MOST OF THE RAINS WILL BE
THROUGH OUR AREA. DRIER AIR WILL FILTER IN ALONG THE OHIO RIVER
SATURDAY AFTERNOON AND REACH THE EASTERN PORTIONS OF WEST VIRGINIA
SATURDAY NIGHT.

THE DRY WEATHER ON SUNDAY WILL BE SHORT LIVED BECAUSE THERE IS A CHANCE
OF SHOWERS AND THUNDERSTORMS AGAIN FOR MONDAY AND TUESDAY. A LOW
PRESSURE AREA SHOULD DEVELOP OVER THE CENTRAL PLAINS SUNDAY..AND
THEN MOVE EAST BRINGING OUR NEXT CHANCE OGF RAIN FOR THE BEGINNING OF THE
WORK WEEK.
