SURFACE HIGH PRESSURE AND RIDGING ALOFT OVER THE SOUTHEASTERN
CONUS WILL CONTINUE TO PROVIDE US WITH DRY AND SEASONABLY WARM
CONDITIONS THROUGH SATURDAY. A SYSTEM MOVING THROUGH THE NORTHEAST
WILL BRING A COLD FRONT INTO THE OHIO VALLEY BUT THIS FRONT WILL
STALL TO OUR NORTH. A WEAK UPPER LEVEL LOW OVER THE PLAINS WILL BE
SLOW TO MOVE THIS WEEKEND AS A BLOCKING RIDGE EXTENDS FROM THE
SOUTHEAST U.S. TO ONTARIO CANADA, BUT EVENTUALLY THE REMNANTS OF
THIS UPPER LOW WILL MAKE IT INTO THE OHIO VALLEY BY THE TUES/WED
TIME FRAME. THE ASSOCIATED WEAKNESS IN THE RIDGE OVER OUR AREA
WILL THEN MOVE OFF TO OUR EAST AS THE UPPER RIDGING RE-ASSERTS
ITSELF OVER THE REGION FOR THE END OF THE WORK WEEK.
MOISTURE WILL BE INCREASING BY SUNDAY, AND CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL RETURN TO OUR AREA AS WEAK SHORT WAVE ENERGY
MOVES ACROSS THE REGION. MODELS GENERALLY SHOW LIMITED INSTABILITY
AT BEST (OUTSIDE OF THE NAM WHICH RIGHT NOW IS AN OUTLIER), BUT PWAT
VALUES ARE FORECAST TO BE ABOVE 1.8 INCHES AT LEAST IN THE SOUTH AND
ANY CAPE WILL LIKELY BE OF THE TALL SKINNY VARIETY RESULTING IN THE
POSSIBILITY OF HEAVY RAINFALL RATES WITH ANY STORMS THAT DEVELOP.
NO STRONG SYNOPTIC FORCING IS CURRENTLY IN THE FORECAST FOR THE
COMING WORK WEEK. HOWEVER, GIVEN THE INCREASED MOISTURE AND
INSTABILITY WE WILL SEE CHANCES FOR SHOWERS AND STORMS EACH DAY
ESPECIALLY DURING THE AFTERNOON AND EVENING HOURS. RIGHT NOW, SHEAR
GENERALLY LOOKS WEAK AND CHANCES FOR SEVERE STORMS LOOK VERY LOW
OVERALL. HOWEVER, MODEL PWAT VALUES WILL BE AROUND 1.7 TO 1.8
INCHES OR MORE AT TIMES, AND THERE WILL BE THE POSSIBILITY OF VERY
HEAVY RAINFALL THAT COULD CAUSE LOCALIZED FLOODING IN ANY AREAS THAT
SEE REPEATED OR PROLONGED PERIODS OF HEAVY RAIN.
