LONG TERM (FRI NIGHT THROUGH NEXT WED)...
FORECAST TRENDS CONTINUE TO SHOW THE UPPER LEVEL PATTERN
MAINTAINING A MEAN LONG WAVE TROUGH JUST OFF THE EAST COAST,...AND
ANOTHER ONE NEAR THE WEST COAST OF THE CONUS...WITH A MEAN RIDGE
OVER THE CENTRAL PART OF THE COUNTRY. A RATHER VIGOROUS SHORT WAVE
IS FORECAST TO DROP INTO THE MEAN TROUGH OFF THE EAST COAST AT THE
END OF THIS WEEK...SHARPENING THE PATTERN AND SHIFTING THE RIDGE
WESTWARD. THE SHORT WAVE WILL EXIT OVER THE WEEKEND...ALLOWING THE
UPPER RIDGE TO TEMPORARILY REBUILD A LITTLE FURTHER EASTWARD
AGAIN. THE AMPLIFIED PATTERN WILL SUPPORT A WEAKENING COLD FRONT
PUSHING INTO THE SOUTHEAST THIS WEEKEND. HOWEVER...EXPECT THE
FRONT TO STALL NORTH OF THE AREA AND SLOWLY WASH OUT.
MEANWHILE...THE SURFACE RIDGE AXIS WILL REMAIN TO THE
SOUTH...PROVIDING A CONTINUING LOW LEVEL FLOW OF MOISTURE
NORTHWARD ACROSS THE AREA. TEMPERATURES WILL BE NOT QUITE AS HOT
NEXT WEEK...TRENDING DOWNWARD BUT STILL REMAINING A LITTLE ABOVE
CLIMO. POPS WILL TREND HIGHER FURTHER NORTH...DEPENDING UPON WHERE
THE FRONT STALLS. TO THE SOUTH OF THE FRONT...POPS WILL BE NEAR
CLIMO AND ENHANCED BY THE SEABREEZE.
