.SYNOPSIS...
WEAK TROUGH OF LOW PRESSURE WAS LOCATED ACROSS THE EASTERN

UNITED STATES. A SERIES OF DISTURBANCES WILL ROTATE AROUND UPPER
LEVEL LOW PRESSURE TO OUR NORTH INTO EARLY NEXT WEEK BRING
UNSETTLED WEATHER FOR THE WEEKEND. THE TROF AXIS SHIFTS OFFSHORE
BRINGING IN DRIER WEATHER BY LATE TUESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
WEAK MID LVL BOUNDARY ONCE AGAIN BROUGHT SOME STRAY SHOWERS INTO
THE AREA THIS MORNING...AND WITH STEEP MID LVL LAPSE RATES SAW SOME
STRONG STORMS DEVELOP. THE BOUNDARY IS NOW S OF THE AREA AND PRECIP
HAS ENDED. THE NAM HAD DRIVEN A SFC BOUNDARY FAR S INTO THE AREA
TODAY...BUT CONDITIONS NOW FAVOR THE RUC MODELS WHICH HAS THE
BOUNDARY TO OUR N WITH THE RETURN OF S FLOW ACROSS ALL AREAS. WELL
INLAND MIXING WILL DROP TD...BUT AS S FLOW PICKS UP LATER THIS AFT
WILL SEE THEM STEADILY CLIMB INTO THE 60S. WITH THE BOUNDARY
N...WILL PUSH POPS BACK UP INTO ALL COUNTIES...THOUGH BEST CHANCE
WILL STILL LINGER ALONG THE SEA BREEZE AND FAR NE COUNTIES NEAR THE
WILDFIRE. THE SHEAR AND DYNAMICS DO NOT SUPPORT ORGANIZED STRONG
CONVECTION...BUT WITH STEEP LAPSE RATES COULD SEE SOME PULSE STORMS
NEARING SVR. THE WINDEX VALUES SUPPORTIVE OF STRONG WIND IS ABOVE 50
AND FREEZING LEVELS THANKS TO THE UPPER LVL TROF REMAIN LOW AROUND
11K FT. AIR COLUMN IS STILL DRY FROM THE LAST COUPLE DAYS...AND
THOUGH RECOVERY IS EXPECTED TODAY DONT ANTICIPATE ENOUGH TO SUPPORT
HEAVY RAIN. IN FACT...DRY SOUNDING COULD BE THE PRIMARY LIMITING
FACTOR FOR CONVECTION AT FAR INLAND LOCATIONS. TEMPS WILL BE WARMING
ANOTHER FEW DEG FROM YESTERDAY...WITH HIGHS IN THE MID TO UPPER 80S.

&&

.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
AN UNSETTLED PERIOD OF WEATHER WILL KICK IN SATURDAY WITH UPPER

RANGE MOST AREAS. WITH INCREASED CLOUD COVER...TEMPS WILL BE A FEW
DEGREES COOLER SATURDAY AND UP TO ANOTHER 3 TO 4 DEGREES COOLER ON
SUNDAY.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
WITH AXIS OF UPPER TROUGH STILL TO THE WEST OF THE CWA...WILL
MAINTAIN POPS IN THE FORECAST SUNDAY NIGHT THROUGH MONDAY BEFORE
TAPERING OFF POPS MONDAY NIGHT. BY TUESDAY TROF AXIS IS SWINGING
