NATIONAL WEATHER SERVICE NASHVILLE TN
335 AM CDT SUN MAR 18 2012

.DISCUSSION...A WEAK SHORTWAVE OVER THE OH/TN VALLEYS CONTINUES TO 
TRAVEL NEWD...PUSHING MOST OF THE MID/HI LEVEL MOISTURE INTO THE
UPPER OH VALLEY AND GREAT LAKES. THUS I HAVE SHOWN A DECREASING
POP FOR TODAY AS THE DRIER AIR MOVES IN. I KNOW...I ENDED A
SENTENCE WITH A PREPOSITION...BUT..ACCORDING TO "GRAMMAR GIRL"
IT'S SOMETIMES OK TO DO THAT.{:)

LOOKING WEST...THE UPPER TROUGH ALONG THE WEST COAST IS LOOKING
VERY BODACIOUS. FOR THE MIT GRADS...THATS DEEP...ENERGETIC AND
NEGATIVELY TILTED. MOTHER NATURE PULLS MOST OF THE TROUGH NEWD
THROUGH THE NRN ROCKIES/PLAINS. BUT WAIT...SHE FORGOT SOMETHING
AND BY WED AM IT'S SITTING OVER THE SRN PLAINS. IT'S LIKE SHE
DIDN'T BRING HER DOGGIE BAG AND JUST DECIDED TO DISCRETELY WALK
AWAY.

SO THE PILE OF...ENERGY...SITTING OVER THE SRN PLAINS EVENTUALLY
PUSHES ENEWD INTO THE OH/TN VALLEYS ON THU NGT AND FRI. ON THU
MORNING THE GFS AND ECM ARE IN DECENT AGREEMENT ON THE POSITION OF
THIS CUTOFF LOW. BUT THAT DOESN'T LAST LONG. THE ECM INVENTS A
VIGOROUS WAVE IN THE NRN STREAM TO DROP THROUGH THE GREAT LAKES
AND PUSH THE LOW TOWARD THE SE COAST BY SAT EVE. WHILE THE GFS...
SORT KICKS THE CAN...ERR LOW...DOWN THE ROAD. LAGGING BEHIND ABOUT 
24 HRS. MY CRYSTAL BALL IS IN THE SHOP FOR REPAIRS...BUT RECENT STUDIES
HAVE SHOWN THAT THE ECM VERIFIES A BIT BETTER...SO I HAVE SHOWN A
DECREASING POP ON SAT AND DRY ON SUN. MORE GOOD NEWS...TEMPS FOR
FRI-SUN WILL DROP TO ONLY 5-8 DEGREES ABOVE NORMAL INSTEAD OF THE
CURRENT 15-20 DEGREES ABOVE NORMAL. WELL THAT'S ALL THE METEOROLOGY
MY LITTLE BRAIN CAN MUSTER AT THIS EARLY HOUR. CIAO.
