Honestly this is kind of a boredom post, but I decided to take a look at the GFS models for this weekend and look at the thunderstorm chance. Right now, because of how far out this event is the SPC has not issued any convective outlooks. However, they do think that more than one severe event is possible later in the week, and that the real determining factor is moisture. I will try to keep an eye on the models through the week, partly because I have nothing else to do, and partly because I am interested in how this pans out! Here is a bit of info from the SPC and some graphics from the GFS model. I will be holding out for that moisture needed!
DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0352 AM CDT MON MAR 15 2010
VALID 181200Z - 231200Z
...POTENTIAL TOO LOW TO DELINEATE A SEVERE THREAT AREA...
THE LARGE-SCALE PATTERN EVOLUTION THROUGH THE COMING WEEK STILL
APPEARS UNLIKELY TO ALLOW GULF OF MEXICO BOUNDARY LAYER MODIFICATION
SUPPORTIVE OF A SUBSTANTIVE INLAND RETURN FLOW THROUGH AT LEAST LATE
NEXT WEEKEND. THIS SHOULD GREATLY LIMIT CONVECTIVE POTENTIAL
THROUGH THE PERIOD. HOWEVER...MEDIUM RANGE GUIDANCE CONTINUES TO
INDICATE THAT SIGNIFICANT AMPLIFICATION OF THE UPPER FLOW NEAR THE
PACIFIC COAST LATE THIS WEEK COULD YIELD A STRONG/INTENSIFYING SHORT
WAVE IMPULSE THAT DIGS THROUGH THE SOUTH CENTRAL PLAINS...BEFORE
SWEEPING EASTWARD INTO THE SOUTHEASTERN U.S. NEXT WEEKEND.
CONSIDERABLE SPREAD DOES EXIST AMONG THE MODELS AND MODEL ENSEMBLES
CONCERNING THIS FEATURE. BUT IT IS WITHIN THE REALM OF POSSIBLE
SOLUTIONS THAT STRONG LIFT AND DIFFERENTIAL THERMAL ADVECTION...IN
THE PRESENCE OF AT LEAST WEAK MOISTENING AND STRENGTHENING DEEP
LAYER SHEAR...COULD OCCUR ACROSS PARTS OF THE SOUTH CENTRAL PLAINS
INTO THE LOWER MISSISSIPPI VALLEY/CENTRAL GULF COAST REGION LATE
FRIDAY THROUGH SATURDAY. SO ...THE RISK FOR SEVERE STORMS MAY NOT
BE COMPLETELY NEGLIGIBLE.
..KERR.. 03/15/2010
So, I will keep an eye on this, but as of now it doesn't look like an "oh my gosh"
scenario. Keep checking back for updates!
UPDATE:

THIS HAZARDOUS WEATHER OUTLOOK IS FOR MIDDLE TENNESSEE.
.DAY ONE...TODAY AND TONIGHT
NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
A STRONG COLD FRONT IS EXPECTED TO PASS THROUGH MIDDLE TENNESSEE
SATURDAY OR SATURDAY EVENING. IT IS POSSIBLE THAT SEVERE STORMS MAY
OCCUR WITH THIS SYSTEM.
