Keeping the Snowy Faith Alive

More terrific news for you snow lovers hoping for a White Christmas.  Here's the breakdown of this situation:

0z Canadian: Continues to hold strong on the snowy concept, but now it appears that this would spell a major snowstorm for parts of the SE.  From hours 96-120, our system is between the borders of MS and AL heading across the central and southern portions of AL and GA at 108 toward the northern section of the SC coast.  A surge of heavier moisture also spreads over the Carolinas as the low continues to strengthen to 1001mb early Sunday.  With the already cold ground temperatures and strong cold air pushing behind this system, it can really set the stage for a truly cold and snowy Christmas later that day Saturday.  Subzero wind chills could also be an issue for folks trying to head out during the night hours.

0z UKMET:  This run of the UKMET takes our system WAY south!  At first it seemed as though it was going to follow what the Euro did, but as soon as it left Texas, the low takes a dive toward Florida.  In fact, it is sitting around 1010mb and west of Tampa Bay at 120hrs.  From there, the low curves up but stays well east of Cape Hatteras.

0z Euro:  This run was no different than its 12z or the Canadian for that matter in terms of what plays out.  Starting at hr. 24, the shortwave comes in strong toward the Southern California area (deja vu, anyone?).  It is a bit south of where the 12z had at 36hrs.  The track of the low continues to be further south as we approach the 48hr. period to the point where it is closed (also continues at 54hrs.).  Our low then positions itself in NW AZ at 60 while still being closed and quite potent as well.  Suddenly, as it approaches NM, the low is directly in the center of the state at 72hrs., but suddenly opens up a little, only to be closed again six hours later.  By the time we reach the 84hr., the low is now in West Texas with an inverted trough through OK and KS while precipitation is falling heavily.  During the 90hr., the closed low's precipitation is about to reach Memphis and eighteen hours later at 114...the phase takes place at the right time and area (so it appears).  By 120, a 1012mb low sits in the Panhandle of FL and suddenly BOMBS in SE GA with snow taking over Western Carolina, VA, and even in ATL!  QPF totals are very impressive (nearly an inch in the CLT region), and temperatures are shaping up to not be an issue whatsoever.  The low by then has become 1000mb near Charleston with snow falling in most of the Carolinas and E GA.

So there you have it.  This has been three times now that the runs (especially the Euro) have shown a significant winter event to occur for our area.  Will it hold for Tuesday and Wednesday?  Time will tale the tell.  My confidence level at this point has raised to 35/65 or 40/60 (Give or take 5.  Left side for yay; right for nay).  Is this all a dream!?  Nah couldn't be...or could it??????  See you on the next update.
