Odd Weather for the Thanksgiving Holiday in St. Louis

I was startled in the early morning hours, today, by a loud crack of thunder.  For late November, it's a rather abnormal occurrence.  That's not all.  We had a strong squall line storm sweep through Monday night, following a day that reached a high near 75°, and tonight they're predicting almost the same thing, except, with lower temperatures.  As a matter of fact, as I write this(4:23pm CT), there are supercell storms currently tracking NE out of Western Missouri, with tornado warnings!  
I find this to be worthy of a blog entry, as it is quite astounding.  I imagine, someday, it'll be fun to look back and see what wild weather conditions we had for Thanksgiving 2010.

...STRONG TO SEVERE STORMS TONIGHT WITH LOCALLY HEAVY RAINFALL...
...WINTRY PRECIPITATION EXPECTED FOR THANKSGIVING DAY...

A STRONG STORM SYSTEM CENTERED OVER THE NORTHERN PLAINS WILL MAKE
ITS PRESENCE KNOWN OVER OUR REGION OVER THE NEXT COUPLE OF DAYS.

RICH MOISTURE FROM THE GULF OF MEXICO IS BEING TAPPED AND
OVERRUNNING COOLER AIR TO THE NORTH TO RESULT IN AMPLE CHANCES FOR
RAIN WITH IMBEDDED THUNDERSTORMS TODAY...BUT ESPECIALLY DURING THE
MORNING HOURS. SOME OF THE STRONGER STORMS THROUGH MID AFTERNOON
MAY CONTAIN SMALL HAIL.

AFTER A BRIEF BREAK DURING THE AFTERNOON HOURS...A MORE INTENSE
ROUND OF RAIN AND THUNDERSTORMS WILL FIRE UP AS A STRONG UPPER
LEVEL DISTURBANCE AND SURFACE COLD FRONT APPROACH FROM THE WEST.
RAINFALL AMOUNTS TONIGHT MAY EXCEED TWO INCHES IN SOME AREAS...
WITH THE MORE FAVORED AREAS BEING TO THE SOUTH AND EAST OF THE
SAINT LOUIS METRO AREA. THIS COULD LEAD TO SOME MINOR FLOODING.

THE THUNDERSTORMS TONIGHT...AS THEY DEVELOP AHEAD OF THE STRONG
COLD FRONT...MAY ALSO EXCEED SEVERE LIMITS WITH THE POTENTIAL FOR
LARGE HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES.

THE PRECIPITATION WILL CONTINUE DEEP INTO THANKSGIVING DAY...
ESPECIALLY FOR THE SAINT LOUIS METRO AREA...SOUTHEAST MISSOURI...
AND SOUTHWEST ILLINOIS. MUCH COLDER AIR WILL SPILL VERY RAPIDLY IN
BEHIND THE COLD FRONT AND IS EXPECTED TO CHANGE THE PRECIPITATION
OVER TO FREEZING RAIN WITH SOME SLEET AND SNOW POSSIBLE AT THE
VERY END. AT THIS TIME...ONLY A VERY LIGHT GLAZING IS EXPECTED
PRIMARILY ON UNTREATED ROAD SURFACES AS TEMPERATURES HOVER JUST
BELOW FREEZING AND WITH GROUND TEMPERATURES BEING SOMEWHAT WARMER
FROM THE RECENT MILD SPELL OVER THE PAST FEW WEEKS.
