LONG TERM...MONDAY THROUGH THURSDAY...
AFTER A DRY MONDAY AND TUESDAY UNDER HIGH PRESSURE...ANOTHER UPPER
TROUGH IS SLATED FOR LATE TUESDAY NIGHT INTO WEDNESDAY. TEMPERATURES
LOOK WARM ENOUGH FOR MAINLY RAIN EXCEPT POSSIBLY IN THE NORTH
WEDNESDAY MORNING BEFORE TEMPERATURES WARM UP...AND AGAIN WEDNESDAY
NIGHT AFTER THE COLD FRONT MOVES IN. ONE ITEM TO WATCH CAREFULLY
WILL BE AN UPPER LOW THAT IS FORECAST TO BECOME CUT OFF LATE TUESDAY
OVER THE SOUTHERN ROCKIES. THE LONGER RANGE MODELS ARE IN GOOD
AGREEMENT IN TAKING THE LOW SOUTHWARD INTO MEXICO WHILE STILL
KEEPING IT PHASED WITH THE NORTHERN STREAM TROUGH OVER THE PLAINS.
THE NORTHERN TROUGH THEN PROGRESSES EASTWARD AND LETS GO OF THE LOW
AS IT CONTINUES TO MEANDER OVER MEXICO. NOT TOTALLY SOLD ON THIS
SOLUTION...BUT FOR NOW ITS POSSIBLE EFFECT ON CENTRAL IL LOOKS TO BE
AFTER THIS FORECAST PERIOD.

Interesting 0z GFS. Low gets to the OV and closes off. While still over the OV northern energy comes back south and phases with the closed low.

Boy that looks like it has the potential to be an awfully juicy storm. There has been a storm system for the past two weekends now, I get a feeling that this one will make it three in a row and could be the strongest of the three. Now only if we can get some cold air in place.

i am really liking the potential with this system....hoping that they are still planning the winter weather flight to collect data...waiting for updates on the flight plans for the weekend...that should really help to clear up what happens with the ULL

This system looks to have potential for our area. Will have to monitor it closely.

12Z GFS. . .

I read somewhere that the Day 8 GFS painted a picture similar to that of last February's blizzard. I'm not a guy for the model runs that you guys find, but if someone could post that, that'd be awesome.

Unless, of course, I'm quoting the very same models I'm referencing.

Yea looks juicy but that looks like lots of rain?

It's time for some snow for Missouri. Seems as if lately others are stating to get in on the fun except our state. Let's go. My totals so far are around 2 inches.

Sure, right now it could be rain. My point is that I feel that there is a possible significant system in the works for someone in the midwest. Lot's will change with the models as this thing gets under a week. Who knows, next weekend could bring severe weather for all I know. It's fun to watch though.
