From the ABC 33/40 weather blog this morning:

"NEXT WEEK: Sure looks like a significant severe weather event is ahead, initially west of Alabama Tuesday, then moving into the Deep South by Tuesday night and Wednesday. Way too early to be specific on the threat, but all of the players are on the field. Best hope for us is for the band of storms to come through during the pre-dawn hours Wednesday when the air tends to be more stable, but I get the idea it might be an event mainly during the daytime Wednesday. See the Weather Xtreme video for details."

I can't read models, so for those that can, what's your take on this?

BMX mentioned this system yesterday.  Plenty of moisture for this system to work with.

I'm sick of spring...I'm sick of having allergies....I'm sick of having rain every other day. I want the sun to shine and no more severe weather. When is this pattern going to change?

I have to agree! Our grass is knee high.. We haven't been able to mow once this year, it's been so wet :/ 2 acres of knee high grass is gonna be fun trying to mow, if it ever dries up enough to mow...

HUN hinted in a recent AFD that they are leaning towards the EURO.  

A long way to go with this one.  Should be fun to watch.

Isn't that the truth...it will take a week of sun to dry it up enough to mow. Doesn't look like that's happening for a while. This weather is seriously messing my schedules up. Its baseball season for us and at the rate we are going we'll be playing until November.LOL! Did you have much damage last night? Blytheville was hit pretty hard but we escaped it out here.

Still far out there, but a very large warm sector with widespread 60-70 Td's from the Ohio Valley south to the coast.  I know things will change, but taking a quick look at hodo's and once again they are long and clockwise curving with impressive 0-3KM helicity values.

One mitigating factor in the long run for this type of setup may be a limited to non existent EML. Given the prolonged period of direct flow out of the gulf its possible we may just totally load the profiles with moisture and get much more of a mid summer type look versus a spring look. But Im just thinking out loud really.

EML is like the CAP right?

At this point it may take longer than a week...lol At least we didn't get much rain last night. We dodged the bullet last night. we're just a hair north of Gosnell, just barely into MO. We heard Gosnell's sirens going off in our backyard. I saw a little damage when I drove through Gosnell today, but it was minimal. We didn't have any damage, but the wind blew our satellite out of alignment.. Thought we were going to get some more rain this evening, but it stayed south of here, thankfully. Hope it's not storming Friday because that's the market set-up day and we have an open bed truck.. I don't want my stuff to get wet!

0z GFS is getting closer to showing another tornado outbreak for this time frame.

Timing will probably change, but 12z gfs has it coming through Wednesday afternoon into the evening.

BMX

THE UPPER TROF OVER THE WESTERN UNITED STATES WILL SHIFT SLOWLY EASTWARD AND BRING AND A MORE ACTIVE SOUTHWESTERLY FLOW PATTERN BACK INTO ALABAMA NEXT WEEK. GFS/ECMWF ARE IN FAIRLY CLOSE AGREEMENT IN DEVELOPING INITIAL SURFACE LOW OVER OKLAHOMA AND PULLING IT RAPIDLY NORTHEAST. THIS WILL PUSH A WEAKENING LINE OF THUNDERSTORMS TOWARDS WEST ALABAMA MONDAY NIGHT. THE SECOND SURFACE LOW WILL DEVELOP FARTHER SOUTH AND BRING INCREASING CHANCES OF SEVERE STORMS TO ALABAMA ON WEDNESDAY. THE FRONT SHOULD CLEAR OUT THE RAIN BY THURSDAY.

yes, and here it is.....

THE QUASI-STATIONARY FRONT WILL LIFT NORTH A BIT FOR SUNDAY AS LOW
PRESSURE FORMS OVER THE TEXAS PANHANDLE. THIS LOW WILL TRACK ALONG
THE FRONT INTO THE MID MISSISSIPPI VALLEY MONDAY AND MONDAY NIGHT.
ANOTHER...ALMOST IDENTICAL SYSTEM WILL TAKE A SLIGHTLY MORE
SOUTHERLY TRACK FROM NORTH TEXAS THROUGH ARKANSAS INTO SOUTHERN
INDIANA TUESDAY NIGHT. BOTH WILL GIVE THE MIDSOUTH A GOOD SHOT AT
SEVERE THUNDERSTORMS...POSSIBLY ONE OR BOTH BEING SIGNIFICANT
OUTBREAKS - PARTICULARLY AS THE LLJ STRENGTHENS EACH NIGHT AND
LENGTHENS THE HODOGRAPHS. PROLONGED FETCH OF MOISTURE LADEN AIR
SHOULD BRING SUFFICIENT MOISTURE AND INSTABILITY NORTHWARD. STORM
MODE AND TIMING ARE STILL QUITE UNCERTAIN...BUT THE DYNAMICS AND
SHEAR INDICATE THE POTENTIAL FOR TWO HIGHER END EVENTS EARLY NEXT
WEEK.

The second one has all the looks of a possibly major outbreak across MS and AL. Instability is lacking on the GFS as of now, but that will likely change. Had better hope the timing changes or we may deal with a mid-night outbreak. Fun.

That is completely irresponsible of him to do at this time.  His blog post sounds too matter of fact, instead of saying it is just a possibility.

With all the heavy rains falling along the Ohio River, and across the northern-mid portions of the MS river valley.  I would a little on down the line be very concerned with river flooding for both the OH River, MS River, and some of their tributaries.
Please keep the families impacted by this year's severe weather in your thoughts and prayers.

The GFS has already been all over the place today. Lol. The 06z seems to be somewhere in the middle which is slower then the 12z by a tad, but still coming through during the afternoon and evening which will help pose a higher threat for Georgia.

It will probably end up being yet another night event so I don't get to see barely even any lightning. Not hoping for an EF5 or anything but some small hail and strong winds would be nice. It'd help get rid of all this pollen.
