Tornado Watch issued for eastern ND!

A tornado watch has been issued for eastern ND and extreme northwest MN for this afternoon/evening until 11:00 pm CDT ahead of a strong cold front surging southeastward towards the Red River Valley.  Towering cumulus can be seen on satellite along the front from southeast Manitoba southwestward into central ND.  These towers could develop into supercells over the next few hours.
The 2100 UTC RUC analysis shows CAPE values of 4000+ J/kg from southwest Manitoba into eastern North Dakota, with 0-1 km EHI values of 3+.  Mixing in the lower atmosphere has been strong so far today, reducing the low-level shear values and increasing LCLs.  However, after around 7:00 pm CDT, as the lower atmosphere decouples, a strong low-level jet will develop and dewpoints will increase to around 70F.  If storms initiate, and remain discrete into the evening, then isolated tornadoes will be possible!  Stay tuned for updates.

Some-thing sure has been building up fast in NE North Dakota on the reflectivity scans...

Anyone checked out the killer gravity waves on satellite over Ontario/MN?

Very cool looking.

Reed! you are the man!!

Tornado Watch issued for eastern ND! Comment Posted By Strike | August 26, 2007 @ 5:46 PM #

Well, looks to me like that line is starting to uncork in central ND.

Tornado Watch issued for eastern ND! Comment Posted By Reed | August 26, 2007 @ 5:50 PM #

Nice Andrew!!

I saw the most incredible gravity waves on April 5, 2003 during the morning on top of the moisture inversion. I'll try and find pictures.

That cell in northeast ND is exploding!

Boom goes the dynamite!

Tornado Watch issued for eastern ND! Comment Posted By Andrew | August 26, 2007 @ 5:53 PM #

Reed what do you see for tomorrow for the eastern part of MN? does it look like early supers out west and then a line forming?

Just curious, going to be outdoors all day tomorrow with kids...

The rotation over Portage La Prarie right now is nuts.. I'm watching the radar animation and the whole thing is spinning.. yet the low is showing as North east of winnipeg.. you'd think that'd be the center but watching the radar it's west haha.

Tornado Watch issued for eastern ND! Comment Posted By tim jacobs | August 26, 2007 @ 6:02 PM #

has anybody been checking the storms growing to west???

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 6:02 PM #

They finally got rid of the clear-air VCPs out of KMVX... 'bout time!

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:03 PM #

Now if we can just convince Environment Canada to give us Velocity Doppler.. it's like the stone age up here ):

what's the new warning grid it's pink and says EWW.

Tornado Watch issued for eastern ND! Comment Posted By PB | August 26, 2007 @ 6:09 PM #

Agree, GRlevel3 is cooool.
Joe pointed us to Puerto Rico radar when Dean was steaming past and we got to watch the eye for a while on cr248.
I got 8 days left to watch.
Certainly would be nice to have something like that for Canada.
Nice how few resources it uses.
Which radar site to park on this eve?

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 6:10 PM #

I think KMVX near Grand Forks might be the one at the moment PB

Tornado Watch issued for eastern ND! Comment Posted By Andrew | August 26, 2007 @ 6:11 PM #

PB I might sit on Grand Forks tonight. The storms in NE North Dakota look like they're struggling a bit for now, but the one further south closer to Jamestown is kinda cooking.

Joe- JINX. lol.

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 6:15 PM #

Great minds stink alike!

Tornado Watch issued for eastern ND! Comment Posted By MynameisBen | August 26, 2007 @ 6:19 PM #

Joe...in the last blog...you asked why Gr3 doesn't incorporate watch boxes...even though...they do incorporate warnings. There are place files, for those...i have a place file to show Meso discussions, Watches, and a place file that outlines my KILX warning area.

I will try and post the Meso discussion and Watch place files when i get home, although it may be hard to do from there..

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 6:21 PM #

Thanks, Big Ben. Place files is something that is still on my to-do list to explore... I'm aware of them but haven't got around to loading any yet. My e is joesurfer@usa.com if you have any juicy ones

Tim Jacobs,

"has anybody been checking the storms growing to west???"

Depending on who you talk to in this country, "west" can mean anything from Ohio to California... which state are ya looking at?

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:33 PM #

I expect the severe t-storm warnings to start popping up along the MB border here any minute.

Tornado Watch issued for eastern ND! Comment Posted By Brady MN | August 26, 2007 @ 6:37 PM #

Huh! There aint a cloud in the sky now!
humidity is slowly goin up! 57% now!

Tornado Watch issued for eastern ND! Comment Posted By Strike | August 26, 2007 @ 6:39 PM #

Look at the last 2 frames from the Woodlands radar.

Looks like north of Nopiming prov park is getting something.

Part of the same line? maybe it will pop all the way across soon. Too bad chasing anything that far east sucks cuz of the forest.

Maybe still time to catch it southeast?

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:42 PM #

Static radar.. east of Winnipeg's developing. Massive storm along the ND/MB/MN Border right now. Expecting a warning on there within this cycle probably.

Tornado Watch issued for eastern ND! Comment Posted By Strike | August 26, 2007 @ 6:46 PM #

Tim: I've been watching that one to the east for 10 or so minutes. Getting tall real fast. I'll give it 10 more minutes and if it continues to grow I'm gone. Head staight out to Dugald. Good viewing for quite a while if I remember correctly.

Tornado Watch issued for eastern ND! Comment Posted By Reed | August 26, 2007 @ 6:46 PM #

IT'S HAPPENING!

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 6:48 PM #

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:48 PM #

Yup. There's a massive cell right NNW of Grand Forks right now.. wouldn't be surprised if we get a warning on it shortly. Haha Reed.. Bout time too.. I've EARNED my storms putting up with beautiful weather for 2 weeks in a row.

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:49 PM #

Tornado Watch issued for eastern ND! Comment Posted By Tim | August 26, 2007 @ 6:50 PM #

The cell that just missed Pembina crossing into MB is looking AMAZING as well. I wouldn't be surprised if a tornado warning was issued soon with that one as well. Running out of chase-able terrain up there!

Tornado Watch issued for eastern ND! Comment Posted By Reed | August 26, 2007 @ 7:07 PM #

Actually it turned right and is heading straight for Pembina!

Tornado Watch issued for eastern ND! Comment Posted By Reed | August 26, 2007 @ 7:09 PM #

Second cell down has a massive hook developing and an intense couplet!

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 7:10 PM #

I thought I read somewhere that storms that turn right tend to get nasty...

Tornado Watch issued for eastern ND! Comment Posted By Joe Surfer | August 26, 2007 @ 7:11 PM #

good eyes Reed! Look out Edinberg, Crystal, Hoople?

Tornado Watch issued for eastern ND! Comment Posted By Reed | August 26, 2007 @ 7:12 PM #

Yeah with the LLJ kicking in both of these cells have the chance to put down a big tornado...~90/70 in their environment!!!!

Tornado Watch issued for eastern ND! Comment Posted By brandon | August 26, 2007 @ 7:16 PM #

Tornado Watch issued for eastern ND! Comment Posted By brandon | August 26, 2007 @ 7:22 PM #

id give anything to be near that supercell west of grafton, ND...i bet that thing is beautifully structured, because its radar signature is perfect!....DAMN!!

We're keeping our eye on the radar here in Grand Forks, ND. We could really use some rain, but without high winds and hail.

Tornado Watch issued for eastern ND! Comment Posted By Caro | August 26, 2007 @ 7:28 PM #
