Hi Mike! Haven't seen you in a while. Hope you're in a safe place!

The front storm approaching the metro is going up and down. The hook get tightened up then fall apart. Got to watch it carefully. The tornado threat just increased for the next few hours. We still got storms out behind the front storm.

They all seem to really be worried about tomorrow - they're comparing it to the Alabama outbreaks. It gets old hearing "perfect storm" with every severe outbreak though.

You're right. Each outbreak are unique.

Large tornado reported right now at Highway 9 and I-35. In the path are OU, NWS, Airport, and the town.

You OK?

Yes, thanks. The first wave brought some rain but not any hail and then it skirted on down to Norman and I got interested in watching that instead of checking back in, here. Plus, the dog was freaked out and I was peeling her off the ceiling.

This second round has had hard rain and about four pea sized pieces of hail but that's about it. My weather station is not giving my rain readings for some reason, but the regular guage says almost an inch and a half. It came right over us but we can see the light green that follows the storm, right now.

I've been flipping channels between all the Big 3 and from what I've seen, they are all equal. They look at damages, radars, and live videos. It just depend on the moment you flip to a channel and what you catch them showing.

There are Tornado Warnings issued in SW Oklahoma right now and the track of that storm is gunning for the metro area. It will arrive in about two hours if it holds together. That storm seem to be the most impressive out of all today.

I haven't seen a single photo in the 40 minutes I've been watching, or the video of the tornado in Norman that they are showing on whatever station Gary England is on. (I think that's what I'm listening to?) There was one time they briefly went to someone in the field and they showed footage of some random clouds for about a minute. Other than that it's constant radar stuff.

And this KOCO station is spending every second on the storm around Hobart and Altus, which is somewhat strange as people down there don't even get KOCO, and are watching their own KSWO.

Edit: They're showing Norman footage, finally!

That is very frightening. It is almost like they are saying that tomorrow will be far worse than May 3rd. I'm actually thinking right now if I can convince my mother to drive away from the state or stay put in this house and potentially be killed. Closest shelter is Del City High School, but I've read months ago that shelters like that are misleading sense of security due to concrete and steel overhead the gym area capable of skyrocketing deaths. My home is a 5th Wheel. Mom's home wouldn't stand a chance, I believe.

I didn't confuse it with anything, I just repeated the wording verbatim from the AP story. But you're right - it seems they confused it. It's even at the Washington Post site now. I suppose the gist of it is the same regardless.


As states across the middle of the country prepared for the worst, storms were already kicking off in Norman, Okla., where a twister whizzed by the nation’s tornado forecasting headquarters but caused little damage.

It was only the second time in U.S. history that the Storm Prediction Center issued a high-risk warning more than 24 hours in advance, said Russ Schneider, director of the center, which is part of the National Weather Service. The first time was in April 2006, when nearly 100 tornadoes tore across the southeastern U.S., killing a dozen people and damaging more than 1,000 homes in Tennessee.

Venture, I've never asked...all I know is your name is Kevin, but where do you work? Are you a a meteorologist? What a fascinating business (especially this time of year!)...

Update on today's situation...

06Z GFS
Very Unstable atmosphere will develop through the day. CAPE will get to around 3000 j/kg from Wichita Falls to Ponca City. Wind profiles and shear values are favorable for tornado formation later today and will increase after dark. Initial storm formation is forecast to start in SW OK between 4 and 7PM and then expand throughout Central OK during the overnight hours until about 7AM when most activity should be pushing into SE OK.

06Z NAM
Much the same story as with the GFS. Very to highly unstable atmosphere today with CAPE values 3000-4000 j/kg over much of Central OK from border to border. EHI values will be favorable from Pauls Valley to the North. LCL values forecast to be a tad high through early evening which could restrict some tornado development. Storm formation timeline is a bit different than GFS. Initial activity expected in North Central OK by 7PM and then developing down through SW OK by 4AM. Impacts on Central OK will be from 4AM through 10AM on Sunday.

HRRR short term forecast has things dry through 5PM...so this is looking like a late show. New SPC outlook in next post.

nws storm prediction center norman ok
0745 am cdt sat apr 14 2012

valid 141300z - 151200z

...there is a high risk of svr tstms later this afternoon into

ok...

...there is a mdt risk of svr tstms surrounding the high risk...from
sw ok to far ne neb and wrn ia...

nw tx to wrn neb...ia...and mo...

...tornado outbreak expected late this afternoon into tonight from
central/ern neb swd across ks to central ok...with the potential for
long-track/damaging tornadoes...

...synopsis...
A closed low over nw az this morning will progress ewd/enewd to the
high plains by this evening while evolving into more of an open
wave...and then continue into the central plains by the end of the
period. An associated surface cyclone will deepen and move newd
from ern co this afternoon to ne neb/se sd by 12z sunday. S of the
cyclone...a well-defined dryline is expected to reside from central
ks swd into wrn ok and nw tx by this evening...while a warm front
moves nwd from ks this morning to central/ern neb by late afternoon.
A moist and unstable warm sector will cover neb/ks/ok/n tx to the e
of the dryline and s of the warm front. The primary locations for
severe storm development today will be near the surface low moving
into neb...and the dryline trailing swd into ks/ok.

...central plains through tonight...
The forecast reasoning remains largely unchanged from the past few
days. In the wake of morning waa storms across ne ok/se ks/sw
mo...low-level moisture will surge nwd across ks to s central/se neb
by mid-late afternoon. Daytime heating invof the dryline and
boundary layer dewpoints ranging from the low 60s in neb to the
mid-upper 60s in central ok will contribute to afternoon mlcape
values of 2000-3500 j/kg. Meanwhile... Deep-layer vertical shear
will be quite supportive of supercells in the unstable warm
sector...with effective bulk shear of 50-70 kt across almost the
entire warm sector. The degree of low-level moisture and an
expected increase in low-level shear later this afternoon into early
tonight will result in an environment clearly into the parameter
space associated with previous strong-violent and long-track tornado
episodes.

the primary question this outlook will be storm coverage along the
dryline this evening in ks/ok. The convective schemes in the
operational models vary with storm initiation signals...while
several of the convection-allowing models generate widely scattered
dryline supercells in the 22-01z time frame. Forecast
soundings...modified for expected afternoon temperatures along the
dryline...show deep mixed layer and little or no convective
inhibition. Plus...a well-defined band of low-level ascent is
expected along the dryline...which suggests at least
widely-scattered thunderstorm development across the ks/ok portion
of the dryline is entirely plausible. Farther n...potentially more
concentrated storm development is expected near the surface low and
nw edge of the unstable warm sector in neb /within the left exit
region of the jet aloft/. all factors favor discrete convective
modes through early tonight...and though storms could be widely
spaced...they will be capable of producing long paths of very large
hail and damaging tornadoes through at least 06z.

late tonight...the midlevel trough will fully emerge over the plains
and the pacific cold front will overtake the dryline...potentially
supporting more extensive squall line development near or after 06z.
Damaging winds will be more of a threat with the more linear and
widespread convection late tonight...given a continuation of
surface-based instability and 60-70 kt flow in the lowest few
thousand feet agl.

Here is the morning Upper Air Sounding from Norman.

Moderately unstable this morning already with no CAP. We'll see CAP increase a bit through the day. One of the more concerning part is the STM value for later today - that is Storm Motion. Right now it is good at NE @ ~30 to 34 mph. However late it is expected to increase to 40 to 50 mph making advanced warning times very limited.

For a more detailed break down, go to http://www.weatherspotlight.com and click on Soundings. You'll see a chart with values and their relative meanings and can compare to the soundings.

AHA after I posted that, I found the answer - SRH: "Storm-Relative Helicity," referring to a characteristic of a storm to rotate...

For any other "self-educating" weather junkies out there, there's a really nice top-level glossary of storm/meteorological terminology available at http://www.pilotfriend.com/pilot_resources/met/a.htm

Norman PD recommends routes for Red-White game traffic

Read more: http://newsok.com/norman-pd-re...1#ixzz1s1qprAwB

Norman city officials strongly suggest that persons planning to attend the OU Red and White football game this afternoon avoid using the core-area streets, such as Berry Road, Flood Avenue (Hwy 77), and Porter (Sunnylane).

The police department recommends routes include I-35 to Hwy 9 and Sooner Road (12th Avenue).

It took me an hour and a half to go from my home near Lindsey & McGee to Sooner Mall to return a rental car and then get back home, a total round trip of about five miles.

Besides the closed roads and gawker traffic, people have apparently assumed that traffic laws/signals, especially stop signs, have no meaning at all.

If you come here, be careful and be prepared to wait.

Wow thanks for the heads up. I was actually about to walk out the door to go to the Spring Game, although maybe I should have left earlier.

Maybe it was just my bad timing, but sometime between 9:45 when I left for the mall and when I got back home, traffic just exploded. There's a lot of foot traffic too, people wandering around with cell phones taking videos, even saw one guy with an iPad "filming" a video with his girlfriend. Dads letting their kids stand in holes in the ground left by fallen trees, with the giant root ball looming above, etc.

If you can get east of Berry, you might be OK. I don't attend football games, so I don't know the usual traffic routes. Last I checked, Lindsey east bound off I-35 was closed, 24th between Brooks and Lindsey is closed. These are just routes I ran across in my usual Saturday meandering, I don't know about any others.

Shame on the city of Mustang for NOT turning on the sirens last night

Well, the supermarket is completely apocalyptic. Any new data indicating that this thing is gonna happen in central OK or will it be north?

Slayton, best I can tell is the SPC draws the "high risk" line roughly from east of Woodward-to-Weatherford, and then north of I-40. I haven't seen anything that would suggest the threat has mitigated, unfortunately. That said, it was clear earlier today that the chasers headed north to Kansas en masse, so that tells me that a good many of those folks think there's a better chance for chasing/spotting up there. I wouldn't assume anything has changed, still looks like anywhere in west-west central OK is at risk for severe weather today.

Storms beginning to fire up in far western OK where it has been clearing. More development possible through late afternoon with rapid storm movement.

Thanks, SD...was starting to think they were moving things off to the north. Where's Venture? I've tried to find his 'room' all over the net and I can't do it.
