Anonymous. 05-08-2014, 09:34 AM Back edge of these clouds are coming into Canadian county now. If we get cleared out fully here by around 11am. Could be enough heating of the recently rained on ground that we become decently unstable. Dryline/Cool front already advancing in far NW OK this morning, so the timing may be off today. I would say the further north you are, the better chance of storms this afternoon. Would love to get another solid line, the rain we get from these is our only hope this summer. SPC has highlighted the Day 4-5 timeframe in their outlook. Right now, it does look significant. catch22 05-08-2014, 10:00 AM The hype of "tornado" was hardly spot-on. The other two were stressing how this is not a tornado event. Damon even said, "It's just not that type of situation." David never veered from no tornado threat. The National Weather Service didn't think he was spot-on either, if there was a tornado in any part of the metro area - they would have issued a tornado warning. I was actually driving on I-44 right at 89th when this was going on. (Basically right in the area he said a tornado possibly was) I can confirm the power flashes, and extremely strong wind. It was actually kind of scary -- glad he was on the radio, understood exactly what he was saying. I'm not a fan of his style at all, but in the moments I needed information I got exactly what I needed listening to his broadcast. Based on evidence on the ground (power flashes in the same area), and evidence on the radar (the wind shear) -- he made the right call. Better safe than sorry. I rather him say there is the possibility of a tornado and there not be one, than him to completely dismiss it, and people be caught off guard even on an F-0. Of Sound Mind 05-08-2014, 10:06 AM I look pretty good. I'm having a fabulous hair day. Me too! (It helps that my hair is essentially a buzz cut.) PennyQuilts 05-08-2014, 10:16 AM Me too! (It helps that my hair is essentially a buzz cut.) Good day, bad day, I have a massive long hair "fro" that makes hair stylists gasp with joy or fear, depending on their level of confidence.

I'm not a fan of his style at all, but in the moments I needed information I got exactly what I needed listening to his broadcast. this. as far as i could tell, ch4 was the only station simulcasting on the radio, and driving home after the thunder game, i needed more info than a radar screen or text message warning could give me. PennyQuilts 05-08-2014, 10:39 AM I was listening to him because they had a spotter in the area where I live. I also thought it was helpful and he made it clear, throughout, that if there was a tornado, it was a very small one. Does anyone know if he panicked anyone in the area he said it was going through? I was amazed that other than power blinks and losing the television, once, we kept power. There were some big winds coming through. No particular tree damage, either. soonerguru 05-08-2014, 10:53 AM Ya, I agree - it certainly looked scary for a few minutes. A few facebook friends are reporting debris and downed limbs, so there was certainly reason for concern. I think overall Morgan was pretty accurate. I watched him last night because my DirecTV was out and my "over the air" digital signal was not allowing me to watch Damon Lane and I can't stand David Payne. I thought Morgan was very clear and fair in saying that it "could" be a tornado, showed why, and explained that it could also just be straight-line winds. He also made clear that the biggest threat even if it was a tornado would be windows being blown out, downed limbs, and a few missing shingles. Timmer, another guy whom I'm not crazy about, was clear when saying it was a wall cloud whether or not it was rotating. He did report the power flashes, but that's what spotters should do. Let's not forget that the storm did produce at least one tornado down in the Wichita Mountains, so it's not hard to imagine it spawning another F0-F1 type tornado. I've been harsh on Morgan in the past, but I thought his coverage was accurate and fair, and he didn't try to "hype it up," he just reported the conditions and what he saw on radar. venture 05-08-2014, 11:18 AM Short term models hinting at some isolated development late this afternoon in SW OK and also North Central OK. Looks like we will have full sun now for the rest of the day, so we'll see how this plays out. venture 05-08-2014, 11:36 AM Slight risk has been modified to cover the area generally along and west of I-44. ...EASTERN KS SOUTHWARD INTO WESTERN OK... WIDESPREAD SHOWERS AND THUNDERSTORMS HAVE OCCURRED OVERNIGHT ACROSS PARTS OF KS/OK AND NORTH TX...STABILIZING THE AIR MASS AND INCREASING UNCERTAINTY OF SEVERE THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON. STRONG HEATING IS LIKELY ALONG THE DRYLINE OVER EASTERN KS AND WESTERN OK TODAY YIELDING A CORRIDOR OF MODERATE CAPE AND ONLY WEAK CAP. THUNDERSTORMS MAY DEVELOP ALONG THIS AXIS BY LATE AFTERNOON AS THE SURFACE COLD FRONT MERGES WITH THE DRYLINE. THOSE STORMS THAT FORM WOULD BE IN AN ENVIRONMENT FAVORABLE FOR ROTATING UPDRAFTS AND LARGE HAIL PRODUCTION...ALTHOUGH LOW LEVEL SHEAR WILL BE RATHER WEAK. THOSE STORMS THAT FORM WILL TRACK EASTWARD INTO WESTERN MO DURING THE EVENING. zookeeper 05-08-2014, 11:53 AM Maybe I was too harsh on Mike Morgan. I honestly thought it was all hype based on what the others were saying. But, I very well could be wrong. Thanks for the posts. bchris02 05-08-2014, 12:32 PM The NWS has moved the area of highest risk to the metro and areas west of it. http://www.srh.noaa.gov/images/fxc/oun/graphicast/image6.jpg soonerguru 05-08-2014, 12:40 PM More rain would be great.

In all fairness the couple times I flipped channels he was the only one still consistently on the air and advising people. I still have a bad taste in my mouth from some of his calls last year so I guess I'll always be a bit hesitant to trust him. ou48A 05-08-2014, 03:54 PM Dallas tx- 339 pm cdt thu may 8 2014 ...a tornado warning remains in effect until 415 pm cdt for northeastern dallas county...

Northern sides about to go up right now, struggling as it trails off to the SW.

Watching TV TOR coverage in DFW is always frustrating. Sent from my iPhone using Tapatalk You are telling me (ughh!) In a meeting and had no idea this was going on. No sirens, no emails, someone just happen to have a mobile alert on their phone. Fortunately it was in NE Dallas County whereas I am in Addison. It looks like there is quite a bit of damage and flooding. Really miss OK weathermen in situations like this. PennyQuilts 05-08-2014, 04:31 PM Here's a question - I haven't checked the weather (came here, first) but my blind dog is on full alert and she hates storms. Anything starting to pop? bchris02 05-08-2014, 04:35 PM Anything going up yet for us? We had cumulus clouds most of the day, which seems to be the case on outbreak days but now it appears to be all clear. What time do you think the dryline will fire storms that couple possibly affect OKC? Anonymous. 05-08-2014, 04:48 PM CU still struggling. CAP is too strong down here still. NC OK looks like it could go any minute. But still has not. Storm firing just north of the border into KS along the same boundary. As it sits right now, I would bet on no storms firing for main body of OK this eve. EDIT: Just after posting, last scan shows storm going up SW of Ponca City. These will try and back build to the SW as the late afternoon progresses. PennyQuilts 05-08-2014, 05:08 PM Well, maybe Pearly was just nervous about an earthquake or something. Around here, it could be anything. :) OKCMallen 05-08-2014, 05:21 PM Astronomy is fascinating and it is a shame there isn't more education on it in grade schools. At night during a full moon, I suggest you do the same since you can actually stare at it. Think about how this massive sphere is rotating at the same speed as Earth and is also orbiting Earth. And if 7th grade science memory serves, the moon rotates at just the right speed in conjunction with its revolution around the earth to where we always see the SAME SIDE of the moon. woodyrr 05-08-2014, 05:42 PM My brother got to his home in Dallas. Fortunately, there were only some small tree branches down. He has power, but there is evidence it was out for a period. Love Field is about 2 miles northwest and they reported a measured wind of 70 MPH at one time. The more significant damage appears to be in the community of Highland Park to the immediate east and northeast of his house. I have been down there several times during tornado warnings and go absolutely crazy every time trying to get a handle on things as I am watching the TV coverage. I can't stand to watch the guys around here because of the way over the top exaggeration and I can't stand to watch the folks in DFW because they come across as more clueless than I am. I'm thankful for RadarScope and for the folks who post on here. ou48A 05-08-2014, 05:52 PM Wow I have relatives in Highland Park.... There are tons of big old trees that could be a big hazard in that area. woodyrr 05-08-2014, 05:54 PM Sadly, there are somewhat fewer as of today and at least one fewer BMW convertible.

Last night's storms kind of surprised me. Even though in the grand scheme of things they weren't really that severe, I had thought our severe window would be wrapping up around 10pm at the very latest. I am glad we got them though. The rain really helped, though we still need more. Lake Hefner didn't seem to benefit as much as I thought it would from last night. Dustin 05-08-2014, 11:50 PM Nothing exciting out there tonight.

I'll have the radar stream going, but won't be able to adjust it remotely. I'll be in the chat on my tablet updating as needed. mblackwell 05-09-2014, 11:44 AM Any chance that SPC moves OK into a Moderate risk for Sunday/Monday based on model trends? venture 05-09-2014, 11:52 AM Any chance that SPC moves OK into a Moderate risk for Sunday/Monday based on model trends? I think Monday is a wash out and there will be little severe weather. Sunday I think we could see a bump to moderate. Tornado threat is definitely going to be there as well as some giant hail. This is the forecast NAM sounding for Norman, and conditions will be better just a bit west. Not perfect backing of the winds at the surface, but still good shear and hodograph (the graph on the right) looks pretty good as well. Lots of instability and everything. Could be a pretty busy day. http://beta.wxcaster.com/skewts/NAM-test/060/SKT_NAM__koun.png PennyQuilts 05-09-2014, 12:05 PM I'd rather have weather on a weekend because more people have flexibility on their schedules and don't have to worry about rushing to get kids or being stuck at work.

KFOR just recently jumped on the hype train but prior to the noon weather cast they didn't even forecast this to be that significant. It could be one of our busier days of the year so far for the state. However if you look at the archive we have here (2014 Severe Weather Archive - OKCTalk (http://www.okctalk.com/showwiki.php?title=Island:37164)), there really hasn't been a big day yet at all. The 7th has been the biggest day as far as number of reports, but that was still a typical slight risk day. Models have not been handling this weekend well at all, so that would explain why some are holding back a bit. Charlie40 05-09-2014, 12:23 PM Channel 5's Brad Sowder has a post on Channel 5's website saying Significant Severe Weather expected for Sunday. ou48A 05-09-2014, 12:34 PM KFOR TV CH 4 OKC indicates that there is a moderate risk on Sunday in north central OK, central OK and south central OK.. They indicated that storms should approach the OKC area by about 7 pm and they will include the risk of tornadoes. venture 05-09-2014, 12:40 PM Day 2 updated to include NC OK now, which goes along with the morning models. ...SRN AND CNTRL PLAINS/MID MS VALLEY...

ADDITIONAL STORMS MAY DEVELOP EWD ACROSS CNTRL AND ERN MO LATE SATURDAY AFTERNOON. CONVECTIVE COVERAGE SHOULD MARKEDLY INCREASE DURING THE EVENING AND OVERNIGHT PERIOD FROM NE KS...SE NEB EWD ACROSS IA AND NRN MO DUE TO STRONG WARM ADVECTION ASSOCIATED WITH A STRENGTHENING LOW-LEVEL JET. FORECAST SOUNDINGS AT 00Z/SUN FOR KANSAS CITY SHOW A DEEP MOIST LAYER BELOW 850 MB WITH STEEP LAPSE RATES IN THE LOW TO MID-LEVELS. THIS SHOULD CONTRIBUTE TO MODERATE INSTABILITY WITH MLCAPE ESTIMATED IN THE 2000 TO 2500 J/KG RANGE. THE SOUNDING ALSO SHOWS VEERING WINDS WITH HEIGHT BELOW 700 MB AND STRONG SPEED SHEAR IN THE MID-LEVELS RESULTING IN ABOUT 40 TO 45 KT OF 0-6 KM SHEAR. THIS ALONG WITH THE STEEP MID-LEVEL LAPSE RATES SHOULD MAKE CONDITIONS FAVORABLE FOR SUPERCELLS WITH LARGE HAIL. ISOLATED HAIL GREATER THAN 2 INCHES MAY OCCUR WITH ANY DOMINANT SUPERCELL CLOSE TO THE MAX IN INSTABILITY. HAVE ADDED A SIGNIFICANT HAIL PROBABILITY CONTOUR ACROSS ERN KS AND WRN MO WHERE THE POTENTIAL FOR VERY LARGE HAIL APPEARS TO BE GREATEST. IN ADDITION...0-3 KM LAPSE RATES APPROACHING 8.5 C/KM SHOULD BE SUPPORTIVE OF A WIND DAMAGE THREAT.

Last year things really didn't get going until the May 18-20th outbreak but the last two weeks of May were among the most violent in state history.

From the language I've been hearing I am guess Sunday is expected to be that kind of day? I don't think ANYONE has been comparing Sunday to any of the big days last year. And most violent in state history? It was barely Top 10 in tornado product last year. Everything is relative though. 2012 we had the busiest April tornado wise on record, but it was confined to mostly NW OK. For them it was a busy year, for us in Central OK it was mostly ho-hum. At some point it is almost to where you are wanting to hear it is going to be a major outbreak to feed your paranoia. We are well below the levels of last year right now, at some point things average out. No sense in worrying about where a day is going to rank or compare. By outbreak standards, if there is even such a standard, May 20th had 15 tornadoes...for the entire state. That's not really a lot. It is just notable because of the EF5 that hit a populated area. Do you hear people talk about the October 1998 outbreak anymore? Not really. That had 26 tornadoes. Sunday is a bit elevated in concern for severe weather. Immediately trying to draw comparisons to events of the past though is just foolish. Anonymous. 05-09-2014, 01:17 PM Legit gulf moisture is just basking over the entire main body of TX. 70+ DPs galore. If this rich stuff can stream up here tomorrow and tomorrow night, we could have a good shot at tornadoes (Sunday). I do have some doubts, especially with the little swing by system tomorrow that will be moving up the stalled boundary playing games on our Sunday setup. bchris, nearly all of your posts in weather threads are asking us to confirm hype scenarios. Just take the information and learn about it, comparisons and hype is for the local mets. If hype without much science is what you want, you are in the wrong thread. The most hype you will get here is bread and milk warnings in the winter. soonerguru 05-09-2014, 01:17 PM Venture, I'll be in Norman Saturday afternoon.

Are we talking about garden variety t-storms or the possibility of something more significant? Hail, wind, and obviously heavy rain. Tornado is low, but not zero like any severe storm. Norman is probably far enough south to not warrant any panic, just keep radar app on tap to check out in the afternoon. |
