At this point a torrential downpour is needed to refill lakes and streams. Anonymous. 03-24-2015, 06:19 PM Really depends on where storms fire and how matured they are when they hit OKC. But yes, severe storms is how many Oklahoma lakes and ponds fill up. venture 03-24-2015, 07:03 PM One storm finally starting to pull up a bit in SE OK, northeast of McAlester. http://www.weatherspotlight.com/screencap/2015-03/24-3.png SomeGuy 03-24-2015, 09:19 PM I didn't catch KFOR but David Payne is being very level headed about tomorrow, I figured they'd take the opportunity to hype the thing up. Mike Morgan was definitely hyping the heck out of the storm saying that there will be large hail,, damaging winds and multiple tornadoes up to E F2. Mike Morgan needs to relax a bit sometimes imo. venture 03-24-2015, 09:41 PM Couple of SVR warnings out in SE OK, so today is the new record for latest severe warning for the state. Anonymous. 03-24-2015, 09:49 PM I am starting to grow a little more concerned with the trend of delayed cold front tomorrow evening. Earlier runs showed the front blasting through and basically cutting any surface action the cells have early on. Could get some pretty big HP supercells on the dryline that shove east, also training could occur along storm's outflow boundaries somewhere from WC OK to C OK depending how far back the storms fire. Like V mentioned, if wind shear profiles were more favorable, the setup would be ripe for larger tornados. Could have some flash flooding where cells train. Right now I wouldn't rule out early spin ups, especially if dryline cells can stay discrete and not muddy each other up. Also this will increase hail sizes. venture 03-25-2015, 12:52 AM Interesting shift in the outlook tonight. Enhanced Risk now from Lawton to Pauls Valley north to the entire Metro area and then north of I-40 to the east and due north to the KS border. Slight risk for the rest of the area in Southern Oklahoma. Highest tornado risk at 5% over NE OK, 2% tornado area over the Metro. Hail risk area at 30% for the ENH RISK area. Sig Hail / Hatched area from the Metro back tot he Northeast. http://www.spc.noaa.gov/products/outlook/day1otlk_1200.gif?1427262722178 http://www.spc.noaa.gov/products/outlook/day1probotlk_1200_hail.gif?1427262733055 DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 1244 AM CDT WED MAR 25 2015 VALID 251200Z - 261200Z ...THERE IS AN ENH RISK OF SVR TSTMS LATE THIS AFTERNOON AND EVENING ACROSS PARTS OF NORTH CENTRAL AND NORTHEAST OKLAHOMA...ADJACENT SOUTHEAST KANSAS...SOUTHWEST MISSOURI AND NORTHWEST ARKANSAS... ...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE ENH RISK...ACROSS PARTS OF THE SOUTH CENTRAL PLAINS INTO THE OZARK PLATEAU... ...THERE IS A MRGL RISK OF SVR TSTMS ACROSS SURROUNDING AREAS OF THE CENTRAL AND SOUTHERN PLAINS EAST NORTHEASTWARD INTO PARTS OF THE LOWER OHIO VALLEY... ...SUMMARY... SEVERE THUNDERSTORMS...MAINLY CAPABLE OF PRODUCING LARGE HAIL AND LOCALLY DAMAGING WIND GUSTS...ARE EXPECTED ACROSS PARTS OF THE SOUTH CENTRAL PLAINS INTO THE OZARK PLATEAU LATE THIS AFTERNOON AND EVENING. ...SYNOPSIS... SIGNIFICANT AMPLIFICATION IS ONGOING WITHIN A BRANCH OF MID-LATITUDE WESTERLIES ACROSS THE EASTERN PACIFIC INTO WESTERN NORTH AMERICA. AS LARGE-SCALE MID/UPPER RIDGING CONTINUES TO BUILD NEAR THE PACIFIC COAST DURING THIS PERIOD...MODELS INDICATE THAT LARGE-SCALE TROUGHING WILL BEGIN TO EVOLVE DOWNSTREAM...EAST OF THE ROCKIES...THROUGH THE VICINITY OF THE APPALACHIANS. WITHIN THIS LATTER REGIME...ONE NOTABLE SHORT WAVE IMPULSE IS FORECAST TO PIVOT RAPIDLY NORTHEASTWARD...FROM THE OHIO VALLEY THROUGH THE ST. LAWRENCE VALLEY BY LATE TONIGHT. AN ASSOCIATED SURFACE LOW MAY CONSOLIDATE WITH ANOTHER LOW OVER THE GREAT LAKES REGION...BEFORE CONTINUING INTO QUEBEC LATE IN THE PERIOD...WITH A TRAILING COLD FRONT ADVANCING SOUTHEASTWARD ACROSS THE CENTRAL UNITED STATES. INITIALLY STALLED OVER PARTS OF THE LOWER OHIO VALLEY/OZARK PLATEAU AND CENTRAL PLAINS...MODELS SUGGEST THAT THE SOUTHWESTERN FLANK OF THIS FRONT WILL BEGIN A MORE RAPID SOUTHWARD SURGE...IN RESPONSE TO ANOTHER SIGNIFICANT SHORT WAVE IMPULSE DIGGING SOUTHEAST OF THE CENTRAL ROCKIES THROUGH MUCH OF THE SOUTH CENTRAL PLAINS BY 12Z THURSDAY. THIS MAY BE ACCOMPANIED BY WIDESPREAD CONVECTIVE DEVELOPMENT...AND THE RISK FOR SEVERE STORMS. ...SOUTH CENTRAL PLAINS/OZARK PLATEAU INTO LOWER OHIO VALLEY... SOME BOUNDARY LAYER MOISTENING CONTINUES ALONG AND SOUTH OF THE FRONT...BUT A SUBSTANTIVE RETURN FLOW OF MOISTURE OFF THE GULF OF MEXICO STILL APPEARS UNLIKELY DURING THIS PERIOD. MODEL SURFACE DEW POINT FORECASTS FOR THIS AFTERNOON MAY STILL BE AT LEAST A BIT TOO HIGH. HOWEVER...NORTHEASTWARD ADVECTION OF WARM ELEVATED MIXED LAYER AIR IS EXPECTED TO AGAIN CONTRIBUTE TO VERY STEEP MID-LEVEL LAPSE RATES BY THIS AFTERNOON. THIS PROBABLY WILL SUPPORT SIZABLE CAPE /PERHAPS AT OR ABOVE 2000 J PER KG/ WITHIN AT LEAST A NARROW CORRIDOR ALONG THE FRONTAL ZONE. IN THE PRESENCE OF STRONG SHEAR BENEATH 40-50 KT WESTERLY 500 MB FLOW...CONDITIONS SHOULD BECOME CONDUCIVE TO THE DEVELOPMENT OF SEVERE STORMS FOR AT LEAST A PERIOD LATE THIS AFTERNOON INTO EARLY EVENING. MODELS SUGGEST THAT FORCING FOR ASCENT ASSOCIATED WITH LOW-LEVEL WARM ADVECTION MAY SUPPORT A RAPID INCREASE IN SEVERE STORM DEVELOPMENT BY 20-22Z NEAR THE CENTRAL AND EASTERN KANSAS/OKLAHOMA BORDER AREA. THIS MAY INITIALLY INCLUDE DISCRETE STORMS...BEFORE GROWING UPSCALE...WHICH SHOULD TEND TO TRACK EASTWARD ALONG THE FRONT INTO THE OZARK PLATEAU. ADDITIONAL SEVERE STORMS MAY FORM SHORTLY THEREAFTER ACROSS PARTS OF WEST CENTRAL OKLAHOMA. IT APPEARS THAT THIS LATTER ACTIVITY WILL OCCUR JUST AHEAD OF THE SOUTHWARD SURGING COLD FRONT...AND STRONGER STORMS PROBABLY WILL BE CAPABLE OF PRODUCING LARGE HAIL AND LOCALLY STRONG WIND GUSTS. AS LARGE-SCALE FORCING SUPPORTS INCREASINGLY WIDESPREAD THUNDERSTORM ACTIVITY THROUGH MUCH OF THE INSTABILITY AXIS...WHILE THE SURFACE COLD FRONT BEGINS TO SURGE SOUTHWARD AND TENDS TO UNDERCUT CONVECTION...IT REMAINS UNCLEAR AT THE PRESENT TIME HOW LONG THE SEVERE WEATHER POTENTIAL WILL CONTINUE INTO THE EVENING HOURS. ..KERR/MOSIER.. 03/25/2015 Bobby821 03-25-2015, 06:25 AM Will someone please tell channel 4 that we are NOT in a Moderate risk for storms today. Sheesh how can you equate an Enhanced risk with a Moderate. it is no wonder people are so ill informed on weather and do not take it serious when they should with this kind of forecasting. Soonerman12 03-25-2015, 07:33 AM Bobby, the rating system is all kinds of jacked up. The only thing that matters is we are at risk for ALL modes of severe weather this afternoon and evening. Honestly, who cares the risk. People just need to remember to be aware. Being a person that chases storms I've seen this wayyy to many times. There will be days that are only forecasted as "slight" and we have a outbreak and days it is moderate and not a rain drop. Quit listening to local mets and pay attention to Venture, anon, myself ect. We don't use risk just give facts of what the satellite says and what chasers physically are seeing in the field. Soonerman12 03-25-2015, 07:40 AM Looks like we could see a triple point set up in central OK today. Everyone please remember that severe weather is likely. People need to keep aware especially when storms first fire up, that'll be most likely time frame when discrete supercells will form. The more likely area to see this weather will be from a line from OKC to Tulsa to Joplin and NW Arkansas.

THESE COULD YIELD A COUPLE TORNADOES IN ADDITION TO VERY LARGE HAIL AND DMGG WIND. AS THE COLD FRONT ACCELERATES SEWD THIS EVE AND OVERNIGHT...EXPECT RESULTING SQUALL LINE/QLCS TO BECOME INCREASINGLY UNDERCUT IN THE PLNS...WITH A DIMINISHING THOUGH STILL NON-ZERO THREAT FOR LOCALLY DMGG WIND AND HAIL SWD INTO PARTS OF TX.

Come on man. Don't put the bad juju out there like that. Anonymous. 03-25-2015, 08:59 AM 60F+ Dewpoints already pouring back into the state this morning. If you noticed the haze, you know it is severe weather time in OK. Hail size could be pretty damaging with isolated supercells. Also I want to emphasize the flash flood threat, especially around C OK. We could have one of those boundaries that fires off cell after cell over the same area until the cold front really blasts by. First severe risk for OKC this year, and we start with a Moderate. Soonerman12 03-25-2015, 09:02 AM Bobby... The NWS Storm Prediction Center has now upgraded OKC to Tulsa to Joplin in the "moderate" risk area you referred to earlier... So maybe morgan was right lol Anyways, people in these areas PAY ATTENTION the SPC doesn't just issue this for no reason. This likely will become rapidly severe supercells this afternoon that WILL have a chance to produce tornadoes. Like I said earlier, triple point looks to set up in Central/East OK. I would say persons in OKC to Stillwater to Tulsa have the highest risk. I live in Tulsa, looks like it could be a long chase night.

I'm having a hard time with really believing either of them.. I don't think the HRRR is positioned correctly with storms around Tulsa that early and I don't agree with NAM not really having much kick started by then. The only thing I do agree with is the positioning of the storms firing off on the NAM I just believe it will be blown up by then. Who knows, either way it'll be there no matter what. venture 03-25-2015, 10:02 AM Venture... I'm having a hard time with really believing either of them..

The only thing I do agree with is the positioning of the storms firing off on the NAM I just believe it will be blown up by then. Who knows, either way it'll be there no matter what. HRRR is just firing the dryline, whereas the NAM waits for the front. Both are very possible today, we'll just have to watch. Main thing is Tulsa and NE OK won't get dryline play, so position of the front will be key for them up there. venture 03-25-2015, 10:07 AM Moisture flooding back in pretty good...we'll need to see how much of this mixes out with daytime heating. http://www.mesonet.org/data/public/mesonet/maps/realtime/current.TDEW.grad.png venture 03-25-2015, 10:51 AM 14Z HRRR initiation of storms along the dryline at 4PM. http://climate.cod.edu/data/forecast/HRRR/14/OKC/hrrrOKC_prec_radar_007.gif venture 03-25-2015, 10:54 AM 2-5KM Updraft Helicity, showing potential rotation in storms later...VERY large hail possible with strongly rotating storms. 5PM http://climate.cod.edu/data/forecast/HRRR/14/OKC/hrrrOKC_con_uphly_008.gif 6PM http://climate.cod.edu/data/forecast/HRRR/14/OKC/hrrrOKC_con_uphly_009.gif Anonymous. 03-25-2015, 10:59 AM MD out for S KS. Most of SW, C, and S OK are under sunshine, while N and NE parts of state are under a cloudy haze. This could have an affect on fuel for the storms. Easy180 03-25-2015, 11:05 AM So are most models predicting that cars in garages by 5:00 in OKC should remain dent free? SoonerBeerMan 03-25-2015, 11:11 AM Does the sun shining here in C OK and S/SW OK start to eat away at the available moisture in the air, or does the heating add more fuel to future storm development? Anonymous. 03-25-2015, 11:29 AM Heating is better for storm development, but yes the higher heat generally eats away at moisture, but when you have this kind of GOM moisture spilling into the area in March, it is more than enough. This setup is more conducive for late April into May. Areas seeing sunshine are in the 60F dewpoint @ 75F+ air and areas under cloud cover are at the same dewpoint, but @ 60-65F air. http://www.mesonet.org/data/public/noaa/sat/maps/realtime/latest.goes_east.visible.png?1427300735569 venture 03-25-2015, 11:36 AM MDT Risk expanded slightly more West and south to include all counties of the Metro. Tornado risk increased to 5% for the entire area. SPC discussion... ACROSS CENTRAL/SWRN OK...LAST SEVERAL RUNS OF THE NCEP HRRR ARE CONSISTENT IN DEVELOPING SUPERCELLS NEAR THE SURFACE LOW AND ALONG THE DRYLINE BY MID TO LATE AFTN. THESE STORMS WOULD POSE A RISK FOR VERY LARGE HAIL AND DAMAGING GUSTS FOR A FEW HOURS BEFORE BEING UNDERCUT BY THE ADVANCING COLD FRONT. ALTHOUGH A TORNADO OR TWO WILL BE POSSIBLE...LARGE SFC TEMP-DEW POINT SPREADS AND RESULTANT HIGH LCL HEIGHTS WILL TEND TO MITIGATE POTENTIAL FOR PERSISTENT LOW-LEVEL ROTATION. WITH TIME...STORMS SHOULD DEVELOP A MORE LINEAR STRUCTURE ALONG THE COLD FRONT ACROSS ERN OK.
