Northern Dallas County in north central Texas... * Until 230 AM CDT. * At 1129 PM CDT, Doppler radar and automated rain gauges indicated slow moving thunderstorms producing very heavy rain across Northern Dallas County including White Rock Lake. Between 2 and 4 inches of rain have fallen. Additional rainfall amounts of 1 to 3 inches are possible. Flash flooding is ongoing or expected to begin shortly. HAZARD...Flash flooding caused by thunderstorms. SOURCE...Radar and automated gauges. IMPACT...Flooding of small creeks and streams, urban areas, highways, streets, and underpasses as well as other poor drainage and low lying areas. * Some locations that will experience flash flooding include... Dallas, Garland, Irving, Coppell, Farmers Branch, University Park, Sachse, Addison and Buckingham. Interstate 635, the Dallas North Tollway, Interstate 35E, and Highway 75 may all experience urban flooding. PRECAUTIONARY/PREPAREDNESS ACTIONS... Be aware of your surroundings and do not drive on flooded roads. Be especially cautious at night when it is harder to recognize the dangers of flooding. && LAT...LON 3298 9661 3280 9661 3280 9673 3285 9676 3286 9696 3299 9694 FLASH FLOOD...RADAR AND GAUGE INDICATED $$ Dunn Link to comment Share on other sites More sharing options...
Powerball Posted June 6, 2021 Share Posted June 6, 2021 Mesoscale Precipitation Discussion 0280 NWS Weather Prediction Center College Park MD 1128 PM EDT Sat Jun 05 2021 Areas affected...Northeast Texas...Far Southern Oklahoma Concerning...Heavy rainfall...Flash flooding possible Valid 060328Z - 060700Z Summary...Isolated flash flooding may continue across portions of North Texas and far southern Oklahoma through the early overnight hours with rainfall rates as high as 2-3"/hr. Discussion...Deep convection is expanding across portions of northeastern Texas late this evening, amid a highly favorable mesoscale environment for heavy rainfall (as well as relatively slow storm motions). SPC mesoscale analysis indicates MLCAPE of 1000-1500 J/kg, PWATS of 1.7-1.8 inches (above the 90th percentile for FWD), and effective bulk shear of near 20 kts. In addition, the placement of a synoptic scale upper-level low over central TX is providing a fair amount of divergence/diffluence aloft. These factors, along with a weak low-level jet (20 kts) and modest 925-850 mb moisture transport, should continue to foster upscale growth of convection over the next several hours. The just in 00z HREF suite also suggests that convection will be able to continue to proliferate through 06z. The probability matched mean (PMM) QPF suggests an additional 2-3" is possible over a fairly broad area over northeastern Dallas and points northeastward (toward far southern Oklahoma). The current convective trends bear this out, as radar and satellite imagery depict continued storm mergers and outflow enhanced convergence over an analyzed region of deep moisture convergence. 00z HREF 40-km neighborhood probabilities suggest a 30% chance of 3-inch exceedance over the next several hours. This 3-inch exceedance has already been realized just north of Dallas (near Allen, TX), according to dual-pol radar estimates via KFWS (as well as MRMS 3-hr QPF through 03z) which depicts an area where 5+ inches of rain has already fallen. Hydrologically, much of the surrounding area is already relatively saturated, as NASA SPoRT-LIS soil moisture percentiles average above the 70th percentile. Given these latest convective trends, the 00z CAM output, and antecedent soil conditions, flash flooding will continue to be possible through 07z. Of particular concern is the prospect of convection backward-propagating farther into the Dallas-Fort Worth metro area, given the relatively slow storm motions and high rainfall rates.

Quincy Posted June 7, 2021 Share Posted June 7, 2021 I’m in Stratford, OK which is about an hour SE of Norman. It’s been raining here almost every day for the past 3+ weeks. Yards are flooded. Grass is growing out of control. Reminds me of 2015, except even later in the spring. It’s crazy that it’s been so much hotter in the northern states lately than we’ve been at all this entire spring! I only had two chase days in Oklahoma all year too. Definitely a weird year and an odd pattern. Link to comment Share on other sites More sharing options...
janetjanet998 Posted June 7, 2021 Author Share Posted June 7, 2021 another wet day in this area and another MCS over DFW pattern looks drier after this however but models hinting at tropical system 8-10 days out in the western gulf “This is the highest all of the lakes have been all year,” said Greg Waller, a service coordination hydrologist at the Weather Service. “We’re in a persistent rain pattern, and we’re to a point that a thunderstorm that produces an inch of rain is producing flooding.” He said he has been referring to the recent rainfall as “May 2015-lite.’” During the 2015 storms, the rainfall was greater and the affected areas were larger. “We’re getting enough breaks for some of the water to drain downstream,” he said. https://www.dallasnews.com/news/weather/2021/06/02/persistent-tstorms-showers-across-north-texas-prompt-flood-warnings-lake-closures/ Link to comment Share on other sites More sharing options...
