Area forecast discussion, Jun 6, 2:05 PM CST, 1 hour 18 minutes before
Area Forecast Discussion National Weather Service Norman OK 305 PM CDT Sun Jun 6 2021 ...New LONG TERM... .SHORT TERM... (This evening through Monday) Issued at 222 PM CDT Sun Jun 6 2021 Complex scenario will continue tonight into Monday as upper low fills and opens ups as it moves ever so slowly northeast. Had a few storms this morning and storms have begun to develop this afternoon. Expect to see this activity continue through the afternoon hours across parts of central and south/southeastern Oklahoma. Quite a bit of instability, but not much shear. Storms will likely be pulse-type producing some marginally severe hail and perhaps some gusty wind as well as heavy rainfall. Expect a lull in the activity late this afternoon into the early/mid evening. Later this evening, anticipate additional shower/thunderstorm development to occur with main areas being across parts of western/southwestern Oklahoma into north Texas as well as to our west across west Texas. Activity over our area, possible developing in the late evening hours, expected to be in response to minor disturbance rotating around western side of upper low coinciding with developing llj. Although instability will be decreasing due to loss of daytime insolation, bulk shear will increase, which should allow at least some potential for strong to severe storms with this activity. Slow movement and high PWATs will also result in higher rainfall rates and some localized flooding. Meanwhile, expect to see convection develop portions of eastern New Mexico as minor shortwave moves east out of the southern Rockies. Several models including HRRR, GFS as well as others support some of the higher terrain convection making it far enough east to congeal with the activity already in Oklahoma/north Texas. This complex then moves/develops east and southeast. Exact location and strength of this complex is still in question, but most likely area/s would be southern Oklahoma southward into north Texas. Expect to see some lingering shower/thunderstorm activity across parts of south/southeast Oklahoma Monday morning. Although a downward trend in coverage is anticipated, additional activity will remain possible during the day as upper low continues to translate northeast away from the area. && .LONG TERM... (Monday night through next Saturday) Issued at 305 PM CDT Sun Jun 6 2021 By Monday evening through the overnight hours, expecting the upper low to be centered over the U.S. Midwest, with the opened trough in place across the Southern Plains. A southerly low-level jet will be developing across northeast Texas through southwestern Oklahoma transporting gulf moisture and increasing the low-level shear. With a mid-level vort max in the upper wave above the low-level jet, would expect the vertical ascent to be sufficient enough to develop some convection, as mid-level cooling southwest of the upper low should maintain an unstable environment aloft. As a result, will maintain chance POPs in the grids Monday evening and overnight across southeast and southcentral Oklahoma, to slight chances across central Oklahoma. Models differ with the degree of instability aloft, with both NAM & GFS stronger with up to 2000 J/kg of MUCAPE in our POP area, while the ECMWF is a bit weaker up to 1000 J/kg. Of course the convection expected during the short term of the forecast may also affect the degree of instability late Monday, which also adds to the uncertainty. At least based on the more aggressive NAM, cannot completely rule out a few strong to marginally severe storms. Ongoing and additional flooding may also be affecting southern portions of our CWA due to excessive rainfall. Although both NAM & Canadian NH models project a bullseye of over two inches of preciptable water across northeast Texas through Arkansas, southeast Oklahoma will be approaching two inches Monday night. At least for now, a marginal potential for flash flooding across southcentral through southeast Oklahoma will be the primary hazard to deal with for Monday night. With an upper ridge starting to build in from the west, expecting the trough to move off to the east with the storm POPs decreasing by Tuesday afternoon. As the upper ridge continues to build, our entire forecast area should remain dry through the remainder of the week. However, unseasonably hot and muggy summerlike conditions will be the main issues. Breezy south winds will continue to advect hot and humid air. The moisture advection will create a dryline across the Southern High Plains, with the most abundant moisture of muggy 70-75 degree dewpoints across the central one third of Oklahoma. Although slightly drier, much of western Oklahoma and western north Texas should still see triple digit high temperatures on Wednesday & Thursday afternoons, while most areas west of I-35 will feel triple digit heat index values between 100-105 degrees. We should see a little bit of relief from the heat beginning Friday across northern Oklahoma and by Saturday across the remainder of our area. On Friday, an upper wave digging across the U.S. Northern Plains will be pushing a surface low across the Central Plains with a dry cold front moving into northwest Oklahoma, then across most of our area overnight. The slightly cooler air should bring temperatures back down close to seasonably average into the weekend. A short-wave ripple in our upper ridge could bring our next chance for storms across northwest Oklahoma on Sunday. && .AVIATION... (18Z TAFS) Issued at 1206 PM CDT Sun Jun 6 2021 Abundant moisture will allow some MVFR ceilings to continue this afternoon with some improvement this evening. There will also be a chance for thunderstorm development across parts of central Oklahoma this afternoon with a better chance overnight into Monday morning across the western half of Oklahoma southward into north Texas. Expect to see MVFR ceilings redevelop late tonight and continue through end of forecast period. Mainly south/southeast winds with daytime speeds around 12kts with lighter winds overnight. && .UPPER AIR...

The primary severe weather hazards will be hail up to the size of half dollars and wind gusts of 60 to 70 mph. In addition, locally heavy rainfall is possible. Thunderstorms may cause localized flooding with high rainfall rates and slow movement. .SPOTTER AND EMERGENCY MANAGEMENT STATEMENT... Storm spotter groups and emergency management personnel should prepare for severe weather operations through tonight. .DAYS TWO THROUGH SEVEN...Monday through Saturday... .Thunderstorms... Scattered thunderstorms will continue and redevelop on Monday with thunderstorm chances continuing through Tuesday. The potential for severe weather will be low on Monday and Tuesday.
