Area forecast discussion, May 26, 11:57 AM CST, 1 hour 28 minutes before
Area Forecast Discussion National Weather Service Norman OK 1257 PM CDT THU MAY 26 2016 .AVIATION... Strong to severe thunderstorms have developed over the past hour, especially across northern Oklahoma and southern Kansas. Storms should continue to form near a dryline in the eastern Texas panhandle this afternoon. If storms continue to form, 18z taf tempo groups may be a little late with storms impacting terminal sites this afternoon and evening. Severe storms may impact all terminal sites, especially across western Oklahoma. MVFR to IFR conditions are likely with strong storms today. Most of the convection may move east of all terminal sites by 7-9z with mainly MVFR conditions prevailing. && .PREV DISCUSSION... /issued 622 AM CDT THU MAY 26 2016/ DISCUSSION... The 12Z aviation discussion follows.... AVIATION... There is quite a variety of ceiling heights and visibilities this morning across Oklahoma and north Texas. The general trend between 12Z and 15Z will be toward higher ceilings and better visibilities. However, thunderstorms are expected to form and/or spread north across Oklahoma late this morning into the afternoon. While there is substantial uncertainty regarding timing/location of these storms, probabilities are high enough to warrant TEMPO groups for TSRA at several sites from late morning into mid- afternoon. Additional storms are expected to form later in the afternoon and overnight. The current forecast places most of the evening/overnight TSRA southeast of a line from KSPS to KPVJ to KSNL. Stratus and BR are expected yet again overnight into tomorrow morning across much of Oklahoma and north Texas. CmS PREV DISCUSSION... /issued 410 AM CDT THU MAY 26 2016/ DISCUSSION... Warm/hot and humid weather will continue through Sunday, followed by slightly cooler weather early next week. Strong to severe thunderstorms are expected again today into tonight as a couple of upper-level disturbances arrive from the west, and interact with very unstable conditions over the southern Plains. A few showers/storms, currently over central Texas, may reach southern parts of our forecast area early this morning. More widespread showers and storms are expected to develop around noon as upper-level support arrives and weakens an already relatively weak capping inversion. As the day progresses, the greatest rain chances will shift to the southeast. The main area of rain/storms will continue to shift slowly southeast into southeastern Oklahoma tonight into Friday. While storms will probably be much less numerous farther west, there will still be some risk of severe storms over our entire forecast area on Friday. Heavy rain will be possible Friday in our far southeast counties, as the second upper-level wave passes over the region. The exact location of heavy rainfall will depend on the location of low- level focusing mechanisms, and currently the best estimate is roughly the southeastern quarter or so of Oklahoma. Saturday will be relatively quiet, but rain and thunderstorms will likely return to the region on Sunday. At this point, rain chances look relatively high from Sunday through Thursday of next week. While widespread heavy rainfall appears unlikely, locally heavy rain will be a possibility through this period. There is some significant difference of opinion between the medium-range models next week, so the risk of severe weather is difficult to determine at this time. && .PRELIMINARY POINT TEMPS/POPS...
