Area forecast discussion, Jul 6, 5:25 PM CST, 1 hour 5 minutes before
Area Forecast Discussion National Weather Service Norman OK 625 PM CDT Fri Jul 6 2018 .DISCUSSION... Aviation discussion for the 00 UTC TAFs is below. && .AVIATION... Overall, VFR conditions are expected to continue. ISO-NUM SHRA/TSRA will affect many sites before 02 UTC; thus, went with VCTS/VCSH with TEMPOs across several TAF sites. Gusty variable winds as well as brief MVFR or lower conditions are possible with any SHRA/TSRA. Chances of TSRA/SHRA remain too low to mention after 02 UTC. A few locations where TSRA/SHRA has already occurred may experience MVFR or lower conditions 06-15 UTC. Did not mention at any site due to low confidence of occurrence, though KCSM may have slightly higher chances of occurrence compared to other TAF sites. MBS && .PREV DISCUSSION... /issued 321 PM CDT Fri Jul 6 2018/ DISCUSSION... Determining which days have the highest probabilities for scattered showers/storms is the primary forecast issue through the forecast period. Scattered to numerous thunderstorms are ongoing across western Oklahoma and adjacent parts of north Texas this afternoon. Similar to yesterday, heavy rainfall will be the primary hazard. A secondary hazard will be damaging wind gusts with any stronger, collapsing cores. Expect most of the convection to dissipate this evening with the loss of daytime heating. For Saturday, lower precipitable water values are forecast to advect from the northeast with east-northeasterly mean 1000-500 mb flow. This will place the highest precipitable water values across west central and southern Oklahoma and adjacent parts of north Texas. This is where the chance of showers/storms were confined for Saturday. The relatively low values should prevent much convection on Sunday--except for the southeast Oklahoma. By Monday, higher precipitable water values--potentially near 2.0"-- are forecast to advect back into southeastern/southern Oklahoma with southeasterly mean 1000-500 mb flow. This will be coincident with lowered heights/a weakness in the ridge across the Southern Plains as the mid-level ridge splits with two localized maxima. As a result, there will be an increasing chance of showers/storms, especially across southern/eastern Oklahoma and adjacent parts of north Texas. There is still uncertainty on how far northwest convection may occur, but there is a low chance at least to I-44. A low chance of showers/storms should persist through the end of the forecast period. Temperatures should also remain in check near seasonal averages. Mahale && .OUN WATCHES/WARNINGS/ADVISORIES... OK...None. TX...None. && 23/17
