Area forecast discussion, May 19, 2:07 AM CDT, 14 minutes before
Area Forecast Discussion National Weather Service Norman OK 207 AM CDT Thu May 19 2022 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today and tonight) Issued at 203 AM CDT Thu May 19 2022 Ongoing convection is expected to continue to move eastward into parts of north central Oklahoma by early this morning. Severe winds and large hail are expected to be the main threats. Trended down on temperatures this afternoon owing to outflow from the overnight/early morning convection. Nevertheless, another day of unseasonably warm temperatures is in store with temperatures in the low 90s for most of the area, and into the 100s across portions of western north Texas. Southerly surface winds will recover this afternoon to about 15-25 mph across the area. Dry RH values in western north Texas in addition to the gusty winds will foster near critical fire conditions. For this evening, winds will continue to be breezy through the overnight hours. This warm advection will keep lows into the mid 70s for most of the area and in the upper 60s for northwest Oklahoma. && .LONG TERM... (Friday through Wednesday) Issued at 203 AM CDT Thu May 19 2022 On Friday, unseasonably warm temperatures will continue across the area, where most places will get into the 90s and into the 100s in western north Texas. Southerly winds will drive mid 60s dewpoints into central Oklahoma Friday afternoon ahead of an advancing cold front. Convergence along this boundary could foster scattered strong to marginally severe thunderstorms along and east of I-44 Friday afternoon and evening. Sufficient instability and effective shear could help storms organize some, with the main hazards being large hail and damaging winds. The aforementioned cold front will cool temperatures this weekend and early next week down significantly from what we have had the last several weeks. Temperatures are expected to be in the mid 70s on Saturday and into the upper 60s on Sunday and Monday, before gradually warming back up into the 80s by the end of the week. Medium range models are in good agreement with a mid-level trough across the Western CONUS early next week. This trough will bring widespread precipitation chances starting Monday early morning and going into Wednesday morning. As of right now, thunderstorms could be strong and are not expected to be severe. Flooding is expected to be the main hazard. Subsequent forecasts will continue to monitor these trends. && .AVIATION... (06Z TAFS) Issued at 1118 PM CDT Wed May 18 2022 Mostly VFR conditions are expected throughout the TAF period. An MCS is moving through parts of the OK/TX Panhandle and are expected to traverse northwestern and north central OK overnight. Could see storms impact KWWR, KPNC, and KSWO into the early morning. Otherwise, outflow from the aforementioned storms are expected to alter the winds slightly out of the north before recovering late morning and becoming southerly. LLWS could impact KLAW and KSPS overnight and into the morning. && .PRELIMINARY POINT TEMPS/POPS... Oklahoma City OK 93 75 90 63 / 0 0 20 20 Hobart OK 99 74 95 61 / 0 0 0 10 Wichita Falls TX 101 75 101 69 / 10 0 20 20 Gage OK 97 61 81 50 / 0 10 0 0 Ponca City OK 92 74 85 57 / 20 10 20 40 Durant OK 91 71 90 72 / 0 0 10 20 && .OUN WATCHES/WARNINGS/ADVISORIES...
