000 FXUS64 KOUN 240139 AFDOUN Area Forecast Discussion National Weather Service Norman OK 839 PM CDT Sun Sep 23 2018 .UPDATE... Increased the coverage of cloud cover through 12Z. Otherwise, no significant changes were made to the forecast. && .DISCUSSION... Stratus continues to slowly expand westward this evening within weak east to east-southeasterly low-level flow. The potential for dense fog should be limited by the stratus; however, some patchy fog will be possible--especially near the 100th meridian and northwest Oklahoma, where skies should remain clear for a longer period of time. Drizzle and/or light rain also remain possible across southeast/south central Oklahoma with weak isentropic ascent and greater forecast depth of low-level saturation. Mahale && .PREV DISCUSSION... /issued 603 PM CDT Sun Sep 23 2018/ DISCUSSION... 00Z TAF discussion. AVIATION... Will continue with MVFR ceilings overspreading all sites this evening and then lowering to IFR overnight with some fog around as well. Have kept most sites at 4 miles or higher with exception of WWR where took down to 2 miles late. Moisture remains rather shallow and should see a bit more sun even into I-44 corridor by Monday afternoon with VFR conditions. PREV DISCUSSION... /issued 405 PM CDT Sun Sep 23 2018/ DISCUSSION... Stratus will likely spread back north and west again overnight, with some potential for fog in the far west where it has cleared off this afternoon. Otherwise the southeast part of the area remains near the northwest periphery of the precipitation area - most of the precipitation chances are to the southeast, but close enough for the mention of some drizzle or perhaps light rain southeast. The higher rain chances come in late Tuesday into Wednesday as a front moves into the area and a mid-level shortwave moves across the Plains. Split the difference a little bit between the rainy GFS and the dry ECMWF for Wednesday night due to the uncertainty on the timing of the wave exiting the area. && .PRELIMINARY POINT TEMPS/POPS...
