735 FXUS64 KTSA 011817 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 1217 PM CST Sun Nov 1 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1213 PM CST Sun Nov 1 2026 - High shower and thunderstorm chances return Monday into Tuesday, with potential for severe weather and locally heavy rain. - Temperatures closer to seasonal average mid to late week behind early week system. && .SHORT TERM... (Through tonight) Issued at 1152 AM CST Sun Nov 1 2026 Cloudy and dreary conditions this morning will gradually improve into the afternoon, with some breaks in the clouds across eastern Oklahoma noted on current satellite imagery. With some breaks, temperatures should rise into the low to mid 70s by later this afternoon, with dry conditions persisting through the rest of the day. Southerly surface winds will begin to pick up some overnight tonight in response to a developing surface low deepening over the High Plains. This will keep fog chances minimal tonight and confined to the highly sheltered valley locations. Overnight lows will also stay well above average for early November, generally in the 60s areawide. Any precipitation should stay west of the local region through tonight. Bowlan && .LONG TERM... (Tomorrow through Sunday) Issued at 1152 AM CST Sun Nov 1 2026 The main impact through the extended forecast period continues to be a threat for severe weather along with heavy rainfall Monday into Tuesday. A bit of a complicated scenario looks to unfold on Monday across eastern Oklahoma in terms of the severe weather threat across the area. A potent upper low will move through the Intermountain West today and eject out into the Plains through the day Monday. At the same time, this upper low will link up with a subtropical jet and moisture plume streaming northeastward out of the eastern Pacific and into Southern and Central Plains. recent guidance and model trends don`t phase these two systems very well, with the subtropical system progressing out ahead of the main wave into eastern Oklahoma by Monday late morning or early afternoon. Deepening tropical moisture and favorable jet location over the region provides a pretty good signal for scattered to widespread elevated thunderstorm development within this leading wave from late Monday morning into the afternoon hours, primarily along and west of Highway 75 in northeast Oklahoma. As mentioned, most of this activity will likely be elevated, which will limit the severe threat, though some stronger storms could have some gusty winds or small hail through the afternoon. Instability continues to be pretty limited, so the hail threat will stay minimal through the period. How this activity evolves will play a big role in what and where the biggest severe threat will be during the evening and overnight as the main wave and associated cold front/dryline move through the area. If more widespread early day convection develops and lingers through the afternoon, that will limit the severe threat across parts of eastern Oklahoma for later in the day Monday. The primary forcing associated with the stronger upper low will overtake the surface cold front by late afternoon or early evening Monday from western to central Oklahoma. Increasing coverage of thunderstorms is expected as this occurs, likely growing upscale into a QLCS as it approaches eastern Oklahoma by mid to late evening. The severe threat again will be highly conditional on the activity earlier in the day. Where there is less coverage early in the day, the greater the severe threat through the evening. Meager, but sufficient instability combined with strong deep layer shear will support organized updrafts capable of damaging wind gusts along with some tornado potential, as low level shear increases through the evening. Large hail seems to be less of a threat given the forecast profiles and expected linear storm mode. The line of storms will track eastward overnight through early morning Tuesday. Instability looks to weaken after midnight as the line moves east, likely signaling a slight downtrend as storms approach western Arkansas. Low level shear will remain strong however, so some isolated severe and tornado potential will continue into those areas as well. In addition to the severe threat, heavy rainfall and flash flooding could be a concern with the tropical moisture in place. The greatest area of concern looks to be northeast Oklahoma where multiple round of convection are possible. Rain rates of one to two inches per hour will be common in any thunderstorms which could affect more flood prone locations such as urban corridors or low lying areas near small creeks or streams. Of secondary concern on Monday will be strong wind gusts during the day as the pressure gradient responds to the deepening surface low lifting into the Central Plains. Winds gusts of 30 to 40mph will be common and a wind advisory could potentially be needed for parts of the area, but will hold off on issuance for now. The cold frontal passage on Tuesday will usher in cooler and breezy conditions in its wake. Temperatures will trend closer to normal ranges through the rest of the of the forecast period, though likely still above normal for most of the area. Still, some cooler mornings and drier air will dominate through the work week. A quick moving, weakening wave will move through the area on Thursday. This could bring a few light showers to the area, but dry air will keep chances minimal with this system. Another system could affect the area toward the latter half of next weekend. Bowlan && .AVIATION... (18Z TAFS) Issued at 1213 PM CST Sun Nov 1 2026 Low clouds have been slow to lift but recent observations suggest the trend has begun with expectations of a rise into MVFR and eventually VFR levels for most sites this afternoon. Low clouds likely redevelop overnight especially across western AR where forecast of low MVFR levels could trend lower with later forecasts. MVFR ceilings and gusty winds appear are likely to develop across portions of E OK Monday morning. Any precip chances by the end of this forecast period will be confined to areas northwest of Interstate 44. && .PRELIMINARY POINT TEMPS/POPS...
