358 FXUS64 KTSA 011726 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 1126 AM CST Thu Jan 1 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1055 AM CST Thu Jan 1 2026 - Above average temperatures are expected over the next 7 days. - Low to medium rain chances develop tonight into Friday morning, but most rain totals are expected to remain light. Overall, dry conditions are likely to persist into next week. - Fire weather potential likely increases by early next week with breezy afternoon winds, very warm temperatures, and low relative humidity values. && .SHORT TERM... (Through Friday) Issued at 1055 AM CST Thu Jan 1 2026 A weak surface boundary has settled over northeast Oklahoma this morning, with northerly surface winds noted behind the boundary. Slightly cooler temps are expected this afternoon to the north of the boundary while temperatures south of the boundary will climb into the upper 60s. The boundary will wash out more or less later this afternoon as southerly winds return in response to surface pressure falls occurring over the High Plains. Mid and high cloud cover will also increase this afternoon ahead of modest mid level disturbance. This quick moving shortwave will track across eastern Oklahoma and western Arkansas late tonight into Friday morning, in tandem with a weak surface low which will ride along the Red River. This area of vorticity should be enough to spawn a zone of light showers across eastern Oklahoma late tonight along a weak mid-level deformation zone as surface moisture increases slightly...generally south of I- 44. Forecast soundings show a relatively dry layer close to the surface, which will likely eat in to rain totals as evaporation takes place. Rain totals are generally forecast to remain around a tenth of an inch or less. Some areas could see upwards of a quarter inch where some of the heavier showers can develop. Skies will clear from west to east throughout the morning and early afternoon hours Friday as the rain pushes east rather quickly with the shortwave. The early day cloud cover, especially across the north, along with northerly winds filling in behind the exiting system will keep forecast highs slightly cooler, but still above normal, on Friday. && .LONG TERM... (Friday Night through Thursday) Issued at 1055 AM CST Thu Jan 1 2026 A secondary push of cooler air will arrive Friday night into Saturday as a surface high drop southward out of the Northern Plains. Some areas of low clouds could also filter in, particularly across the eastern half of the forecast area, Saturday morning as another mid level wave passes over the region. These clouds could be stubborn to erode throughout the day and the result will be cooler temperatures, closer to normal across the north, on Saturday. Temperatures begin to rebound on Sunday and will rise well above normal again on Monday as southerly winds return and mid-level heights rise as ridging builds back over the Southern Plains. Fire weather concerns will increase somewhat each afternoon, as winds become gusty. A dry frontal passage is expected on Tuesday, which will knock temperatures back a few degrees for the middle part of the week, but temps remain well above normal. Rain chances could increase over the last part of the work week as a western CONUS trough takes shape and potentially lifts over the region on Thursday, shunting the ridge to the east. Differences remain among various deterministic and ensemble guidance on the track and strength of this system, but an uptick in PoPs is noted in this forecast across eastern portions of the forecast area next Thursday. Bowlan && .AVIATION... (18Z TAFS) Issued at 1126 AM CST Thu Jan 1 2026 We`ll see increasing mid and high cloud this afternoon and tonight ahead of a fast-moving upper storm system. By late tonight into Friday morning, cigs will settle down to around 10kft with some spotty showers around. With low to medium precip chances in the forecast, elected to use prob30s to convey most likely time windows at the various sites. Statistical guidance suggested best chance for vsbys lower than VFR was from TUL/RVS east into NW AR at FYV/ROG/XNA where an MVFR vsby was included in prob30 group. Aside from this, VFR conditions should prevail at all sites through the period with light winds. Lacy && .PRELIMINARY POINT TEMPS/POPS...
