FXUS64 KOUN 120615 AFDOUN Area Forecast Discussion National Weather Service Norman OK 1215 AM CST Fri Dec 12 2025 ...New NEAR TERM, SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1215 AM CST Fri Dec 12 2025 - Temperatures plunge into the 30s on Sunday; otherwise near or above-normal conditions for much of the next week. - No chance for precipitation through at least Monday. && .NEAR TERM... (Through Friday) Issued at 1215 AM CST Fri Dec 12 2025 Sensible conditions today will feature another "dip" in temperatures and gusty northerly winds (especially this morning). A weak surface front, currently passing the I-70 corridor in central Kansas, continues dive southward early this morning. While cooler than Thursday, a rather muted airmass response/change associated with the front, along with mostly clear skies, will allow temperatures to remain at or above average for most locations (near 50 degrees north to low-60s south). The immediate post- front looks to feature a notable (northerly) low-level jet during the morning/midday. As boundary layer mixing begins, periods of northerly wind gusts up to 30-35 mph are expected along and south of the Interstate 40 corridor. Ungar && .SHORT TERM... (Friday night through Sunday night) Issued at 1215 AM CST Fri Dec 12 2025 Conditions heading into Saturday morning will be rather benign, with early morning lows in the upper-20s north to near the freezing mark across the Red River Valley. A secondary, much stronger, frontal intrusion looks to occur throughout the daytime hours on Saturday. As a result, the high temperature forecast on Saturday is somewhat uncertain, with a 10+ degree spread in plausibly coolest and warmest conditions during the afternoon. Will opt to maintain a more "middle of the road" forecast for now, though temperatures may ultimately run several degrees warmer across western and southern portions of the area than currently advertised. The front will push southward into north-central Texas by Saturday evening, as a 1040+ mb Canadian high continues to dive southward across the Plains. Combined with a breezy north/northeasterly wind, single-digit wind chills are expected on Sunday morning across the northern two-thirds of Oklahoma. Sunday will be the coldest day in some time, with temperatures remaining at or just below freezing across northern Oklahoma. Ungar && .LONG TERM... (Monday through Thursday) Issued at 1215 AM CST Fri Dec 12 2025 The cold spell looks to be short-lived, with temperatures returning to a near or above-normal state by Monday. Outside of a more amplified upstream upper ridge, most global and ensemble guidance captures a compact southern stream wave moving across the region on Tuesday. While another frontal passage is possible with this system, sensible impact appears limited (or nil), with near to above-normal temperatures and mostly dry surface weather continuing throughout much of next week. Ungar && .AVIATION... (06Z TAFS) Issued at 1026 PM CST Thu Dec 11 2025 VFR conditions will continue with only high clouds expected. Southerly winds will shift to the north/northwest as a wind shift/cold front moves through tonight. Winds will become gusty tomorrow morning before weakening by late afternoon into the evening. Winds will begin to shift to the east/southeast across western terminals toward the end of the TAF period. Mahale && .PRELIMINARY POINT TEMPS/POPS...
