485 FXUS64 KOUN 152301 AFDOUN Area Forecast Discussion National Weather Service Norman OK 601 PM CDT Tue Jul 15 2025 ...New AVIATION... .KEY MESSAGES... Updated at 559 PM CDT Tue Jul 15 2025 - Rain chances continue this evening, highest in southeastern Oklahoma. - Rain chances return to northern and central Oklahoma Wednesday night and Thursday as a weak front approaches. - Hot and humid towards end of the week into early next week. && .NEAR TERM... (Rest of today and tonight) Issued at 1205 PM CDT Tue Jul 15 2025 Trough axis that has been persistently over the area since late last week continues to be stretched from Missouri southwest across Oklahoma southward into southwest Texas today. There is a MCV located over southwest Texas and it will move gradually northward today, but should remain to our south. Otherwise, abundant moisture remains in place and with daytime heating and proximity of the trough, expect to see isolated to widely scattered showers and thunderstorms this afternoon. Most of the activity is expected to remain along and south and east of the I-44 corridor. GFS remains more aggressive than most models with maintaining shower and storm activity overnight. It appears to be having some convective feedback issues, but will look at keeping some low pops for southern Oklahoma overnight tonight with trough still present and some other models hinting at possible precip. && .SHORT TERM... (Wednesday through Thursday night) Issued at 1205 PM CDT Tue Jul 15 2025 Trough weakens Wednesday, but there still appears to be a residual low, likely associated with Tuesday`s MCV over Texas, that will be in the area. This again may aid in the possibility of an isolated shower or two Wednesday afternoon, but by this time confidence is not high enough to introduce precip chances outside of what NBM initializes. Meanwhile, a shortwave trough will move through the northern and central Plains Wednesday. Associated front will push south through Kansas on Wednesday with pre-frontal 850MB thermal ridge in place. This will likely result in surface temperatures climbing above the century mark across portions of northern Oklahoma Wednesday afternoon. Surface cold front will push south entering northwest Oklahoma Wednesday night, bringing rain chances back to that part of the state. This should also cool temperatures 10-15 degrees across the north for Thursday. Models differ on how far south they bring main synoptic front, but either the front or the possibility of precip-induced outflow boundaries may bring rain chances as far south as I-40 Thursday. Front then looks to wash out or retreat back northward Thursday night with some rain chances lingering across the north. && .LONG TERM... (Friday through Monday) Issued at 1255 AM CDT Tue Jul 15 2025 Models show the upper high trying to begin to build into the region towards the end of the week with high pressure influencing much of the area over the weekend into early next week. This will bring a drier forecast to much of the area. Temperatures are also expected to gradually warm with highs expected to become more consistent in the mid/upper 90s to low 100s over the weekend into next week. Unfortunately, we won`t be getting rid of the humidity quickly. With the hot and humid conditions, triple digit heat index values will become increasingly likely across at least portions of the fa. Heat advisories could be needed for multiple days later this week into early next week. && .AVIATION... (00Z TAFS) Issued at 559 PM CDT Tue Jul 15 2025 A few isolated showers and storms will continue to be possible over southern Oklahoma and north Texas this evening. Breezy southerly winds will diminish at most sites this evening, then become breezy again late tomorrow morning. VFR conditions will prevail. Day && .PRELIMINARY POINT TEMPS/POPS...
