FXUS64 KOUN 091720 AFDOUN Area Forecast Discussion National Weather Service Norman OK 1220 PM CDT Thu Jul 9 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1220 PM CDT Thu Jul 9 2026 - Scattered showers/storms are expected to continue to develop over northern Oklahoma into the morning hours. - Severe weather will be possible Thursday night into early Friday morning, and again Friday afternoon. - Hot and humid conditions expected to continue through the weekend with a risk for heat related illnesses. && .NEAR TERM... (Through Thursday) Issued at 131 AM CDT Thu Jul 9 2026 Isolated showers and thunderstorms will be possible this morning, mainly across northern Oklahoma. A few storms may produce gusty winds and small hail, but overall impacts are expected be very low. The more showery activity may reach as far south as the I-40 corridor by sunrise. Temperatures today will be a few degrees warmer than on Wednesday, where most of us will get up into the low 100s. Ambient surface moisture will remain in the upper 60s to low 70s through the day, especially across the eastern half of the area. That being said, afternoon heat indices are expected to get up to between 105-109 F across these locations. A heat advisory is in effect from noon to 8 PM for much of Oklahoma. A weak boundary that is expected to stall across northern Oklahoma today, may be the focal point for thunderstorms again this afternoon. Given the moisture in place, gusty winds will be possible with the strongest storms. Bunker && .SHORT TERM... (Thursday night through Saturday night) Issued at 131 AM CDT Thu Jul 9 2026 A more organized line of thunderstorms will move into the area late Thursday night into Friday morning. As these cluster of storms move in, they will be capable of producing strong to severe wind gusts and frequent lightning, along with locally heavy rainfall. There is a little more uncertainty with the position of the frontal boundary on Friday, which will be largely dictated by convection early Friday morning. This boundary will be the focal point for additional thunderstorms throughout the day. A few of these thunderstorms will be capable of producing large hail and damaging wind gusts. Another warm day is in store on Friday with afternoon temperatures reaching the triple digits for most of us. A few perturbations within the mid-level flow pattern will help support additional thunderstorm chances through Saturday across much of the area. A few stronger storms may be capable of small hail and gusty winds. Bunker && .LONG TERM... (Sunday through Wednesday) Issued at 131 AM CDT Thu Jul 9 2026 Temperatures through the latter half of the weekend into early next week will be 5-10 degrees cooler than what we will see over the next few days. A mid-level ridge across the Desert Southwest will shift to the north, and move into the central and high Plains. Across our area, we will see mostly dry conditions and a warm up back into the mid to upper upper 90s for the latter half of the week. Bunker && .AVIATION... (18Z TAFS) Issued at 1220 PM CDT Thu Jul 9 2026 A few isolated storms are possible this afternoon (mainly north of I- 40), but confidence is too low for mention in TAFs. Storms will be possible again overnight across northern Oklahoma (prob30 at KWWR for this possibility). Any storms that develop today and tonight will be capable of lightning and gusty/erratic winds. Otherwise, VFR conditions with breezy south to southwest winds this afternoon, diminishing overnight and becoming gusty again tomorrow. Some marginal low level wind shear is possible toward morning, but confidence is too low for mention in TAF. Day && .PRELIMINARY POINT TEMPS/POPS...
