Area Forecast Discussion National Weather Service Norman OK 252 PM CDT Wed Jun 18 2025 ...New NEAR TERM, SHORT TERM... .KEY MESSAGES... Updated at 244 PM CDT Wed Jun 18 2025 - Severe thunderstorms are possible today and into the evening hours. - Above-average temperatures and dry conditions Thursday and into early next week. Could see heat indices from 100-105 degrees Friday. && .NEAR TERM... (Rest of today and tonight) Issued at 244 PM CDT Wed Jun 18 2025 Parts of our forecast area will be under a risk for severe storms this afternoon into the evening. Our cold front/surface moisture boundary was stalled across northwest Oklahoma while guidance suggesting it will remain nearly stationary. Expecting much of the stratus to erode or break up at least north of I-44 as afternoon heating destabilizes the air and breaking the mid-level cap for convection initiation. Although the cap should hold near and well behind the surface front, expecting initiation south of I-40 with the higher severe risk near, south, and east of the I-44 corridor where the strongest moisture & instability will be. Strong surface- based instability up to 4000 J/kg of CAPE in the higher risk area could support supercell thunderstorms capable of producing large hail and damaging wind gusts into the evening hours. Although tornados are possible with any supercells, that risk will be lower as the deep-layer shear values decrease with the exiting shortwave. Expecting any convection to ramp down toward the midnight hours when storm POPs are completely out of our forecast. && .SHORT TERM... (Thursday through Friday night) Issued at 244 PM CDT Wed Jun 18 2025 An upper ridge over the western U.S. starts building in on Thursday starting a drying trend as far as rainfall. We'll also see hotter slightly above normal temperatures under the ridging with widespread 90s highs. South winds increase on Friday with a tightening pressure gradient keeping it breezy and a bit gusty during the afternoon while mixing into increasing low-level jet flow. Moisture advection from the southerly flow will maintain muggy/humid conditions as well producing 100-105 degree heat indices on Friday afternoon. && .LONG TERM... (Saturday through Tuesday) Issued at 125 AM CDT Wed Jun 18 2025 Warm, breezy, and dry conditions continue over the weekend. Low shower and storm chances return early next week as an upper trough moves over the western CONUS. && .AVIATION... (18Z TAFS) Issued at 1212 PM CDT Wed Jun 18 2025 MVFR/VFR ceilings this TAF period. Additional scattered showers/storms will be possible this afternoon/evening, mainly in parts of southern OK and western north TX. Strong variable winds and hail will be possible with some of the storms. Due to a boundary over the area, with additional boundaries possible due to outflow, shifting winds are expected into tonight. However, winds should overall become southerly Thursday morning. && .PRELIMINARY POINT TEMPS/POPS...
