Updated at 1138 PM CDT Tue Jul 7 2026 - Isolated to widely scattered storm Wednesday - Thursday with localized downburst winds possible. - Heat builds Wednesday into Thursday and heat advisories may be needed. - Storm chances trend higher Friday through the weekend and possibly into early next week. Temperatures likely near to slightly below normal through this same time frame. && .SHORT TERM... (Through Wednesday) Issued at 1138 PM CDT Tue Jul 7 2026 The weak frontal zone that currently extends through far SE OK will lift northward through the day Wednesday. Dewpoints will trend higher for most locals by afternoon and heat index values of 100 to 105 will be common. A brief window of heat advisory criteria may develop but confidence is low in both extent and duration at this time. Isolated afternoon storms are likely Wednesday afternoon most anywhere across the forecast area. Coverage likely remains low but will include mentionable precip chances to reflect the potential. Stronger storms will be capable of downburst winds. && .LONG TERM... (Wednesday Night through Tuesday) Issued at 1118 PM CDT Tue Jul 7 2026 Stronger wave moves into central Plains Wednesday night with the low level jet responding with a corridor of high based convection possibly spreading into NE OK late Wednesday night through Thursday morning. The veered low level flow and potential for lower dewpoints to mix eastward should result in the hottest temperatures of the week by Thursday afternoon. Heat advisory headlines appear likely at this time. Afternoon storm potential Thursday varies amongst model solutions but a low chance across northern locations appears warranted. This corridor will also be nearer slightly stronger flow so an uptick in severe potential could develop pending storm development. An MCS is expected to develop Thursday night across the High Plains and spread eastward toward the forecast area Thursday night into early Friday. This scenario carries uncertainties typical with MCS evolution, but the pattern is favorable and higher precip chances will be shown for northern portions of the forecast area. The pattern evolution over the weekend generally favors building ridging over the western CONUS which then becomes centered over the northern Plains by early next week. This keeps the local region on the periphery of the the upper ridge and allows for daily precip chances with temps near to possibly slightly below normal. && .AVIATION... (12Z TAFS) Issued at 626 AM CDT Wed Jul 8 2026 Few to broken mid clouds should remain common through this afternoon over the CWA. A slight chance of storms is also forecast through this afternoon as a frontal boundary lifts northeast through the region. With isolated coverage and uncertainty of impacting any one terminal will continue to keep TAFs dry at this time. Any convection that can move over a terminal will be capable of gusty winds and brief heavy rains. Mid clouds this evening should begin to dissipate ahead of increasing high clouds overnight tonight from a disturbance moving across the central Plains. A slight chance of showers/storms returns late in the period for parts of northeast Oklahoma. Winds through the period start out variable and become south to southwesterly during the day today. Winds aloft increase tonight and will carry low level wind shear for all TAF sites. VFR conditions should persist through the period. && .PRELIMINARY POINT TEMPS/POPS...
