520 FXUS64 KTSA 170157 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 857 PM CDT Sun Jun 16 2024 ...New SHORT TERM... .SHORT TERM... (The rest of tonight) Issued at 857 PM CDT Sun Jun 16 2024 Latest water vapor imagery shows the forecast area sandwiched in- between mid/upper-level ridging along the eastern CONUS and a deepening trough over the Pacific NW/Great Basin regions. A few diurnally-driven showers tried developing across portions of northwest AR earlier this afternoon/evening. However, despite the very warm temperatures, with very weak forcing in the low/mid- levels, they were unable to sustain themselves more than just a few minutes. With the sun setting, the existing low precipitation chances will diminish completely over the next hour or sooner and the remainder of the evening will remain rain-free. Overall, the forecast for the remainder of the night remains on track, with very little changes made from the afternoon forecast package. Another abnormally warm night is expected with low temperatures bottoming out in the low-mid 70s. Mejia && .LONG TERM... (Monday through Sunday) Issued at 214 PM CDT Sun Jun 16 2024 Several of the CAMS suggest a broken line of showers/thunderstorms will begin to propagate northward from the Gulf during the day Monday. There is a slight chance (20 percent) some of this activity could move into far southeast Oklahoma by late afternoon or early evening, but more likely will begin to dissipate. Regardless, increasing low level moisture, coupled with strong afternoon heating, may allow for a few isolated storms to develop across far SE OK/NW AR. Overall coverage again will likely remain limited. High temperatures will remain a few degrees above normal with heat indices approaching triple digits in some locations. Slightly cooler conditions are expected during the Tuesday-Thursday time frame as winds become more easterly. Increasing high clouds are also expected from tropical system, which is forecast to move westward across south Texas. Rain chances will remain low, and again be confined to far southeast Oklahoma on Wednesday. Warming trend returns late week into the early part of next weekend as upper ridge builds back over the southern Plains. A weak frontal boundary may approach from the north on Sunday and therefore kept slight chance NBM PoPs for NE OK/NW AR. Parts of northeast Oklahoma have received little rainfall over the past two weeks and with no significant rain forecast through the extended period and potentially beyond, abnormally dry conditions may become a concern. && .AVIATION... (00Z TAFS) Issued at 634 PM CDT Sun Jun 16 2024 VFR conditions will prevail through the forecast period. South winds will gust over 20 knots at times at the northeast Oklahoma and far northwest Arkansas sites during the day Monday. && .PRELIMINARY POINT TEMPS/POPS...
