287 FXUS64 KOUN 041836 AFDOUN Area Forecast Discussion National Weather Service Norman OK 136 PM CDT Tue Jun 4 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Wednesday) Issued at 135 PM CDT Tue Jun 4 2024 Main short term focus will storms late this afternoon into the overnight period, bringing both severe and flooding hazards. Storms are expected to initiate near a cold front / dryline triple point in west-central Oklahoma, then expand south and eastward through the evening. Continued moisture return and at least some diurnal warming will result in a highly unstable environment; this combined with adequate deep layer shear (~30 knots 0-6 km bulk shear) will result in an initial large to very large hail risk. Any discrete storms along the front will also have a low tornado risk. Low level shear will initially be low, ramping up with the low level jet around 00-02z. As storms form into a complex this evening (transitioning to a heavy rain and damaging wind threat), this will support MCS maintenance down through south central Oklahoma. This complex will likely take a similar path to last night`s complex, hitting areas that are already plenty saturated (1 and 3 hr flash flood guidance ranges from less than an inch to 2 inches through this area). Thus, a flood watch will be issued for parts of central and south central Oklahoma for tonight. Storms should exit the area by around 4am. Day && .LONG TERM... (Wednesday night through next Monday) Issued at 135 PM CDT Tue Jun 4 2024 With the passage of Tuesday`s cold front, most of the moisture should be pushed out allowing for a couple of dry days in the forecast. Ridging will impinge from the southwest late this week, though that won`t completely keep out the possibility of northwest flow. Low rain chances (20-30%) return Thursday night and continue through early next week, mainly during the overnight periods (it`s MCS season). Day && .AVIATION... (12Z TAFS) Issued at 550 AM CDT Tue Jun 4 2024 MVFR ceilings and some lower visibility will remain possible this morning and may linger into the afternoon wrt ceilings. Isolated storms this morning should remain outside the TAF sites. More storms expected to develop across north-central into central Oklahoma late this afternoon and then traversing south/southeast this evening and overnight. South winds will shift to the north behind a front that will enter northwest Oklahoma later this morning and move through all but DUA by this evening. && .PRELIMINARY POINT TEMPS/POPS...
