520 FXUS64 KTSA 010451 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 1151 PM CDT Fri May 31 2024 ...New AVIATION... .SHORT TERM... (The rest of tonight) Issued at 917 PM CDT Fri May 31 2024 Mid-level low/shortwave trough has shifted northeast of the forecast area and is currently centered over southwest MO. Wrap- around moisture and an apparent low/mid-level boundary on the southeast side of the low continues to generate a few showers and thunderstorms, mainly affecting portions of far eastern OK and into northwest AR. Precipitation chances will gradually decrease and move eastward through at least midnight (perhaps an hour or two beyond midnight across far northwest AR) as the mid-level trough continues to lift northeastward. A few rumbles of thunder cannot be ruled out, though any thunderstorm activity should be relatively short-lived. Rainfall amounts are expected to be light, on the order of a few hundredths to a couple of tenths of an inch under heavier showers/storms. After midnight, patchy to areas of fog will be the main focus for the forecast area. Latest model guidance suggests increasing fog development, first forming across far northeast OK and far northwest AR, then spreading westward/southwestward through the overnight hours. There remains some uncertainty on exact coverage and density of the fog at this time. As the mid-level trough continues to lift northeastward, surface winds will further decrease and dewpoint depressions are expected to shrink through and after midnight. Went ahead and maintained widespread patchy fog across the forecast area, mostly after 3 AM, but did include areas of fog for northeast OK, far northwest AR, and locations near the Red River a few hours on either side of sunrise Saturday. Mejia && .LONG TERM... (Tomorrow through Friday) Issued at 225 PM CDT Fri May 31 2024 A relatively quiet day in the recent unsettled pattern anticipated Saturday, though there is some suggestion in model data of a weak remnant circulation associated with any more organized clusters of storms maintained overnight tonight, could drift over the region. Most CAM solutions do develop at least isolated storms across parts of the area, but coverage would likely remain quite limited. A somewhat higher chance of a storm complex maintaining into eastern OK Sunday morning continues to be suggested, albeit in a weakening state. The unsettled pattern continues early next week, with an overall trend toward hotter and more humid conditions. Some potential continues for a few more days for storm complexes to organize to the west and move into the area, with Sunday night into Monday still looking like the period of highest probability at this time. && .AVIATION... (06Z TAFS) Issued at 1148 PM CDT Fri May 31 2024 Ongoing storms across NW AR are likely to wane and gradually move east over the next several hours with minimal impact to local terminals. Otherwise, a widely varying mix of cloud heights and eventual fog development will complicate the forecast through the mid morning hours. Thereafter, a trend toward rising ceilings and/or eroding fog will lead to VFR conditions by afternoon. Any afternoon storm coverage is expected to remain too isolated to warrant mention. && .PRELIMINARY POINT TEMPS/POPS...
