919 FXUS64 KTSA 051126 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 626 AM CDT Sun May 5 2024 ...New AVIATION... .SHORT TERM... (Today) Issued at 300 AM CDT Sun May 5 2024 Showers and storms will overspread the area today as an upper trough axis will lift northeast from TX into AR and MO tonight. Pockets of heavier rainfall are likely to occur just about anywhere across the forecast area through the afternoon. Locally higher rainfall amounts today and saturated soils from previous convection across the area will maintain the flash flooding threat. Rain will begin to taper off from SW to NE this afternoon and evening as the upper trough lifts through the area. That said, the current expiration time of 00z Monday for the flood watch looks good and will leave as is. && .LONG TERM... (Tonight through Saturday) Issued at 300 AM CDT Sun May 5 2024 Lingering rain across the NW AR zones should end by 06z, leaving the forecast area dry for rest of tonight much of the daytime on Monday, though some model data hints at some elevated shower and storm potential Monday afternoon across SE OK and NW AR, so will keep a low Pop in those areas. Focus turns to storms that develop along the dryline to west later Monday afternoon in conjunction with an upper trough that lifts from the mountain west region into the high plains Monday afternoon and evening. Potential for some significant severe weather will exist with storms that northeast Oklahoma late in the afternoon or more likely Monday evening. Greatest coverage/higher end severe potential continues to favor NE OK and NW AR Monday eve/night. Despite lower storm coverage roughly from I-40 to the south, the environment will remain supportive of a higher end severe threat with any storm that develops. Coverage will diminish late Monday night and Tuesday morning, leaving most much of the area in a lull. However, will keep though low PoPs across the eastern sections of the forecast area Tuesday and Tuesday night. An uptick in storm chances will come Wednesday with a cold front that enters the area, with some severe potential in place ahead of the front Wednesday afternoon and evening. The boundary will push through the area by Thursday morning. Cooler and drier air will filter into the area starting Thursday. An upper trough in NW flow aloft will clip the area Friday, and may produce a few showers across NE OK and NW AR, however will leave PoPs out for now. Otherwise, settled conditions are expected for the remainder of the forecast period. && .AVIATION...
