SPC Jul 26, 2022 Day 4-8 Severe Weather Outlook

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0318 AM CDT Tue Jul 26 2022 Valid 291200Z - 031200Z ...DISCUSSION... The mid/upper-level trough that will persist over the north-central and northeast CONUS for much of this week is forecast to accelerate eastward on D4/Friday and be offshore of New England by D5/Saturday. In its wake, a weaker trough may redevelop from the northern Plains into the OH Valley and Northeast, as an upper ridge amplifies over the West. For D4/Friday, some severe threat may develop across parts of the Mid Atlantic and Southeast in association with the departing mid/upper trough, though guidance varies regarding the magnitude of instability and deep-layer shear along/ahead of the cold front. Some severe threat may also evolve across parts of the central High Plains (and eventually into the northern Plains) from D4/Friday into the weekend, as moist low-level flow is maintained into the region to the west of a surface ridge covering much of the eastern CONUS. None of these scenarios appear to warrant 15% severe probabilities at this time. Predictability begins to wane by D7/Monday, though organized severe potential appears relatively limited into early next week. Read more CHECK UPDATE ZOOM GRAPHIC
