Scattered severe storms are forecast from the Arklatex region across the Gulf Coast States/East Coast States and vicinity on Sunday. Isolated severe storms will be possible across portions of the Plains/High Plains. ....Arklatex across the Southeast... An ongoing cluster of storms -- potentially well-organized -- is forecast to be moving across parts of Oklahoma toward the Arklatex region at the start of the period. This convection will be associated with a mid-level short-wave trough digging east-southeastward, through larger-scale west-northwesterly cyclonic flow aloft. In tandem with the advance of this feature, expect storms to progress across the lower Mississippi Valley area and the Gulf Coast states through the afternoon, as the airmass heats/destabilizes ahead of the ongoing convection. With strong lower- to middle-tropospheric flow accompanying the compact upper system, risk for damaging wind gusts is apparent with fast-moving storms. Some hail will also be possible, with convection reaching the southern Appalachians into the evening before weakening diurnally. ....East Coast States... As mid-level troughing shifts across the Appalachians during the day, a weak surface trough/front should focus scattered thunderstorm development, as diurnal heating contributes to ample destabilization. With moderately strong southwesterly flow through the lower and middle troposphere anticipated across the region, locally severe storms will likely evolve through the afternoon and into the early evening hours. Locally damaging wind gusts, along with some hail risk, can be expected with the strongest storms. ....Northern Plains... Modest destabilization is forecast across portions of the Minnesota vicinity, ahead of a cold front forecast to shift southward out of the Canadian Prairie. While degree of instability will likely limit storm intensity in most areas, favorably strong flow aloft suggests potential for gusty/damaging winds with a couple of the strongest storms through late afternoon/early evening. ....High Plains... Isolated afternoon storm development will be possible across portions of the High Plains, with short-wave ridging aloft expected to limit coverage as compared to prior days. Still, with moderately strong northwesterly mid-level flow atop low-level southeasterlies, shear will support organized/severe storms. Thus, local risk for large hail/damaging winds is apparent through early evening. ...Goss.. 07/08/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
