Isolated strong to severe thunderstorms are possible on Saturday across parts of the Northeast, southern and central Plains, and northern Rockies. ....New England... A weakening surface front will move into New England on Saturday from southeast Quebec. Modest southwesterly mid-level flow overhead will be located southeast of a large mid-level low/trough centered over southern Hudson Bay. Diurnal heating of an adequately moist boundary layer will favor the development of weak to moderate buoyancy across New England by early afternoon. A few stronger storms will be capable of a marginally severe hail threat and perhaps locally damaging gusts. ....East-central TX... The western portion of a cold front associated with a mid-level low over the southern Appalachians, will slowly push southward across parts of east TX and LA. A reservoir of low-level moisture from the Upper Coast of TX north-northwest into north TX will feature upper 60s to 70s dewpoints. Strong heating and weak convergence along the boundary will may lead to isolated thunderstorms developing during the afternoon. The risk for isolated severe is contingent on storms developing and the latest CAMs depict sparse storm coverage. This activity will likely dissipate by the early evening. ....Mid MO Valley southwestward into central High Plains... A ribbon of slightly enhanced 500-mb flow (30 kt) will extend from the central Rockies into the central Plains located to the northeast of a mid-level anticyclone located over northwest Mexico. A remnant front will become draped over parts of the south-central High Plains and an inverted surface trough will extend into the mid MO Valley. Within this general corridor, an axis of moderate instability is forecast to develop during the day. Isolated to scattered thunderstorms will probably develop during the afternoon into the early evening. Forecast soundings indicate hail/severe gusts are possible with the stronger storms. ....Northern Rockies... A relatively confined area of weak instability is forecast over the region on Saturday with moderate straight-line hodographs. The latest model guidance indicates scattered thunderstorms will develop amidst relatively cool mid-level temperature profiles (-14 deg C at 500 mb). Some of the stronger storms will favor hail growth and severe gusts may accompany the stronger cores. ...Smith.. 09/08/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
