Thunderstorms are expected to develop on Tuesday across the Gulf Coast region and from the Four Corners northward into the north-central U.S. No severe threat is expected across the U.S. Tuesday or Tuesday night. ....Synopsis... A broad mid-level trough will impinge on the northwestern U.S. as upper ridging prevails over much of the CONUS on Tuesday. Surface high pressure will promote cool and stable conditions from the Midwest to the East Coast, limiting thunderstorm potential. However, orographic lift over the higher terrain in the Interior West, as well as surface lee troughing in the central and northern Plains, will promote at least isolated thunderstorm development during the afternoon and early evening hours. Steep lapse rates will overspread the northern Plains and Upper MS Valley regions by afternoon, promoting at least moderate instability, though the lack of low-level moisture should limit severe potential. The heating of rich low-level moisture along the Gulf Coast will encourage scattered thunderstorm development. By Tuesday, a tropical storm is likely to develop to the southeast of the TX coastline (per latest NHC forecast). The probable track of this developing tropical storm suggests that the more organized convection should remain offshore through Tuesday, which should keep any severe threat to a minimum. ...Squitieri.. 09/08/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
