Severe thunderstorms appear unlikely on Thursday. ....Synopsis... On Thursday, a leading shortwave trough will eject northeastward out of eastern MT and into SK/MB, shunting an upper ridge eastward into MN. To the west, a large area of cyclonic flow and cool temperatures aloft will remain over much of the Northwest. To the east, a weak upper trough will exist east of the MS River, providing cool temperatures aloft. Meanwhile, a surface ridge will exist over much of the same areas, with high pressure extending southwestward out of New England. Low pressure will develop over the central High Plains during the afternoon, beneath the weak upper ridge. Shear will remain weak across this area, but isolated daytime thunderstorms may form during the peak heating hours from parts of NM and the TX Panhandle northward into SD. This activity should generally be non-severe as moisture will be limited and there will be midlevel subsidence. However, locally gusty outflow winds will be possible with any activity there. Elsewhere, a higher probability of storms will exist over parts of IN, OH, KY and TN, beneath the cool temperatures aloft. Scattered rain or thunderstorms will be possible throughout the day in this area, with a few strong gusts possible. The overall severe threat appears low, given dry air aloft, weak shear and modest instability. ...Jewell.. 09/26/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
