Storm Moving through the South; Pacific Storm to Impact the West this Weekend

A storm is expected to develop over the southern High Plains today and track to the Mid-Atlantic through Friday with showers and thunderstorms. On the northern edge, snow, ice, and/or a wintry mix is possible over the central Plains. A significant storm is expected to arrive late Friday through the weekend with rain, heavy mountain snow, and gusty winds for much of the West. Read More >

Severe Thunderstorms Strike Portions of Northern Indiana, far southern Lower Michigan and northwest Ohio

Hot, moist and extremely unstable conditions aided in rapid thunderstorm development across far northwestern Indiana around 2 pm EST. Initially a lone thunderstorm developed over northeastern Porter county, which rapidly intensified and became severe as the moved into Laporte county Indiana. Fig 1 below gives a look inside the severe thunderstorm. This view is called a Reflectivity Cross Section (RCS). A short but intense line of storms quickly developed south of this initial storm. This line would become the dominant damage producer across far northern Indiana as well as parts of far southern Lower Michigan and northwest Ohio.  The majority of the significant wind damage occurred from Laporte county, across southern St Joseph and northern Marshall counties and east from there. The strongest winds appear to have struck southern St Joseph county in Indian from North Liberty to Lakeville and then east from there.
