Strong to severe storms have raked across portions of the central Appalachians and Mid-Atlantic Saturday afternoon and evening. Reports of hail to the size of golf balls (1.75 inches) and wind gusts 60-65 mph have been received. Major cities like Pittsburgh, PA and Baltimore, MD were affected. The storms passed off the coast around midnight.

The storm will move slowly off to the southeast in the next few days, but heavy winds and rains could linger along the coast for the next day or two.
Storms over the Central High Plains haven’t gone severe yet as of 5 pm CT. However, conditions are favorable for severe cells in western Nebraska within the next hour or two. These cells will develop and move southeast towards central and eastern portions of the state as well as the Kansas border area. An organized squall line could develop this evening that would enhance the threat for high winds.
Large hail up to two inches will be likely in western and central Nebraska. Gusty, damaging winds to 75 mph will also be a threat. The tornado threat remains minimal. Conditions are less favorable towards the Missouri Valley, so the severe threat should weaken early Friday morning.
Storms have blossomed over portions of northern Argentina tonight. You can see the greens and reds blow up near the middle of the satellite animation below. These storms will tend to move southeast overnight and into Friday. Very heavy rainfall will occur with these storms, leading to flash flooding.
The heaviest rainfall of 100-200 mm are expected over portions of northwestern Argentina and western Uruguay, including Buenos Aires and areas to the north. Localized amounts exceeding 200 mm will probably occur. These torrential rainfall amounts will lead to flash flooding in spots. Storms will weaken later on Friday with the flooding threat diminishing.
