Dakota twisters; precursors to Sunday storms here

Sweaters and light jackets were back in style in Friday’s northeast winds. The flow limited Northerly Island on Chicago’s lakefront to 57°. But, peak readings the next two days surge 17° above last weekend’s levels.
Blistering Plains heat produced tornado-bearing t-storms late Friday in North Dakota. At least five twisters were reported from mammoth t-storms which towered nine miles above the region’s rolling landscape. While the heat remains locked in place to Chicago’s west this weekend, the t-storms may not. Patches of clouds off these storms blow into the metro area and mix with the day’s sun Saturday. Thundery weather could reach some sections late Saturday night. But, the atmosphere threatens to produce a fast-moving breed of t-storm beneath powerful jet stream winds Sunday. Such storms are notoriously high wind producers.
