Strong to Severe Thunderstorms in the East; Heat in the Central and Western U.S.

Strong to potentially severe thunderstorms with damaging wind gusts are forecast Thursday from parts of New England into the Mid Atlantic and Carolinas. Significant heat will expand across the West and Central Plains through Friday, potentially breaking daily high temperature records. Dangerous heat will then build into the Eastern U.S. this weekend through much of next week. Read More >

As images continue to pour in from the new GOES-16 satellite (preliminary, non-operational data), we continue to see interesting features. The image below is from this morning's (Tuesday, 5/30) upper-level water vapor channel, and they show the many swirls going around a much large upper level low pressure system centered over Hudson Bay in Canada. The high resolution of the satellite allows us to see multiple smaller centers of low pressure aloft, which can each have an impact on our forecast. One of these swirls, getting ready to enter central North Dakota, will bring a chance for showers and perhaps a storm this evening.

The image below numbers each of the swirls identified within the image above. There were 10 swirling in the image above around the larger low pressure system over Hudson Bay.
