Weather

A powerful storm is expected to move slowly across the Great Lakes on Tuesday. Drenching rain will develop northwest of the storm center, including much of Michigan, eastern Wisconsin and northern Illinois. Strong to severe thunderstorms are in store south and east of the storm. Storms may produce damaging gusts, hail, flash flooding and isolated tornadoes from eastern Ohio, western Pennsylvania and western New York to West Virginia, western Maryland and Northern Virginia. Storms may continue to bring high winds across central and northern New York and into the Middle Atlantic. A few heavy and gusty storms are in the forecast for the Gulf Coast and the Southeast.

Dry and slightly cooler air is expected to bring an end to the recent rain over much of the Plains. High pressure will build south.

Most of the West can expect fire weather to continue, with blazing sunshine and above-average temperatures. A pocket of moisture is expected to produce spotty thunderstorms over the interior Southwest. A few of these storms could bring blowing dust, flash flooding and strong winds. In areas where the storms do not produce rain, lightning strikes may ignite new wildfires.

Hurricane Lane may affect parts of Hawaii late this week. The storm is expected to turn more northwest and gradually weaken on Thursday and Friday. This will result in rain and strong winds across the western islands, including Kauai.
