As Tropical Storm Marie tracks near the Southwest, a surge of tropical moisture is possible.

The region could see monsoon thunderstorms capable of producing flash flooding in numerous cities, including Phoenix and Tucson, AZ. A Level 1 out of 4 flash flood risk has been issued across the region.

Meanwhile, the Central U.S. will continue to experience above-average temperatures. 

Minneapolis and Oklahoma City could see temperatures running 5 to 10 degrees above average, with mainly dry conditions expected, likely providing a picture-perfect forecast for those looking to end summer on a high note.

Sunday

As we move further into the holiday weekend, more of the same weather is expected on Sunday.

Monsoon storms will likely increase across the Southwest and Intermountain West. The unsettled pattern could keep temperatures cooler than average, marking a big change from the record heat the Southwest has experienced this season.

In Florida, afternoon thunderstorms are expected to decrease compared to Saturday but will continue, especially across southern Florida.

The Northeast will likely see a dry Sunday as a high pressure system quickly moves in from Canada, bringing seasonable temperatures.

Meanwhile, warm air will remain across the central and Southern Plains for another day.

Monday

On Labor Day, quieter weather is forecast to take shape across much of the country. Aside from lingering summer heat across the central and Southern Plains, seasonable temperatures are expected across the Heartland, Great Lakes and Northeast.

HOW HIGH PRESSURE AND LOW PRESSURE DRIVE THE WEATHER

While a few showers will be possible across the interior Northeast, a mainly dry holiday is expected.

However, more unsettled weather will remain across the Southeast and Florida as summertime thunderstorms continue and a cold front moves south, impacting areas from Atlanta to Miami.

WHAT IS A COLD FRONT?

Storms will also be possible across the Northern Plains and Upper Midwest as moisture rides along the northern edge of the ridge of high pressure, which will continue to keep the central U.S. warm.
