Tuesday will be another day of typical summer-time showers and thunderstorm activity across much of the Eastern Contiguous United States. However, some locations will remain dry and very hot.

A stalled front stretching from Texas to the Mid-Atlantic will bring scattered showers and thunderstorms to much of the eastern half of the lower 48 today. Stay tuned to the WeatherRadar and remain vigilant, especially if you've had heavy rain recently, as the risk of flash floods is higher due to saturated soils.

Meanwhile, the West continues to experience intense heat and dry conditions, with temperatures peaking today or tomorrow. By mid-week, the heat wave will shift east into the Northern Plains. Cities like Salt Lake City, Boise, Idaho and Billings, Mont., are expected to approach record-high temperatures on Wednesday and Thursday.

A low-pressure system south of southern Mexico has a low chance of developing as it moves west-northwest. Similarly, another tropical system south of Baja California is moving northwest with a low chance of development over the next 7 days. Neither system poses a risk of land impacts during this period.

When heat builds, and a front nears, the atmosphere's natural response is to produce storms. Under the right conditions, these storms can become strong or even damaging. Always stay storm-aware with our automated alert system. Here's how you can turn it on!
