Heavy Rain in North-Central U.S. & Scorching Heat in South-Central U.S. - 09-18 to 09-20

Updated Fri Sep 18th 2026, 5:45am PDT

This weekend, North-Central U.S. will face heavy rain and potential flash flooding, while South-Central U.S. experiences record-breaking heat. An upper-level system in the Pacific Northwest will bring showers and storms to the Great Lakes and Midwest. Meanwhile, hot temperatures will persist in the Southern Plains and Southeast with highs soaring into the 90s and 100s. Let's dive into the details for your area:

North-Central U.S. Heavy Rain Risk

From Friday through the weekend, an upper-level system will bring heavy rain and thunderstorms from the Northern Rockies to the Upper Mississippi Valley and the Midwest. We should prepare for potential flash flooding, especially in areas where rain may fall repeatedly. The system will bring a lot of moisture from the Pacific Northwest and move east towards the Great Lakes by Saturday, increasing the risk of heavy rain.

Mid-Atlantic/Southeast Showers and Storms

Parts of the Mid-Atlantic and Southeast will see a portion of the frontal system bringing showers and thunderstorms through Saturday. The presence of tropical moisture can cause heavy rainfall, particularly in Florida, with slow systems enhancing the risk.

South-Central U.S. Heat Wave

In the Southern Plains and Southeast, expect very hot and humid weather with temperatures reaching the 90s to low 100s through the weekend, possibly setting new records. Overnight lows will stay high, limiting cooling off periods. This will result in a Moderate to Extreme HeatRisk, so take precautions to stay cool and hydrated.

Southwest Decreasing Monsoonal Activity

The Southwest will see a decline in monsoonal thunderstorms as the activity shifts slightly east by Saturday. Some isolated storms might still pop up in the afternoons and evenings, mainly in hilly areas.
