KEY MESSAGES

- After a brief stretch of drier weather, widespread shower and thunderstorm chances will return this weekend.

- We'll be monitoring the potential for increasing heat danger early next week.

DISCUSSION

Issued at 328 AM CDT Thu Jun 4 2026

In the near term, we'll see a brief reprieve from higher humidity levels as surface high pressure remains centered over the southeast CONUS. This will change quickly however when a shortwave trough in the subtropical stream approaches and increases southerly low level flow and dramatically increases deep layer moisture in our region. While this pattern will bring high end rain chances, the QPF does not suggest we'll have significant heavy rainfall/flooding concerns. Moving into next week, global models are in good agreement for the subtropical ridge to rebuild and bring an increase in heat and humidity. The Mon-Wed time frame will be a time frame to watch for impactful heat stress, but there is not quite enough evidence at this point to provide any formal messaging. /EC/
