Friday morning thunder ahead?
Next rain chance develops Thursday night into Friday.
Our beautiful summery August weather pattern continues through Thursday. So let's focus ahead a bit toward our next rain chances for Minnesota.
Another hot front will nudge toward southwest Minnesota Thursday night into Friday. Highs Friday will; push toward 100 degrees again in South Dakota and Nebraska. Highs Friday afternoon will nudge 90 again in southwest Minnesota.
But that steamy air mass will bump into relatively cooler air across Minnesota Thursday night and Friday morning. That’s a favorable environment for nocturnal thunderstorms to develop near the warm front Thursday night into early Friday.
NOAA’s GFS model grabs hold of the idea of a northwest to southeast oriented band of rain and thunder running from North Dakota through much of central Minnesota Thursday night into Friday morning. The loop below runs between 7 pm Thursday and 7 am Friday.

Stay tuned.
