HUNTSVILLE, Ala.– The updated U.S. Drought Monitor released Thursday morning showed drought conditions expanding by about 10 percent over Alabama in the past seven days.

Much of the Tennessee Valley remains under a moderate drought while parts of DeKalb, Jackson, Madison, Marshall and Morgan Counties are included in a severe drought.

This time of year, very organized rain is usually hard to come by. Think back to the scattered storms that rumbled around the Valley about seven days ago; some tremendous rain fell over a few areas while other spots only got light showers.

In June, the jet stream (steering current in the atmosphere where large storm systems track) lifts farther north toward the Canadian border. This is where severe weather is occurring across parts of Montana Thursday afternoon. This overall pattern is unlikely to break down again until after summer, but added humidity does promise the chance of more scattered, heavy storms again next week.

Scattered storms become likely by Monday, but the best chance of some downpours comes Tuesday, Wednesday and Friday of next week. Forecast guidance suggests a good soaking for most communities by next weekend. Rainfall potential ranges from around one-half inch on the low end to as much as three inches on the high end.
