The atmosphere will be loaded with instability or storm fuel from the middle to end of next week. This is one of several important factors we look at to get a severe weather event to occur. So far, the warm sectors looks broad, which could make for an expansive risk of severe weather some of the days later next week. The learning products are starting to catch onto this as well with severe weather probabilities to some extent starting Wednesday.

DERECHO AND THREAT TODAY AND TONIGHT DAKOTAS AND MINNESOTA

We are chasing the threat of a strong, long-lived wind bag event or derecho this afternoon and overnight, including the potential for with early supercells or any renegades that can develop ahead of the bow. 100+ mph wind gusts will be possible within the wind bag. Tornadoes will also likely be embedded in the line from the apex of the bow and north. Full-blown mode has been activated!

Stay tuned to severe weather watches and warnings in the target area!

MONDAY JULY 28 EARLY AM UPDATE:

Some isolated areas of flash flooding will continue to be possible overnight in association with a line of thunderstorms. This area of concern is across northwest Iowa as outlined by the green line.

Rainfall rates with the remaining stronger storms around the southwest flank of the convective mass will still be capable of reaching 1 to 2 inches/hour, and with some localized cell-training concerns, some additional rainfall totals of 2 to 4 inches will be possible.

SEVERE & TORNADO RISK UPGRADE🌪 ⬆: Confidence is INCREASING for a more robust severe weather event later this afternoon and into the evening across the Central Plains, which could yield a couple of tornadoes. TORNADO THREAT was also INCREASED in the latest outlook by SPC (especially across Northeast Nebraska & Western Iowa).

The thunderstorms that develop near the surface low will encounter a strongly unstable and moderately sheared environment supportive of initial supercells capable of all severe hazards, including baseball sized hail and tornadoes. This activity should quickly grow upscale, with the resulting convective line pushing southeastward into more of northeast NE and western IA. Given ample buoyancy downstream, some significant wind gusts are possible as this line moves eastward/southeastward.
