EXTREME WEATHER OUTLOOK

Updated by Henry Margusity

Weather Pattern Discussion

We remain in a period of relatively non-extreme weather across much of the country. By extreme weather, we're talking about conditions that are substantially outside the normal range for a particular location or time of year, whether that involves temperature, severe thunderstorms, flooding, or other significant weather events.

There is certainly plenty of heat across portions of the Southern Plains and Southwest, and that heat has persisted for several weeks. It will likely continue for a while longer, but from a climatological standpoint, much of this is not unprecedented. These regions routinely experience prolonged stretches of very hot weather during the summer months.

That doesn't mean the heat isn't uncomfortable or potentially hazardous. Prolonged temperatures well above normal can still create significant heat stress, particularly for people spending extended periods outdoors. However, the current pattern is better characterized as persistent summer heat rather than an extraordinary nationwide extreme-weather event.

Elsewhere, the weather pattern remains active at times, with thunderstorms and periods of heavy rainfall occurring across portions of the country. But overall, we're not currently seeing the type of widespread, exceptional weather anomalies that would define the entire national pattern as extreme.

The important point is to distinguish between persistent weather and truly anomalous weather. A heat wave that lasts several weeks can certainly have impacts, but duration alone doesn't necessarily mean the temperatures are historically extreme.

Overall, the current pattern remains relatively typical for the season, with persistent heat across the Southern Plains and Southwest and more variable conditions elsewhere, rather than a nationwide period of unprecedented extreme weather.
