WeatherTalk: More humidity but fewer big storms

Severe weather is not as frequent as earlier in the summer because the upper level winds are weaker.

FARGO — In addition to the shortening day length, the percentage of thunderstorms which turn violent has decreased noticeably the last few weeks. This, despite the air being quite humid much of the time. Even some of the cooler days recently have felt a little humid. In spring and early summer, storm systems had to raid the far southern part of the United States, near the Gulf of Mexico, to find high humidity. Since the spring began, however, many storm systems have done that, so that our air is now inherently humid.

Despite the humidity, severe weather is not as frequent as earlier in the summer because the upper level winds are generally weaker than earlier in the summer. Those upper winds will steadily increase this fall, but by then the air will have become too cool and dry to make strong thunderstorms most of the time.
