Tropical moisture is being pushed westward by a strong ridge of high pressure dominating the eastern half of the U.S. Monday brought over an inch of rain in Lafayette as afternoon showers and thunderstorms moved through. As drier air nudges southwestward, our chances for rain will be squashed for the rest of the week.
Lower humidity will help keep our heat index below 100 degrees even though the actual temperatures will run as high as 95 later this week. Because the dry air will remain in place, even the overnight lows should drop closer to 70 degrees, perhaps a few northern areas will drop into the 60s at night.
The ridge should hold for the rest of the work week, and only slim chances for rain will exist for the upcoming Labor Day weekend.
The tropics are also quiet today. Tropical waves over the far eastern Atlantic might have some potential later this weekend, but shouldn't be a threat to any land. The Gulf and Caribbean should remain storm free for the rest of the week, models don't have anything significant developing over the next week or so.
