Heat wave criteria may be reached in many parts of the coverage area. For a heat wave to be "official," there must be three consecutive days of actual high temperatures above 90 degrees. Most parts of the coverage area hit 90 today, and most areas should hit 90 again on Monday, excluding coastal areas. Tomorrow will be a close one for many areas.
Heat wave criteria will likely be met again later this week, with another surge of above average temperatures. Saturday looks to feature the highest heat indices, with temperatures in the 90s and high humidity. If theirs any chance we'll have a "memorable" type of heat this July, it looks like Saturday has the best shot. A severe threat will also loom Saturday night, but that's too far out to get into any specifics.
While heavy thunderstorms have offered some improvement to drought conditions in the northeast, the drought continues to expand and worsen. Severe drought conditions are now present in New York, Massachusetts, New Hampshire and Maine.
With no big rainstorms in sight, these conditions should worsen. One of the reasons for this lack of rain, is due to the lack of tropical activity. A little less than a month ago we had the earliest named "D" storm on record form. Since then we have seen no tropical activity, mainly caused by the massive amount of dust coming off the Saharan Desert in Africa. When dust moves west of northern Africa, it interacts with tropical waves and weakens them. Some years the dust is more prevalent, and this year, there's so much dust that it can be seen in Texas, especially around dusk.
