Tropical Storm Dorian Fizzles Out in Dry AirJuly 25th, 2013 at 2:24 am by Bill Steffen under Bill's Blog, News, Weather
Tropical Storm Dorian weakened to just a few showers/t-showers. It couldn’t overcome the dry air ahead of it. Another tropical batch of rain will move up over Nantucket and into Nova Scotia over Sun./Mon. Here’s the last forecast discussion, forecast advisory, public advisory, (in Spanish), the latest Funktop Satellite loop of the storm (right side of the movie), the Visible Satellite Loop, the Water Vapor Loop (showing a fair amount of dry air ahead of the storm, which will keep it from intensifying rapidly. The U.S. has now gone the longest period of time since records began in 1851 with a major (Category 3 or higher) hurricane hit, nearly 8 years. The ACE Index measures the number and strength of tropical storms, and as you can see at the link, the ACE Index has been falling since the mid 90s in generally and significantly since 2005, the year of Hurricane Katrina. Hurricane Sandy was only a Category 1 storm when it hit the U.S. mainland.
Also, the weekend looks cool – the overnight European model gives G.R. 0.35″ of rain from Friday into Sun. AM and highs Saturday struggling to the upper 60s to low 70s with our 850 mb temperature down briefly to +4.2 – pretty cool for late July. I’m going to Maranda’s Park Party today and then to Picnic Pops with my 94-year old mother this Thurs. evening.
