Temps. will stay warm through the weekend -- mid 80s to low 90s inland...low to mid 80s at the beaches.  Humidity will slowly creep up so that enough moisture should be available for the sea breeze to ignite a few isolated to widely scattered t'storms Sat.-Sun. but well inland between Highway 301 & I-75 & mostly west of Jax.  Cooling in the upper levels of the atmosphere combined with a couple of upper level disturbances should help afternoon storms increase some & possibly reach I-95 to the coast early next week.  I still don't see anything widespread anytime soon but where storms occur, there will be a period of very heavy rain.

Meanwhile....there's what's looking like the potential for a major severe weather outbreak at least 2 days in a row & maybe several days in a row beginning Sunday from the Southern Plains through the Upper Midwest -- Texas to Iowa & Illinois east to parts of the Ohio & Tennessee Valley's.  The slow moving storm system will eventually lift out far to the north of Jax....too far for any significant effects on the First Coast.

Speaking of severe storms, storm surveys are ongoing as the first significant multiple killer outbreak tornadoes of the year raked North Texas Wed.  At least 6 were killed which doubled the number killed by tornadoes so far this year (Jan. 30 - 1 killed in Bartow, GA...Feb. 21 - 1 killed in Sabine, TX...April 11 - 1 killed in Kemper, MS.).  The Fort Worth, Tx N.W.S. has identified at least 2 violent tornadoes -- an EF-4 & an EF-3 in addition to at least 11 other tornadoes.  Click ** here ** for very preliminary surveys including doppler radar images & a few damage photos...& ** here ** for a summary of all the tornadoes.

A volcano that "awakened" about 13 years ago 50 miles southeast of Mexico City in Mexico has become very active recently & could be building up to a major eruption.  The Popocatepetl volcano has not had a major eruption since 800 AD.  Click ** here ** to go to "Volcano Discovery", a web site that offers daily updates on the volcano.

Ride your bike!!.......
Earth Gauge: Bike to Work Week
May is National Bike Month and May 13-17, 2013 is Bike to Work Week. The U.S. Census Bureau’s American Community Survey shows that number of Americans commuting by bike has increased by 47 percent since 2000.  Hitting the road on two wheels has benefits for your health and the environment. Studies have shown that adults who bike to work have better weight, blood pressure and insulin levels; adolescents who bike are 48 percent less likely to be overweight as adults. Plus, leaving your car behind for even one trip saves gas, reduces air pollution and saves money. In 2012, traffic congestion in the U.S. wasted about 2.9 billion gallons of gas – enough to fill the New Orleans Super Dome four times – and the total financial cost of congestion was 112 billion dollars. That works out to about 818 dollars per commuter.
Viewer Tip: Try biking to work or school just one day this week. Research has shown that the length of about half of all car trips – three miles – can be covered as quickly on a bike when parking and traffic delays are taken into account. These resources will help you on your way:
• Find events for National Bike Month and Bike to Work Week  in your community.
• Plan a bike route using Google Maps.
• Get cyclist and pedestrian safety tips from the Federal Highway Administration.
