As expected....afternoon storm returned to the First Coast Thu. afternoon.  We'll now have at least 2 more days of numerous heavy showers & storms that will produce drenching downpours & lots of lightning.  A few strong to severe storms will be possible.  A severe storm produced a very local microburst in the Orange Park & Ortega area.  Check out the radar image below which shows the severe storm -- with lots of lightning -- entering Duval Co. from Clay Co. as the storm moved north along the sea breeze.  The microburst had estimated winds of 50-60 mph which dropped trees on several homes & at least one car.  Photos below from Rosalia Kaminski along Kernan, Jax S'side...Judi Rosenvold, Jacksonville..Richard Halligan, Mandarin.

Radar imagery below from the Jax N.W.S.:

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA, NASA and EUMETSAT satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.
Global climate trend since Nov. 16, 1978: +0.14 C per decade

June temperatures (preliminary)

Global composite temp.: +0.30 C (about 0.54 degrees Fahrenheit) above 30-year average for June.

Northern Hemisphere: +0.34 C (about 0.61 degrees Fahrenheit) above 30-year average for June.

Southern Hemisphere: +0.26 C (about 0.47 degrees Fahrenheit) above 30-year average for June.

Tropics: +0.22 C (about 0.40 degrees Fahrenheit) above 30-year average for June.

May temperatures (revised):

Global Composite: +0.08 C above 30-year average

Northern Hemisphere: +0.18 C above 30-year average

Southern Hemisphere: -0.02 C below 30-year average

Tropics: +0.11 C above 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Notes on data released July 9, 2013:

Global temperatures warmed in June to their warmest level since January, compared to seasonal norms, said Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville.

Compared to seasonal norms, during June the coldest area on the globe was off the coast of West Antarctica in the Amundsen Sea (between South America and New Zealand), where the average temperature was as much as 4.52 C (about 8.14 degrees Fahrenheit) cooler than the Antarctic’s winter seasonal norms. Compared to seasonal norms, the “warmest” area on the globe in June was also in the Antarctic. Temperatures just south of the Brunt Ice Shelf (along the coast between South America and Africa) were as much as 4.38 C (about 7.88 degrees Fahrenheit) warmer than seasonal norms for June.
