Our "summer of waterspouts" continued Thu. with at least 2 waterspouts not far offshore from Jax Beach. A couple photos below....first from Greg DiFranza with a nice spray ring at the base... #2 is from Marcus Taylor, Jax Beach showing a classic towering cumulus line with heavy showers. There's some pretty decent video that was sent to Action News -- click ** here **.... click ** here ** to see additional photos.

Here's the Mayport weather observing station report (ASOS) @12:32pm with the remark (RMK) that 2 waterspouts began at 12:28 3 miles to the east [occasional lightning ground in cloud, cloud to ground & overhead, thunderstorm overhead moving west:

Fri. will be hot with highs 90-95 & heat indices 100+. Isolated to widely scattered afternoon t'storms should pop & -- while locally heavy -- will be hit and miss. A weak cool front moving into the area Sat. will increase showers & storms before easterly onshore flow takes over Sun. & continues through most of next week.

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 and NASA 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.

August temperatures (preliminary)

Global composite temp.: +0.16 C (about 0.29 degrees Fahrenheit) above 30-year average for August.

Northern Hemisphere: +0.11 C (about 0.20 degrees Fahrenheit) above 30-year average for August.

Southern Hemisphere: +0.21 C (about 0.39 degrees Fahrenheit) above 30-year average for August.

Tropics: +0.01 C (about 0.02 degrees Fahrenheit) above 30-year average for August.

July temperatures (revised):

Global Composite: +0.17 C above 30-year average

Northern Hemisphere: +0.13 C above 30-year average

Southern Hemisphere: +0.21 C above 30-year average

Tropics: +0.07 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 Sept. 10, 2013:

Compared to seasonal norms, in August the coolest area on the globe was southern Greenland, where temperatures in the troposphere were about 1.97 C (about 3.55 degrees F) cooler than normal, 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. The warmest area was south of New Zealand in the South Pacific, where tropospheric temperatures were 2.82 C (about 5.1 degrees F) warmer than seasonal norms.
