Morocco hits 121°F (49.6°C): a national all-time heat record

The first new all-time national temperature record of 2012 belongs to Morocco, thanks to the 121.3°F (49.6°C) temperature measured at Marrakech on July 17, 2012. According to the Wunderground International Records data base maintained by our weather historian, Christopher C. Burt, the previous record was 120.4°F (49.1°C) at Agadir on July 30, 2009. A hotter temperature of 51.7°C (125.1°F) was reported from Aghadir (Agadir) Souss Massa Dra region on 17 August 1940 during a chergui wind event. However, this reading is considered unreliable by weather records researcher Maximiliano Herrera, since the temperature was 6°C higher than that measured at nearby stations.

Seven nations set all time heat records in 2011. Nineteen nations (plus the the U.K.'s Ascension Island) set all-time extreme heat records in 2010. One nation (Zambia, in 2011) set an all-time cold record during the period 2010 - 2012. With a very hot airmass in place over much of North Africa, the Middle East, and Western Asia the remainder of this week, more all-time national heat records may fall.


Figure 1. A sample image of what the new Fire Risk layer on our wundermap looks like. This is the Keetch-Byram Drought Index, one of several indices that can be used to measure fire risk. Blue and green colors represent lower risks, while yellow and orange colors show higher risk. The highest risk is shown in dark red. The legend for the Fire Risk layer explains that these highest risk areas are often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.

Wunderground releases new fire risk layer on its wundermap
Our interactive wundermap, which allows one to overlay multiple meteorological data sets, has a new layer: a Fire Risk layer. Using data from the U.S. Forest Service's Wildland Fire Assessment System, we give you option to plot up U.S. fire danger using a variety of options: Fire Danger Rating, Lower Atmosphere Stability (Haines Index), Keetch-Byram Drought Index, 10-hr Dead Fuel Moisture, 100-hr Dead Fuel Moisture, and 1000-hr Dead Fuel Moisture. According to the National Interagency Fire Center, California currently has the most number of of large fires burning of any state (5), which makes sense, given what the fire risk map above is showing.

There is a picture of an American sub surfaced at the north pole taken in 1957 or 58 that shows open ocean and ice flows as well. Pic was taken in March if I remember correctly.

"The mission of the submarines was to collect scientific data and test submarine force readiness under Arctic conditions without logistics base support," a Pentagon statement said. The announcement was held up until the three submarines, identified as the Hawkbill, the Ray and the Archerfish, returned to their home ports, Navy officials said.

ahhh, the Cold War, those were the best of times.

Interesting, don't think ten people gave me a minus in that two minute time span for that comment. I may be wrong, but that may be one of those truths some may very much not want heard. Never seen a comment poof so fast, very fishy. I posted much, much more controversial ones and not had any of them poof ever. Had a couple of community violations but that's different. Hummmmmmmm


Didn't see but enough already- get over it and keep up your regular god postings.

From Nasa's Hurricane webpage:

ATLANTIC - Watching three tropical waves today.
1) Eastern Tropical Atlantic from 19N2 9W to 13N 28W. Limited moisture and a layer of dry Saharan air.
2) Wave headed to Lesser Antilles from 19N 55W TO 11N 54W and moving west. Has limited shower activity due to more Saharan dust.
3) Eastern coastal waters of Yucatan Peninsula, moving west and bringing scattered t-storms west of 85W, inland across the Yucatan.

Kinda already discussed it today, put up the anomaly map, that odd invest/test going on in the area, recent gfs runs.


Clouding in here, had a few sprinkles that may just be induced from the particles from the swamp fires burning west of me. Just got below 90ºF! I'm going outside:)

I would welcome opinions about this.. we have managed to escape the best of the weather here in NYC so far, with heavy/severe weather off to the west, south, and northeast. Does this make us more likely to see some rapid intensification of the storms that make it here given that 1) the local area has not experienced a significant amount of turbidity (sp?); 2) The heat remains and 3) the on-shore flow from the Atlantic.

would welcome opinions about what we may experience the rest of the afternoon. (Most importantly, I need to know if I should have another cup of coffee here at work)

yeah, that's a twisting of atmospheric winds, like i was mentioning.. this occurs as wind directions change at different heights going up the atmosphere. there is enough lift on these updrafts that they can penetrate these wind-shifting layers.
Skew-T
this link shows the wind directions changing -view the wind barbs along the right side of plot.

I do not understand what you mean by bending over. As for the weather over Mid TN, we are entering a wet period late week. Might even have some severe . The upper low over Georgia has a cold pool associated with it, and will enhance the normal summertime thunderstorms over our area. They will be slow movers and could cause some flooding.

Has there ever been a major outbreak in fall tornado season?
By major i mean with ef-4 tornadoes etc?
