Rain Moves Out And Fair Skies Move In! Also More Details On The 9.0 Japan Earthquake Shifting The Earths Axis Straight From NASA!

Well, bloggers you seen the cloudy / rainy skies across the area last night and through out the day today! Rainfall near three quarters of an inch in the Lafayette, area this afternoon. You can see the rest of the rainfall amounts in my last post.

The rain and cloudy skies will continue to push off to our northeast however not before a groggy start to tomorrow morning! Take a look at your morning commute forecast.
That's right bloggers be ready to start the day with some patchy fog possible. So allow some extra time to get where you need to be in the morning until this fog clears. Drive slow and remember your fog driving safety tips!

Well, the good news is this rain and low pressure system is moving out! You can see the low pressure system in this current surface image below.
Yes, that low pressre as well as the clouds and rain are gonna continue to push off to our northeast overtime. Which means dry weather over the next couple of days! Yes, I see some fair weather in the forecast with highs in the upper 60s maybe even the low 70s possible!
You can see the surface forecast for Wednesday (Tomorrow) above. We will see partly cloudy skies (aka) Fair weather across the area with highs in the upper 50s to low 60s possible! Just look at this awesome quick cast below.

Quick Cast.....

Wednesday we will look for partly cloudy skies across the area with a nice mild high around 59* degrees. However if we do in fact see more sun then clouds then I wouldn't be surprised to see a high in the low 60s! Expect a low Wednesday night around 42* degrees with light winds between 5 and 10 mph.

Thursday we will look for mostly cloudy skies through out the day with off and on peaks of sunshine. Expect a high around 68* near 70* degrees. A few scattered light rain showers around a 20% chance cannot be ruled out in some of our central and northern counties later that night into Friday. Expect a low around 54* degrees with winds between 10 and 15 mph. A few gusts to 20 - 25 mph possible.

Friday we will also be looking for highs in the middle 60s however I cannot totally rule out the chance for a few scattered hit and miss showers across the area. Still with highs in the 60s I think we can handle a little sprinkle! lol.

Now bloggers in one of my older post I talked about how the earthquake in Japan last Friday shifted the earth axis. Now I have a little more detail on that topic! The March 11, magnitude (upgraded to a 9.0 earthquake) in Japan may have shortened the length of each Earth day and shifted its axis. But don't worry—you won't notice the difference. I have more details about this event below straight from NASA! Take a look at what they have to say.

And remember you can send a $10 donation to Japan by texting REDCROSS to 90999. The $10 will be added to your next phone bill.

Or you can do what I did and buy a bracelet in which all money made goes to help Japan! Here's the site below where you can place your bracelet order. It's for a good cause!


Japan's Coastline Before and After the Tsunami

These images above show the effects of the tsunami on Japan's coastline. The image on the left was taken on Sept. 5, 2010; the image on the right was taken on March 12, 2011, one day after an earthquake and resulting tsunami struck the island nation.

Using a United States Geological Survey estimate for how the fault responsible for the earthquake slipped, research scientist Richard Gross of NASA's Jet Propulsion Laboratory, Pasadena, Calif., applied a complex model to perform a preliminary theoretical calculation of how the Japan earthquake—the fifth largest since 1900—affected Earth's rotation. His calculations indicate that by changing the distribution of Earth's mass, the Japanese earthquake should have caused Earth to rotate a bit faster, shortening the length of the day by about 1.8 microseconds (a microsecond is one millionth of a second).
The calculations also show the Japan quake should have shifted the position of Earth's figure axis (the axis about which Earth's mass is balanced) by about 17 centimeters (6.5 inches), towards 133 degrees east longitude. Earth's figure axis should not be confused with its north-south axis; they are offset by about 10 meters (about 33 feet). This shift in Earth's figure axis will cause Earth to wobble a bit differently as it rotates, but it will not cause a shift of Earth's axis in space—only external forces such as the gravitational attraction of the sun, moon and planets can do that.

Both calculations will likely change as data on the quake are further refined.
In comparison, following last year's magnitude 8.8 earthquake in Chile, Gross estimated the Chile quake should have shortened the length of day by about 1.26 microseconds and shifted Earth's figure axis by about 8 centimeters (3 inches). A similar calculation performed after the 2004 magnitude 9.1 Sumatran earthquake revealed it should have shortened the length of day by 6.8 microseconds and shifted Earth's figure axis by about 7 centimeters, or 2.76 inches. How an individual earthquake affects Earth's rotation depends on its size (magnitude), location and the details of how the fault slipped.

Gross said that, in theory, anything that redistributes Earth's mass will change Earth's rotation.

"Earth's rotation changes all the time as a result of not only earthquakes, but also the much larger effects of changes in atmospheric winds and oceanic currents," he said. "Over the course of a year, the length of the day increases and decreases by about a millisecond, or about 550 times larger than the change caused by the Japanese earthquake. The position of Earth's figure axis also changes all the time, by about 1 meter (3.3 feet) over the course of a year, or about six times more than the change that should have been caused by the Japan quake."
Gross said the changes in Earth's rotation and figure axis caused by earthquakes should not have any impacts on our daily lives. "These changes in Earth's rotation are perfectly natural and happen all the time," he said. "People shouldn't worry about them."

Well, they say it's  nothing to worry about! But Are you still a little worried? (Let me know in the comments please!).
