Good morning bloggers,
Happy Labor Day! We are having another colorful sunrise this morning without any clouds in the sky. Why? A volcano erupted in Alaska on August 7th:
From Spaceweather.com http://spaceweather.com/:
VOLCANIC SUNSETS: Sky watchers across the USA and Europe have been reporting unusually colorful sunsets and sunrises. The cause appears to be the August 7th eruption of the Kasatochi volcano in Alaska. The volcano hurled a massive cloud of ash and sulfur dioxide into the stratosphere; high winds have since carried the aerosols over parts of the USA and Europe, producing widespread "volcanic sunsets."
Here is a picture I took last week. The orange color is being caused by the sun reflecting off of the ash in the stratosphere. Last night I watched the cirrus clouds illuminate first, and then the ash turned orange after the cirrus color faded, which indicated that the ash was in the stratophere above where most of our weather occurs in the troposphere:

Gustav is hugging the Louisiana coastline this morning. At 6:45 this morning they eye is just offshore of Grand Isle, LA with 115 mph winds with gusts to near 130 mph. New Orleans is not getting the brunt of the hurricane, and this seems very different than Katrina of three years ago. We will know the impact of Gustav on New Orleans within hours.
Tropical Storm Hanna is strengthening this morning and this is the next big concern to the east coast of the United States.
And, a cold front is approaching our region. As Gustav moves inland today, there will be an interaction with the cold front as the front gets absorbed into Gustav's circulation. Look below at the 00z GFS valid Tuesday morning:

Some of the computer models have tried to stall Gustav over northeastern Texas. But, I am not sold on this stalling solution yet. The farther west Gustav ends up, the better chance that we will have more of an impact. Missouri is likely going to get a deluge of rain, but Kansas City is still seemingly on the edge of this system. The combined effort of Gustav and the cold front may bring us a very fall like day on Wednesday with some rain and temperatures in the 50s.
We will be tracking these developments on NBC Action News Midday (11 AM), and then at 5, 6, and 10 PM tonight.
Have a great Labor Day!
