The one week change in drought conditions from Isaac's rains are substantial and dramatic.
What a difference a week makes. The drought monitor as of this Monday shows a substantial decrease in drought severity across the Midwest, with more relief coming through the weekend. Thanks to the rainfall from Isaac, many areas picked up several inches of rain which have provided serious short-term relief. With a pattern change currently ongoing, wetter and cooler conditions should help continue to weaken the drought in both the Midwest and Plains through the next couple of weeks as storm tracks begin moving over the CONUS again.

It's not a typical tornado day, but the remnants of Isaac have an enviornment which is somewhat favorable for tornadoes to the S and E of the lows center.
While the atmosphere isn’t destabilizing fully, a tornado watch is in effect for E and SE Missouri into SW Illinois along with extreme NE Arkansas, Western Kentucky, and NW Tennessee. Thick clouds have limited the amount of sunshine these areas have gotten, but ample shear and ultra low cloud bases will yield a non-zero tornado threat in the region for the next several hours which bears some watching for local residents.

This image taken yesterday of the Wind Map on Hint.fm. You can clearly see Tropical Storm Isaac in the Southeast and a cold front working its way through the northern parts of the country. So cool!
Just found this site going around social media yesterday — the Wind Map. This site lets you see the wind speed conditions across the country and simply put: where air is moving. Hint.fm’s description is simple: “An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. ”
This map is super cool and updates with live weather conditions, so you can see the wind moving across America at any given point in the day. Pretty much, this is a pretty awesome site worthy of a daily visit.
Hurricane Isaac as illuminated by the moonlight as it approached landfall in Louisiana.
This is super cool.
This picture is the result of the moon illuminating the atmosphere and NASA’s Suomi’s Visible Infrared Imaging Radiometer Suite, VIIRS for short, imaging the atmosphere at different light wavelengths. The VIIRS images the earth from green to near infrared light frequencies, and with the help of light intensification (think electronic gain on cameras), this image was made possible [NASA Goddard]
Flooding rains forced hundreds of people to be rescued off of their roofs in Louisiana as Isaac moved ashore yesterday. This video from ABC news shows the flooding effects in the region, as up to (and possibly above) 20″ of rain is falling as Isaac continues to slowly lumber north and west over time. Simply a sad situation for many in flood prone areas in the region!
Tropical systems are a different beast from Great Plains supercells. Here are a few things to consider when intercepting.
With Issac just making landfall and Hurricane Season in full swing, I’ll be touching on how to forecast a tropical system, targeting the right area, and what to do while intercepting.
First off, forecasting a hurricane is just as difficult as trying to forecast a severe weather outbreak. While hurricanes are hundreds of miles across and there are computer models directly meant for tracking their path, any small variance in the atmosphere or in the ocean can drastically change the path and strength of the storm. When tracking a tropical system that is at least classified as a Tropical Depression (Not named, but has sustained winds between 35 and 39MPH), the National Hurricane Center will issue it’s projected 5 day track, which is a cone that extends out from the storm.
