This is the first week of May and there is double digit departures from normal temperatures east of the Mississippi.

The double digits west of the Mississippi is also accompanied by negative changes around Nebraska, Colorado, Kansas and Wyoming. The wider the change the greater the chance of turbulent storms.

And the UNISYS water vapor satellite below shows the accumulation of water vapor at the very spot where negative temperatures occur. That system also extends into Arizona where the temperatures moved into the negative category as well. Now these are negative changes, not negative temperatures.

The map below shows where the anticipated rain will occur and in the amounts expected.

Where this gets interesting is realizing how dry and hot Earth has actually become. 

Recently I noticed the water vapor of Earth is primarily accumulating over the oceans. The continents are very dry and absent of water vapor. This is a view from some very talented people that built this computer program. But, it shows the North Pole. The continents are mostly absent of water vapor.

So, the question is how can New York State be under a fire danger watch with all the turbulent storms they have been receiving? Drought is a long term emergency and doesn't end because a severe storm rolled through the area. 

The drought in New York State is early onset. It is only beginning. It is considered abnormally dry and summer hasn't arrived yet.

Greenland has clouds simply because it has a large ice sheet. The ice is melting and providing water vapor.

Interestingly, the Inter tropical Convergence Zone is repopulated with water vapor. There is a very clear division in northern water vapor and the tropical region. Interesting. There is somewhat of a Bermuda High in the Atlantic.

There is an injection of water vapor into the continental system just south of Hawaii.

There is also a huge circulation center south of Mexico. That's a bit unusual.
