View from outer space of hurricane Marie from Astronaut Reid Wiseman (NASA)
Some amazing pictures and an amazing story of astronaut Reid Wiseman who is now at the International Space Station. Wiseman’s pictures have been nothing short of fantastic. The one from yesterday of hurricane Marie off the pacific coast is spectacular.

You can view all of Wiseman’s ‘tweets’ and pictures by viewing his Twitter account. Even if you are not a Twitter person these shots are worth seeing.

Climate Prediction Center seasonal outlook for November, December and January
National Weather Service computer models used by the Climate Prediction Center are now predicting a 78% chance of an El Nino by late fall. You can see the late fall outlook above with above average temperatures. This would correspond to an El Nino pattern across most of the United States. An El Nino weather pattern would cause most of the United States to see above average temperatures and below average precipitation. California and the southeast would be the exception because during El Nino years there is usually heavy rainfall. This is true across the southeastern U.S. as well.
This pattern persists because during these situations a strong west-east flow is created which is called a ‘zonal flow’. This pattern is generally a mild pattern as it brings warmer pacific air across much of the northern states.

The muggy meter gives you a quick idea on what it ‘feels like’ outside
As the August heat has reemerged this last week we are just beginning to deal with really humid days. We talk about a couple different factors when we forecast heat and humidity. The first factor is dew point. This is one of the variables that we use more in the weather center because it is much more scientifically accurate and represents the true nature of what the weather will be like.
What you need to know about the dew point is simply that any dew point temperature over 65° is considered uncomfortable. As the dew point rises it becomes more uncomfortable. A dew point of 70° can be very uncomfortable. This plays into the forecast for Tuesday. We are expecting only our third 90 degree day of the year. The dew point will be at 71° by afternoon. We combine the temperature and the dew point and we get the relative humidity.
Relative humidity is simply the humidity relative to the temperature. So for example our humidity tomorrow will be over 50%. While that doesn’t sound oppressive, if you say the dew point will be 71° you now have a very good idea that it will be very humid and rather uncomfortable by afternoon.
Why is high humidity uncomfortable to humans? Well, our body uses a system of cooling itself by evaporation of the sweat that we create when we are hot. If the dew point is over 65° then the evaporation rate slows down and there is an abundance of moisture that stays in the air and on your skin and your bodies cooling system does not work as well. That’s what we mean when we say it will be rather uncomfortable.

Flash Flood Warning this AM
There are flash flood warnings out this morning for heavy rainfall over 3 inches possible in just 2 to 3 hours. This heavy rainfall should begin to taper off by 9am this morning.

Biggest risk for gusty storm winds and large hail
Slight risk for severe weather
The Storm Prediction has put our area into the slight risk category for this afternoon and this evening. We are especially looking for gusty thunderstorm winds exceeding 60 mph and also some large hail. There is also a risk of tornadoes across western and central Indiana.
Satellite rainfall estimates from NOAA
One of the other problems will be just to our west and south as we could see heavy rainfall creating flash flooding. Rainfall rates could be up to 2″ an hour at times. This rainfall is moving in from Wisconsin and our area will be just to the east of this boundary this afternoon and evening.

So far just 2 90 degree days when we average almost 15 days per summer
For the first time in quite a while we have a legitimate chance of hitting 90 this weekend. If we do hit 90 on Saturday and Sunday it would be the first 90 degree or better day since June when we hit 93 on the 17th and 92 on the 18th. Otherwise it’s been a pretty cool summer. This pattern has started to change as higher humidity has been introduced in our forecast since last weekend.
After this weekend there is a slight chance we reach 90 on Monday or Tuesday, but the probabilities are lower. It really looks like upper 80s those days are more probable.

Biggest risks according to SPC are for damaging winds and hail
Slight risk area included all of northeast Indiana and NW Ohio
This is the area outlined by the Storm Prediction Center as having a risk for severe thunderstorms that produce mostly damaging thunderstorm winds up to 60 mph and large hail. The timing of this mostly through the early evening but we could see some storms late this afternoon as well. A front will move through the area tonight and ahead of it is where a boundary of storms may develop. These will be quick moving storms through early this evening and should end before midnight.
