It has been an interesting July to say the least.  We started off with very warm temperatures, but a shift in the upper level pattern has caused us to have more rain in our forecast with cooler temps.

The jet has taken a dip, and brought changes with it

The jet stream, or the upper level highway of winds that drives our weather patterns has taken a unusual shape for this time of the year.  Normally the jet is more zonal, or west to east, and it typically up to the north more in southern Canada.  

We are going to see this pattern continuing again into Tuesday.  We will eventually see the trough start to shift east late week. 

To have a big ridge out west and a deep trough in the east is more typical of what we would see in the spring or the fall.  But since this is happening in summer it is bringing some crazy heat out west.

There was record heat from the mid-south to the south west today.  Record temperatures were recorded in many location in Texas during the day on Monday.  

In the desert southwest, temperatures are typically the most extreme that we see in the US, with numbers hotter than we have ever experienced in Ohio.  In fact, I posted a story last week about the heat out west, and how it was hotter at night than we have been in almost 60 years!

The heat is a problem out west, but in the east, it is rain!

These rainfall forecasts are on top of already record rains that dropped over the past few days.  We are seeing a weather system just churning up the east coast, tapping into plentiful moisture.

This pattern will continue through the next few days meaning the best chances of heavy rain in Ohio will be to the east, and the chances of heavier rain increase as you head to the east coast.

This pattern will continue and slowly slide up the east coast on Wednesday.

Looking forward the pattern is slow to shift.

We will see the flow flatten out a bit as we head later into the week.

As the pattern starts to flatten out a bit, the rain chances back at home will decrease a bit.

We will have a couple of weak boundaries that slide through later in the work week, and this will dry us out for the start of the weekend.

As we head into next week, another deep trough develops to the west, and this will bring a system up into our area early next week, followed by more chances of rain showers on the backside.

This means scattered showers will increase in coverage late in the weekend, and will remain in place for next work week.

The forecast for the end of July/early August does appear to be a bit more on the wet side.
