The Heat is on for the end of May 5/30

May's temperatures have been relatively mild, until now.

May's normal high temperatures range from 68 degrees at the beginning of May, to 77 degrees by the end of the month!

So far the majority of the month has been fairly typical, if not below average as far as high temperatures. We even saw a heavy frost just before the middle of the month, which is fairly normal but did cause a fair amount of damage to some plants and crops. Some areas even saw a second frost just last week.

Does it all of a sudden feel like summer?

So far conditions in the Valley haven't been extremely humid.

Dew points so far this week have fallen into the comfort range.

Take a look at this chart.

The dew point, or the temperature the air must reach to be saturated, has been in the 50's this week with the heat.

However we are expecting conditions to become a bit more humid as we head into the weekend, dew points will likely rise into the 60's.

That's when things start to get a little sticky.

So what's up with all of this heat?  Well we have two features contributing.

A Bermuda high has set up camp off of the eastern coast, and this has formed almost a blocking pattern, so it's prevent any systems from moving in to cool things off.

With that Bermuda high, warm humid conditions are being pumped up the east coast.

We had a warm front that lifted north of the area Tuesday, so we are sitting under the warm sector.

Warm southwesterly winds have been ushering in the heat.

However the associated storm system with that warm front has settled over the central US, and that has brought another round of severe weather.

Unfortunately that Bermuda high isn't allowing that storm system to move east very fast, so the severe weather in the plains and upper Midwest continues.

The severe weather hasn'tbeen confined to the Midwest, it extended to the Great Lakes and the northeast! These are two tornado snapshots from Tuesday night.

This week there has been:

16 tornadoes reported on Monday

34 tornadoes reported on Tuesday

27 tornadoes reported on Wednesday

13 tornadoes reported on Thursday

All of the reports are from the Storm Prediction Center, and is preliminary. So stay hydrated, keep the sunscreen handy, and relief is in sight for next week.
