June, summer rain, and El Niño

Unofficial summer is here (meteorological summer), running June 1 - August 31st and I've been responding to many emails lately about the rain (or lack thereof) and the incoming super El Niño. Up until mid-May, there was great concern about when the rain would finally come. After all, I had been talking about a shift to "wetter" conditions with the incoming El Niño, but it just wasn't working out that way and week after week passed with no real change.

Let's look at how the water temperatures have changed since early May:

Now June:

The expansion of the warmer water to the west is quite impressive. On average, the water temperatures are .5°C warmer across the area that's monitored for El Nino (which happens to be more than 8 million square miles - mainly south of Hawaii)

And what we are seeing looking deeper into summer and early fall is even more drastic, with the likelihood of a strong El Nino shaping up. In fact, there's even some modeling that suggests this event might challenge the strongest El Nino on record (1997-98), which was one of the first episodes that was measured with satellite technology and studied more extensively.

Below is the 1997-98 El Nino

As we've said before, most strong El Niño patterns favor rain for Kansas. I've spent some time looking back at previous summers with this kind of influence and while not every month was wetter than average, more times than not rainfall was near or above average.

Here's the latest June outlook for rainfall:

And temperatures:

If we put the summer months (June, July, August) into one map, you get this kind of look:

Temperatures:

And rainfall:

I can (and will at some point) post some more images into the fall, but I continue to see signs of rain ahead, so drought will continue to scale back. It wouldn't be a total surprise if some areas of western Kansas fall out of drought altogether, but it will take more time for that to happen. 

Thanks for reading. I hope to have more timely updates this month. Please check back!
