New April rainfall maps

In the face of expanding drought across the Plains, we continue to see some encouraging signs going into April. Late March has been controlled by a dominant ridge of high pressure over the Southwest, and that has essentially led to more of what we had all winter (mild weather and several dry spells). Just look at all of the records that will fall on March 21st from California to Wisconsin.

Here's what happens around the 1st of the month:

Low pressure becomes favored over the area west of the Rockies while the high pressure moves to the East coast. As a word of caution - this doesn't always guarantee significant rainfall, but chances will return on a larger scale than anything we've had the past several weeks.

The rainfall outlook in early April looks like this:

This might make the difference between a mediocre wheat crop and one that could do very well, assuming we avoid all early spring freezes. I don't think the entire month will be rainy however, as high pressure may reassert itself back in the Plains by mid-late April.

If that becomes the case, we'll see our rain chances dropping off quickly and risks of severe weather will shift away from the central Plains.

In case you're wondering about temperatures, April should be warmer than average once again. I should remind you that even though we are having a hot start to spring, that doesn't necessarily mean the upcoming summer is going to be hotter than blazes. Some of the latest data continues to show the central Plains with an average or slightly cooler than average summer (months of June, July, and August combined). Some food for thought as we deal with the recent streak of record highs.

Thanks for reading!

Expanding drought - rain will be scarce

It's not that uncommon for March to be windy and mainly dry, but if you keep missing rains into April, you start to get a little nervous about it what it means going into summer. Lately, there has been some good rainfall in south central and eastern Kansas, but the latest drought map doesn't necessarily reflect that. In the short term, high pressure from Kansas to the West coast will keep the central Plains mostly void of decent moisture.

Beneficial rainfall (and some snow) will favor the northern Plains and areas east of Kansas, but the stubborn ridge will keep the central and southern Plains dry. We'll also see the potential of severe storms drop off.

If we stretch our rainfall forecast out to April 20th, it's a tough map to digest for areas across central and western Kansas where things have been pretty dry. It doesn't mean there won't be any rain, just that conditions will be drier than average. 

For what it's worth, we are quickly watching the La Nina in the Pacific fade away. The water has been slightly colder than average for the past several months (since last summer), but we are currently seeing the water warm up south of Hawaii. That is key to a change that should be coming as we move toward summer. Traditionally, with an onset of El Nino, the Plains can expect patterns that bring more favorable rainfall. It won't happen overnight or within a week, but a shift toward El Nino offers some hopeful signs of rain going forward (even if the spring isn't overly helpful).

This is how the water looked on December 1st:

And now, you'll see less "blue" colors along the Equator. We know the water is gradually warming, but an official declaration of El Nino won't come for several more months yet. 

I'll write something soon and go into more detail on the El Nino coming, but for now, just know that we are soon making the switch. 

Have a great day!
