Still more rain & time to check the eclipse forecast

We had concerns late last week about going from drought to flooding and it's showing up in a handful of places. Western Kansas has been on the receiving end of tremendous spring rains to help ease drought. While it is not over yet, a steady diet of rain will continue to move toward western Kansas throughout the remainder of May. 

Meanwhile farther east, there have been some really nice rains, but it also hasn't covered very many areas. Just look at the examples below and consider for a moment how close Hutch and Pretty Prairie are geographically. There's not much distance between Haysville and Viola, but yet a big difference in total rain.

Here is a regional map showing rain in the last seven days across Kansas and surrounding areas. It is very nice to see the big rains across western Kansas heading into summer. But notice how north central Oklahoma and south central Kansas still have pockets of lower rain totals. Those areas will have a better chance of rain through midweek.


What's the trigger this week:

There's a slow moving low coming up from the desert southwest that's setting off the storm chances today. Rain (as it develops) is not going to move very fast because the winds at roughly 20,000 feet are only 10-25 mph. That's just incredible in mid-late May. 

Generally speaking, it looks like much of the area could be in the running for another 1-2 inches of rain (before the day is over Thursday)

As we move closer to Thursday/Friday, the upper low coming through the Plains weakens enough to not be much of a threat any longer. A little drier setup seems reasonable for our second to last weekend in May. 

Look to the lunar eclipse next week?
 
There will be a total lunar eclipse next Wednesday morning. The moon will just be hitting totality before it sets in the morning, so your window of opportunity for viewing is brief. Totality begins at 6:14 and for a good part of the area, the moon will go down around 6:17-6:20ish. 

As of this writing, our viewing may not be ideal. A chance for thunderstorms is in the forecast heading into Tuesday night, and any leftover clouds will hamper our chances.
