More Wet May Weather in Store

 In the previous post I did on the 19th (click here) I discussed another period of precipitation starting as early as the 21st but with increasing likelihood for severe weather.  Unfortunately the severe part became a reality.  As far as rainfall, here is what fell this past 7 days ending this morning (28th)...


With the added precipitation during the past few weeks, there has been a dramatic change in the drought monitor.

Will this trend continue?  In the previous post I mentioned signals pointing to a wetter than average June.  Some of the signals have backed up a bit, but I'm still leaning for near or above normal rainfall for most locations.

For the near term, a cold high pressure system settling into the midwest will promote gulf moisture to return across west Texas and into the high plains.  A weak, but important disturbance aloft will intensify into the southwest U.S. and will help to produce several rounds of showers and thunderstorms over the weekend and into early next week.   The majority of the rainfall will likely be concentrated over the southern High Plains but with a fair amount into Kansas/Colorado. That developing system is denoted by the red X across the eastern Pacific with it's eventual track indicated by the red dotted line/arrow.



There may be a prolonged (3 to 5 days) break beginning mid-week. 

Here is an early look at how much rain "might" fall through late next week, with the majority falling through the 2nd of June.



More on the June and July outlook in the next post.
