After some early week rain of less than 0.25 inches in most places with isolated totals to 0.50 inches in the far north and west part of the state, it will turn more seasonable in terms of temperatures but very little additional rainfall is forecast during the upcoming week.
It looks like the second half of May will be warmer than normal by several degrees with increasing chances for rain. However, most places will see 1-2 inches of rain which is still normal to a bit below normal.
Therefore, overall, May will go down as a warmer and slightly drier than normal month.
Looking ahead to summer, this appears to be an El Nino summer. The weak El Nino will continue and may strengthen some. El Nino will likely last into fall and possibly into 2016.
Typically, El Nino years push crop yields closer to trend line and summer weather can have stresses from temperature and precipitation swings.
