This Crazy Weather

We've been scratching our heads about the weather, haven't we?  A warm winter, with below-average precipitation and a spring that seems warmer than normal so far makes us wonder what this summer will bring. 

Here's what the Farmers' Almanac says about the rest of spring:

APRIL 2012: temperature 66° (3° above avg.); precipitation 5.5" (1" above avg.); Apr 1-2: Sunny, warm; Apr 3-10: Scattered t-storms, very warm; Apr 11-19: Scattered t-storms, warm; Apr 20-22: Sunny, cool; Apr 23-30: A few t-storms, cool.

MAY 2012: temperature 70° (1° below avg.); precipitation 4.5" (0.5" below avg.); May 1-5: Sunny, warm; May 6-11: T-storms, then sunny, cool; May 12-21: Rain, then sunny, quite pleasant; May 22-24: T-storms, warm; May 25-31: Scattered t-storms, seasonable.
