SUMMARY:

May 2006 goes down as the 4th driest, but was only .19" from being the driest in 15 years
of records.  The spring of 2006 was the driest spring on record with 7.00" rainfall.
Temperatures were near normal, but varied quite a bit.  The first 10 days were mild and
dry.  A slow-moving trough brought two weeks of cool, showery weather.  87% of the month's
rain fell from the 11th-15th.  After an unusually late frost on the 23rd, the temperature
made a spectacular recovery into the mid-90s on Memorial Day Weekend, with the 94 F
readings on the 29th and 30th just 2 degrees shy of the May record of 96 on May 19, 1996.
