MONTHLY SUMMARY	

The wetness of May continued through the first two-thirds of June with nearly all of the month's
rainfall in the first 20 days.  The first two-thirds of the month were also quite cool, with a
low of 44 on the 1st, then record low max temperatures on the 4th-5th as a developing East Coast
system brought heavy rains totaling 1.75".  Highs both days were only 56.  Temperatures finally
felt like summer during the final week, with highs reaching the 90s on the 24th-26th, the warmest
readings since the record heat in late April.  Temperatures were still below normal by 1 degree.
Many weather systems affected the area, the most substantial being the aforementioned East Coast
storm on the 4th-5th and another system on the 17th that brought tremendous thunderstorms and
severe flash floods to Pittsburgh, PA, before heading southeast and dumping 1.96" of rain within
24 hours on our backyard.  Flash flooding was reported to our SW around Keyser WV, where 3.60"
was reported.  Also, on the 9th, severe hail hit the southwest and northeast ends of the county.
