$4M damage
What happened
A record cold arctic air mass overspread eastern West Virginia overnight on the 9th and 10th, dropping temperatures into the mid teens to lower 20s. These temperatures came on the heels of an above normal winter season. Warm temperatures in late March allowed apple and peach blossoms to reach critical bloom stage about 1 week ahead of schedule. Significant, but not total, kills of peaches and Red Delicious apples were noted. In general, the apple crop sustained 50 percent damage, but the peach crop kill range from 60 to 90 percent. Berries also sustained large kills.Some of the notable damaged acres included: Berkeley Co (WVZ052), 8500 acres; Hampshire Co (WVZ050), 4000 acres; Jefferson Co, 1700 acres.

Berkeley
3 injured
What happened
High pressure sat off the Mid-Atlantic coast from the 4th through the 7th, acting like a heat pump drawing in extremely warm and humid air. Temperatures on the 4th through early on the 7th were oppressively hot, and extremely humid conditions added to the misery. These conditions continued until a cold front swept through the area during the afternoon of the 7th, ushering cooler and much less humid air. The mercury soared into the upper 90s to lower 100s during the period. Dew points were in the lower to middle 70s, creating heat indices between 105 and 115 degrees. High temperatures on the 4th included 101 degrees at Berkeley Springs, 99 degrees at Keyser, 98 degrees at Romney and Charles Town, and 97 degrees at Mathias. Afternoon readings on the 5th included 103 degrees at Berkeley Springs, 101 degrees at Keyser, 100 degrees at Mathias, Moorefield, Charles Town, and Romney; 99 degrees at Martinsburg, and 98 degrees at Wardensville. Highs on the 6th included 102 degrees at Sugar Grove, 100 degrees at Charles Town, Martinsburg, Mathias, Moorefield, Romney, and Keyser; 98 degrees at Wardensville, and 96 degrees at Petersburg. Because of the 4th of July holiday weekend,...

Berkeley
$2.15M damage
What happened
A very dry month, containing one 7-day heat wave, exacerbated drought-like conditions across much of the fertile farmland of eastern West Virginia. The weather in July proved to be the death knell for much of the crop yields, including corn, hay, and pasture. The West Virginia Farm Service Agency reported the following damage statistics: Corn, hay, and pasture yields were 40 to 50 percent of normal. Estimated damage to the corn crop included 2500 to 3000 acres per county in the Potomac Highlands (WVZ048>051, 055) but as much as 10,000 acres in the eastern panhandle (WVZ052>053). Hay damage was estimated to be 40,000 acres per county; pasture land an additional 80,000 acres per county. No significant damage to alfalfa was noted. Though some summer fruit was damaged by the drought, most of what survived was excellent.
