National Weather Summary for Thursday, August 6
NATIONAL WEATHER SUMMARY:
In the east, it was generally quiet to start the morning. By
afternoon, a cold front sparked off a few showers across the
Central Appalachians, but this only amounted to a few hundredths of
an inch of rainfall. A hot and humid airmass was in place from
Southern New England southward through the Atlantic Southeast.
Thunderstorms developed during the afternoon hours across the
Southeast and Mid-Atlantic. Dozens of hail and damaging wind
reports were noted from southern Alabama to Virginia. Hail up to
tennis ball size was reported near Portal, GA.
Across the central of the country, a large complex of showers and thunderstorms trekked southward through the early morning hours along the Central and Southern Mississippi Valley. The line produced some brief heavy downpours as well as a few reports of
strong wind gusts before diminishing to scattered shower activity
over the Louisiana and Mississippi border region. Another strong
area of storms moved through portions of South-Central Nebraska and
North-Central Kansas during the mid-morning producing a few reports
of wind damage to trees, and hail to an inch in diameter. Strong
clusters of thunderstorms moved across western Arkansas and
Oklahoma during the late afternoon and evening hours. For many
locations in Arkansas this was the second round of thunderstorms.
Jonesboro, AR noted a record rainfall of over two inches. A strong
line of thunderstorms were still producing hail up to an inch in
diameter across eastern Colorado overnight. Temperatures were below
normal across much of the Upper Midwest, while triple digits were
found across Texas and Oklahoma.
In the West, isolated showers and storms were found across mainly the higher terrain of the Northern Rockies. Most were not
severe, however, some stronger storms produced damaging wind gusts across Utah during the late afternoon and evening hours. A 64 mph gust was reported north of Callao, UT and a 78 mph gust near
Dugway, UT, both in Tooele County. Dry and hot conditions continued
to be found across much of the Southwest US, basking under a dome
of high pressure. Phoenix, AZ noted a record high minimum for the
