Weather Underground midday recap for Saturday, July 27, 2013.
Severe thunderstorms moved into the East on Saturday, while scattered
showers and thunderstorms persisted for the Western states. A low
pressure system over the Great Lakes continued to push a cold front
southeastward throughout the day. Warm and moist air from the Gulf of
Mexico continued to pour in ahead of this system, allowing for scattered
showers and thunderstorms to develop from the Northeast through the
Gulf states. Some of these storms have turned severe with strong winds
and large hail. Strong winds reported across North Carolina and
Tennessee have blown down multiple large trees. Heavy rainfall was also
reported with these storms, causing areas of flooding. Heaviest
precipitation was reported in Hickory, North Carolina with a mid-day
total of 5.20 inches of rain. Meanwhile, the northern side of this
system allowed for shower and thunderstorm activity to persist for the
Upper Midwest and across the Great Lakes. These storms have not turned
severe.
Out West, scattered showers and thunderstorms spread northward across
the Western states due to monsoonal moisture over the Southwest. These
storms increased chances of flooding across the deserts, thus, flood
warnings and advisories have been issued for much of Arizona and New
Mexico. To the north, higher pressure over the Northwestern corner of
the nation allowed for dry and warm conditions to continue. These
conditions increased fire danger from the Pacific Northwest through the
Northern Rockies.
