NATIONAL STORM SUMMARY
JUNE 2012
1st-9th…Strong
storms and heavy rainfall developed across the eastern U.S. on Friday as a low
pressure system moved up the Ohio River Valley. This system created a warm front
that extended eastward and produced moderate to heavy showers and thunderstorms
across the Upper Ohio Valley and into the Northeast. At the same time, a cold
front stretched southward and produced strong storms through the Southeast. Some
of these storms turned severe with strong winds and large hail. Heaviest
rainfall fell over Boothville, Louisiana early Friday morning with a total of
2.88 inches of rain. Further south, strong thunderstorms and heavy rain showers
persisted over Florida. Flood watches have been issued for the southern tip of
Florida as the region has seen heavy rainfall for the past few days now.
Heaviest rainfall in Florida reached a mid-day total of 2.55 inches in
Hollywood, Florida. In the Plains, a weak trough of low pressure kicked up
widespread scattered showers and thunderstorms, but severe weather did not
develop across the Central and Northern Plains.
Rain
showers and high wind continued across the northern tier of the Northern
Intermountain West during the afternoon as the system progressed on Wednesday.
Prolonged and excessive precipitation maintained flood concerns throughout this
area. Meanwhile, the trailing cold front and waves of low pressure along the
front moved into the Northern Plains and Central High Plains. In the East, rain
and thunderstorms continued near a nearly stationary front extending from the
Central Gulf Coast through the Georgia Coast and into the Atlantic. Elsewhere in
the South, a slow moving low and plenty of moisture from the Gulf of Mexico
produced rain and thunderstorms in central Oklahoma and parts of northern Texas.
Rain
showers continued across the Deep South on Friday, as well as the Pacific
Northwest and Northern Rockies. However in the South, a frontal boundary stalled
over Florida and the Gulf Coast. This system produced more heavy rain showers
and strong thunderstorms from Florida through eastern Texas. Flash flooding
warnings have been issued for the Gulf Coast due to heavy rains persisting
across the region for the past few days. Rainfall totals on Friday ranged from 1
to 2.5 inches for most of the region, with heaviest rainfall reported in Conroe,
Texas with a mid-day total of 2.85 inches.
10th-16th…The
main weather system in the country was a long front that moved through the
Plains and Midwest on Monday. Deep moisture streamed northward from the Gulf of
Mexico and instigated strong thunderstorms and heavy rain from Iowa through
southern Illinois, Missouri, and northern Arkansas. Some of these thunderstorms
became severe and produced large, damaging hail in Missouri. No tornadoes were
reported as of mid-afternoon.
17th-23rd…In
the East, a cold front moved into the Northeast and Mid-Atlantic states from the
Midwest on Friday. This system pulled in moisture from the Atlantic Ocean and
produced scattered showers and thunderstorms throughout the day. Some of these
storms have turned severe with strong winds and large hail. Nickel to quarter
size hail was reported in Lenoir, North Carolina, while wind gusts up to 60 mph
were reported in Poland, Maine. Rainfall totals reached up to 1.74 inches in
Frenchville, Maine. In the Gulf of Mexico, a low pressure system brought more
heavy rains and scattered thunderstorms to the Yucatan Peninsula, western Cuba,
and southern Florida.
24th-30th…Tropical
Storm Debby remained the big weather story for the country Monday as it moved
very slowly toward the Florida Panhandle. The main problem associated with Debby
continued to be the significant rain and thunderstorms that it produced
throughout the Sunshine State. In addition to the up to 10 inches of rain that
fell on the state Sunday, an additional up to 5 inches of rain fell on the state
Monday. Rain will continue to fall while Debby remains in the eastern Gulf of
Mexico just south of the panhandle.
