NATIONAL WEATHER SUMMARY
JUNE 2008
1st-7th…In the East, the low pressure system in the northern New
England lifted northeast Monday and produced mainly light in the
region through the morning hours. Otherwise, it was beautiful Monday
across much of the Northeast and northern Mid-Atlantic. The associated
cold front that extended southwestward across the Northeast coast and
Mid-Atlantic States pushed southeast and caused strong to severe
storms to develop across the Mid-Atlantic and portions of the
Southeast. Penny to quarter-sized hail pounded through Florida and the
Carolinas, with areas of high winds reaching above 60 mph. In the mid-
section of the nation, showers and thunderstorms continued from the
Northern and Central Plains eastward into portions of the Mississippi
Valley. This was due to a cold front over the Upper Midwest and a warm
front over the Central Plains and Mid-Mississippi Valley. Missouri and
Kansas were the focus for severe weather development. Large hail 2 to
4 inches in diameter and high damaging winds 60 to 70 mph swept
through the region. These dangerous storms caused large trees down,
which blocked roads, and some areas without power. Out West, moist
onshore flow kept much of the Pacific Northwest cloudy onday. On the
other hand, mostly clear skies prevailed across the rest of the West
Coast. Temperature wise, it was a fairly warm day across the nation
Monday. Afternoon temperatures climbed into the 60s and 70s mostly,
with the southern states in the 80s and 90s. Parts of Southern High
Plains and Desert Southwest saw temperatures soaring into triple
digits in the afternoon.
A low pressure system was stationed over the Central Plains for most
of today. The warm front associated with the system extended through
the Ohio Valley and into the Northeast and resulted in showers and
thunderstorms in the Central Plains, Ohio Valley, and the Northeast.
Some of the storms were severe, and there were hail and tornadoes
reported overnight and this morning throughout the Ohio Valley and
along the East Coast. These storms also caused flooding in the region.
Another front associated with the system extended into the Southeast
and brought scattered showers to the portions of the West. The Pacific
Northwest and the West Coast were dry with mild temperatures. A high
pressure system kept most of the South central and Southeast dry and
hot, with the exception of scattered thunderstorms in Florida. The
Northwest rose into the 60s, while the Southwest saw temperatures in
the 80s and 90s. The South central and Southeast rose into the 90s and
100s. The Central Plains were in the 80s and 90s, while the Northeast
ranged in the 50s up to the 70s.
8th-14th…Severe weather has swept through the Mississippi Valley and
the Ohio Valley Monday. The storms were triggered by a cold front that
extended southwestward from a low pressure system centered over Lake
Superior. Winds have been from the south for most of the day, so moist
Gulf air has made conditions favorable to produce heavy rainfall in
the region. A wide spread of hail has been reported with golf ball
size hail spotted in Jefferson County, Illinois. This system has also
brought strong winds to the region with 60 mph wind gusts reported in
central Indiana. The Southeast saw generally partly cloudy skies, with
the exception of Florida and portions of the Gulf Coast. These areas
have seen rain and thunderstorms Monday afternoon with strong winds
from the Atlantic Ocean at 60 mph reported in Orange County, Florida.
In the Northeast, a front kicked up some scattered showers over
northern New England. A high pressure ridge brought warmer air from
the south to the region, with temperatures in the 90s. Fredrick,
Maryland has reported 100 degrees. The Pacific Northwest has seen
scattered showers as a low pressure system off the west coast pushed
ashore. A thick cloud cover has brought overcast skies to most of the
region. The Southwest saw generally clear skies with warm temperatures
as the region was dominated by high pressure. Many areas of Arizona
have exceeded 100 degrees Monday.
Severe weather swept through the Northern Plains and Mississippi
Valley regions on Wednesday. These storms were associated with a warm
front that extended east of a low pressure system over the Central
Plains. The system pulled up moist and warm air from the Gulf, which
were favorable conditions for severe weather development. Nickel to
quarter-sized hail was reported in Steele, North Dakota and strong
winds with gusts up to 70 mph in Ashton, Iowa. In the Northeast and
Mid-Atlantic regions, a cold front passed through the region late
Tuesday night which put an end of 100 degree weather. However,
temperatures remained warm as high pressure dominated the area. In the
Southeast, afternoon scattered showers and thunderstorms popped up.
Penny-sized hail and strong winds have been reported in Northern
Florida. In the Pacific Northwest, high pressure off the coast
replaced the low pressure that swept through the region yesterday.
Thus, the rain ended and temperatures have started to warm up.
The Southwest saw hot and dry conditions as high pressure continued to
dominate the region.
15th-21st…Severe weather moved through the Northeast on Monday as a
cold front associated with a low pressure system up in Canada moved
through. These storms brought hail and damaging winds to the region.
Quarter sized hail was reported in Virginia, while Logan, New York
several car windshields were broken from the hail. Several trees were
reported down throughout the Northeast. The cold front extending from
the Northeast down through the Central Plains also produced
thunderstorms, some of which were severe, in the central part of the
country. The storms prompted several new flood warnings for the
already saturated plains. Also, there were several high wind and hail
reports, including hail at least one inch deep in Pawnee Rock, Kansas
and a home damaged by a tree that was blown over in Morehead,
Kentucky. The Southeast saw several pop-up thunderstorms on Monday as
moist Gulf air was pulled onshore to fuel the storms. Temperatures
were fairly warm, with highs getting into the high 80s and 90s. The
Northwest saw mostly clear skies on Monday as a result of high
pressure in the area. Temperatures were mild, with highs in the 50s
and 60s along the coast and 70s and mid 80s farther inland. A ridge
over the Southwest kept skies mostly clear and temperatures hot. Most
of the region reached temperatures at least in the 90s, while the
desert areas approached the 110s.
The stormy weather continued over the Front Range of the Rockies to
Texas around a bubble of heat in the Southwest. Eight tornadoes were
reported in eastern Colorado, while hail and damaging winds were
reported with the storms across the central to western Plains. A cold
front sweeping into the Midwest brought a return of showers and
thunderstorms to the flood-weary region. The storms were spotty, but
produced hail and gusty winds. A tornado was reported near Macedonia,
Iowa. The rainfall from the storms was not enough to exacerbate the
existent river flooding, but some areas had localized flash flooding
due to heavy downpours. Areas from Illinois to Missouri and Oklahoma
all experienced some trouble with flash flooding. The Gulf states were
also dealing with some heavy and strong storms with a surge of very
warm, moist air from the western Gulf coast. Hail and wind reports
were made over portions of Louisiana and southern Mississippi. Parts
of the Carolinas and Florida were also hit by locally drenching, gusty
storms that produced hail. Meanwhile, a cool, unsettled pocket of air
in the upper atmosphere continued to produce spotty showers and storms
over the Northeast. Temperatures were much warmer across the Ohio
Valley and mid-Atlantic with highs in the 70s and 80s. Some places
climbed by as much as 10 to 20 degrees from Thursday to Friday. The
rebounding warmth was nothing like the blazing heat of the Southwest,
however, where many more record highs were set. The deserts soared
past 115 degrees and places along the coast of California even reached
well into the 80s and 90s.
22nd-30th…Severe weather with damaging winds and large hail continued
across the eastern half of th US on Monday. A trough of low pressure
over the Northeast created a cold front that extended down the Ohio
Valley and into the Central Plains. The Southeast saw some severe
weather as a cold front moved through and triggered showers and
thunderstorms in the Carolinas. Meanwhile in Florida and the Gulf
states, afternoon showers and thunderstorms have popped up. Damaging
winds have been reported in Inglis, Florida. In the Northern Plains,
severe weather developed from a small trough of low pressure that
moved into the region on Wednesday. Hail was reported in Custer, South
Dakota. The Southern Plains saw calm conditions on Monday with patchy
clouds and warm weather. The Pacific Northwest saw showers on Monday
as a low pressure system off the West Coast brought scattered clouds
into the region. Temperatures remained seasonable with highs in the
60s along the coast and reached into the 70s inland. The Southwest
remained hot and dry with sunny conditions on Monday. Temperatures
were in the 90s and some desert areas approached 110 degrees.
Severe weather developed along the Gulf states on Wednesday. Reports
from these storms include golf ball size hail in southern Mississippi
and strong winds associated with a possible tornado on the Panhandle
of Florida. High pressure allowed for warm temperatures, while
southerly flow supplied abundant moisture. These conditions combined
produced thunderstorm development. A high pressure ridge dominated the
Northeast so the region saw patchy cloud cover and warm temperatures.
The Great Lakes saw severe weather on Wednesday triggered by a small
trough of low pressure that passed the region. Temperatures in these
regions have remained seasonable. The Southwest saw scattered clouds
which resulted from a moist flow that came up from the south. Few
areas experienced lightning and rain. Most of the rain evaporated
before it hit the ground, but some areas accumulated up to a tenth of
an inch. High pressure over California allowed for areas of smoke to
persist as a result of multiple continued fires across the state. The
Pacific Northwest saw warm temperatures and dry conditions on
Wednesday. A low pressure system to the north spread showers over
Canada, but showers did not reach the region.
Showers and thunderstorms have developed across the Ohio Valley with
showers across Virginia and into the Mid-Atlantic on Monday. More
numerous showers and thunderstorms move into the southern Gulf Coast
states and into northern Florida. Scattered showers and thunderstorms
will continue through the afternoon and evening across areas from the
Northeast, Ohio Valley, Mid-Atlantic, down through the Southeast and
into Florida. A few stronger storms will be possible with locally
heavy rainfall, large hail, occasional to frequent lightning and wind
gusts up to 50 mph possible. In the Central portion of the country,
mainly dry conditions were in place as high pressure held across the
region. However, showers with a few thunderstorms have already
occurred across areas of Texas and Louisiana with rainfall amounts of
over 0.50" already reported in areas of western Texas. Across the
West, mainly dry conditions have been in place with the exception of a
few isolated showers and storms across the Pacific Northwest and
Rockies. Scattered showers and thunderstorms will continue to be
possible across the Intermountain West, Rockies, Four Corners and the
Pacific Northwest as well as areas of the southern Four Corners
states. |
