NATIONAL WEATHER SUMMARY

SEPTEMBER 2006

1st-9th...The remnants of Ernesto were expected to bring more rain to
the Northeast on Sunday. While most flood watches and warnings expired,
wind advisories were still in effect. Another low-pressure system could
cause showers and thunderstorms in the northern Plains and the Upper
Midwest. The system was also expected to bring rain to the Mississippi
Valley, the Southern Plains and the Southern Rockies. Many areas in the
Far West were expected to see temperatures in the 80s and 90s, as was
the Gulf Coast. The Northeast should rise into the 60s and 70s, and the
Plains could see similar temperatures.
Rain swept through the Southeast Friday, while a cold front moved into
the Northern Plains and the Upper Midwest. The Southwest and Rocky
Mountains experienced scattered showers and thunderstorms, while severe
storms hit Utah. Some showers also crept into the Central and Southern
Plains. Highs hit the 80s in the Southern Plains, Mississippi Valley,
and portions of the Southwest. In the Northeast, Northwest and
California, highs were in the 70s. Temperatures in the Upper Midwest
and the central Rocky Mountains were in the 50s.

10th-16th...Steady rain fell from Nebraska to Iowa Sunday, while
thunderstorms hit the Tennessee Valley, Gulf Coast and parts of the
Southwest. Clouds lingered from Pennsylvania to New Jersey, but in the
West, skies were clear and temperatures were moderate. Along the
Northern California coast, fog lingered into the coastal valleys and
kept temperatures cooler than normal for early September.
Rain and thunderstorms affected much of the country's midsection
Tuesday, while scattered showers and storms hit the Gulf Coast. Out
West, light rain fell over the northern Plains. Rain spread from the
mid-Mississippi and western Ohio Valley to the Southern Plains. Some
strong storms produced hail that measured up to an inch and wind gusts.
Hail-producing storms also fired up in the Four Corners region. In the
Atlantic, Hurricane Florence remained a category 1 hurricane as it
passed near Bermuda. In addition, a tropical depression near the
Leeward Islands became the seventh named storm, Gordon,
Monday afternoon.
Showers and scattered thunderstorms affected much of the nation
Wednesday, including the Midwest to the Gulf Coast. Isolated showers
and thunderstorms in the Southwest produced severe storm and tornado
warnings. A storm pushed through the Ohio Valley and Great Lakes,
dumping rain in Michigan, Indiana and Ohio. Showers and thunderstorms
also hit the Appalachians, Southeast, Mid-Atlantic and eastern Gulf
Coast. Rain pushed into New England early in the day, but diminished by
late morning and the afternoon. Later, cooler air poured into the
Northeast and Great Lakes.

17th-23rd...Rain soaked the eastern half of the country and the
Northwest on Tuesday. Light to moderate rain spread across New England,
while scattered showers and thunderstorms developed throughout the
Mid-Atlantic and Southeast. Heavier thunderstorms fired up across the
eastern Gulf Coast states and extreme southern Texas. Cool temperatures
and light rains settled on the Upper Midwest, Great Lakes and ohio
Valley. High temperatures only climbed into the 40s and 50s. Out West,
light to moderate rain fell across much of the Northwest and caused
temperatures to drop into the 50s and lower 60s. The Southwest and
southern Great Plains were warm and dry.
A strong cold front finally pushed off the East Coast and left mostly
dry conditions from the Southeast to the Mid-Atlantic. An exception was
over Florida where showers and thunderstorms developed near the tail
end of the long cold front. Also, light showers continued in western
New England due to moist flow over Lake Ontario and Lake Erie. Behind
this cold front, cool air poured into New England and the Great Lakes
and produced afternoon temperatures in the 50s from North Dakota
through western New England. Dry conditions engrossed the Plains and
Mississippi Valley as a high pressure system sank southward from the
Northern Plains. The Southern Plains was the country's warmest region
with temperatures in the 80s. Elsewhere, a low pressure system moved
through the Great Basin and into the Rocky Mountains and provided the
nation's second early season snowstorm. Snow Advisories were in effect
for higher elevations of Utah and Colorado into the early evening as
several inches of snow fell in these regions. In the Northwest, another
Pacific storm pressed into the region and brought light rain showers in
the afternoon. This activity was expected to continue into the evening.
California experienced mostly dry conditions as high temperatures were
mainly in the 70s.

24th-30th...In the East, a cold front produced showers and
thunderstorms across the eastern Georgia, the eastern Carolinas, and
southeastern Virginia. Rainfall amounts have generally been light and
have been less than point-25 inches so far today. Another weak
disturbance produced light isolated showers across the Great Lakes,
though only trace amounts of rainfall was observed in the late morning
hours. Elsewhere across the East, high pressure provided for partly
cloudy skies and dry conditions. Low temperatures across the Great
Lakes, Ohio Valley, and the Northeast fell into the low to upper 40s.
Farther south, low temperatures across the Tennessee Valley and the
middle Atlantic were reported in the 50s and 60s. Across the Southeast,
low temperatures ranged from the upper 50s to the mid 70s from north to
south. Across the western two-thirds of the Nation, an upper-level
disturbance produced light isolated showers across the eastern portions
of the northern Plains as well as across the upper Mississippi Valley.
Farther south, surface high pressure provided for partly cloudy skies
and dry conditions across the rest of the Plains and the Mississippi
Valley. Further west, a strong upper-level ridge progressed eastward
also bringing mostly clear skies and dry conditions across the western
third of the Nation. Low temperatures across the central and northern
Plains, as well as the middle and upper Mississippi Valley ranged from
the upper 30s to the mid 40s. Across the southern Plains and the lower
Mississippi Valley, low temperatures were recorded in the upper 40s,
50s, and 60s. Lows across the Pacific Northwest, Great Basin, and the
central and northern Rockies were reported in the 20s, 30s, and 40s.
Temperatures fell into the 20s, 30s, and 40s across northeastern
California and Nevada, while just to the south, temperatures ranged
from the 50s, 60s, and 70s across southern California and Arizona.
Across the East, scattered showers and thunderstorms continued to move
across the Northeast. These storms produced occasional lightning
strikes, gusty winds, and moderate to heavy rainfall amounts. There
were many locations across the area that recorded up to a half of an
inch of rainfall or more. Barre, Vermont, recorded a rainfall amount of
1.45 inches while, Morrisville, Vermont, recorded a rainfall amount of
1.07 inches. Meanwhile, widely scattered light rain showers
were reported across the Great Lakes and the Ohio Valley. Rainfall
amounts with this activity was generally less then a tenth of an inch.
However an isolated storm moved across St. Marie, Michigan, producing a
rainfall amount of .47 inches. Elsewhere, skies were partly cloudy to
clear with dry conditions. Low
temperatures across the region were in the 40's and 50's across the
Northeast, the Middle Atlantic, Ohio Valley, the Tennessee Valley, and
the Southeast. Low temperatures across the Great Lakes were in the 30's
and 40's, while southern
Florida experienced lows in the 60's and 70's. Across the western
two-thirds of the United States, widely scattered light rain showers
continued to push across the northern Plains and the upper Mississippi
Valley. Rainfall amounts with this activity was generally less then
quarter of an inch. Roseau, Minnesota, recorded
one of the highest rainfall amounts with a total .28 inches. Meanwhile,
Scattered showers and thunderstorms ended across far southern Texas.
This activity produced occasional lightning, gusty winds, and locally
moderate rainfall amounts. Hebbronville, Texas recorded a rainfall
total of 0-point-55 inches. Elsewhere a large ridge of high pressure
brought partly cloudy skies with dry conditions to the Pacific
Northwest, much of California, the Great
Basin, the Desert Southwest, the Rockies, The middle Mississippi
Valley, the southern Mississippi Valley, the central Plains and
southern Plains. Low temperatures were in the 40's and 50's across the
Mississippi Valley and the Great Plains. Across the Rockies, the Great
Basin, and the Pacific Northwest low
temperatures were in the 30's and 40's. Across the Southwest low
temperatures were in the 60's and 70's while, low temperatures were in
the 50's and 60's across most of California.
