U.S. Drought Monitor Report for the Week Ending Oct. 2 (Text)

Following is the text of the weekly U.S. Drought Monitor as released by the National Drought Mitigation Center in Lincoln, Nebraska:

Weekly Summary: During the past week, a slow-moving front sank
southeastward across the eastern two-thirds of the contiguous
United States.  A wave of low pressure formed along the front in
west-central Texas near the Edwards Plateau, resulting in
widespread heavy tropical rains for much of the southern Plains,
the lower Mississippi Valley, and the interior Southeast.  Heavy
rain (2 inches or greater) also fell over the Ohio and Tennessee
Valleys, southern Illinois, eastern Missouri, and the interior
mid-Atlantic region. The Upper Midwest, northern half of the
Great Plains, and the West received little to no precipitation
during the past 7-days. Temperatures for the period were
generally above normal in the West (as much as 8 degrees above
normal in the northern High Plains), 2-4 degrees below normal in
the  Great Lakes, Northeast, and Ohio Valley, and 2-4 degrees
above normal in the Southeast.

The Northeast and mid-Atlantic:  During the past week, most
areas received light to moderate rain (up to 2 inches), with
heavy rain (2 inches or greater) observed over  northern and
extreme southwestern Virginia, southwestern and south-central
Pennsylvania, southern West Virginia, and parts of New England.
Abnormally dry (D0) conditions were removed from West Virginia,
and from Fayette County in southwestern Pennsylvania. One-
category improvements were made in west-central and eastern New
York, and in parts of northern Virginia. For the southern
Delmarva Peninsula, Accomack, Somerset, and Worchester Counties
were upgraded from D1 to D0 based on AHPS Departure from Normal
Precipitation (DNP) at 180-, 90-, and 60-days.

The Ohio Valley:  Heavy rain (2 inches or greater) fell over
northern and eastern Ohio, southern Indiana, and much of
Kentucky.  Near to above-normal stream flows contributed to 1-
category upgrades across portions of the region. Louisville,
Kentucky’s 5.83 inches of rain resulted in their 9th wettest
September on record. In Ohio, D2 conditions were removed from
southwestern parts of the state, and trimmed back in south-
central portions of the state.

The Southeast: East-central Alabama, northern and western
Georgia, western portions of both North and South Carolina, and
Tennessee received in excess of 2 inches of rain during the past
week, prompting 1-category improvements to some areas,
especially across approximately the northwest half of Georgia.
Some of these locales in north-central and northeastern Georgia
received as much as 8 inches of rain.

The Upper Great Lakes and Midwest: Little if any precipitation
fell over Minnesota, Iowa, Wisconsin, Upper Michigan, northern
Illinois and portions of northern Missouri during the past 7-
days. Widespread 1-category degradations were made in the
region. Some of the more extensive changes involved expansion of
moderate drought (D1) conditions across northern Minnesota, and
much of north-central and northeastern Wisconsin.  Low stream
flows and 60-day DNPs lend support for these degradations. In
contrast, 1-category improvements were rendered to the drought
depiction over southern Illinois and eastern Missouri including
the St. Louis area.

The lower Mississippi/Delta area: Though Louisiana and
Mississippi received in excess of 2 inches of rain in
association with the low pressure area that developed over
Texas, the only alteration made at this time was to remove the
D3 designation over northwestern Mississippi.

The Northern Plains: Very dry weather continues to prevail
across the northern Great Plains, prompting extensive 1-category
downgrades across a large portion of North Dakota. Severe
drought (D2) was expanded to include most of the eastern half of
the state, and D2 was also expanded eastward across the Canadian
border counties as far east as Rolette County.  In the heart of
the state, D0 conditions were downgraded to D1. In South Dakota,
exceptional drought (D4) was expanded throughout the
southwestern portion of the state, and severe drought (D2) was
expanded throughout the northwestern portion of the state in
keeping with the prevailing dryness. These expansions also
pushed D4 and D2 conditions into eastern Wyoming and extreme
southeastern Montana, respectively.

The Central and Southern Plains:  The stalled front and
associated wave of low pressure that developed along it last
week brought beneficial, widespread rains to the southern Great
Plains. Many locations in Texas and in the southern half of
Oklahoma received heavy precipitation (2 inches or greater). As
a result, extensive 1-category upgrades were made to the
regional drought depiction. Significant runoff occurred for the
first time in over two years in west-central areas of Texas.  In
Oklahoma, 1-category improvements were made across much of the
state, including portions of the Panhandle, while D4 conditions
were expanded eastward across northern Oklahoma where little
rain fell this past week. Farther north in Kansas, a one-
category downgrade from D2 to D3 conditions was made across
northeastern and north-central sections of the state due to lack
of rain and surface water shortages. However, in eastern areas
of Kansas, one-category improvements were rendered to the
depiction due to recent rains and improved stream flows.

The Rockies:  The only revisions made this week were in
Colorado, where 1-category improvements were made to north-
central and extreme southeastern portions of the state.

The Southwest: No changes were made to the regional depiction
this week.

The Pacific Northwest: Abnormal dryness (D0) was expanded across
western portions of Oregon.  At this time, it appears that the
onset of the climatological rainy season will be delayed
somewhat.

Alaska, Hawaii, and Puerto Rico: One-category improvements were
made to northeastern portions of Oahu and Maui where respectable
rains fell (1.5 to 3.5 inches), and an expansion of D0
conditions was rendered to southwest portions of the Big Island
of Hawaii where little if any rain fell.  The depiction for both
Alaska and Puerto Rico remain unchanged at this time.

Looking Ahead:  In the ensuing 5 days, a fairly dry period is in
store for much of the lower 48 states. Exceptions would include
the eastern margin of the Eastern CONUS drought area, from
Arkansas northeast to New York, where 1-2 inches of rain is
expected, and also in North Dakota and far northern Minnesota,
where 1-2 inches of rain is predicted.

The CPC 6-10 day Precipitation Outlook projects elevated odds of
above-median precipitation from the eastern Great Lakes region,
the Northeast and mid-Atlantic southwestward to the Southwest,
as well as for most of Alaska (excluding the Panhandle). The
odds for below-median precipitation are enhanced across the
western Gulf Coast states including eastern Texas, the
northwestern quarter of the CONUS, and the Alaska Panhandle.
