1. South-Central United States:
COLD POCKET REMAINS
Weekly departures of -1°C to -2°C persisted across central and
eastern Texas while temperatures moderated across the rest of the South
and East. Highs exceeded 30°C in southeastern Texas and southern Louisiana
and reached 20°C elsewhere while lows remained above freezing [COLD
- Ending at 5 weeks].
2. Central United States:
ABNORMALLY WET WEATHER DOMINATES
Heavy thundershowers dumped more than 200 mm of rain on central and southern
Arkansas while moderate to heavy precipitation (50 to 200 mm) prevailed
across the central United States from the Gulf Coasts of Texas and Louisiana
northward to southern Lake Michigan. Meanwhile, lesser amounts (25 to 50
mm of rain) were observed on the fringes of the region. Between August
19 and October 13, the central states have received 100 to 525 mm of rain,
resulting in 8-week moisture excesses of 50 to 300 mm [WET - Up to 6 weeks].
3. New England and Nova Scotia:
DRY ANOMALY EXPANDS SOUTHWESTWARD
Little or no precipitation was reported across New England and Nova Scotia
during the past week as unusually dry conditions spread across northern
and central New England. Although 13-week moisture shortages ranged from
100 to 300 mm in Nova Scotia, precipitation deficits in New England were
generally less than 150 mm [DRY - Up to 17 weeks].
4. East-Central Argentina:
TORRENTIAL RAINS DRENCH AREA
Heavy downpours (100 to 200 mm) soaked extreme northern Buenos Aires, southern
Santa Fe, and most of Entre Rios provinces of east-central Argentina. Moderate
to heavy precipitation (25 to 100 mm) prevailed across the remainder of
the region. During the past 8 weeks, 100 to 400 mm of rain has fallen,
allowing short-term moisture excesses of 50 to 250 mm to accumulate [WET
- Up to 7 weeks].
5. Uruguay:
WARM ANOMALY ABATES
Temperatures were within 3°C of normal across Uruguay, but no subfreezing
lows were reported. Meanwhile, the mercury remained below 30°C at most
locations throughout the country [WARM - Ending at 4 weeks].
6. Central Europe:
MOISTURE SURPLUSES REMAIN
Little or no rain fell on central Europe from the Benelux Countries eastward
to western Poland and the Czech Republic. Further north, between 25 and
50 mm of rain was reported across Denmark. Precipitation totals since August
19 ranged from 100 to 560 mm, yielding short-term moisture surpluses of
50 to 250 mm [WET - Ending at 8 weeks].
7. East-Central China:
VERY DRY CONDITIONS PREVAIL
Moderate rains (25 to 50 mm) were limited to the Yangtze River Valley while
fewer than 25 mm were observed throughout the remainder of the region.
During the last 13 weeks, between 100 and 500 mm of precipitation has fallen,

8. Southern Australia:
LATE-SEASON COLD SNAP REPORTED
Temperatures averaged 2°C to 5°C below normal across southern Western
Australia and most of South Australia during the past week, with the largest
negative departures reported in central and south-central Western Australia.
The mercury failed to reach 30°C across the region, except at a few
locations along the extreme northern fringes, and readings stayed below
20°C in extreme southeastern South Australia. Meanwhile, lows reached
4°C as far north as Kalgoorlie (31°S) and 10°C as far north
as Alice Springs (24°S) [COLD - 2 weeks].
