1. Western United States:
COLD AIR REMAINS ENTRENCHED
Temperatures averaged 6°C to 12°C below normal across the Intermountain
West, with lows below -20°C dominating Montana and Wyoming. Weekly
departures of -3°C to -6°C covered the Great Basin, desert Southwest,
and High Plains, with readings plummeting below -10°C as far south
as northern Arizona. Meanwhile, highs of 20°C or higher were restricted
to California and southern Nevada, and the mercury failed to reach freezing
in southwestern Montana [COLD - 2 weeks].
2. Central United States:
WET WEATHER DOMINATES EASTERN PLAINS, BUT FAVORABLY DRY CONDITIONS
REPORTED FURTHER WEST
Moderate to heavy rain (50 to 150 mm) drenched northeastern Texas, eastern
Oklahoma, and parts of eastern Nebraska while 25 to 50 mm of precipitation
fell on central and southeastern Texas, central Oklahoma, eastern Kansas,
extreme eastern Nebraska, and most of Minnesota. In sharp contrast, fewer
than 25 mm of precipitation were observed across the High Plains. During
the last 8 weeks, precipitation totaled 100 to 400 mm, resulting in moisture
surpluses of 50 to locally 300 mm [WET - Up to 7 weeks].
3. Eastern United States:
DRYNESS DOMINATES
Fewer than 30 mm of rain fell on the Atlantic Seaboard from Florida northward
through Maryland while 10 to 50 mm dampened the Piedmont, the eastern foothills
of the Appalachians, and most of Pennsylvania. Although 8-week precipitation
totaled 50 to 150 mm, moisture deficits of 50 to 125 mm dominated the region
[DRY - Up to 7 weeks].
4. Southeastern Canada:
UNSEASONABLY MILD WEATHER PREVAILS
Temperatures averaged 3°C to 6°C above normal across southeastern
Canada, with weekly departures of +6°C to +8°C reported in western
Ontario and extreme northern Quebec. Highs exceeded 10°C across the
southern portion of the region while lows remained above -10°C at most
locations [WARM - Up to 5 weeks].
5. Central South America:
STILL UNUSUALLY WET
Moderate to heavy rains (25 to 100 mm) fell on north-central and extreme
northeastern Argentina, but only light precipitation (10 to 25 mm) was
observed in Uruguay and the remainder of northern Argentina. Since the
middle of September, 100 to 500 mm of rain has fallen on central South
America, allowing moisture surpluses of 50 to 300 mm to accumulate [WET
- Up to 9 weeks].
6. Western Europe:
STORMY WEATHER CONTINUES
A succession of Atlantic storm systems delivered 25 to 100 mm of precipitation
to southwestern Scandinavia, the British Isles, western and southern France,
and the northwestern half of the Iberian Peninsula, with heavy rains (100
to 200 mm) reported in southwestern France, northwestern Spain, northern
Portugal, and most of northern Italy. During the last 8 weeks, up to 800
mm of precipitation accumulated at some locations in the Alps and northern
Italy, resulting in excesses of 250 to 600 mm. Meanwhile, 100 to
500 mm of precipitation has fallen on the remainder of the region, yielding
moisture surpluses of 50 to 250 mm [WET - Up to 11 weeks].
7. Eastern Europe and North-Central Africa:
WARM ANOMALY DOMINATES REGION
Weekly departures of +2°C to +6°C covered most of eastern Europe,
with higher departures (+7°C to +8°C) reported around the Black
Sea and across western sections of the Commonwealth of Independent States
(CIS). The mercury climbed above 20°C as far north as the northern
shores of the Black Sea while highs reached above freezing across the entire
region. Lows remained above -10°C, with the mercury failing to reach
freezing across much of the western portions of the CIS. Meanwhile, temperatures
were 2°C to 5°C above normal in Tunisia and northern Libya, with
highs exceeding 30°C in most of northern Libya [WARM - Up to 8 weeks].
8. Southeastern Europe:
DRY CONDITIONS PREVAIL
Little or no rain fell on the region, except for 10 to 50 mm across central
and southern Ukraine, as the prolonged dry spell continued. During the
last 8 weeks, less than 150 mm of rain were measured, resulting in precipitation
shortfalls of 50 to 150 mm [DRY - Up to 15 weeks].
9. Eastern Siberia:
BITTER COLD GRIPS REGION
Extremely cold weather, characterized by weekly departures of -6°C
to -9°C, dominated eastern Siberia, where lows plummeted to -48°C.
In addition, the mercury failed to reach -20°C during the week [COLD
- Up to 5 weeks].
10. Southern Japan:
VERY WARM WEATHER CONTINUES
Weekly departures of +2°C to +3°C dominated the Ryukyus and the
coastal regions of southern Japan while departures of +3°C to +5°C
covered the interior mountains of the archipelago. Highs generally ranged
from 20°C to 25°C in southern Japan while readings of 25°C
to 29°C prevailed across the Ryukyus. The mercury stayed above freezing
across the southern half of Japan, with lows failing to reach 20°C
on the Ryukyus [WARM - Up to 22 weeks].
11. Southeastern China:
MODERATE RAINS CONTINUE
Moderate to heavy rains (50 to 100 mm) soaked south-central Guangdong,
northern Fujian, northeastern Jiangxi, and the northern and western portions
of Zhejiang while light to moderate precipitation (10 to 50 mm) prevailed
across the remainder of the region. Between 100 and 400 mm of rain has
fallen on southeastern China since the middle of September, allowing moisture
surpluses of 50 to 240 mm to accumulate [WET - Up to 10 weeks].
12. Eastern Australia:
MORE WET WEATHER
Torrential rains (100 to 200 mm) drenched several locations on the coast
of Queensland while moderate to heavy showers dumped 50 to 100 mm on eastern
and central Queensland, southeastern New South Wales, and northeastern
Victoria. Meanwhile, up to 50 mm of rain dampened western New South Wales
and western Queensland. In sharp contrast, little or no rain fell on interior
sections of New South Wales. Short-term moisture excesses of 100 to 200
mm were limited to southwestern and coastal Queensland while 8-week moisture
surpluses were less than 100 mm elsewhere [WET - Up to 7 weeks].
13. Northeastern Australia:
UNSEASONABLY COOL CONDITIONS REPORTED
Temperatures averaged 2°C to 4°C below normal across most of Queensland,
with lows falling below 20°C as far north as 20°S. The mercury
climbed above 30°C except along the coast of Queensland [COLD - 2 weeks].
