COLD CANADIAN AIR PENETRATES THE UNITED STATES
Bitterly cold air, with temperatures averaging 6°C to 12°C below
normal, overspread the Rockies and Great Plains while weekly departures
of -3°C to -6°C covered the remainder of the region. The mercury
plummeted below -20°C as far south as east-central Nevada and southern

freezing in the Rockies while highs above 20°C were restricted to southern
California and southeastern Arizona [COLD - Up to 3 weeks].

(8-week) precipitation totals ranged from 100 to 360 mm, with moisture
excesses ranging from 100 to 200 mm in the Red River Valley of the Dakotas

Up to 8 weeks].
3. Eastern United States:
MORE VERY DRY WEATHER
Fewer than 25 mm of rain was reported along the Atlantic Seaboard during
the past week. During the past 8 weeks, less than 150 mm of precipitation
has been measured, resulting in moisture deficits of 50 to 150 mm
[DRY - Up to 8 weeks].
4. Southeastern Canada:
MILD CONDITIONS DOMINATE
Temperatures averaged 3°C to 6°C below normal across Quebec and
the Canadian Maritimes, with lows remaining above freezing along the Atlantic
Coasts of Nova Scotia and southern Newfoundland. The mercury climbed above
10°C at many locations in the Maritimes [WARM - Up to 6 weeks].
5. Central South America:
COLD AIR OVERSPREADS REGION
Weekly departures of -3°C to -7°C prevailed across Bolivia, Paraguay,
parts of Uruguay, and most of Argentina, with subfreezing lows as far north
as northern La Pampa and central Mendoza provinces of central Argentina.
Despite the unusually low temperatures, highs pushed above 30°C at
most locations [COLD - 2 weeks].
6. Northern Argentina:
A RELATIVELY DRY WEEK
Scattered showers yielded 25 to 50 mm of rain in northern Argentina, but
most of the region received fewer than 25 mm. During the last 8 weeks,
50 to 650 mm of rain has fallen on the region, allowing moisture surpluses
of 50 to 225 mm to accumulate [WET - Up to 10 weeks].
7. Western and Southern Europe:
WET WEATHER PERSISTS IN ALPS, ABATES ELSEWHERE
Heavy precipitation (100 to 250 mm) inundated the Alps of Switzerland and
Italy while 50 to 100 mm fell on adjacent regions. In addition, northwestern
Spain and parts of eastern and western France received 50 to 100 mm of
rain. The remainder of western and central Europe reported precipitation
totals of 10 to 50 mm. During the past 8 weeks, 300 to 1100 mm of precipitation
has fallen on the Alps, yielding moisture excesses of 350 to 720 mm while
8-week totals of up to 400 mm and departures of up to 300 mm prevailed
elsewhere [WET - Up to 12 weeks].
8. Eastern Europe:
STILL UNSEASONABLY MILD
Weekly departures of +6°C to +11°C dominated northern Scandinavia
and interior portions of the Balkans while readings were 3°C to 6°C
above normal elsewhere. Lows remained above -10°C throughout eastern
Europe, with readings failing to reach freezing at many locations along
the Baltic Sea. The mercury soared past 20°C as far north as Hungary
and climbed above freezing across the entire region [WARM - Up to 9 weeks].
9. Southeastern Europe:
VERY DRY WEATHER CONTINUES
In sharp contrast to western and central Europe (Item 7 above), little
or no precipitation fell on southeastern Europe. Since late September,
less than 150 mm of rain has fallen on the region, allowing moisture deficits
of 50 to 150 mm to accumulate [DRY - Up to 16 weeks].
10. Southeastern Africa:
HEAVY RAINS DRENCH ZIMBABWE
Between 50 and 200 mm of rain soaked northern and eastern Zimbabwe while
10 to 50 mm fell on the remaining portions of the country. [WET - Up to
6 weeks].
11. Southern Siberia:
BITTERLY COLD WEATHER DOMINATES
Temperatures averaged 6°C to 10°C below normal across northern

the region while highs remained below freezing throughout the week [COLD
- Up to 6 weeks].
12. East-Central China:
SIBERIAN AIR MASS PUSHES SOUTHWARD
Cold weather, characterized by weekly departures of -2°C to -6°C,
dominated east-central China. Subfreezing lows penetrated as far south
as 30°N while the mercury approached -10°C across the northern
fringes of the region. Readings remained below 20°C at most locations
north of 30°N [COLD - 2 weeks].
13. Southeastern China:
LIGHT TO MODERATE RAINS REPORTED
Moderate precipitation (25 to 50 mm) fell on northern Jiangxi, northern
Hunan, eastern Henan, northern and eastern Anhui, Jiangsu, and Shanghai
while only light rains (10 to 25 mm) were measured elsewhere. Between September
24 and November 18, 100 to 400 mm of rain has fallen on the region, yielding
moisture surpluses of 50 to 250 mm [WET - Up to 11 weeks].
14. Southern Japan:
WARM ANOMALY ABATES
Temperatures averaged 1°C to 3°C above normal, with locally higher
departures approaching +4°C. The mercury remained above freezing at
