1. Southern Alaska:
DRY ANOMALY DEVELOPS
Little or no precipitation has fallen on southwestern and south-central
Alaska during the last 7 weeks, and only 25 to 50 mm were reported during
mid-October. Precipitation shortfalls for the last 8 weeks ranged from
50 to 240 mm [DRY - Up to 7 weeks].
2. Alaska and Northwestern Canada:
ARCTIC AIR COVERS REGION
Large negative weekly temperature departures (-6°C to -13°C) dominated
central and southern Alaska and most of the Yukon Territory of Canada while
readings were 2°C to 6°C below normal elsewhere. Lows ranged from
-41°C to -20°C across the interior portions of Alaska and northwestern
Canada, and subfreezing lows prevailed across the remainder of the region.
The mercury failed to reach -20°C in central Alaska, and broke freezing
only along the immediate coasts [COLD - 2 weeks].
3. Eastern North America:
MORE UNUSUALLY MILD WEATHER
Temperatures averaging 6°C to 13°C above normal dominated the eastern
United States and southern Canada during the past week as very mild conditions
persisted. The mercury remained above freezing as far north as northern
Kentucky, and failed to reach -20°C throughout the region. Highs in
the twenties (°C) dominated the United States and southern Ontario
while the mercury climbed above the freezing mark throughout southeastern
Canada [DRY - Up to 11 weeks].
4. Eastern United States:
VERY DRY CONDITIONS DOMINATE
Little or no precipitation fell on most of the region, with totals of 10
to 25 mm restricted to the Appalachians and the mid-Atlantic. Precipitation
totals during the last 8 weeks were generally less than 125 mm, yielding
short-term moisture deficits of 50 to 200 mm. Please see the United
States Drought Monitor for more details [WARM - Up to 8 weeks].
5. Central South America:
ABNORMALLY COOL WEATHER PREVAILS
Weekly departures of -2°C to -5°C, with locally higher departures
to -7°C, covered much of central South America from eastern Bolivia
southward to central Argentina. The mercury dropped below 10°C as far
north as Rocha, Uruguay (35°S), but readings climbed above 30°C
across the region except in eastern and southern Uruguay and eastern Buenos
Aires Province of Argentina [COLD - 2 weeks].
6. Uruguay and Adjacent Argentina:
RAINFALL CONTINUES TO ABATE
Between 25 and 50 mm of rain dampened central and southern Uruguay and
eastern Buenos Aires Province of Argentina, with 50 to 100 mm reported
in northeastern Uruguay. Little or no rain was reported elsewhere. During
the last 13 weeks, 300 to 600 mm of rain have fallen on the region, allowing
moisture surpluses of 100 to 240 mm to persist [WET - Ending at 15 weeks].
7. Iberian Peninsula:
DRYNESS PERSISTS
Little or no rain fell on the Iberian Peninsula again last week. Total
precipitation during the last 3 months ranged from 50 to 400 mm, allowing
moisture deficits of 50 to 350 mm to accumulate [DRY - Up to 12 weeks].
8. Eastern Europe:
STILL ABNORMALLY COLD
Weekly departures of -2°C to -8°C dominated eastern Europe as Arctic
air bulged westward into Poland and the Balkans. The mercury plummeted
below -20°C in western Ukraine and fell below -10°C as far south
as Bulgaria. Subfreezing lows dominated the remainder of the region, except
for Greece. Readings failed to reach the freezing mark in eastern Poland
and Ukraine [COLD - Up to 5 weeks].
9. Turkey:
UNUSUALLY WET WEATHER PREVAILS ACROSS SOUTHERN TURKEY
Moderate precipitation fell on much of the southern half of Turkey, with
torrential rains (more than 100 mm) reported along the southern Mediterranean
Coast. Between October 14 and December 8, southern Turkey has received
100 to 400 mm of rain, resulting in short-term moisture surpluses of 50
to 200 mm [WET - Up to 8 weeks].
10. Southern Africa:
HEAVY RAINS PELT ZIMBABWE; FAVORABLY DRY ELSEWHERE
Heavy rains (50 to 200 mm) drenched the northeastern quadrant of Zimbabwe
while 25 to 100 mm fell on the remainder of the country. The rest of the
region received fewer than 50 mm of rain. During the last 8 weeks, precipitation
totaled 100 to 430 mm, yielding short-term moisture excesses of 50 to 220
mm [WET - Up to 10 weeks].
11. Asia:
COLD AIR SPREADS ACROSS CENTRAL ASIA
Bitterly cold Arctic air, characterized by weekly departures of -2°C
to -9°C, overspread central Asia from western Kazakhstan eastward to
eastern Mongolia. The mercury plummeted below -20°C across northern
Kazakhstan, most of Mongolia, and extreme northern China. Readings failed
to reach the freezing mark across the entire depicted region [COLD - 2
weeks].
12. Northern Japan:
COLD ANOMALY DEVELOPS
Temperatures were 2°C to 5°C below normal across Hokkaido and northern
Honshu, with subfreezing lows dominating the region [COLD - 2 weeks].
13. Southern and Western Australia:
UNSEASONABLY COOL CONDITIONS PERSIST
Temperatures averaged 2°C to 4°C below normal across much of the
region as unusually cool weather continued. The mercury dipped below 10°C
as far north as Kalgoorlie (31°S). Highs were generally in the thirties
(°C) across the interior regions and in the twenties (°C) along
the coast [COLD - Up to 10 weeks].
