1. Southern Alaska:
UNUSUALLY MILD WEATHER OVERSPREADS REGION
Temperatures were 2°C to 7°C above normal across the southern half
of Alaska, with weekly highs generally ranging from 5°C to 15°C.
The mercury remained above -10°C across the southern third of Alaska
[WARM - Up to 3 weeks].
2. South-Central Alaska:
VERY WET CONDITIONS PREVAIL
Weekly precipitation totaled 25 to 100 mm. During the last 4 weeks, precipitation
generally totaled 60 to 170 mm while almost 340 mm accumulated at Kodiak.
The 28-day totals were among the highest 10% of the climatological distribution
for the most recent 4-week period [WET - Up to 6 weeks].
3. Central Portions of Canada and the United States:
COLD AIR PUSHES SOUTHWARD
Unusually cold weather, characterized by weekly temperature departures
of -3°C to -7°C, dominated the central United States and the Prairie
Provinces of Canada. Subfreezing lows pushed as far south as northern Oklahoma
while lows of -10°C to -22°C prevailed across south-central Canada.
The mercury failed to reach the freezing mark in the northern portions
of Manitoba and Saskatchewan, but highs were in the twenties (°C) in
the central and southern United States [COLD - Up to 4 weeks].
4. South America:
ABOVE-NORMAL TEMPERATURES DOMINATE SOUTH AMERICA
Temperatures averaged 3°C to 6°C above normal from central Argentina
northward to central Brazil, but weekly departures ranged from +2°C
to +3°C further north. Highs soared above 40°C in northwestern
Argentina and western Paraguay while readings were in the thirties (°C)
across the remainder of the region. The mercury remained above freezing
north of 40°S, and did not fall below 20°C across much of northern
and central Brazil [WARM - Up to 5 weeks].
5. East-Central South America:
HEAVY RAINS PERSIST
Between 25 and 100 mm of rain fell on Uruguay and extreme southern Brazil
last week. Heavy rains since September 29th have dropped over 250 mm of
rain across western sections of Rio Grande Do Sul, the southern most state
of Brazil. This has resulted in 30-day totals of more than twice the climatological
average [WET - Up to 8 weeks].
6. Central Chile:
MORE VERY WET WEATHER
Moderate to heavy precipitation (50 to 200 mm) soaked central Chile. During
the 28 days, rainfall totals of 100 to 425 mm were among the highest 10%
of the climatological distribution for the given 4-week period [WET - Up
to 6 weeks].
7. Central Europe:
UNUSUALLY WET CONDITIONS DEVELOP
Weekly precipitation totals ranged from 25 to 100 mm, with locally higher
amounts approaching 200 mm at higher elevations in the Alps. Since late
August, 200 to 500 mm of precipitation has accumulated, yielding short-term
moisture surpluses of 50 to 260 mm [WET - Up to 7 weeks].
8. Northern and Central Europe:
COLD AIR DOMINATES EUROPE
Temperatures were 2°C to 4°C below normal across central Europe
while weekly departures of -3°C to -7°C dominated northern Europe.
Lows ranged from -10°C to -20°C across most of Scandinavia while
subfreezing lows dominated much of central Europe. The mercury failed to
reach 20°C throughout the region [COLD - Up to 3 weeks].
9. Southern Asia:
EXTENSIVE WARM ANOMALY REMAINS
Temperatures averaged 2°C to 4°C above normal across Asia from
eastern Turkey and central Saudi Arabia eastward to the Pacific Coast of
China. Locally higher departures (+5°C to +7°C) were reported in
central China and central Iran. Highs of 40°C to 44°C were reported
on parts of the Arabian Peninsula, southern Pakistan, and western India
while readings in the thirties (°C) dominated all of southern Asia.
The mercury reached 20°C as far north as southern Kazakhstan, northern
China, and southern Mongolia. Subfreezing lows were restricted to Kazakhstan
and the western and northern sections of China [WARM - Up to 7 weeks].
