1. Southwestern Alaska:

SUBNORMAL TEMPERATURES ABATE
Temperatures were within 3°C of normal across southwestern Alaska as bitterly cold weather eased. Lows still plummeted below -20° across the region, except along the immediate coast, but highs generally climbed above the freezing mark [COLD - Ending at 5 weeks].

2. Eastern Canada:

MILD WEATHER SHIFTS NORTHWARD
Weekly departures ranged from +6°C to +15°C across northeastern and east-central Canada, with highs climbing above -10°C from the Hudson Bay southward. Lows, however, still fell below -20°C, except in Labrador [WARM - Up to 14 weeks].

3. Buffalo, New York:

RECORD SNOWFALL BURIES CITY
Unusually severe lake effect snows inundated Buffalo, NY with up to 245 cm of snow between December 24 and December 28, setting a new all-time monthly record for snowfall. The 90 cm of snow during the 24 hours from 6 AM EST December 27 to 6 AM EST December 28 was the second highest 24-hour snowfall total on record, only exceeded by 96 cm on December 9-10, 1995. The heavy snow closed the airport and major highways for several days, and the National Guard was called up to assist in snow removal, according to the media. The extreme lake effect snowstorms followed Buffalo's first snowless November on record, and unusually low accumulation of only about 3 cm of snow during the first 23 days of December [Episodic Events].

4. Southeastern United States:

STILL UNUSUALLY DRY
Little or no precipitation fell on the southeastern United States during the past week, except for totals of 25 to 100 mm along the central Gulf Coast. Generally less than 150 mm of precipitation accumulated during the last 8 weeks, yielding short-term moisture deficits of 50 to 150 mm. Please see the United States Drought Monitor for more details [DRY - Up to 8 weeks].

5. Western and Southern Europe:

PRECIPITATION SHORTFALLS REMAIN
Between 10 and 50 mm of precipitation fell on the Benelux Countries, the northwestern half of France, and the Alps while little or none was reported across the remainder of the region. Precipitation totals for the last 13 weeks varied from 50 to 250 mm, resulting in shortfalls of 50 to 400 mm [DRY - Up to 15 weeks].

6. Europe:

BITTER COLD REMAINS
Temperatures were 3°C to 6°C below normal across the region, with locally larger departures in Finland (-15°C), Sweden (-13°C), Norway (-10°C), Former Yugoslavia (-10°C), and Spain (-10°C).

The mercury failed to reach freezing across Scandinavia and much of northeastern Europe [COLD - Up to 8 weeks].

7. Turkey and the Middle East:

MORE HEAVY PRECIPITATION
Torrential rains (100 to 200 mm) drenched the southern coast of Turkey while totals of 25 to 100 mm prevailed across the interior of Turkey and in northwestern Syria. During the last 13 weeks, most areas received 100 to 500 mm of rain, with isolated totals of 500 to 1225 mm reported. The large accumulations yielded 13-week moisture excesses of 100 to 300 mm [WET - Up to 11 weeks].

8. Western Africa:

HIGH TEMPERATURES DOMINATE
Temperatures averaged 4°C to 10°C above normal across the western Sahel from the Atlantic Coast of Senegal eastward to Burkina Faso, with highs soaring above 40°C across the interior of Senegal and in southwestern Mali, and reading in the thirties (°C) elsewhere. [WARM - Up to 4 weeks].

9. East-Central Africa:

DRYNESS SHIFTS NORTHWARD
Little or no rain fell on southern Kenya and northern Tanzania during the past week while 25 to 50 mm brought some relief to northern Madagascar. During the last 13 weeks, Kenya received fewer than 300 mm of rain, allowing moisture shortages to range from 50 to 160 mm while Madagascar logged 100 to 410 mm of rain, with shortfalls of 100 to 320 mm [DRY - Up to 12 weeks].

10. Southwestern Asia:

LARGE POSITIVE DEPARTURES REMAIN
Weekly departures ranged from +2°C to +7°C from the Arabian Peninsula eastward to western India. Highs were generally in the thirties (°C) across western India and in parts of Saudi Arabia, but readings remained below 30°C elsewhere. Subfreezing lows were limited to Iran [WARM - Up to 7 weeks].

11. Eastern Asia:

COLD ANOMALY ABATES
Subnormal temperatures, characterized by departures of -2°C to -6°C, prevailed across eastern China, but near- to above-normal temperatures prevailed to the north and west. Meanwhile, temperatures were 3°C to locally 19°C below normal across extreme eastern Siberia. Readings plummeted below -20°C as far south as west-central China, Manchuria, and Sakhalin Island while subfreezing lows penetrated as far south as 24°N. The thermometer failed to reach the freezing mark north of 40°C north across most of the region while readings remained below -20°C in eastern Siberia [COLD - Ending at 8 weeks].

12. Eastern China:

A FAVORABLY DRY WEEK
Little or no rain fell on the entire region, providing some relief from recent wet weather. During November and December, 100 to 400 mm of rain allowed short-term moisture surpluses of 50 to 200 mm to accumulate [WET - Up to 7 weeks].
