1. Western United States:

ABOVE-NORMAL TEMPERATURES PREVAIL

Temperatures averaged 6°C to 11°C above normal across much of the Intermountain West while weekly departures of +2°C to +6°C covered most of the West Coast. Highs exceeded 30°C across the southern portions of California and Arizona while readings in the twenties (°C) reached as far north as north-central Nevada. The mercury remained above freezing along the West Coast while lows were generally above -10°C elsewhere [WARM - Up to 4 weeks].

2. Central and Eastern United States and Southeastern Canada:

DRY ANOMALY EXPANDS

Although 25 to 50 mm of precipitation fell on the southern Appalachians, most of the remaining United States east of the Rockies received little or none. The north-central states reported 13-week moisture deficits approaching 240 mm. During the last 4 weeks, fewer than 60 mm of precipitation fell on the eastern United States, with totals among the lowest 10% of the climatological distribution, as unusually dry conditions spread eastward [DRY - Up to 16 weeks].

3. Eastern United States:

COLD WEATHER BEGINS TO ABATE

Weekly departures ranged from -2°C to -4°C across most of the East, but temperature departures reached -5°C to -6°C in parts of New England and upstate New York. Lows of -20°C pushed as far south as central West Virginia while subfreezing lows penetrated to the Gulf Coast [COLD - Up to 3 weeks].

4. Colombia:

UNUSUALLY DRY CONDITIONS DEVELOP

Fewer than 25 mm of rain fell on Colombia during the last 4 weeks, with 28-day precipitation totals among the lowest 10% of the climatological distribution [DRY - Up to 6 weeks].

5. England:

WINTER STORM PARALYZES LONDON

The press reported that an unusual snow storm disrupted transportation and claimed at least one life in the vicinity of London, England. Although snowfall was less than 10 cm, such accumulations are generally very rare [Episodic Event].

6. Northern Scandinavia:

COLD AIR RETREATS FURTHER NORTHWARD

Weekly departures of -6°C to -15°C dominated the northern sections of Norway, Sweden, and Finland, with lows ranging from -20°C to -40°C. The mercury failed to reach -10°C across much of the region [COLD - Up to 6 weeks].

7. Mediterranean Basin:

WET ANOMALY DEVELOPS

Moderate to heavy rains (25 to 100 mm) soaked northern Tunisia, parts of Sicily, and most of Greece. During the last 4 weeks, rainfall totals (50 to 150 mm) were among the highest 10% of the climatological distribution [WET - Up to 5 weeks].

8. Southeastern Africa:

RAINS FALL ON NORTHERN ZIMBABWE; STILL VERY DRY ELSEWHERE

Between 25 and 100 mm of rain, with isolated heavier amounts to 200 mm brought welcome relief to northern Zimbabwe; however, rainfall totals diminished rapidly further south. Although 13-week precipitation totals ranged from 100 to 450 mm, substantial moisture deficits of 100 to 300 mm persisted across the region [DRY - Up to 14 weeks].

9. Southern China:

WARM ANOMALY WEAKENS

Temperatures were only 2°C to 3°C above normal during the past week. Highs were generally in the twenties (°C) while lows were generally above the freezing mark [WARM - Up to 4 weeks].

10. Southeastern Australia:

UNUSUALLY HIGH TEMPERATURES REPORTED

Temperatures averaged 2°C to 5°C above normal during the past week, with highs ranging from 36°C to 47°C [WARM - Up to 3 weeks].

11. Eastern Australia:

LARGE PRECIPITATION DEFICITS PERSIST

Light to moderate rains (10 to 100 mm) brought some relief to Victoria and Tasmania while light rain showers (10 to 50 mm) dampened northeastern New South Wales. Meanwhile, isolated showers delivered 10 to 50 mm of rain to parts of Queensland, but most of eastern Australia received little or none. Most of the interior received less than 100 mm of rain since November 3 while favored coastal locations measured up to 300 mm, yielding 13-week precipitation shortfalls of 50 to 150 mm across the interior and moisture shortages as high as 425 mm along the Queensland coast [DRY - Up to 19 weeks].
