Weekly Global Climate Highlights Map for May 12, 2001

1. North-Central United States:

WET WEATHER EASES
Between 50 and 125 mm of rain soaked northern Missouri, southeastern Iowa, and parts of northern Illinois while 25 to 50 mm fell on a swath from eastern Nebraska northeastward to southeastern Wisconsin. Fewer than 25 mm of rain were reported elsewhere. Since the middle of March, 100 to 300 mm of precipitation has fallen on the region, yielding moisture surpluses of 50 to 180 mm [WET - Up to 8 weeks].

2. East-Central North America:

ABOVE-NORMAL TEMPERATURES DOMINATE
Weekly departures of +2°C to +6°C prevailed across the northeastern United States and the eastern half of Ontario while temperatures were 5°C to 9°C above normal across Quebec. Highs were generally in the twenties (°C) across the region, with the mercury soaring above 30°C along the Atlantic Seaboard and northern Appalachians. Subfreezing lows were restricted to Canada, New England, and some higher elevations in the Appalachians [WARM - Up to 3 weeks].

3. Eastern United States:

STILL VERY DRY
Scattered moderate showers (25 to 100 mm) dampened parts of northern Alabama, central sections of Tennessee and Kentucky, and the southern Appalachians; however, most of the East received little or none. During the past 8 weeks, precipitation deficits of 50 to 170 mm accumulated (see the United States Drought Monitor for complete details) [DRY - Up to 10 weeks].

4. Central and Southern South America:

COLD CONDITIONS PERSIST
Weekly departures of -2°C to -5°C dominated the region, with temperatures as much as 6°C below normal in southeastern Bolivia. Subfreezing lows were reported as far north as central San Luis and central Buenos Aires provinces of central Argentina while the mercury failed to reach 20°C across the southern half of the region [COLD - Up to 4 weeks].

5. Central Europe:

UNUSUALLY WARM CONDITIONS PREVAIL
Temperatures averaged 2°C to 3°C above normal, with weekly departures of +3°C to +5°C reported across the Baltic States, southern Sweden, and southeastern Norway. Highs exceeded 20°C across the entire region, but subfreezing lows were reported across southern Scandinavia [WARM - Up to 6 weeks].

6. Southeastern Europe:

LATE-SEASON MODERATE TO HEAVY RAINS REPORTED
Moderate to heavy showers dropped 25 to 100 mm of rain on most of Bulgaria, Greece, and northwestern Turkey. Precipitation totals ranged from 100 to 300 mm during the past 8 weeks, resulting in moisture surpluses of 50 to 120 mm [WET - Up to 8 weeks].

7. Mozambique:

DRY ANOMALY DEVELOPS
Little or no rain has fallen on much of Mozambique for the fourth consecutive week [DRY - Up to 4 weeks].

8. South-Central Asia:

WARM ANOMALY DEVELOPS
Weekly departures of +4°C to +9°C again prevailed over northern and eastern Pakistan while temperatures averaging 2°C to 5°C above normal dominated northwestern India.  The mercury soared into the middle to upper forties (°C) across the region [WARM - Up to 3 weeks].

9. Eastern Siberia:

WARMTH PERSISTS
Temperatures averaged 4°C to 5°C above normal in far eastern Siberia as highs reached 22°C at Yakutsk, Russia (62°N) [WARM - Up to 5 weeks].

10. Northern Japan:

COOL WEATHER CONTINUES
Relatively cool conditions continued over Japan's Hokkaido Island. Temperatures averaged 2°C to 3°C below normal, and the mercury dipped below freezing on parts of the island [COLD - Up to 3 weeks].

11. East-Central Asia:

SCATTERED SHOWERS BRING SOME RELIEF
Showers (20 to 40 mm) eased dryness across parts of South Korea and Honshu Island of Japan. Dry conditions, however, again prevailed over China's Hebei and Shandong Provinces. Despite the favorable rains, 8-week moisture deficits of 70 to 200 mm prevailed over much of the region [DRY - Up to 11 weeks].
