3. Eastern United States:

A FAVORABLY DRY WEEK

In sharp contrast to previous weeks, little or no rain fell on the vast majority of the eastern states during the past seven days. Moderate to heavy rains (50 to 200 mm) soaked the Gulf Coast and parts of Florida while isolated showers delivered 25 to 100 mm to parts of the Carolinas. Between 400 and 800 mm of precipitation has accumulated during April, May, and June, yielding moisture excesses of 50 to 400 mm. By the end of the week, Tropical Storm Bill threatened the Gulf Coast of the United States [WET - Up to 15 weeks].

4. South America:

UNSEASONABLY WARM WEATHER PERSISTS

Weekly departures of +6°C to +9°C dominated Paraguay, northern Argentina, extreme southern Brazil, and western Uruguay while departures of +2°C to +6°C prevailed elsewhere. The mercury exceeded 30°C in Paraguay and interior portions of Brazil while highs were generally in the twenties (°C) elsewhere. The mercury remained above the freezing mark throughout the region [WARM - Up to 5 weeks].

5. Europe and Northern Africa:

STILL UNUSUALLY WARM

Temperatures averaged 6°C to 9°C above normal across southern Europe and parts of Algeria and Tunisia. Elsewhere, weekly departures ranged from +2°C to +6°C. Highs generally exceeded 30°C across the southern half of the region while readings soared above 40°C in Algeria and Tunisia. The mercury remained above 20°C throughout northern Africa [WARM - Up to 6 weeks].

6. Europe:

DRY CONDITIONS OVERSPREAD EUROPE

Fewer than 25 mm of rain were reported across the Continent, except for weekly totals of 25 to 100 mm in the Alps and the Urals. Four-week precipitation totals of less than 100 mm across Europe were among the lowest 10% of the climatological distribution [DRY - Up to 6 weeks].

7. European Russia:

STILL UNUSUALLY COOL

Temperatures averaged 2°C to 5°C below normal last week. The mercury failed to reach 30°C at most locations; however, readings remained above the freezing mark [COLD - Up to 4 weeks].

8. Western Siberia:

ABOVE-NORMAL TEMPERATURES PREVAIL

Weekly departures of +6°C to +9°C covered northwestern Siberia while weekly departures of +2°C to +6°C overspread the remainder of western Siberia. Highs for the week generally ranged from 20°C to 35°C [WARM - Up to 3 weeks].

9. Central Siberia:

UNUSUALLY COLD AIR SPREADS ACROSS REGION

Temperatures averaging 2°C to 6°C below normal overspread central Siberia, with locally larger negative temperature departures reaching -8°C near Lake Baykal. The mercury failed to reach 30°C while subfreezing lows reached as far south as the Mongolian border [COLD - 2 weeks].

10. Northeastern China and Southeastern Siberia:

PRECIPITATION DEFICITS REPORTED

Much of the area received fewer than 25 mm of rain last week, except for the far northwestern fringes, where weekly totals were as high as 100 mm. Eight-week precipitation shortfalls were as high as 150 mm in southeastern Siberia [DRY - Up to 7 weeks].

11. Indonesia and Southeastern Asia:

MODERATE TO HEAVY RAINS BRING RELIEF

Scattered moderate to heavy rain showers (50 to 200 mm) eased the unusually dry conditions across Indonesia and southeastern Asia; however, other locations received fewer than 50 mm of rain. Although 100 to 500 mm of rain accumulated during the last 8 weeks, precipitation shortfalls were as high as 400 mm [DRY - Ending at 10 weeks].

12. Southeastern Australia:

DRY ANOMALY DEVELOPS

Little or no rain fell on the region, except for a few scattered light to moderate showers (10 to 50 mm). Four-week precipitation totals of 105 mm or less were among the lowest 10% of the climatological distribution [DRY - Up to 6 weeks].
