Weekly Global Climate Highlights Map for April 5, 2003




1. Northwestern United States:

UNUSUALLY WET WEATHER DEVELOPS

Up to 200 mm of precipitation fell on the Pacific Northwest during the past week. Precipitation totals for the last 28 days, ranging from 60 to 410 mm, were among the highest 10% of the climatological distribution [WET - Up to 6 weeks].

 

2. North-Central United States:

DRY ANOMALY PERSISTS

Little or no precipitation fell on the Dakotas, Minnesota, Wisconsin, northeastern Nebraska, and northern Iowa last week. During the last 13 weeks, precipitation totaled less than 100 mm, resulting in moisture shortages of 50 to 105 mm [DRY - Up to 25 weeks].

 

3. East-Central United States:

WARM ANOMALY DEVELOPS

Weekly temperature departures of +2°C to +4°C prevailed across the central Appalachians and lower Midwest, with highs in the twenties (°C), but lows were generally below freezing. The warm anomaly may be short-lived as colder air began pushing into the region during the weekend [WARM - Up to 3 weeks].

 

4. Europe:

MOST OF EUROPE REMAINS DRY, BUT RELIEF COMES TO ALPS AND ITALY

Light precipitation, generally less than 25 mm, prevailed across much of Europe; however, 10 to 100 mm of precipitation fell on the Alps, Italy, Slovenia, and Croatia. Between February 9 and April 5, fewer than 200 mm of precipitation accumulated across the region, yielding shortfalls of 50 to 220 mm, with larger deficits (up to 430 mm) in Switzerland, Slovenia, and Croatia [DRY - Up to 10 weeks].

 

5. Western Europe:

WARM WEATHER ABATES

Temperatures were generally within 3°C of normal last week, with highs above 20°C in most of France and isolated parts of interior Great Britain. Lows hovered around the freezing mark across the region [WARM - Ending at 4 weeks].

 

6. Turkey:

STILL UNUSUALLY COLD

Temperatures were 2°C to 8°C below normal during the past week, with lows reaching -25°C in the mountains of northeastern Turkey. Despite the cold weather, highs generally exceeded 20°C [COLD - Up to 3 weeks].

 

7. Asia:

EXTENSIVE WARM ANOMALY PREVAILS

Temperatures averaged 2°C to 9°C above normal last week, with the largest departures (above +6°C) in Mongolia and interior parts of Siberia. The mercury climbed above the freezing mark as far north as 62°N while highs reached 20°C as far north as 43°N. Temperatures remained above freezing as far north as 40°N, but lows dropped below -20°C in most of Siberia [WARM - Up to 4 weeks].

 

8. Northeastern Australia:

MORE VERY DRY WEATHER

Little or no rain fell on most of Queensland, except for light to moderate showers (10 to 50 mm) on the eastern and southern fringes of the region. Eight-week precipitation amounts were as high as 410 mm, but short-term moisture deficits ranged from 50 to 700 mm, with larger deficts in coastal areas where heavy rain would be expected [DRY - Up to 10 weeks].
