8. Western Sahel:
HIGHLY VARIABLE RAINS REPORTED; ABOVE-NORMAL TEMPERATURES PREVAIL
Scattered thunderstorms dropped 50 to 200 mm of rain at some locations
while other areas received only 10 to 50 mm. Short-term moisture deficits
of 50 to 200 mm dominated the western Sahel [DRY - Up to 9 weeks]. Dry
conditions were aggravated by temperatures averaging 2°C to 4°C
above normal, with highs ranging from 35°C to 45°C. The mercury
remained above 20°C throughout the region [WARM - Up to 9 weeks].
9. Western Siberia:

northeastward to Shanghai, with weekly precipitation totals dropping rapidly
to the 10-50 mm range southeast and northwest of the aforementioned region.
Since the middle of May, 400 to 1100 mm of rain has accumulated, resulting
in short-term moisture surpluses of 100 to 400 mm, with locally higher
excesses to 600 mm [WET -Up to 8 weeks].
