Weather Synopsis - 11 April/12UTC to 12 April/12UTC 1998





Synoptic Situation:


High amplitude flow aloft continued, as the ridge of high
pressure built eastward into the Mississippi Valley and
Great Lakes region. A broad trough of low pressure was situated
over the western US, while another trough lingered  off the
East Coast. The jet stream continued to curved across the 
southern states.


At the surface, high pressure covered the eastern 2/3 of the
US. Cyclogenesis occurred over the western Dakotas , and a
weak frontal system was crossing the Rockies.


Weather Conditions:



No strong/severe convection was reported this period.


Precipitation was widespread across the western third
of the US, with amounts up to 0.5-1.0 inches reported
across southern California.


Light precipitation (less than 0.25 inch) was also
observed across the northern Plains and Great Lakes
regions.
