Weather Synopsis - 10 April/12UTC to 11 April/12UTC 1998
Synoptic Situation: The flow aloft began to amplify this period, with a deep trough of low pressure along both the West and East Coast and a ridge of high pressure over the central US. The 110-130 knot jet stream remained situated across the southern states. At the surface, a trough lingered along the Pacific Northwest as a disorganized area of low pressure moved across the northern and central Rockies. High pressure covered the southern Plains and the Mississippi Valley regions. A trough exited the New England and Mid-Atlantic states, and was situated off the East Coast. Weather Conditions: Some strong convection was noted across parts of northeastern Oregon and southeastern Washington, with reports of hail up to 1.0 inch in diameter and wind gusts of 65 MPH. Precipitation across northern California, the Pacific Northwest, and the northern Rockies was generally light, but some 0.5-1.25 inch amounts were reported along the Washington and Oregon coast. Light precipitation (less than 0.25 inch) was also seen across the northern Plains, the Great Lakes, the central Appalachians, and the Mid-Atlantic regions.
