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.
