WMS doesn't overlay correctly (4326)

My operational layer (wms wkid=4326) doesn't overlay correctly with the basemap below which is also in WGS84 (wkid=4326). See attached screenshot.

<map wraparound180="true" initialextent="126.987 37.066 127.060 37.098" fullextent="-179 -89 179 89" top="40">

Basemap:
<basemaps>
<layer label="Streets" type="tiled" visible="true"
url="http://server.arcgisonline.com/ArcGI...2D/MapServer"/>
</basemaps>

operational layer is:
<layer label="Weather" type="wms" visible="true" visiblelayers="LAND,BOUNDARIES,Present_Wx" FORMAT="image/png" alpha="0.8" styles="default"
url="https://somedomain.com/services/WMS?CRS=EPSG:4326" skipgetcapabilities="true" version="1.3.0" />

Any ideas? I am using the 3.0 FV.

Thanks.

Will
