I pulled the apk and used apk manager to decompile. There are 2 folders named layout-v3 and layout-v4 both containing xmls called notification_expanded_layout.xml.
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout android:id="@id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent"

<TextView android:textColor="#ff000000" android:id="@id/NotificationTemperature" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="12.0dip" android:layout_marginTop="2.0dip" android:text="72" android:layout_below="@id/NotificationForecastImageView" android:layout_alignParentLeft="true" />

</RelativeLayout>
</RelativeLayout>
Edit the 5 instances where it says textColor="#ff000000" which is black to textColor="ffffffff" for white. Do this for the xmls in both of the folders.
Recompile and resign with apk manager and you now have a weatherbug elite with white text in the notification dropdown.
As stated before I do not own WeatherBug Elite and posting of paid apps is not allowed on this forum so I cannot make this available to download from this thread. If you have any questions feel free to pm me!
