A very unstable airmass was able to sustain itself overnight across the region during the predawn hours of June 6th and this atmosphere continued into the afternoon hours as well.  A strong ridge of high pressure was noted across the Great Basin and this left the Four State Region under the influence of northwest flow aloft.  This type of flow typically can produce strong to severe thunderstorms, along with flash flooding when upper level disturbances move in this flow.
