Pulling back the curtains this morning revealed a distant
CI anvil through a gap in an AS sheet to the WNW at
approx. 0700Z (thunder about?). The gap has since
filled in. Locally, the areas of undulating AC hint at
instability but no castellanus is evident at this time. The
sun is easily visible through a thin veil of AS. A few
spots of rain fell at 0825Z. Currently:
