These two systems are spreading copious amounts of precipitation! North Miami Beach, Florida recorded 11.31 inches of rain yesterday, while 12+ […]

Hurricanes and the Calendar

  Though the six month Atlantic Hurricane Season ended 17 days ago, hurricanes and cyclones have little respect for the calendar. Even as Cyclone Laurence (photo) finally begins to weaken over the northwest coast of Australia (note the lack of organization with the clusters of thunderstorms) today, winds yesterday were in the 125mph category.

Central and Southeast Texas Weekly Weather Outlook:   Looks like we may be in for a few more surprise over the next week…First let me briefly talk about the upcoming snow burst.  Yes, it is probably going to snow based on the consistent nature of both the ETA and GFS.  I noticed the new data […]
