Wet weather pattern likely over

Our six week series of storm systems, bringing nearly five inches of rain to Austin this month, appears to be over.  A shift in the the storm track is expected to result in a more typical La Nina pattern–warmer and drier-than-average weather–into mid-January.

The simplest definition of a storm track is a region where cyclones – swirling atmospheric eddies that average about 600 miles in diameter – travel frequently. During winter in the Northern Hemisphere midlatitudes, cyclones are an important component of day-to-day weather variability. In the broader climate system, cyclones are an important mechanism for distributing heat and moisture across latitudes from the tropics towards the poles, as well as from relatively warm ocean waters to the atmosphere during winter.

An Earth Gauge fact sheet discusses the primary source regions for Northern Hemisphere midlatitude cyclones and summarizes some focus areas in storm track research, including topography and Midwinter Storm Track Suppression, and global intensification of storm tracks.

    Y’all didn’t predict the onset of the drought. Y’all didn’t predict the last 6 weeks of rain. Why should I believe this latest forecast? Y’all aren’t making this up as you go along are you?
