Texas to Experience “Record Cold” Next Week — Solar Variability and Weather

The National Weather Service is warning of a brutal weekend cold front that will bring temperatures that “feel more like December!” to central and southern Texas, including San Antonio.

Maximum temps for Monday and Tuesday are forecast to be as low as 57F and 53F respectively — both would be new record low max temperatures, breaking San Antonio’s Oct 15 record of 64F set way back in 1896, and Oct 16 record low max of 61F set in 1912 (the Centennial Minimum).

The NWS adds that next week’s highs and lows will be close to San Antonio’s late December climate normals.

SOLAR VARIABILITY AND WEATHER

Research shows blocking persistence increases when solar activity is low, causing weather patterns to become locked in place at high and intermediate latitudes for prolonged periods of time.

During a solar minimum, the jet stream’s usual Zonal Flow (a west–east direction) reverts to more of a Meridional Flow (a north-south direction) — this is exaggerated further during a Grand Solar Minimum, like the one we’re entering now, and explains why regions become unseasonably hot or cold and others unusually dry or rainy, with the extremes lasting for an extended period of time.

The GSM is sinking arctic air further and further south.

Cold temperature records are tumbling and early snowpack is building.

Read here how the Grand Solar Minimum and resulting increase in Galactic Cosmic Rays are contributing to global cooling.
