Several factors can shift market odds for San Antonio's June 4 low. Updated seasonal climate forecasts and long-range weather models will influence expectations as the date approaches. Major weather pattern shifts, such as changes in jet stream positioning or tropical activity, can alter overnight temperature prospects.

Unusual heat waves or cold fronts in the weeks prior could reset baseline expectations.
