Monday starts quiet, with highs across the South Plains ranging from the upper 80s to low 90s and light winds through the day. The shift comes as a storm system drops into the Southwest. It pulls a deep plume of Pacific moisture toward West Texas, picking up tropical moisture left over from Hurricane Polo as it tracks across Baja and northwestern Mexico.
For anyone in Lubbock planning outdoor work, yard projects, or weekend plans that stretch into early next week, Sunday is the window. Once Monday evening hits, the pattern flips from warm and dry to cooler and wet, according to KCBD's forecast. Farmers, event planners, and anyone with Monday travel on the South Plains should watch the timing closely, since the change arrives mid-day rather than overnight.
