Warm Days and Mild Nights Early Week, Rain Chances and Colder Air Second Half of Week

Our mild early November pattern continues the next few days, but large scale north to south flow in the upper atmosphere will force polar air into the region by late week. There will be sufficient moisture and instability to give several days of scattered showers and thunderstorms, although no heavy rainfall is expected. Much colder air filters into the region Thursday night and persists through the weekend, meaning highs only in the lower 60 middle 60s with lows deep into the 40s. While the Atlantic Basin is devoid of tropical activity, in the Eastern Pacific Tropical Storm Xavier is generating heavy rainfall near Manzanillo. The storm will undergo significant wind shear as it moves northwest away from the coast, and it should dissipate by midweek.
