Winds from the southwest will range from 7 to 14 mph, with gusts up to 21 mph. There is a 60% chance of precipitation, with potential rainfall between a quarter and half an inch.

According to the forecast, the pattern of thunderstorms is set to continue into the night, with a 40% chance of rainfall before 1 a.m. and a slight possibility of showers thereafter. Temperatures are expected to dip to a low around 78 degrees. The weekend forecast indicates a 40% chance of showers and thunderstorms on Sunday, with highs nearly touching 90 degrees and similar conditions extending into Monday.
