As we head into tonight, skies will be partly cloudy. It does appear that the atmosphere will become favorable for the development of fog late tonight and early on Sunday Morning. Fog on Sunday could become a factor in how high temperatures climb. Anytime you get foggy days near the time of higher sun angles, usually the fog doesn't have a lasting impact and is short-lived. So I think it is reasonable to add a few degrees onto the MOS guidance which takes the city into the upper eighties with some areas flirting with 90. There is a weak disturbance that may spark an isolated thunderstorm in the afternoon and evening hours.
I am not anticipating a "washout" this week. However, any afternoon or evening could feature a scattering of thunderstorms and where they hit…there could be some localized heavy rainfall, gusty winds, and frequent lightning. It is very possible that some areas may not see much until Thursday and Friday of this week. With flash flood guidance still running low, despite a few days of dry weather, flash flooding remains a concern heading into this week.
