KEY MESSAGE 2
A noticeable warmup is still on track for next week as overnight lows and daytime highs will be at least 10 degrees to as much as 20-25 degrees above normal inland, with the warmest days Wed/Thu. Upper ridging will be in place with nearly zonal flow Monday into Tuesday as a series of warm front pass through, with reinforcing ridging Wed/Thu. H8 temperatures on Wed should peak near 15C and may reach 17C-18C on Thu, with inland temperatures potentially reaching into the mid/upper 80s both days per blend of NBM 90th percentile and 00Z GFS/ECMWF MOS guidance. Inland areas will be the warmest as the low level flow remains southwest, while coastal areas will be cooler, but still well above normal levels, with a southerly sea breeze influenced flow.
A surface trough developing Tue/Wed afternoons, along with convergence with local sea breezes, may be the focus for showers and thunderstorms each afternoon and early evening, though chance PoP is confined to inland sections attm. Cold fropa later this week may be delayed until Thu night per latest ECMWF.
Friday is expected to be cooler behind the cold front, but with highs still reaching 75-80 inland.
A few daily record highs mat be tied or broken on Wed, as well as record high minimum temperatures Tue through Thu.
