It seems like the downsloping northeasterly winds prevented it from dropping below 45F last night, even with clear skies. Full sunshine led to a quick warmup to a high of 62F before the northwesterly winds from the sea breeze became a bit too strong, with a maximum wind of 14 kt so far, higher than almost all models. This is quite the muted diurnal cycle compared to just a few miles farther inland, still in the city of Crescent City. Day 8 forecast will be similar to day 7, except that it will be warmer as the air mass warms further. Winds will be more easterly instead of northeasterly tonight and perhaps a bit stronger, leading to even more impediment to radiational cooling than last night, and lows likely above most model guidance. Like last night though, the caveat is the potential quick dips with brief periods of less wind or different wind direction, and there is more of a potential bust tonight with drier air. With the easterly offshore and downsloping winds, it will warm up quite quickly tomorrow, leading to a sharper and warmer temperature spike before the surface winds turn to northwesterly in the afternoon due to the sea breeze, causing it to cool down. This is a tricky high temperature forecast, and I suspect that it might actually get warmer than USL this time unlike day 7 due to the more easterly winds (and more resistance to sea breeze), but it’s hard to be confident in this city, and models disagree on exactly when the sea breeze wins out against the easterly winds at the surface. Again, northwesterly winds won’t be too strong due to the easterlies dominating just above the surface, though they could be a little stronger than models again, like today.
