Strong high pressure, some easterly or offshore winds, and clear skies, all the ingredients for a warm/hot day. The latest data suggest we could reach 82 here today. Even the overnight lows will be on the warm side, only falling to around 60. If you have to make a trip to the valley today, they are looking at the mid 90s this afternoon, and as for tonight, they only fall to the mid and upper 60s which could set some new record low temperatures, on the high side. They do have a Heat Advisory valid from noon today until 9pm tomorrow.
Speaking of tomorrow, we see a wind shift, so a weak onshore flow returns and helps cool us down some, tomorrow’s high around 76, the valley still in the mid and upper 90s as the onshore flow is not strong enough to influence their temperatures yet. Tomorrow night we may see some marine clouds trying to push in, the overnight lows now in the mid 50s.
Thursday the ridge drifts east and the onshore flow will become more dominate so we see more seasonable afternoon highs, still with mostly sunny skies, in the mid 60s. Thursday the valley also starts to cool down with afternoon highs in the low to mid 80s. With more of the marine clouds pushing in overnight, lows here and over in the valley should be in the low 50s.
As for the weekend, Friday on, we keep the weaker onshore flow which helps keep the afternoon temperature around the mid 60s, under mostly sunny skies still, and with mostly clear nights, nighttime lows remain in the low 50s.
Another reminder, you need to take extra precautions over the next couple of days. Remember to drink plenty of fluids, wear sunscreen if you are outside for any period of time, take plenty of breaks, wear light colored loose fitting clothing, and never leave pets, children or older relatives in your vehicle as the sun heats the inside of your vehicle to dangerous temperatures quickly, even with the windows down. It is also a good idea to check on your elderly friends and relatives in their homes during these hotter days as well.
Open fires are restricted in some areas so check with the local Fire District first. If you do have a fire, do no leave it unattended. The afternoon humidity levels will be dropping with the east winds kicking in later this morning or early afternoon, which only adds to the fire dangers.
