Good morning Central Coast, we have been talking about our incoming heatwave for what seems like a long time but today it begins.
High pressure is continuing to make for a hot forecast and continue to banish marine influence from the interior valleys. At the coasts there is some dense fog still lingering, that will keep temps significantly cooler by the coasts but it will still be slightly warmer than normal for this time of year.
Today's highs will climb quickly upwards of 100 in the interiors, 80s in the coastal valleys and 70s by the beach.
Starting at 10 a.m. today there is a heat advisory in place for all inland areas. This is not the most severe type of advisory for heat but it does indicate that people need to take precautions against it.
The heat advisory is only for Thursday into Friday morning. Friday morning through Monday an excessive heat warning is in place.
This is the most concerning part of the forecast where the daytime highs will range between 105 to 110 but the overnight lows are also quite warm. Not only is personal safety an issue during the heat wave but also elevated fire risk. That excessive heat warning drops Monday morning at 10:00 AM but a final advisory, and excessive heat watch, is in place from Monday morning through Monday evening.
The cause of the heat wave is a ridge of high pressure that is building from the four corners region back into the western United States. That Ridge of high pressure peaks on Friday and Saturday and so did the temperatures. Monday into Tuesday a trough of low pressure moves into the Pacific Northwest and weakens the Ridge and temperatures drop back into the middle 90s in the interior. for Tuesday and Wednesday. It appears though that another excessive heat event sets up later next week into the following weekend.
It is important to note that not everyone is covered in excessive heat. The dense fog that has prompted advisories several mornings this week is helping to keep cooler weather in play. That being said highs are still above normal for this time of year, just by much less of a margin than the interior valleys.
You'll find beaches generally in the 60s and lower 70s over the next several days with coastal valleys in the 70s to mid 80s.
With such severe heat taking over it is important to stay aware of heat related illnesses and dangers. Here is a look at a few things to look out for!
