Bay Area residents can expect a brief respite with warmer weather and clear skies today and Tuesday before a cooler, wet pattern rolls in later this week, according to the National Weather Service Bay Area. In a forecast that spoiled the April Fool's Day fun with facts, temperatures are anticipated to rise with inland valleys experiencing highs around 75 degrees, while coastal areas will see a mild 65.

The pleasant conditions are attributed to a high pressure system, which, according to the Area Forecast Discussion by NWS, "will bring clearing skies, modest onshore winds, and milder temperatures." However, the weather is set to do an about-face by Thursday. As a weather front moves in, heralding a trough from the northeast Pacific, conditions will become "cooler and damp," bringing the first rains of the month and below-seasonal average temperatures.

For mariners, a Small Craft Advisory was in effect until 9 AM PDT this morning for coastal areas from Pont Arena to Pont Reyes, marking a cautionary note for those taking to the seas. However, the winds are expected to subside and conditions improve somewhat into the early part of Tuesday.

Later in the week, "gusty northwest winds and rough seas" will pose challenges for marine activity, according to the Marine section of the Area Forecast Discussion. The rain forecast promises up to an inch for the more elevated regions like the Santa Cruz and Santa Lucia Mountains, and potentially higher totals if convection occurs. Despite the peaceful start, April may deliver its typical unpredictability, with another system possibly moving in early next week, ensuring the umbrellas won’t be stowed away for long.
