The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.

Don’t forget to take off those studded tires! Today April 1st is the deadline. The fine is pretty steep so get them off before you get caught.

An upper level high pressure ridge (shaded “Arch”shape) gave us plenty of sun and warm temperatures, but a low pressure area (shaded flattened out “Crescent” shape) that’s been sitting offshore is sliding eastward through California south of us giving us a chance of showers. A frontal system broke apart and slid south of us just like the last one did.
