Enjoy the sun today as clouds and rain chances move in for most of the upcoming week, including Christmas day. It will trend warmer through the week, with temperatures well above normal by mid to late week.
How about a gray Christmas instead of White? That is what we are looking at this year with mild temperatures in the 40s but cloudy with chances for rain through the day.
Heat miser has agreed to let go of the mild weather toward the end of December, with cold miser taking charge in January. Several chances of rain will accompany the warm air between Christmas and New Years Day. Colder air is expected to invade in January and likely continue through mid month at least, with some chances for snow during this colder period. Who wins after mid month is still being decided.
