FORECAST IN DETAIL

We’re much colder today, and we may even see a few snowflakes tonight. But it doesn’t look like the big red dude is bringing us a white Christmas. For Christmas Day the story is the cold plus gusty winds, with temperatures struggling to make it out of the 30s tomorrow through the weekend.

Today (Christmas Eve): We’re likely to squeeze in partly sunny skies this morning, as one system moves away and another approaches. Clouds thicken up again midday into the afternoon, holding highs to the more seasonable mid-40s, with a light breeze turning more from the east during the afternoon. We’ll also watch for a 30% chance of light rain showers as you start Christmas Eve dinner. Confidence: Medium-High

Tonight: The radar will be tracking more than Santa with a decent chance (60%) of some light showers during the evening and early overnight. We could see some snowflakes mix in by late evening, with a dusting not impossible as temperatures drop. Winds pick up overnight, ushering in much colder air, as lows range from the upper 20s in our cooler suburbs to around freezing downtown. Confidence: Medium

Tomorrow (Christmas Day): It’s a good day to spend inside with the family, that’s for sure! Cold, arctic air moves in and combined with a whipping wind, much of the day feels like the teens and 20s. In reality, afternoon highs reach the upper 30s to near 40 with plenty of sun. Winds gust 30-40 mph, so be sure to secure all those discarded empty boxes and wrapping paper! Confidence: Medium-High

Tomorrow night: It’s a chilly ride home from Grandma’s house!… even as winds begin to ease late evening and overnight. With mostly clear skies, temperatures have no problem falling into the 20s. Even with the lighter winds, wind chill values dipping to the lower teens add quite a bite. Confidence: Medium-High

A LOOK AHEAD

Winds on Tuesday aren’t nearly as gusty, but they’re still breezy enough for another wintry feeling day. Partly sunny skies have trouble moving the mercury, and after a chilly start, highs only max out in the mid-30s to around 40. A weak pulse of energy overhead could bring a flurry or two during the afternoon into evening. Otherwise we’re looking at Tuesday night lows in the low-to-mid 20s. Confidence: Medium

Even colder air settles in Wednesday, with a decent chance many folks don’t break the freezing mark. Partly-to-mostly cloudy skies early gradually clear out, but the loss of sunshine early does its damage. Winds aren’t a huge factor, but may be just breezy enough to add an extra chill to highs only in the low-to-mid 30s. Confidence: Medium
