FORECAST IN DETAIL


Our warm-dominated December continues through Thursday with temperatures managing to reach the 50s when we should be seeing only 40s. Low temperatures are also running to the warm side, but all of this is forecast to change by Friday as a more vigorous cold front returns area conditions back to seasonally cold levels. There is even a chance to be slightly colder than normal this weekend into next week.

After some slight shower threats today, our next rain maker arrives later on Thursday into Thursday night. Far western sections may eke out a flurry or two by Friday morning.

Today (Tuesday): A very weak cold front is slow to clear out the clouds today. Expect a mostly cloudy start with a slight chance of a shower (20%) during the day too. Winds pick up out of the west and northwest to reach about 10-15 mph with sometimes higher gusts. By the mid-to-late afternoon, we should see efforts at partial sunshine. Temperatures range through the mid-to-upper 50s, but higher winds at times offer a bit of a wind chill today. Confidence: Medium-High

Tonight: Some scattered clouds and turning colder with lows ranging from the freezing mark in the outer suburbs to the upper 30s in the city. Winds settle down to light levels. Confidence: Medium-High

Tomorrow (Wednesday): Mostly sunny skies greet the middle of the week with temperatures still running warmer-than-normal in the mid-to-upper 50s (as Jason noted yesterday, we can’t rule out a 60-degree high or two in southern areas). Light breezes make this a decent day. Confidence: High

Tomorrow night: Partly cloudy with lows dropping through the 30s again. Outlying areas could reach the freezing mark or slightly colder. Confidence: Medium-High

A LOOK AHEAD

Thursday brings another weather system toward our area. This particular low pressure is carting along a much more effective cold front. But for Thursday at least, we should still see warm temperatures with highs in the 50s, increasing cloud cover throughout the day, and a risk of afternoon into evening showers (20% eastern half to 40% risk west of the city). Thursday night sees rain likely all-around with temperatures staying warm initially and only falling more significantly toward dawn back through the 40s (30s in the far western suburbs where a few flurries are also possible). Confidence: Medium

Friday returns us to what December is supposed to feel like with daytime temperatures only in the 40s and variable sky conditions. Probably the worst aspect of the day is windy weather that sometimes make the 40s feel like 30s instead. Partly cloudy and still a bit blustery Friday night as temperatures dip into the upper 20s to middle 30s. Confidence: Medium

The weekend continues the theme of climatologically appropriate weather with partly to mostly sunny skies and highs in the 40s. Lows range from the mid-to-upper 20s in the outer suburbs to the low 30s in the city. With no inclement conditions expected, you can’t blame the weather for slowing down any last minute holiday preparations. Confidence: Medium
