FORECAST IN DETAIL


Today (Saturday): There could be some fog and/or sprinkles in the morning, but much of the day ends up precipitation free. It’s still rather cloudy throughout — hopefully including some periods of midday or afternoon sun? Even with the clouds, temperatures should be a good deal warmer than yesterday, heading toward 60 and maybe as high as the mid-60s if enough sunshine helps us along. Winds are light from the south. Confidence: Medium

Tonight: Any potential daytime breaks in the clouds fill back in overnight, leaving us quite overcast. There’s a slight risk of a shower, particularly early in the night and then again toward morning. Temperatures slowly dip down into the the mid-40s for much of the area, and closer to 50 downtown. Confidence: Medium-High

Tomorrow (Sunday): A weak front dips back to our south, and with the change in wind direction temperatures don’t do much off morning lows. Add in a passing shower risk much of the day, and it might not be the most pleasant one outdoors. While showers are bordering on likely (50% chance), I don’t anticipate lots of rain and it may focus north and west. Maybe a tenth of an inch, or even two, will be possible in the jackpot areas. Afternoon maximums are muted, only in the upper 40s to low 50s. Confidence: Medium

Tomorrow night: We’re cloudy again. Surprised? The front in the area heads back north, which means as little as temperatures rose during the day, we see a similar deal with them falling at night. Look for a range in the mid-40s to near 50. Confidence: Medium

A LOOK AHEAD

Monday brings another surge of warm air. And even without full sun, highs should range from the low to upper 60s, depending on just how much cloud cover. A cold front is on the doorstep though, and it should arrive as soon as around sunset, but more likely later in the evening. A few showers may break out by late afternoon, and there may be some heavy rain squalls with the front. Maybe even a bit of somewhat unusual December thunder! Cooler air comes in late night. Confidence: Medium

Tuesday features that cooler air filtering back into the region behind the front, but it won’t be super cold — basically just back to normal. Highs should make the mid-40s to near 50. The front doesn’t take a speedy run out to our east and south, so we should still see a good deal of cloudiness, and maybe a sprinkle or shower along with breezy conditions. Confidence: Medium
