8/10: Well into the 50s for the last day prior to meteorological winter? I’ll take it!

EXPRESS FORECAST

Today: Partly to mostly sunny. Highs: 53-58. | Tonight: Variable clouds. Lows: 42-48. | Monday: Partly sunny. Highs: Near 60.

FORECAST IN DETAIL

How about some above normal temperatures for a change? Despite a lack of significant sun, temperatures rise to end the weekend and begin the week anew. Then, seemingly starting a pattern, the warmth is quickly followed by a chance for some snow after a cold front sags through late Monday to usher in the beginning of meteorological winter.  The cooldown is short-lived though as milder temperatures quickly return for the midweek.

Today (Sunday): If you’re looking for a decent day to get those outdoor Christmas lights up, take advantage of today. With clouds and sun fighting for control of the skies (clouds may win in overtime), a steady southerly wind helps push our temperatures higher, with max’s reaching the mid-to-upper 50s. Certainly an improvement over the recent chill, and an awfully nice way to close out a long weekend. Confidence: Medium-High

SNOW POTENTIAL INDEX
A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

1/10 (): An inch of snow tricky to attain Mon night into Tues, but definitely a chance for wintry precip in the area.

Tonight: Showers are still held at bay but as the cold front inches closer, clouds may start to increase overnight. Southwesterly winds continue to pump in the mild air and that keeps overnight temperatures rather mild for it being the early hours of December. Overnight lows drop only into the 40s across the region. Confidence:Medium-High

Tomorrow (Monday): The first day of meteorological winter certainly doesn’t feel like it as we remain on the warm side of the cold front for much of the day. What little moisture comes with it is likely squeezed out in the mountains, and we’re looking at only a 15% chance for showers later in the afternoon as the front approaches. Temperatures top out in the upper 50s to lower 60s. Confidence: Medium

Tomorrow night: Our warm spell comes to a close and we turn the clocks back to winter as the cold front sags through and high pressure over southern Canada ushers in a colder regime. A weak wave developing along the front could be enough to squeeze out some showers, possibly of the snow or mixed precipitation variety before dawn, as overnight temperatures drop into the upper 20s and lower 30s. Confidence: Medium

A LOOK AHEAD

Surface cold temperatures hold fast into Tuesday and we get our first “Decembery” day of the month. “30s and rain” is a phrase no one likes, but it looks to be possible as scattered showers are likely with temperatures just a bit too marginal for it to stay frozen past mid-morning or so. Still, there’s a chance that snowflakes or sleet pellets will fly for the commute. As of now, accumulations should be sparse and relegated to the north and west, if any at all. We’ll need to watch though. Daytime highs are stuck in the mid-to-upper 30s under mostly cloudy skies. The cold doesn’t last long and warmer air begins to move in overnight. There’s still a slight chance of a shower/flurry early, before settling to a mostly cloudy overnight, with temperatures in the mid 30s, slowly rising toward morning. Confidence: Medium

Weak high pressure over the southeast on Wednesday is enough to warm us back up, but it’s not enough to clear out our skies. Mostly cloudy conditions prevail for most of the day but temperatures rise back into the low-to-mid 50s. A sprinkle or two is not out of the question, but once again they’re likely contained back to the west in the highlands. Confidence: Medium
