EXPRESS FORECAST

Today: Partly to mostly sunny. 57-60. | Tonight: Cloudy, chance of light rain late. 40-44. | Tomorrow: Cloudy, chance of rain. 48-52. | A Look Ahead

FORECAST IN DETAIL

We may be able to salvage one more pleasant day before a combo of systems tries to put a damper on our shortened work week. Skies will be partly to mostly sunny and pleasant overall -- similar to yesterday. After another shot of rain on Monday, uncertainty builds in the forecast details through Thanksgiving. One thing is more certain though, and that's that the whole of it will incorporate the chance of light showers and a good amount of gray.

Today (Sunday): We'll be caught between retreating high pressure to our northeast and developing low pressure to our southwest. While it had looked like today might be quite cloudy with a late chance for the wet stuff, it turns out the high will be strengthening as it moves away. As a result, partly to mostly sunny skies should last into afternoon. Toward evening, more clouds may begin to filter in from the southwest. We'll continue to be mild, with highs in the upper 50s and winds from the north around 5 mph.Confidence: Medium-High

Tonight: Clouds continue to increase overnight, and some of us (especially south) may see some patchy late rain by daybreak. Temperatures will be a bit warmer with the clouds, with lows in the low-to-mid 40s. Winds will be from the northeast at 5-10 mph.Confidence: Medium

Tomorrow (Monday): Rain arrives, likely in the form of periods of light rain and drizzle. Not really a nice day at all, quite raw and damp. Highs will likely reach no higher than the low 50s, and some may not make it out of the 40s. Winds will be light but steady, out of the northeast near 10 mph. Confidence: Medium-High

Tomorrow Night: Rain should be dwindling to more isolated showers through the night. Skies will still be overcast and lows will just dip into the mid-40s. Winds will be out of the north-northeast at around 5-10 mph. Confidence: Medium

A LOOK AHEAD

Tuesday the low-pressure area moves up the coast and away, but with no high pressure to take over, our marine air mass stays around. For us that means mostly cloudy skies, with a slight chance (20%) of some light showers or mist. Highs will be held down in the mid-50s. Overnight, more of the same with perhaps a slight increase in shower chances. Expect lows in the mid-40s. Confidence: Medium

Wednesday doesn't look much better as another slow-moving system approaches. Skies will again be mostly gray and the chances for showers continue to increase, highest north of town. Highs will depend on the system's track, likely in the mid-50s. But if it tracks more to the north, we may stay drier with some sun possibly pushing us toward 60. Confidence: Low-Medium

Our preliminary Thanksgiving Day forecast call for mostly cloudy skies and another slight chance of rain showers, with highs in the mid-50s. Confidence: Low-Medium

Looks like we got less sun yesterday than forecasted, while today will be more than was predicted.

No complaints though.

When does the real cold weather and possible snow start to arrive? GFS, AccuWx, FootsForecast.org, etc. starting to get excited about early December. What does the gang think?

@DHinDC

Agree that early December looks prime for a pattern change to a cooler, more winter-like regime. Too soon to say if wintry precipitation potential is high.

Early impression is that we've got yet another boring raw coastal system & not enough cold air for snow.

Next week some time I'll grade both November and meteorological autumn...right now it's tending towards a C-minus on both counts, with too many wet "coastals". We could be trending towards a colder December...a caution in an El Nino year, which could lead to a mild Jan.-Feb.
