FORECAST IN DETAIL
Lucky for those of you with today off (I know many of us have to work), the stretch of excellent autumn weather continues -- notwithstanding some increasing cloud cover. Enjoyable conditions persist into Wednesday, but then it's downhill in a big way starting late Wednesday through at least Friday. A raw, soaking rain looks like a strong possibility. Whether the rain moves out by the weekend is an open question. Sunday shows more promise for clearing than Saturday at this early juncture.
Today (Monday): No doubt, the day will begin on the chilly side and be more cloudy than sunny. There should be enough sun to get us to 60 or perhaps a little higher but it will be brisk. Winds will be light from the east, at 5-10 mph. Confidence: Medium-High
Tonight: A relatively weak weather front will skirt through the area, producing some clouds but probably little or nothing in the way of rain (80% chance of no rain). Lows will range from near 50 in the cooler suburbs to the mid-50s downtown. Confidence: Medium-High

Tomorrow (Tuesday): Sunshine will return in force Tuesday behind the so-called front (whose main effect will be to change the wind direction, rather than cool the air). Temperatures will rise back up well into the 60s to near 70. It will be a little breezy, with a wind from the northwest at 10-20 mph. Confidence: Medium-High
Tomorrow Night: Under mostly clear skies, we'll have another crisp fall night. Lows will drop to near 40 in the cooler suburbs with upper 40s downtown. Confidence: Medium-High
On Wednesday, sunshine in the morning will yield to increasing clouds during the afternoon, with a 40% chance of rain by the P.M. commute. High will be near 60. Confidence: Medium
Rain is likely periodically (i.e. with breaks in the action) late Wednesday through Saturday as several waves of low pressure develop to the south and head up the coast. The exact track and timing of the various lows will determine how much it rains, where, when and for how long. But - in all likelihood -- everyone will get some appreciable rain during this period, and it will be mainly cloudy and raw. I'm thinking highs will be 50-55 during this stretch with lows in the 40s. It will probably also be breezy, with a wind from the east and northeast at 10-20 mph. Confidence: Medium
A few showers could (25% chance) linger into Sunday morning, but my best guess at this point is that we'll have slow clearing by afternoon. A very chilly air mass is likely to follow the departing storm, with temperatures not making much headway through the 50s. Confidence: Low-Medium

Decidedly overcast this morning, and the temp actually dropped a degree in the past hour. Hoping to see more sun soon!

Doesn't seem like we're going to get many breaks in the clouds today. Forecast updated, and nice day sun removed :(

When will the forecast for Saturday clear up (no pun intended)? I am planning my child's birthday party and would like an idea of what might happen hopefully a few days out. Thanks.

It looks mighty nasty later this week--but my main dance nights are tonight & tomorrow--Friday looks like the only dance night affected though I may have to visit Ballston most afternoons from tomorrow on this week.
IT IS DRY--BUT WE SURE DON'T NEED THE RAW WEATHER!!!
My mother reports it is snowing hard up in Eau Claire, WI--they expect about two inches!!!

Here's a link to an earlier post: Snow in October?
@ArlingtonWeather
We should have a better idea about rain prospects for Saturday by Wednesday.

What's the departure from normal temp wise for Sept/Oct?
It sure feels like we've been way below normal for some time now.
I know normal highs are still in the upper 60's but if the forecast holds for later this week, we'll be 15-20 degrees below that for several days.
Not good. Fall is supposed to be the nice time of year.

It was 80 degrees last Friday. Short memory, eh?

@Axel2
Re: the 80 degrees on Friday. Yes, we've had what seems like 1-2 days per week above normal recently, but the rest of the week has been well below normal. My question meant the average temp over the last 6 weeks or so.

Even if we get some decent rain this week it will be 3 weeks since we last had anything appreciable (9/26). It's just pathetic. Now if we miss it, we may go rainless the whole month of October.
