Forecast: Four days of sunshine

By Jason Samenow

Late week looks troublesome again

* Outside Now? Temps, Clouds, Webcam & More: Weather Wall *


Today: Mostly sunny. 55-60. | Tonight: Clear and cold. 33-39. | Tomorrow: Mostly sunny. 65-70. | A Look Ahead


Having adapted to the dark overcast of the past 5 days, many of us will gleefully squint today as sunshine makes a glorious and overdue return. A warming trend will accompany the emerging sunshine, with temperatures tomorrow through Thursday nearly 25 degrees higher than they were over the weekend. The return of rain Friday into Saturday will once again be ill-timed, but this week's rainmaker will not be as cold or long-lasting.

Today (Monday): The day gets off to a frosty start north and west of the beltway, but the sun's long-awaited return will steadily warm the air all morning long. By afternoon, most places will reach well into the 50s, with a few 60 degree readings around. Winds will generally be light, from the north at 5-10 mph. Confidence: High

Tonight: It will be another frosty one for the normally colder suburbs, with lows falling to the low-to-mid 30s under clear skies. Elsewhere, it will still be on the chilly side, with lows 35-40. Confidence: High

Keep reading for the forecast through the work week

Tomorrow (Tuesday): After a crisp start, we'll have sunshine with the mercury headed up towards 70. This is the fine weather October is known for, and after the recent foulness, much-deserved. Confidence: High

Tomorrow Night: Clear and cool, with lows ranging from 35-40 in the cool spots, to the mid-40s downtown. Confidence: High


Absolutely beautiful weather sticks around Wednesday and Thursday. Both days begin in the upper 30s to upper 40s (colder suburbs to downtown) with afternoon highs around 70. Confidence: Medium-High

Clouds increase Friday ahead of a strong cold front, which will bring the slight threat of rain late in the day. But a good part of the day will be dry and mild, with highs again around 70. Rain chances increase as Friday night wears on, with lows in the 50s. Confidence: Medium

Showers (possibly heavy) and even thunderstorms are likely Saturday as the cold front barrels through the region. It will remain mild for one more day, with highs in the 60s. Clearing will probably occur between some time Saturday afternoon and early Sunday morning. The exact timing is uncertain at the moment. It should become breezy and cooler Saturday night, with lows in the 40s. Confidence: Low-Medium

Chances are good that sunshine will return Sunday, but it won't be as mild as the prior five days. Highs will probably only be around 60 (though that's much better than last weekend's mid-40s to low 50s). Confidence: Medium

Saturday is the unveiling of the new Heritage Trail in Columbia Heights. Should be an excellent event. Fingers crossed...

Looks like IAD dropped to 33 this morning, and BWI 35. (DCA just to 40). Anyone have frost where they live?

Rain totals anyone? In s. Arlington, my backyard rain gauge gave me 3.90 inches for this past multiday event.

Light frost in Columbia on the car around 7am, nothing on the grass.

Also had some light frost on the car this morning. No match for the wipers though...

JoJo, I forgot to get a rain total but we got 2" snow accumulation at 1900 ft in the mountains east of Front Royal Sat night/Sun morning. Pics here.

No frost in my part of Arlington. We could get more thirties tonight.

It has almost never stayed in the forties in October in previous years, not even when we got the snow in 1979. The rare times it has happened in the past were very late in the month, near Halloween.

anyone have any idea about the mold spore levels today and for the rest of this week? a link was posted a while back, can't find it.

Absolutely wonderful rain!

3.25 inches in our rain gauge. Closest official Weatherbug reporting station, Children's Hospital (about 1.5 miles west): 3.85 inches.

Bring on lots more at the end of the week!

I just checked and there is 2 1/8" in my bucket (total not adjusted for evaporation). It sounds like some areas to the south really missed out on the rain. I was watching one of the tv channels and I think they said Culpeper only got something like 0.18" of rain.

I wouldn't mind a bit more, but I'm rooting for the front to pass through early on Saturday.

Tom, it looks like NBC4 has pollen and mold spore counts.
