Today: Becoming partly cloudy, warm. 84-87. | Tonight: Cloudy, late showers possible. 65-69. | Tomorrow: Cloudy, showers likely. 74-77. | A Look Ahead


We'll have another pleasant day to enjoy before our next weather system makes a mess of things the rest of this week. Clouds move in later today foreshadowing our weather to come. From Wednesday onward, a low in the southeast will feed moisture over the mid-Atlantic teaming up with a slow-moving cold front to provide rain chances into the weekend.

Today (Tuesday): Picture what you experienced yesterday and add a few more afternoon clouds and you're good to go. Another warm and pleasant day is in store for the area as the last threads of high pressure hold sway overhead. Morning sunshine will give way to increasing high clouds in the afternoon and temperatures will climb to the mid-80s. Skies will likely become cloudy enough not to warrant the Nice Day sun, but for my money, it will be just fine. Winds will veer from westerly to out of the south at 5-10 mph. Confidence: High

Tonight: By nightfall we'll see clouds masking the skies overhead. By the early morning, there's a slight chance (<30%) of a shower by the time you awake. Overnight lows will be mild, in the mid-to-upper 60s. Winds will continue to veer overnight, blowing easterly at 5-10 mph.Confidence: Medium-High

Keep reading to find out if and when fair weather might return...

Tomorrow (Wednesday): Our quick shot of late-summer warmth will be over tomorrow. Continued easterly flow will keep the clouds overhead and the temperatures down. Chances for rain will also steadily increase throughout the day with the steadiest showers arriving by the evening, hopefully post-commute. Daytime highs will be in the mid-to-upper 70s, and winds will blow from the east/northeast at 7-15 mph. Confidence: Medium-High

Tomorrow Night: Once these showers move in, they won't be moving out any time soon. I'm not calling for a non-stop deluge or anything, but light to moderate showers with intermittent drizzle should be the norm into the morning hours. By Thursday morning we may pick up a quarter of an inch of rain. Overnight lows will dip to the lower 60s, and east winds will continue near 10 mph. Confidence: Medium-High


Thursday, the Appalachians may catch enough moisture to give us a brief lull in intensity, but I expect showers to continue off and on through most of the day, with moderate showers arriving by late morning/noonish. These showers could drop another quarter inch or so of rain. Cloudy skies and rain will again limit our highs to the lower 70s. The chance for showers continues overnight, and lows will reach the mid-60s. Confidence: Medium-High

Friday sees no respite from our rain chances. Though coverage and intensity begin to dwindle, most of the area will still see at least a passing shower or two. Clouds will continue to sock us in though, and highs will struggle to warm to the mid-70s. Mostly cloudy with continued chances for showers overnight, with lows in the low-to-mid 60s. Confidence: Medium

Saturday we may begin to slowly break out again. Showers may taper off in the morning with the possibility of some slow clearing by evening. The considerable cloud cover and post-cold front air mean highs will probably peak near 70 degrees. High pressure begins to work in overnight continuing to slowly clear our skies, leading to comfortable overnight lows in the upper 50s. Confidence: Low-Medium

Sunday we may see a return to pleasant weather. High pressure over Pa. may bring partly-to-mostly sunny conditions to the metro region with daytime highs in the mid-70s. Confidence: Low-Medium

So, I probably need to pull the cord and get a tent for my late afternoon outdoor wedding on Saturday?

Saturday could turn out ok with the possibility of diminishing chances of rain and maybe some clearing skies, especially by evening (as the forecast above indicates). But forecast confidence is not very high b/c it all depends on how much high pressure (that will be centered to our north) is able to influence our weather, which is uncertain at this point.

Today's weather is absolutely fantastic!

Not so the cool, damp spell expected from tomorrow through Saturday. I wish there were a way to keep that extended cruddy spell OUTTA HERE!!!---El Bombo.

Hey, AmberGale, my wedding's on Saturday, too! I'll cross my fingers for both of us.

And thanks for the reassurance, uncertain though it may be, Dan. We've been checking obsessively for your "look ahead" for a week now -- the CWG forecasts are my favorite!
