Forecast in detail It's a bit soupy today (for October) with slight chances for fog and rain chances, but still it's not a bad day overall. A low-pressure system — perhaps our incipient season's first nor'easter — may move up the coast this weekend. Moderate to heavy rain and gustier winds are all possible by Saturday night into Sunday, particularly east and southeast of the city but subject to shifts. Warmth and a few showers stick around into next week as well. Get our daily forecasts on your Amazon Alexa device.

A stray afternoon shower can't be ruled out. South-southeast breezes should stay under 10 mph. It's also a bit sticky at times with dew points eying the mid-60s. Confidence: High Tonight: Skies are mostly cloudy with a few showers possible, especially after midnight and toward dawn. Nothing heavy or long-lasting is currently expected.

Keep reading for the forecast into next week… Tomorrow (Saturday): Shower chances grow with time but mostly cloudy conditions may allow us to see some periodic sunshine. Shower chances are highest south of town — from where a non-tropical low-pressure system is expected to develop and move northward along the coast. Moderately muggy high temperatures should still reach the 70s — the 72-to-78 range seems a likely target, as of now. Easterly breezes noticeably pick up, nearing 15 mph by day's end. Confidence: Medium Tomorrow night: Overcast skies may bring higher rain chances and perhaps some heavier activity. Low temperatures bottom out in the low to mid-60s. Northeast winds blow near 10 mph. Late-night pounding of water on roadways is possible, especially east and south, so please be careful. Confidence: Low-medium Sunday: It's looking damp and mostly cloudy. Showers and perhaps some downpours may move through during the main body of the day. High temperatures should still reach around 70 degrees to maybe the mid-70s. Patchy flooding remains possible, especially south and east, along with gusty breezes at times, perhaps near 25 mph. Stay tuned for forecast tweaks as we track the ultimate path of this storm system. Confidence: Low-medium A look ahead Sunday night: Showers should wane and clouds clear a bit. Low temperatures get to the upper 50s to mid-60s. Confidence: Low-medium Partly to mostly cloudy skies for Monday's holiday and Tuesday may bring a few showers but nothing too disruptive as it appears now. High temperatures should top out in the 70s both days — perhaps around 80 degrees with more sunshine on Tuesday — accompanied by our persistent mugginess. We'll keep an eye on whether showers finally move out of our region a bit more as we get closer. Confidence: Medium Read more about Capital Weather Gang's confidence rating. |
