Today’s Daily Digit
A somewhat subjective rating of the
day’s weather, on a scale of 0 to 10.

Near or below 40 for many, but to be expected in winter. I want more sunshine, less breeze though.

After today’s increasing clouds and light breeze, the forecast quickly gets trickier for late tonight through tomorrow. We encourage you to play it safe and watch for iciness around and after midnight until at least the morning tomorrow, and maybe into the midday. We hope not too many of your plans will be disrupted but at least we have the prospect for thawing by late tomorrow for places that turn icy. As we go toward next week, mild weather lovers can look forward to 50 degrees again! But let’s all get through our weather challenge tonight and tomorrow, first!

””Snow Potential Index: 4 (↑) - Ice more of a worry, particularly N&W of DC, but a burst of snow is possible overnight Fri into early Sat a.m.

Today (Friday): With just a bit of sun in the morning before clouds move in, we will need to perhaps stay bundled-up a bit. High temperatures in the upper 30s to near 40 are just a touch below average, but may feel cold at times without and north breezes from 5 to 10 mph. Confidence: Medium-High

Tonight: Be sure to see our Zone Forecast thoughts, they’re still relatively on track. Precipitation moving in may arrive by 10 p.m. to midnight, though the air is rather dry to start so it may evaporate a bit early. We think there’s a decent shot, particularly D.C. and north or west, of seeing some snow to start. Where it’s frozen, precipitation should change to sleet and quickly to freezing rain after maybe a ground coating of snow or a bit more. Some ice accumulation is possible, at least for a few hours all the way into the inner suburbs and the city, but the worst (including potentially more significant road impacts) should be north and west. As you get further south and east you might wonder what the big deal is as more and more falls as plain rain. Low temperatures dip to mainly the upper 20s and lower 30s. Confidence: Low-Medium

Tomorrow (Saturday): The sun rises and freezing rain may still be sticking around in the northern and western DC suburbs but the freezing line should continue edging north and northwest. By midday most or all locales should change over to rain. Some spots could end up fairly icy by that time though, particularly on elevated surfaces. Remember to still drive carefully, even as temperatures rise past freezing and toward highs in the upper 30s to low 40s. Light showers could linger through much the day but amounts are unlikely to be much and they should end during the afternoon. Confidence: Low-Medium

Tomorrow night: It’ll clear out and we should slowly dry the surface where it’s just liquid, with the help of a light northeast breeze. Low temperatures downtown may stay near 30 with suburbs potentially hitting the mid-20s, west and north of town. Confidence: Medium

Sunday: It’s pretty cloudy and there’s even a 20% chance of showers (light ones) by the afternoon. It may feel a bit nippy as well, with little sunshine as high temperatures only rising to near 40. Confidence: Low-Medium


Sunday night: Showers and sprinkles could continue overnight (30-40% chance) so you may want to take that umbrella if going out. Overnight low temperatures are kept up by the clouds overhead, prohibiting the atmosphere from cooling lower than the mid-to-upper 30s. Confidence: Low-Medium

Monday may be yet another day where we don’t see much sunshine, unfortunately. Are there sun-haters out there this time of year? I know there are snow lovers, but a cloudy January day isn’t that enjoyable, right? We have a good (roughly 50%) chance of showers in the morning and then, hopefully, some slow clearing before sunset. Luckily, we see temperatures hit and pass the 50 degree mark, perhaps even well into the 50s. Confidence: Medium

Come Tuesday, we may be hoping for some time to dry out a bit, and the good news there is that skies like they could clear out by lunchtime, with decently enjoyable temperatures to be had by afternoon -- I’m talking near 50 to the mid-50s. Confidence: Low
