A daily assessment of the potential for *accumulating* snow for the next week on a 0-10 scale. More info


Today (Thursday): The morning commute should be safe with no more than a sprinkle or a little patchy light rain. While the main area of snow is likely to remain well to the south of the city (developing mid-to-late morning, starting as rain perhaps), a few bands of snow could work inside the beltway in the afternoon - though it may mix with rain - at least initially. If this storm suddenly surges north and we do get smacked, it would most likely come just in time for the afternoon/evening commute, so a check on the midday updates is a must.

Highs should be lower 40s to start the day and then slip into the mid-upper 30s in the afternoon as northwest winds pick up to 10-15 mph and (any) precipitation commences. Confidence: Low-Medium

Tonight: Snow remains possible into the evening (same chances as above) before tapering off. Skies do clear after midnight and temperatures drop notably with mid-20s northwest of town to near 30 downtown. Any snow (and/or rain) that falls will freeze overnight, so some slick roads can’t be ruled out. Confidence: Low-Medium

Snow accumulations: The map to the right tells the tale. If some moderate snow bands work far enough north, we might manage an inch or so (in the immediate metro region; otherwise, we may end up with little or no accumulation. Head southwest for more substantial snowfall.

Tomorrow (Friday): Finally a forecast that is not rife with ifs. A welcome dose of sun for the light-deprived but a brisk wind out of the northwest delivers a shocking bit of cold to the area. Highs do no better than the mid-to-upper 30s. Confidence: Medium-High

Tomorrow night: The stars shine bright as high pressure is strong over the area. The coldest spots in the suburbs could dip as low as lower 20s but most of us should do no worse than mid-to-upper 20s, which believe it or not is normal for this time of year. Confidence: Medium-High


Saturday will be the highlight of the weekend with highs in the upper 40s to lower 50s as a wind from the west is always good for warming this time of year. The winds stay up overnight and help to keep lows from dropping as much. Most areas hold in the upper 20s and even lower 30s downtown. Confidence: Medium-High

Sunday ushers in the leading edge of an Arctic airmass that is invading the Midwest. Winds gust out of the west briskly much of the day, making highs in the low-to-mid 40s feel less comforting than they should. At least sunshine remains abundant. As strong high pressure settles in for the night temperatures plummet. Lows are likely to be low-to-mid 20s with a few upper teens possible in colder exurbs. Confidence: Medium

Monday/Inauguration Day/Martin Luther King Dayor whatever name you prefer is likely to be a partly to mostly sunny one. More clouds are likely in the afternoon than the morning and we can’t rule out a snow flurry. The main problem - though - is that Arctic air is in full control and highs are unlikely to be better than low-to-mid 30s. It is a double pair of socks kind of day if you are going to be out, for parades or otherwise. Confidence:Medium
