A daily assessment of the potential for *accumulating* snow for the next week on a 0-10 scale. More info
Today (Sunday): High pressure overhead means partly to mostly sunny skies for much of the day and no flurries around like yesterday. The sun doesn’t do much for temperatures, though, with afternoon highs only in the mid-30s with light winds. Increasing clouds work back in later in the afternoon as our next disturbance closes in from the west. Confidence: High
Tonight: Skies turn mostly cloudy as low pressure approaches, and light precipitation may move in from the west after 4 a.m. or so (50% chance). We’re plenty cold at ground level with overnight lows in the mid-20s to near 30, but higher-up layers are probably too warm for much in the way of snow. That means if we do see precipitation it would likely be mainly in the form of light freezing rain or sleet. Confidence: Medium

Tomorrow (Monday): Monday starts with a 60% chance of light freezing rain, maybe mixed with sleet early. If precipitation is steady enough some roads and sidewalks could become slick by or during the morning rush, especially but not necessarily limited to north and west of D.C. Temperatures should rise above freezing from south to north mid-to-late morning (approx. 9-11 a.m.). Rain chances decrease by mid-to-late afternoon, but a lingering shower or two remains possible especially north of the District. Skies stay mostly cloudy through the day as highs reach the upper 30s to low 40s. Confidence: Low-Medium
Tomorrow night: Can’t rule out a few showers through the night, though chances decrease to around 20-30%. With considerable cloudiness and a warmer air mass moving in, overnight lows should stay above freezing, only dropping to the mid-30s to near 40. Confidence: Medium
Our warming trend really gets cranking by Tuesday. Mild air surges in from the south as the jet stream bulges north over the East Coast. Partly sunny skies help boost highs all the way to the upper 50s to perhaps the low 60s. An isolated shower isn’t out of the question. Expect partly to mostly cloudy skies Tuesday night with mild lows in the mid-40s to near 50 (that’s about 20-25 degrees above normal!) Confidence: Medium
Warmth hits its peak on Wednesday with highs in the 60s, potentially even near 70 if a strong cold front holds off long enough. Rain seems likely with the front and could be moderate to heavy for a time. Right now timing for rain looks like the afternoon or evening, but that is subject to change. Confidence: Low
Behind the cold front, temperatures turn much colder late week into the weekend, but probably not as cold as our recent cold blast.
