FORECAST IN DETAIL


Our chillier than average pattern, which essentially started with Superstorm Sandy at the end of October, will also close out November. Today’s not bad at all though, with partial sunshine and some of us near 50. Tuesday’s the most miserable day of the week with a cold rain, which may mix with snow west and northwest of the beltway. Then we have a slow warming trend into the weekend.

Today (Monday): Temps are a few degrees below average, but it’s improvement from the weekend. Under partly sunny skies, highs range from the mid-40s in our normally cooler spots to near 50 from the District south. Winds are from the west at 5-10 mph. Confidence: Medium-High

Tonight: This is where things start to get interesting. Clouds increase as a fast moving disturbance approaches from the southwest. After 1 a.m. there’s a 60 percent chance (highest odds west) of rain, sleet and/or snow. West and northwest of the beltway (especially as you move up in elevation), snow or a wintry mix is more likely, whereas everywhere else rain or a rain/sleet mix is more likely. Except above 1,000 feet in elevation (where temperatures will be close to freezing), no issues with slick roads are particularly likely, with lows 34-39 (northwest to southeast). Confidence: Medium

Tomorrow (Tuesday): For most of us, expect just a cold rain that may mix with sleet or a few wet snow flakes at times. West and northwest of the beltway, a wintry mix of rain, sleet and/or snow is likely with snow and sleet most likely when precipitation falls steadily. In the colder spots with some elevation to the north and west, maybe there’s enough snow to whiten grassy areas. Precipitation may start to taper off by mid-to-late afternon. Highs range from the upper 30s to low 40s (northwest to southeast). Confidence: Medium

Tomorrow night: Precipitation is most likely out of here, with gradual clearing.and cold temperatures. Lows range from the mid-to-upper 20s in the colder suburbs to the low 30s downtown. Confidence: Medium-High

A LOOK AHEAD

Wednesday through Saturday appears to be yet another quiet, albeit chilly stretch of weather. Wednesday and Thursday are both partly to mostly sunny, with highs in the mid-to-upper 40s. By Friday, we may close in on 50 under partly sunny skies, but I wonder (lower confidence) if we step back down into the 40s Saturday with the possibility of a cool wind from the northeast. Overnight lows generally range from mid-to-upper 20s in the colder suburbs to the low-to-mid 30s downtown. Confidence: Medium

Sunday has the potential to be the mildest day of the week as winds may come in out of the south. However, clouds should increase ahead of a cold front approaching. Highs probably make the 50s with a 30 percent chance of showers by late in the day. Confidence: Low-Medium
