10:05 a.m. — Winter weather advisory discontinued for immediate area but extended to noon north and northwest
Just plain rain continues to fall in the immediate metro area, where the winter weather advisory was canceled. But, in upper Montgomery, Howard, Anne Arundel (mainly the north part) and western Loudoun counties, and locations to the north and west, temperatures are hovering near 32 degrees and so the winter weather advisory has been extended until noon. In this zone, continue to watch out for slick spots on untreated surfaces
Scroll down for the detailed forecast for the rest of today through the weekend. Some iciness could redevelop tonight!
8:05 a.m. — Mostly plain rain falling with temperatures at or just above freezing
At 8 a.m., Dulles Airport, normally one of the colder spots in the area, has risen to 33 degrees with plain rain falling. Reagan National, normally one of the milder spots, is up to 35.
While we do still some temperatures hovering around 32 degrees north and west of Washington on local temperature networks, all indications are that roads and other surfaces are mostly just wet rather than icy. That said, we still advise caution as you head out as a few slick spots on sidewalks, driveways, parking lots and some neighborhood roads could linger through midmorning or so.
The highest chance of any lingering slick spots through midmorning will be above (to the north) and to the left (to the west) of the yellow line on this map:
6:25 a.m. — Wintry mix falling with temperatures near freezing, some slick spots
In the immediate area and to the south and east, a mix of plain rain and freezing rain is falling with temperatures between 31 and 34 degrees. In our far northern areas, some sleet mixes in and, north of Interstate 70, the precipitation changes to snow.
Based on the reports we’ve seen so far, main roads and treated surfaces are fine in the immediate area, but we would use caution walking and driving on untreated surfaces, including sidewalks, driveways and neighborhood roads. Some surfaces are just wet but others are icy.
Because temperatures are within a degree of freezing or so, conditions can vary quite a bit from area to area — there is a big difference between how surfaces will be in areas that are 31 versus 33. Generally, the chances of encountering slick surfaces will increase as you head north and west from downtown.
That said, some spots east of town are also near freezing, so everyone should use caution taking those first steps outside.

Today (Monday): Watch out for slick spots early this morning, especially in our colder areas north and west of downtown. Temperatures should gradually rise above freezing from southeast to northwest this morning, allowing any lingering mixed precipitation to change to plain rain. This afternoon, we may see the rain ease or stop for a time, but it remains overcast and bleak with highs only in the mid-to-upper 30s. Confidence: Medium
Tonight: Rain, possibly mixed with sleet, is likely overnight. Temperatures may cool enough in some of our colder areas north and west of the Beltway for some pockets of freezing rain and slick spots could redevelop. Lows range from 30 to 35 Confidence: Medium
Tomorrow (Tuesday): Cold air is wedged into the region and rain is likely, except freezing rain in our colder areas, mainly in the morning. By afternoon, most of the region should be above freezing with just plain rain. Highs range from the mid-30s in our colder spots to 40 or so downtown and to the south and east. Confidence: Medium
Tomorrow night: Rain should finally end by around midnight, with slow clearing toward morning. Temperatures hold steady in the 30s to near 40. No hard refreeze is expected. Confidence: Medium
A LOOK AHEAD
We get a chance to dry out Wednesday and Thursday — with seasonably chilly highs in the mid-40s or so and a dose of sunshine. Cold at night, with lows ranging from the mid-20s to low 30s. Confidence: Medium-High
Our next chance of rain comes along Friday. It won’t rain the whole day and is likely the mildest day of the week as winds from the south boost highs well into the 50s. Showers may continue at times well into Friday night, when lows are near 40. Confidence: Medium
Skies become partly sunny over the weekend. Temperatures are back toward seasonal norms, with highs in the 40s and lows in the 20s to low 30s. Confidence: Medium
