Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

Despite a layer of milky cloud cover, temperatures reached 60 degrees for the second straight day.  By Sunday, they’ll make it four in a row at 60 or higher when they make a run at 70+.  Considerable cloud cover at times is the only factor that may prevent multiple records from being shattered.  The weekend closes with a chance of showers and even thunderstorms.

Through Tonight: Mostly cloudy and very mild. Lows range in mid-40s in the cooler suburbs to near 50 downtown.  These are near or above average highs.  Winds are from the southwest at around 10 mph.

Tomorrow (Saturday): The tropical flow from the southwest drives both warmth and cloud cover into the region.  High reach the low-to-mid 60s, with winds from the southwest at 10-15 mph.  A little more sun than expected could push temps into the upper 60s, especially south of the District.  The record highs of 61 and 62 at Dulles and BWI, from 2011, are certainly achievable.  Reagan National’s record of 68, from 1923 (set at 24th and M St., D.C.) is more of a stretch.

Saturday night: Mostly cloudy and unseasonably mild, with record warmth a virtual certainty.  Lows are around 58-60 downtown and in the mid-50s in the cooler suburbs.  If Reagan National remains at 59 or higher, it will match or break the warmest minimum temperature during the month of December on record.  The record high minimum for the date is 49 (from 1923), which will be shattered. There’s an outside chance of a shower.

Sunday: Mostly cloudy and warm! If cloud cover is stubborn, we only reach the mid-to-upper 60s, but if the sun comes out in earnest lookout – highs into the mid-70s are attainable.  A good ballpark estimate is for highs of 69-74.  There’s a 30 percent chance of showers starting after around 1 p.m. Sunday afternoon.  The better chance of showers, and perhaps a thunderstorm is after dark.  Winds are from the southwest at 10-15 mph, with higher gusts.

Here are the record highs, all of which are in play:

BWI 70 (1889)
Reagan National 72 (1889 from 24th and M St., D.C.)
Dulles 67 (1984)

60-degree streak: As noted above, today marked our 2nd straight day at or above 60. We should at least run the streak to 4 days by Sunday. If we manage a 60-degree reading on Monday (possible), the 5-day 60+ streak would be the longest on record in the 2nd half of December, notes CWG’s Ian Livingston.
