Forecast in detail
With a somewhat sunny sky, light breeze and normal temperatures today it all starts out very simple and straightforward. The dynamic storm system goes wild ride with heat, scattered light morning rain, steady and heavy afternoon rain, and heavy storms flooding and damaging winds tomorrow night. On Christmas Day, the wind blows in the teens and 20s.
Today (Wednesday): Let’s get out of the easy tomorrow first. With too much pressure on the control we are somewhat sunny and dry. Morning temperatures rise to 30s and under, reaching a high of 40s in the afternoon. A light breeze develops from the south into the afternoon. Confidence: Medium High
Tonight: The sky will become cloudy throughout the evening and night as the vast storm system begins to approach from the west. The blanket of clouds and a slight breeze from the south and southeast keeps the temperature from falling too far, from low to mid-40s. Confidence: High
Tomorrow (Christmas Eve): Scattered light rain is likely in the morning as temperatures rise in the 50s. In the afternoon, especially in the district and west of Interstate 95 the rain should become steady and heavy for some of us. Winds from the south and southeast, blowing at 30 mph in the afternoon, will be close to 60 or in the 60s. Confidence: Medium
Tomorrow night: The evening may begin with heavy rain centered east of DC and I-95. Most of us will then see heavy storms moving from west to east in the evening, especially from 10pm to 2am which have the potential to create some flooding and damaging winds. There is even a small chance of a hurricane. The rain should go east overnight, with a total of 0.75 to two inches of rain, and it will end in wet snow or sleet (no accumulation expected).
Overnight winds can come from behind a cold front to the west, blowing at speeds of 40 to 50 mph at a time, clearing the sky at dawn, with temperatures dropping from the upper 20s to the mid-30s until the morning. Confidence: Medium High
A look ahead
Get some sun and bone cooling ready Christmas Day. We have temperatures rising in the 30s, with winds blowing at 15 to 20 mph from the west and up to 30 mph. That means the air cools only in teens and 20s. I was able to see a few snowfalls as well. Friday night the wind is low, but the breeze stays on the sidelines as the Midsteins sink into the lower 20s. Confidence: Medium High
The Weekend It starts with a fairly sunny and cold Saturday, with a long morning breeze and a maximum of 30 to 30 in the afternoon, with a low of Saturday nights in the 20s. Sunday with slightly warmer and milder breezes in the 40s should see somewhat sunny skies again. Confidence: Medium High
Possible index of snow
A daily assessment of the possibility of at least 1 inch of snow next week at 0-10 levels.
1/10 (↓): Heavy rain on Thursday night will end in a little wet snow, but accumulation in the DC metro area is unlikely.
