Temperatures are still expected to be comfortable tomorrow night but shower chances remain even as early as trick-or-treating hours. The highest threat for rain will hold off until the overnight hours, but a few showers may slide in as early as the late afternoon and early evening. Even if these showers to come to fruition, they should be isolated and light in nature. Below is a look at the latest 4km NAM Model forecast for tomorrow afternoon at 5pm. A few showers may be dotting the radar around D.C. at that time but they should be rather light.4km NAM Model Composite Reflectivity forecast for tomorrow at 5pm
Winds look like they will be out of the south around 10 to 15 mph, so it will be a little breezy at times. Temperatures should be very comfortable through the day and evening, as high temperatures will approach the lower 70s and fall into the 60s by the evening. At this point, we think temperatures will stay in the 60s through the evening, so you won't even have to worry about wearing a warm costume out this year!
Showers and the potential for a few thunderstorms will be possible overnight into Friday morning. Winds only a couple thousand feet above the ground will be screaming at 60 mph or greater so a few high wind gusts may be possible early Friday with the rain.QPF Forecast through Sunday morning from the WPC
This system is expecting to bring more rain to the area, but not nearly as much as other locations in the U.S. Everywhere from Texas through the upper Mississippi Valley is expected to have multiple inches of rain from this system over the next few days. As the frontal boundary moves east, it will become more progressive and should exit the D.C. area by Friday afternoon. At this point, Friday is still expected to be warm with highs in the low 70s, but changes may be necessary if the frontal boundary decides to slow down and hang around.
