Workweek Weather: Some showers from Jose possible this week

Although the autumnal equinox is this week, it won’t feel like a change of seasons. (WTOP/Storm Team 4)

WASHINGTON — The autumnal equinox is Sept. 22 at 4:02 p.m. It won’t feel like a change of seasons, however. The other season that it is right now of course is hurricane season, and the tropics are still busy.

Jose is being watched closely and it will be close enough to potentially bring some of us some showers.

Other than that threat, there will not be a lot happening this week while we are trapped in a strong ridge of high pressure in the eastern United States, while a deep trough of low pressure and cool weather sets up shop in the West.

Temperatures will be above average every day this week, but it will also be uncomfortably humid. Dewpoints will be in the low to mid 60s all week, which would make it feel as sticky as the mid-summer. Considering it’s mid-September, it might feel downright muggy to a lot of people.

With longer nights, temperatures have more time to cool to the dewpoints, and patchy fog may be a daily occurrence in the mornings.

Onshore flow between high pressure and the approach of Hurricane Jose will bring a chance for spotty showers on Monday at any time during the day, only isolated at most.

But Tuesday, even though landfall is not anticipated near the mid-Atlantic, the storm will be large enough for some of the outer bands to bring some showers to eastern parts of our area, mostly east of Interstate 95, in terms of highest likelihood.

The heavier rains would be along the beaches, and winds here would only be breezy at worst. As the center of Jose heads for New England, it will weaken, and the actual center of the storm may not make landfall at all.

This series of images is output from the RPM computer model, simulating the future satellite and radar/precipitation intensity. It shows the low level clouds, fog, and spotty showers on Monday as the strong easterly fetch is set up coming off the ocean. The hurricane can be then seen coming up from the south, parallel to the coast. Tuesday it shows some showers from the outer spiral bands affecting some of us. But the heaviest rainfall is along the immediate coast (and so are the windiest conditions, not shown). It should be noted that this model is much more west compared to the official hurricane forecast, especially when it’s close to New England. Many other weather models are farther east, bringing us even less of a chance for showers. So Tuesday’s weather here will be determined by last minute, mile-by-mile movements of Jose.

The model only produces a few tenths of an inch of rainfall at most for us. So if the model ends up being indeed too far west with Jose, we would be looking at even less rainfall on Tuesday. (Data: The Weather Company. Graphics: Storm Team 4)
The other story of this week’s weather will be above average daily high temperatures (normal high is around 80 this week for Reagan National). The GFS computer model shows a warm week ahead, especially the second half of the week. Notice the cooler temperatures for the beaches, though, because of the influence of Jose.
