Following a wet pattern across Japan, a drier pattern settles in for late-week and weekend.
In the transition to spring, Tokyo has certainly been getting April showers. So far in the month of April, Japan's capital has received 133 mm (5.24 inches), close to their average for the entire month. More than 88 mm (3.5 inches) of that has come recently, since April 13.
Seoul, South Korea, has had about 70 mm (2.75 inches) so far this month, already beating the average rainfall total for April.
For those looking to spend some time outside in the sun, they will get their wish across much of Japan and Korea late in the week and through the weekend.
High pressure emerging from central China will shift into the East China Sea late in the week, bringing with it sunshine and warmer air.
Temperatures in Seoul will push near 20 C (upper 60s F), which a few degrees above normal for this time of year. Highs will hold near normal or just above average around Tokyo and Osaka.
The exception to this is northern Japan, particularly the island of Hokkaido, where a few spotty showers are likely Friday into Saturday. Total rainfall amounts will most likely remain below 6 mm (0.25 of an inch), but locally heavier showers could bring up to 12 mm (0.5 of an inch) in a few places.
The city of Sapporo already had 143 percent of their rain for the month as of Tuesday, April 21, totaling 101 mm (4 inches). With sunshine not returning until Sunday, some more rain could be added to that total before the end of the month.
Temperatures will remain well above normal in northern Japan, despite the continued threat for showery weather.
