Tomorrow, June 13, it will be hot, with temperatures exceeding 30°C (86°F) in inland regions.

As hot and humid southwesterly winds flow in, the daytime high in Seoul is expected to reach 31°C (88°F), about 3 degrees higher than today.

You should also keep in mind that there are forecasts for showers over the weekend.

Showers are forecast for the inland areas of the Honam region tomorrow, and for western regions on Sunday.

Let's take a look at the expected precipitation.

First, for tomorrow, 5 to a maximum of 20mm of rain is expected in the inland areas of the Honam region.

The day after tomorrow, strong cold air in the upper atmosphere will move downward, increasing atmospheric instability. This is expected to bring up to 50mm of rain to South Chungcheong and North Jeolla provinces, and up to 30mm to other parts of the central region, the Honam region, and the western inland areas of the Yeongnam region.

Please be cautious of safety accidents on this day, as there is a possibility of hail.

Next, let's look at the satellite imagery.

Today, the entire country is generally clear due to the influence of high pressure. Tomorrow, the nation will remain under the edge of a high-pressure system located over the sea east of Japan, keeping skies mostly clear across the country.

UV radiation will also be very strong during the day.

Let's look at the morning temperatures.

Seoul will start at 17°C (63°F), similar to today. Daytime highs will reach 31°C (88°F) in Seoul and 32°C (90°F) in Daegu, but since humidity is not yet very high, the perceived temperature will be slightly lower.

Light rain is expected on Jeju Island on Sunday. Next week, the heat exceeding 30°C (86°F) will continue, and showers may occur in inland areas due to atmospheric instability.
