It's Official: TMD declares May 15 is the start of the rainy season

Unfortunately the heat index remains high (40-41C). Once the rain stops and the sun comes out, it's steambath time. 

Rain is in the forecast today,

Forecasters seem to be guessing, some say scattered rain before noon, others indicate the heavy stuff will be at mid afternoon. 

When they are not sure they simply say "scattered." You may get rain, or you may not.สกลนคร Sakon Nakhon
