Weather near the Musudan-ri Taepodong-2 ICBM launch site as we speak (per Japanese forecasting). It is (at 1900 local), nearly 3 degrees C with rain, so means almost to a sleet. I think the weather is bad for tomorrow (1 April), but from the next day (2 April), weather is better, average wind speed about 14km/h at the site. Weather varies from bad to so-so into the weekened. Perhaps they have their best shot from 6 April onward. This is subject to change. They cannot afford to launch in snow, sleet, rain and with high winds:

If weather remains bad for the duration of announced launch window(Apr. 4~8,) they could just wait for another few days and launch later. Even without official notification to the international body.
It is N. Korea after all.
