With the advent of newer technologies comes the ability to make forecasts well into the future. As with the case in short range forecasting, the big caveat is that mother nature can change her mind when it comes to forecasting weeks in advanced. Still, fewer things present as much of a challenge in meteorology as long range forecasts.
In the menus above I have created several pages including weekly/monthly forecasts, climate monitoring, ENSO/MJO, GWO stratosphere, and more to come in the future. Each forecaster has their preference for how they achieve their forecasts. Even if you are not looking to make your own predictions, these are also great tools to use simply for keeping up with the state of the climate.
