Oshkosh Half Marathon - April 21st - Wx Forecast
Utilizing Intraseasonal Oscillations (ISO) and applying a cycling weather pattern, Lezak's Recurring Cycle (LRC), I attempt to accurately project weather conditions weeks and months into the future.
The output of the forecast model for April 20-22 in Oshkosh is above. Interpreting the numbers, odds are, temperatures will be around 60 degrees for the daytime high. The 25% chance of precipitation means it has precipitated in 1 of 4 cycles thus far. A zero in the Pcpn column suggests that measured precipitation has been very light. Wind may be more of a factor than precipitation. There is a 50% chance of winds blowing over 10 mph for the entire day. This means in 2 of 4 cycles the average wind speed for the entire day at KOSH was over 10 mph.
A graphical forecast based on the same principles as above, is below.
