The traditional etymology of the word April is from the verb aperire, which means "to open". (Wiki) This definition is precise, and correlates well with the month that signifies the beginning of the growing season here in Wisconsin. Average temperatures increase ~15 degrees and daylight hours extend over one hour. These two ingredients, warmth and longer days, encourage the spring growth that shapes our lifestyle.
Utilizing intraseasonal oscillations (ISO) and applying a cycling weather pattern called Lezak's Recurring Cycle (LRC), we attempt to project weather conditions weeks and months into the future. The outlook for April, based on our current interpretation of both, is listed below. (http://tiny.cc/isowiwx)
•Below average precipitation.
•Below average temperatures first half of month.
•Above average temperatures second half of month.
•Two notable storms will take place within the region;
Around the 3rd. (Draco, Orko)*
Around the 10th. (Brutus, Fryer, Plato)*
•The final week should include a steady warm-up followed by a frontal passage providing a sharp cool down to end the month.
The time frame of the second and final week of the month could include severe weather chances just outside the state border. Stick with Wisconsin Weather forecasters Justin Poublon and Hunter Anderson for daily forecasts.
