Precip Scale

We provide free long-range U.S. National, U.S. Local (searchable by zip code), North American, Canadian, and Australian weather forecasts for high temperatures, low temperatures, precipitation areas and range of amount to expect, daily snowfall totals and snow on ground as well. Currently posting maps out until the end of 2020, viewable as the server gets them processed, these maps are a product of an analog forecast method that looks at the composite average of the past four 6558 day long cycles of nearly the same lunar declinational tidal effects in the global circulation, for comparison to this current cycle to get a better idea of how the underlying patterns are repeating under current conditions.

These maps are expected to be used for looking ahead more than ten days into the future, for the long term forecast use of farmers, truckers, livestock breeders, farm and irrigation equipment purchase decisions. Scan out ahead for the outbreaks of severe weather or dry conditions you need to watch for, or next years weather trends for planing future crop maturity length, planting times, or pasture rotation insights to optimize your application to your needs. Then as the date in question approaches, watch the standard 3 to 5 day forecasts from your usual National Weather Service, BOM, or Environmental Canada outlet to watch how this cycle differs from the average of the past four. It is not unusual to see swings in storm track further North or South than the past patterns in general and the start of the precipitation trends further West or East then some other cycles.

In general the passage of the expected frontal systems should repeat with in +/- 18 hours of the past cycle patterns so it is advisable to look a couple of days either side of your main date in question to watch the flow of the frontal patterns expected. The data gathered from Coop Stations used for this forecast method was read around 7 to 9 am local time (officially 8am) and recorded as the totals for the previous 24 hours. So some times the precipitation comes overnight, or early in the am the following day as it did the last time.
