When ever the weather patterns seem odd I always remember john saying this...
"If you look at one day, the temps might be 10-20 degrees warmer/colder than average, and precip might be 200% of average for that day. Look at 5 days combined, including that initial day, and the temps will likely be less than 15 degrees above/below average and the precip might be something like 150% of average for that time frame. Expand the period of study to 30 days at the temps are likely to be 1-3 degrees above/below and precip might be something like 100-130% of average. Go all the way out to a year and it is hard to find an area or even station that is more than 1 degree above/below the average for temp and more than about 110-120% of average for precip."
"No drought lasts forever, they are always broken, it always rains again. No flood lasts forever, the rains always stop and within a period of time, things return to "normal". The same can be said for temps. Cold snaps come and go, so do heat waves. Nothing lasts forever in the weather. "
And this ....
"Another method I like to use is similar to the previously mentioned method, only it looks at what the pervious several seasons have been like not just the past few months, examines them for any anomalous weather and then sees if there is any imbalance that has occurred in the past 5-15 years. If there is some kind of imbalance, then my idea is that the more types of seasons a particular region sees, the greater the chances that it will see the opposite occur. I find that the best way to illustrate things is to give an example and so I will do that here; I probably do not have to tell persons in areas of central WI that the past several winters have been rather poor in the snowfall department. So it can be said that they have had an unusually high amount of low snow seasons in the past several years. So unless the climate is changing in central WI, they have a greater chance that one of the next few or several of the next few winters will be the opposite and provide above average snow."
