Late spring 2018
Having learned of the sun, moon and stars in scripture based on what our Creator tells us in His Word. The scriptural new year begins when the new full moon is under the feet of the Virgin Bethulah. This means April 30th is the first full moon or the first day of the month of Abib. This happens every three years as per the book of Hanok (Enoch). So prepare yourself for the late spring. Trust Yahu'ah יהוה your Almighty Creator through the MessiYah Yahu'shua rather than trusting man. Shalom
I must admitt...
That you got that "late spring" thing right. April 18th, 2018 here in SE MN , 4-7 inches of new snow falling as I speak !
Please let this be over :-(
how to read this chart.
How do you read the Nov. 2017 to Oct. 2018 chart? what is this -8 and -1 stuff? for instance the precipitation in May? a full -1 inches? Someone please help?
The plus or minus 8 is above
The plus or minus 8 is above or below average temps for the month, the plus or minus 1 is above or below average precipitation for the month.
False spring ?
Anyway here in southern MN we can expect another False Spring Day with temps very pleasant for mid February !
So where did "False Spring" originate from? Thanks!
Temperatures
Well, this winter in MN (twin towns) has been well below normal temps across the board. “Average high” of low to high 20s in Jan/Feb has been very elusive- and the almanac forecast was for above average temps.
Let’s hope the yearly forecast continues to be wrong so this summer isn’t 90s and humid after all...
Keep trying, Almanac! I know the science isn’t easy during the Trump years...

I always plan my camping trips around the warmest predicted summer days, so far so good. The accuracy is amazing.
