Flagstaff snow dayz

Got 5” snow May 2, 2018 in Flagstaff AZ. We’re at 7000 ft elev. but on the volcano above they got 2 ft. 80 today, weird weird beginning of spring.

Wisconsin snow April 2010

Wow snow and more snow. parts of Wisconsin look like December instead of April... farmers watching out for birthing calves and others watching the fruit trees and grapes.. will we have Spring only Mother Nature knows for sure..

Snowed “south hill” Spokane

Cold, lighter snow less then 1/4 inch, just a dusting all around the area today. Currently 32* with high of 42* expected.

Under 4 feet of snow here

North Idaho, Mar 5,2018, 13f last night, 4ft snow on ground, snowed 1 inch last night. We has rain and sping like conditions 3 weeks ago only to get hammered with more snow.

Looks right to me.

In my area this is completely accurate. I love the Farmer's Almanac and have relied on it for decades. Thanks!

Feb weather

if I read this right it shows Feb 2018 as a bit warmer than usual?? On Feb 20th we are shattering the record low temp set back in the 50's....tonight's forecast -26.....hurry up summer??

Unusual Prediction

We have been quite dry, and temperatures are very nice for February. Maybe next week we will see snow? Maybe a false snow. Dare climate change, too bad it can't be predicted more accurately. If that were the case, there would be many meteorologists out of jobs.

Wrong

Extremely rare to have an accurate weather forecast. Best to look at Doppler radar yourself and forcast your own weather. Thanks for listening.

Region 13

Reno looks to be in the middle of region 13, so are we north or south?

Sorry but.... Wrong.

Yea I would be great if winter was like this, but it's January 18th and 51°f outside and we haven't had snow scince Christmas, and even then it wasn't much. Interesting prediction but incorrect, mabey next year.
