weird weather
We feel your pain, jj. And the biggest surprise in your message is that you’re describing Virginia! Thought for sure you were describing New England. Whatever happens, whatever the weather, remember that we’re all in this together and the only certainty is change. Thanks for taking the time to write.
AN ACT OF WAR
The government agencies with military planes and whatever other planes are being used are blocking out the sun,raining down god knows what chemicals on all of us and destroying our food supply.This is nothing short of AN ACT OF WAR.
JJ... Welcome
Old men complain about the weather. Old women complain about old men. Keep it clean boss. We use this site to teach. Move to San Diego! Thanks.
Looking at third nor’easter.
Wow, I think my indoor starter plants will be fruiting soon!!
indoor plants
Wow—finally some good news! Help them to hang on—spring is coming. (It may not arrive on the equinox but it’s coming!)
Wrong forecast
We’ve had 2 nor’easters in the last 2 weeks....NO mention here. Def disappointed you didn’t get it correct..
northeasters...
Yes, we are, too.
Not Wrong at all
Farmers Almanac called the storms in their extended forecast back in October!! Said that we would have above average snowfall in the month of March and possibly a snow storm in April!! So we will see!! I only trust Farmers Almanac and read months in advance to know what to expect!! Pretty right on the money the last 5-6 years
right on the money
Thanks, Lexi! We appreciate your trust and enthusiasm—s’now joke!
Said it would be cold and stormy
The almanac said unusually warm feb (we hit 80 in nyc) and unusually colder with 4 storms in march. Happened....The almanac cant predict 4 Noreasters. We tune to NOAA and local tv and radio for that!
