April 2 Snow storm!

Hey you guys only said showers. Weather channel and others keep getting forecast wrong. What’s going on. First it was supposed to be less than inch of snow Now 2 to 3 now changed to 4 to 6 along the coast. When can I work on my garden?

Weather & Gardening

The Editors's picture

During the transition from one season to another, it’s especially difficult to say whether a storm will bring rain or snow—and how much of either there will be!

As for gardening, check out our Frost Dates Calculator to see the average date of the last spring frost in your area. This should give you an idea of when temperatures typically begin to warm up. Also take a look at our Planting Calendar to see the best times to start and plant seeds in your area.

Which is the more favorable weather last 2 weeks of July or 1st

Best forecast for no rain last 2weeks July or 1st 2 weeks August for long island ?

Planting

Being that this weather is so bizarre, when can I ACTUALLY plant outside??

ANOTHER No’Easter?

I trust the Almanac. Unfortunately your forecasts for 2017/ 2018 have been accurate so far. After a dismal, rainy summer, followed by an even more dismal fall we hoped for decent, if cold winter weather. It has been awful here. Cold, rainy, snowy and 3 major storms in as many weeks. Horrible weather and the spring forecast isn’t much better. Yuck

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.
