Rain

Something is wrong, we are getting India’s monsoon weather! Not cool!

Rain rain rain

The weather has definitely changed since I was a kid. June rain every day and August in the 70s! I’m so done with rain!

Weather

Agreed, look so forward to summer and it is so depressing. Cloudy, cool and rainy is nothing to get excited about.

Weather Changing

When I was a kid it started snowing at the end of November and snowed on and off up until end of Feb and now its 60 and 70 degrees up until November and mild in the winter, I always do a big garden and the weather has changed a lot since my youth, Our area keeps getting more rain than normal

Kentucky Spring...

Love our Bluegrass in the spring, meadows are greener, horses have ponies out grazing as warmer temperatures are welcome. Any advise for when it is safe to start lawn seeding or gardens?

The best time to sow grass

The best time to sow grass seed is actually two different times in the year. Early September and Dormant Seeding in January when the ground is hard. I would sow grass at this point, anytime. Soils are still a tickle cool but will warm enough for germination soon.
Cold hardy root crops can go in very soon but gardens can't go in until the projected last frost date. Keep an eye on the weather temps, you may be able to get it in sooner if it stays warm at night.

Bring on Spring

We haven't had much of a winter in the eastern part of the Appalachian mountains, BUT I am ready for spring. Today, as I am writing this, the high was 67 degrees. I am just ready for warm weather where we can swim under waterfalls and in lakes again. I don't much care for the snow. Comment below what state you live in!

My state/Weather

I live in Saltsburg PA. 11 miles south of Indiana PA. Where the Conamaugh river meets the Loyalhanna to form the Kiskaminatis river. Like a mini Pittsburgh. Lol. Last year it rained I believe a record amount of rain. I live in a fairly shaded area. It makes it quite difficult to have a garden. I hope we don't get a repeat of that this summer. I'm wondering how hot it's going to be also.

Summer

I live in southwest ohio and it has rained at least 60% of the time since I moved here almost 2 years ago I just want 80's and sunshine not 60's and rain this isn't Washington state

Rain

It rains every single day. How could it possibly say that there will below "normal" totals.
