I’m a definite minority in that I LOVE cook, rainy weather. If I could relocate to a colder climate I would, except I would miss my grandkids so much. The older I am the less I tolerate heat and humidity. I absolutely LOVED our wet, gray, rainy Spring-extension of Winter. I eagerly look forward to September every year

Me too ! I absolutely LOVE

Me too ! I absolutely LOVE cold weather and love to cook chicken soup and bake apple cinnamon pies . Can't stand July

Cool grey weather.

I also love it. I could gladly eliminate June July and August from the calendar except for the shorts and bikinis, I'd miss those. Otherwise I love a nice cool grey day, it sort of makes me feel like anywhere I go im not under the spot light and wherever I'm at I'm with the person that's with me and were in our own cozy, intimate little environment away from everyones spying eyes. Even out shopping, imagine that! Id sit and lay around with you and eat your home made chicken noodle soup (love that stuff) and pies (yummy) and watch fun movies with you all day long. RRrrrr. Cool grey days, are if you think about it, actually hot! Good day. Jpol.

Yup. We just had nearly a

Yup. We just had nearly a week of extreme heat. We've had a lot of rain this spring too, making planting late.

To be fair, predicting is not an exact science.
