My OFFICIAL 2010 U.S. SUMMER TEMPERATURE AND PRECIPITATION OUTLOOK (with MAPS)

Posted By: TheMaineMan  Posted On: May 20th, 2010  Filed Under: Weather

As promised, here is my forecast.

I think the maps are rather self-explanatory, but here are a few things I'd like to add:

- Temperatures in most parts of the country will be quite volatile… expect very frequent heat waves and cool spells compared to normal. However, certain patterns will clearly dominate at specific times.

- Precipitation tends to favor the south to begin and the north to end. Tropical activity will make August particularly wet in the southeast, and the northeast if tropical depressions make it up there.

- The first half of September will look a lot like August, but the second half will be a blowtorch amongst most of the country, lasting into early October. Beginning in mid-October, the La Nina pattern will take over much of the country, leading to generally cool, wet conditions in the north and warm, dry conditions in the south minus the SE due to tropical activity.

- Gardening may be difficult due to excess rain or excess drought at particular periods in the summer. Try to cope accordingly.

- Much like the winter and spring, I expect this to be a SUMMER OF EXTREMES, especially in the NORTH. Record high temperatures and record low temperatures may be set (although at different times). Maine has not seen 100 F since the 1970s, but this may be the year when it returns, especially in late June or July. In August, I expect the south to be very hot, possibly setting records down there as well.

Feel free to ask questions and post comments!

    do you think that fort wayne, IN could see a one hundred degree day this summer. i have never seen a one hundred degree day here. i want to see one

    Sweet a$$ maps dude. And awosme look out i believe it 100 percent without no doubts. Homemade maps are allways the truth maps because it comes from the heart. The ones with all the fancy designes are the ones that have to be tweaked monthly. Yous did a very good job maineman.. Have a great weekend all!

    I'm convinced we'll see a 100 degree day before the summe ris done blizzard..

    If ever there was a summer to hit 100 in the north, this may be it. I'm not sure what the records are in Indiana, but some of them may be challenged. Just getting into the mid or upper 90s would break a lot of records here.

    In the plains, I wouldn't be surprised at all to see 100+, maybe even a run at 110 at some point.

    I think these will do fairly well, good job! I'll be content as long as I don't have a repeat of last summer. Some of our grass flooded so long that it was killed. It's hard to do that with fescue grass.

    I have 2 questions to ask either to the maineman or to wjp 1 of them is that i know its common and late spring and ealy summer too see a severe weather or tornado outbreak in the great plains. but where i live we've seen our fair share of severe weather and tornado outbreaks. And i live in nw.ohio. I guess my first question is it because of the weaken El nino that this is happening? And my last Question is that do guys have any clue how strong this la nina is going to be when she gets going?

  8. TheMaineMan says:

    It seems like a bad year for severe weather… Maine has already had one confirmed tornado, and our annual average is two. And it's only early June!

    Last year we had six though, but last summer was also a weak Nino I think?

  9. lynnbalderas says:

    i totally dis agree with the la nina thing

  10. TheMaineMan says:

    ENSO  models are now showing a potential “bounceback” in autumn, but I think that's only because they overstate the plunge into negative conditions in the first place. I think it will stay neutral throughout the summer, turn slightly negative in the autumn, then maybe become a weak Nina in the winter.
