The June 2012 U.S. heat wave: one of the greatest in recorded history

Intense heat continues to bake a large portion of the U.S. this Tuesday, with portions of 17 states under heat advisories for dangerously high temperatures. The heat is particularly dangerous for the 1.4 million people still without power and air conditioning due to Friday's incredible derecho event, which is now being blamed for 23 deaths. The ongoing heat wave is one of the most intense and widespread in U.S. history, according to wunderground's weather historian, Christopher C. Burt. In his Sunday post, The Amazing June Heat Wave of 2012 Part 2: The Midwest and Southeast June 28-30, Mr. Burt documents that eighteen of the 298 locations (6%) that he follows closely because of their long period of record and representation of U.S. climate broke or tied their all-time heat records during the past week, and that "this is especially extraordinary since they have occurred in June rather than July or August when 95% of the previous all-time heat records have been set for this part of the country." The only year with more all-time heat records than 2012 is 1936, when 61 cities of the 298 locations (20%) set all-time heat records. The summer of 1936 was the hottest summer in U.S. history, and July 1936 was the hottest month in U.S. history.

According to wunderground analysis of the National Climatic Data Center (NCDC) extremes database, during June 2012, 11% of the country's 777 weather stations with a period of record of a century or more broke or tied all-time heat records for the month of June. Only 1936 (13% of June records broken or tied) and 1988 (12.5%) had a greater number of all-time monthly June records. I expect when NCDC releases their analysis of the June 2012 weather next week, they will rank the month as one of the top five hottest Junes in U.S. history.


Figure 1. Across the entire Continental U.S., 72% of the land area was classified as being in dry or drought conditions as of June 26, 2012. Conditions are not expected to improve much over the summer: the NOAA Climate Prediction Center’s latest drought outlook shows much of the U.S. in persistent drought conditions, with very few areas improving. The rains brought by Tropical Storm Debby did help out Florida and Georgia, however. Image credit: NOAA Environmental Visualization Laboratory.

The forecast: hot and dry
July is traditionally the hottest month of the year, and July 2012 is likely to set more all-time heat records. The latest predictions from the GFS and ECMWF models show that a ridge of high pressure and dry conditions will dominate the weather over about 80 - 90% of the country during the next two weeks, except for the Pacific Northwest and New England. This will bring wicked hot conditions to most of the nation, but no all-time heat records are likely to fall. However, around July 11, a sharp ridge of high pressure is expected to build in over the Western U.S., bringing the potential for crazy-hot conditions capable of toppling all-time heat records in many western states.

The intense heat and lack of rain, combined with soils that dried out early in the year due to lack of snowfall, have led to widespread areas of moderate to extreme drought over much of the nation's grain growing regions, from Kansas to Indiana. The USDA is reporting steadily deteriorating crop conditions for corn and soybeans, and it is likely that a multi-billion dollar drought disaster is underway in the Midwest.

The wunderground Extremes page has an interactive map that allows one to look at the records for the 298 U.S. cities that Mr. Burt tracks. Click on the "Wunderground U.S. Records" button to see them.

Quiet in the Atlantic
There are no threat areas to discuss in the Atlantic, and none of the reliable computer models are developing a tropical cyclone over the next seven days.

Have a great 4th of July holiday, everyone, and I'll be back Thursday with a new post.

I don't often advertise my personal life on here, but I am in an enormous predicament at the moment that I see no way out of. Circumstances are so bad, in fact, that I may temporarily have to withdraw from the blog (but I'll try and remain strong).

As everyone probably knows, I'm bisexual. I've stated this before. Everyone also knows I work at Walmart. Well, there's this guy in electronics who's gay. Name's Nick. He worked with my dad a few years ago before he quit Walmart (he was the ZMS over that section of the store). About a week ago, his best friend Marah told me "I don't know how to say this, but Nick has sexual feelings for you." I said "Uh... okay? I don't know what you want me to say to that." Apparently I wasn't supposed to know, because Nick asked Marah to keep it a secret.

I told my dad about it, figuring he'd eventually forget about it. He didn't. He asked me today if I had talked to him yet, to assure him I wasn't gay. I said "I haven't told him anything because I don't want to make him feel awkward. I wasn't supposed to know in the first place." He says "Well he's gonna feel awkward. You could just tell Marah. Tell her you're neither gay nor bi." I didn't respond to that, because I can't respond. I'm not comfortable approaching Nick and making him feel embarrassed or uncomfortable. Worse case scenario, he'll be mad at Marah. Damaging a solid friendship is not something I am fond of. And I am not comfortable lying to Nick either, because he's my friend.

I know dad's not going to forget about it. He's not stupid. The only way out I can see at this time is to just come out to him. I love him, and don't want him to treat me any different just for being different. *sigh*

Oh, and if anyone's wondering, I don't live with my dad, so I'm not worried about being kicked out of house and home. I'm more worried that a currently superb father-son relationship will be all but destroyed in a single instance. I don't want that.

Honestly, I don't know why I'm telling you guys this. Perhaps it's because I can't talk to my family. I live in the deep south, where being gay is highly frowned upon. But rest assured that I'm not doing this for sympathy or attention. I'm not in the business of flaunting my sexuality. I'm not flamboyant at all.

I'm open to suggestions if anyone has any.

Well I did some thinking, and I have an idea of what I will do. Nothing drastic, so don't worry. I would rather not discuss it though until I see how the situation unfolds. I WILL keep you guys updated, though. I promise. I love each and every one of you. Even you, Cody. ;)

I greatly appreciate everyone's concern and well-wishes. I will try and respond to my numerous WU mails tomorrow.

Until then, I leave you all with a blog I did while thinking. I'm a strong person, I can't let something like this keep me down!

This will be my last post (I won't even lurk) until tomorrow. See ya.

I am gay, coming out was a little difficult but it has to be done. If you are not in danger of losing your housing, there really is no downside. If your father doesn't like it, that's his *choice*. It's not your *choice* to be bisexual. If someone can't love you for who you are, that's not love. If he doesn't like it at first, he'll more than likely get over it, although most don't. I don't live in the South (no where near it), so my situation was a little different. But, I stopped hiding it once I was 16 and ever since then I've never looked back. Don't hide it - it makes things worse than you can imagine. This is your opportunity to have a discussion with your father about this. If you already went to him to discuss the situation with Nick, then you more than likely unconsciously felt that it was time to talk to your father about your sexuality.

Regarding Nick, it's difficult to give advice about personal issues, but you certainly have the option of not addressing it at all. If Marah was not supposed to tell you, pretend like she never did and just ignore the situation for a while and see what happens. It's not necessary to throw yourself in the middle of a drama you do not want to be part of. Conversely, if you also have feelings for him, it could be an opportunity for you to explore your feelings.

It's really hard, I know. You may have heard this numerous times, but there are tons of places in this country where being gay is normal and accepted. Be true to yourself and you will be on the right track.

seems odd that you told your dad about it to begin with... Maybe because you want to get this out in the open with him? If you have a truly superb father-son relationship then I'd think you still would after tellng him. Be sure to give him time to digest it all! Best wishes to you. Back to Lurk mode for me :)
