Hottest rain on record? Rain falls at 115°F in Needles, California

A searing heat wave rare even for the Desert Southwest sent temperatures soaring to record levels on Monday, with Needles, California tying its record high for the date of 118°F (47.8°C). The temperature might have gone higher in Needles, but a thunderstorm rolled in at 3:20 pm, and by 3:56 pm PDT, rain began falling at a temperature of 115°F (46.1°C). Most of the rain evaporated, since the humidity was only 11%, and only a trace of precipitation was recorded in the rain gauge. Nevertheless, Monday's rain at 115° in Needles sets a new world record for the hottest rain in world history. I don't think many people were outside to experience to experience the feeling of rain falling at 115°, but if they were, it must have been an uncomfortable, sauna-like experience! Thanks go to Dr. Warren Blier of the NWS Monterey office for pointing out this remarkable event to me.

It is exceedingly rare to get rain when the temperature rises above 100°F, since those kind of temperatures usually require a high pressure system with sinking air that discourages rainfall. Monday's rain in Needles was due to a flow of moisture coming from the south caused by the Southwest U.S. monsoon, a seasonal influx of moisture caused by the difference in temperature between the hot desert and the cooler ocean areas surrounding Mexico to the south. According to weather records researcher Maximiliano Herrera, the previous record for hottest rain, which I blogged about in June, was a rain shower at 109°F (43°C) observed in Mecca, Saudi Arabia on June 5, 2012 and in Marrakech, Morocco on July 10, 2010. The 11% humidity that accompanied Monday's rain shower at 115° in Needles was the lowest humidity rain has ever occurred at anywhere on Earth in recorded history, according to Mr. Herrera.

A "very rare" heat wave for Phoenix
The heat wave that brought Needles' record hot rain has broken an exceptional number of heat records in Phoenix, Arizona the past two weeks. According to the Phoenix NWS office, the "almost unbearable heat" of the first two weeks of August is a "very rare" event, and August 1 - 14, 2012 was the warmest such 2-week period in city history. The average temperature on August 6 - 13 was 100°F or higher each of the eight days, tying the record for most consecutive days with an average temperature of 100°. The temperature peaked at 116° on August 8, just 6° below Phoenix's all-time record of 122° set on June 26, 1990. The forecast for Phoenix call for a bit of relief--highs are expected to be a relatively modest 105° today, and down near 100° by Friday.

93L close to tropical depression status
A large tropical wave (Invest 93L) is located in the Central Atlantic about 700 miles east of Bermuda. Satellite loops this morning show a surface circulation has formed, and heavy thunderstorm activity has increased to the point where 93L should be considered a tropical depression, if the heavy thunderstorms can persist through this afternoon. Wind shear is light, and ocean temperatures are warm, near 28°C. The latest Saharan Air Layer Analysis from the University of Wisconsin shows that 93L has moistened its environment considerably, and dry air should no longer be a significant impediment to development. The 8 am EDT run of the SHIPS model predicts that wind shear will remain in the low range through the weekend, and I expect this system will become Tropical Storm Gordon by Friday. The storm will not affect Bermuda, but residents of the Azores Islands should keep an eye on 93L, which could pass through the islands as early as Sunday night. In their 8 am Tropical Weather Outlook, NHC gave 93L an 80% chance of becoming a tropical depression by Friday morning.

Elsewhere in the tropics
In the Gulf of Mexico, a fall-like cold front is expected to stall out early next week, and the GFS model is predicting something could start to spin up near the Texas/Mexico border on Monday. Wind shear is predicted to be low to moderate, and cold fronts stalled out over the Gulf of Mexico often serve as the seed for tropical storms.

Most of the models predict development of a new tropical wave off the coast of Africa 6 - 7 days from now.

Taz, you're exaggerating the effects of El Niño, yes there will be more shear, but that doesn't mean nothing will form. Go take a look at 2006 and 2009.

Hurricanes formed in both seasons after this date and both had developing El Niño. The only way the season sould suddenly die completely, without hope for any swirl out there would be the formation of a 1997 intensity El Niño, which at the moment is very unlikely.

The reason I called this season awesome thus far is b/c of the notable ABSENCE of those types of storms doing just that.

Oh let the sun beat down upon my face, stars to fill my dream
I am a traveler of both time and space, to be where I have been
To sit with elders of the gentle race, this world has seldom seen
They talk of days for which they sit and wait and all will be revealed


Some folks thrive on calamity, and cheering it on has become more of a spectator Sport one could say.

Taz you have been saying that since after Debby, El Nino is in no way fully impacting the basins yet. It will be about middle september before El Nino completely rears its ugly head, even then it wont be a very strong El Nino. Anyway I can guarentee there will be more storms this year, Its way to early to have the season end.

118 Patrap: [quoting a news article]"The convention will also include approximately 15,000 credentialed media an international press corps second only in size to this summer's London Olympic Games"

Why? The last RepublicanConvention at which anything unplanned was allowed to occur was in 1964. The last DemocraticConvention at which anything unplanned was allowed to occur was in 1980.
And other than commentators interviewing each other, not much has happened since at either convention. Even delegate speeches aren't covered... except partially for officially pre-approved speeches by official keynote speakers.
And even that partial coverage is swamped by commentators "interpret"ing "what was just said" instead of allowing the public to hear it.

Kinda like Olympic coverage: everybody knows that folks tune in to watch commentators talk to each other. It ain't as if anybody would tune in to watch the sports.

You hit the nail on the head with that one. everybody at least has some conection with trade on the Mississippi. If there is no trade everybody gets hit!
Hard to think that about 18 months ago we were fighting over what would happen if the Mississippi changed course due top excessive rainfall and the opening of the sluices which Pat posted such amazing photos of.
Now we have the opposite situation, along of course with a lot of other opposites and bad for humans situation's.
You got what:-
Rainfall at 46.1/C in California, you also got rainfall at 15/C in Alert airport, just south of the North Pole. We got fun and games with a possible hurricane coming in over the Azores towards Europe,of all locations.
To cap all this its only the 16th of August and Planet reforming has only just begun!
Wait till the main movie gets on the screen a bit later on, this is only the Commercial news break!

yes. Media must interpret for the sheople.

It's a sad state of affairs.

The ignorant can't understand the issues anyway, whilst the somewhat educated don't get the real facts to make a decision for themselves anyway, so both are likewise screwed.

MilesDyson, I agree with it being a good Tropical season so far. I know that posters here are very enthusiastic with all kinds of weather and there development but I know they do not want any damage.

But it would be great if we had numerous rain storms or small TS's hitting all of our drought areas lightly and frequently.

Maybe they don't want to scare people, since the 26C mark is above the old record for some longitudes, and only a few miles south of the old record for the U.S. coastal areas near New Jersey and New York.

I can't imagine what other reason they'd have for removing that aspect of the graphic, since it's been here for as long as I've ever visited this site, which is around 5 years now...

was there ever any more information, data or repercussions due the storm that was churning up the arctic ice/waters a couple weeks back?

Skye posted this link to an article at the National Snow and Ice Data Center web site.

"... the effects of an individual strong storm, like that observed in early August, can be complex. While much of the region influenced by the August cyclone experienced a sudden drop in temperature, areas influenced by winds from the south experienced a rise in temperature. Coincident with the storm, a large area of low concentration ice in the East Siberian Sea (concentrations typically below 50%) rapidly melted out. On three consecutive days (August 7, 8, and 9), sea ice extent dropped by nearly 200,000 square kilometers (77,220 square miles). This could be due to mechanical break up of the ice and increased melting by strong winds and wave action during the storm. However, it may be simply a coincidence of timing, given that the low concentration ice in the region was already poised to rapidly melt out."
