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.


Figure 2. Morning satellite image of 93L over the Central Atlantic.

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.

Have the Azores ever been put under any kind of Tropical Storm or Hurricane Advisories in the past?


Answered my own question. They have been put under a TS Watch which was upgraded to warning when Gordon (06) threatened them. It's kind of ironic how if this system was named, it'd be named Gordon as well, threatening the same area.

Convection is definitely lacking, but overall structure is great for a TD. I bet this makes hurricane status.

mcluvincane, many of us like fish storms to watch. They can be quite the educational tool and are nice because they don't kill people. Some are in harms way with the new TD, would be silly to no mention it. I like watching fish storms, they are still systems, they are beautiful and unique. Only one to watch at the moment not to mention. Waste of blog space?? Slow day here, any storm is better than no storm.

Quoting VAbeachhurricanes:


So what? just look at it, surrounded by dry air.



All that dryness on WV is subsidence associated with the northern, descending branch of the Hadley circulation that supports the Bermuda High, and is not related to the SAL.

But yes, the convection is still not robust partly because of dry mid/upper level air, and partly because of the SAL.

In the lower levels, the TD8 is in fact finally pulling away from the main area of SAL, which can be seen as the brownish area south of 30N and east of 55W on the RGB image below. You can also see a bit extending southwest out of TD8 and on the outskirts of the circulation.



Ultimately, TD8 is a small island of moist air in a sea of dry air...

Can you imagine if this is true?

Finding A. Greater Management Attention to Data Quality Needed To
Report Climate Change Program Results Accurately
Of the 196 climate change programs, totaling $34 million, selected as part of the original
sample, OIG determined that for four programs7 (21 percent), OES/EGC did not always ensure
the quality and supportability of data used to report programmatic results in the FY 2010 Foreign
Assistance Performance Plan and Report (PPR).8 This occurred because OES/EGC did not fully
implement the guidance for conducting DQAs9 to help ensure that the data used to report results
in the PPR were complete, accurate, consistent, and supportable. For example, OES/EGC did
not always implement the six-step sample methodology provided by the Office of U.S. Foreign
Assistance Resources to include step 3, which required a review of data collection methodologies
used by recipients and verification of what recipients provided against raw data sources.
As a
result, the programmatic results reported by OES may not always be reliable for the purpose of
gauging whether climate change indicators are being met.

RitaEvac oh Lordy. Talk about a can of worms about to be opened up if that's true. Think that's true for the government in general though with almost any program. Lot of folks going to be sitting in front of an oversight committee soon. Just another brick in the wall that'll set back planning and enacting those plans in the future to combat the effects of GW. Wonder whom that'll benefit?

Oh, ice loss is now the same ol' same ol'. What I was referring to was FREAKY weather speeding up the ice melt as possibly also joining the NewNormal.

O lordy, from FOX btw...


EXCLUSIVE: State Department oversight of climate change spending abroad is a mess, watchdog reports



Inadequate oversight, lax bookkeeping, sloppy paperwork, haphazard performance agreements and missing financial documentation have plagued U.S. State Department spending of tens of millions of dollars to combat climate change, according to a report by States internal financial watchdog and the problem could be much, much bigger than that.

Evidence for Rainfall-Triggered Earthquake Activity

Fluids are known to be of major importance for the earthquake generation because pore pressure variations alter the strength of faults.
Thus they can initiate earthquakes if the crust is close enough to its critical state.

it most likely will affect to azores and it is fully tropical i dont see why they wouldn't name it. Just say this becomes the worst storm the azores have ever seen and just because its not in the deep tropics they dont deserve to have a name to remember it by?
