Mendoza recorded its all-time high yesterday, definitely a strong/prominent record nationwide as it's the 4th largest city of Argentina. It has a rather complicated history regarding to the changing location of the various stations within the city, which also has several micro-climates due to the local geography. Mendoza Airport: 44.9C Mendoza-San Martín Park Observatory: 41.8C Both figures are all-time highs for their respective locations. Previous records were 44.4C in the AP station and 40.2C in the Park Observatory, both happened in 2003 on the same day. The old downtown station, opened in the late 1800s and replaced by the Park Observatory circa 1950, recorded its all-time of 42.7C in 1943. The same day, the Old Plumerillo Air-Base only hit 42.2C. The latter was located very close to the modern AP and I think it's fair to put them in the same record timeline. The modern Observatory, though, it's located in a somewhat hilly and heavily forested park on the west side of the city, at higher altitude, it's very moderate and definitely not comparable with the old city station.
 The extreme heat was caused by the Zonda wind, a kind of foehn typically seen in Western Argentina. Interesting to see how the dew point started out at around 20C, and then plummeted to -23C thanks to such winds.
Yesterday there was also a massive thunderstorm in Buenos Aires (a lot of fallen trees) and a tragic one in Bahía Blanca, with 13 dead due to a falling roof where an event was taking place. In both cities, gust winds of +100 km/h were recorded. San Juan, 150 km north of Mendoza, recorded 46.0C, the highest temperature in the country, but it was not an all-time high for this place, whose record is 46.7C.

Looks like it's gonna be a blowtorch for Siberia and much of Asia. Gfs 12z showing warm Atlantic air being thrust deep into Siberia pushing Siberian high to the east, thanks to high pressure over Europe pulling warm air and deflecting low pressure systems into Russia. ECMWF seems to agree with this too.

Hurricane Mcghee getting initialized at the immediate coast (and offshore) as of this PM   Impressive rain totals for winter should they come to fruition Near-record low SLP as well |

Cairns major flood after 1 metre of weekend rain ( source: Weatherzone )  A tropical deluge in the wake of Tropical Cyclone Jasper has caused the largest flood in more than a century in the Cairns region of northern Qld. Tropical Cyclone Jasper made landfall along Qld’s North Tropical Coast on Wednesday, December 13. Since then, the remnants of Jasper have been hanging around far north Qld, with an associated coastal trough also developing along the state’s North Tropical Coast.  This coastal trough has produced immense rainfall over the last couple of days. A rain gauge at Myola, located on the Barron River to the northwest of Cairns, received more than 1056 mm of rain between 9am AEST on Saturday and 9pm Sunday. This brought the site’s running 5-day total (9am Wednesday to 9pm Sunday) up to 1930 mm. One of the remarkable things about this weekend’s rainfall is how persistent and intense it has been around the Cairns and Daintree regions. A rain gauge at Black Mountain, located south of Craiglie, reported a whopping 672 mm during the 12 hours ending at 3pm AEST on Sunday. This is similar to the 665 mm recorded at Myola in the 12 hours ending at 6pm on Sunday. If valid, both observations beat the previous record for the highest 12-hour rainfall on record in Qld, which was 617 mm at Paluma in January 1972. The rain from Jasper and the more recent coastal trough has cause widespread major flooding along Qld’s North Tropical Coast. The Barron River at Myola exceeded the major flood level of 10 metres early on Sunday morning and had reached as high as 14.09 metres by 8pm AEST. This is close to 1.5 metres higher than the 1977 flood and the highest peak at this location since 1913.  he flooding from this weekend’s phenomenal rainfall has inundated homes and airports, with numerous emergency alerts, severe weather warnings and flood warnings issued. Be sure to check the latest warnings for the most up-to-date information as this event continues to evolve. You can also find breaking news updated on the ABC’s live blog. |

Two Qld locations register Australia's 3rd and 4th wettest day on record, provisional data shows ( source: Weatherzone )  Some of the heaviest rain ever observed in Australia has hit Queensland’s North Tropical Coast during the last few days, resulting in widespread major flooding and landslips. Rainfall has been relentless over northeast Qld ever since Tropical Cyclone Jasper made landfall near Wajul Wajul on Wednesday, December 13. This 5-day spell of wet weather was exacerbated over the weekend by a slow-moving coastal trough being fed by a persistent stream of tropical moisture. Provisional data collected by Bureau of Meteorology rain gauges shows that two locations in Qld may have just received the 3rd and 4th highest daily rainfall on record in Australia. There were also four locations that beat the previous national daily record for December. During the 24 hours to 9am on Monday, December 18, Bairds registered 870 mm and nearby Diwan recorded 829 mm. If these observations are valid, they are the 3rd and 4th heaviest daily rainfall totals on record in Australia. The only wetter days were 878.3 mm at Finch Hatton on February 18, 1958 and 907 mm at Crohamhurst on February 3, 1893.  Prior to this event, the heaviest daily rainfall even observed in Australia during December was 678 mm. This mark was eclipsed by five locations during the 24 hours to 9am AEST on Monday, December 18: 870mm at Bairds 829 mm at Diwan 714 mm at Mossman South * 701 mm at Yandill 700 mm at Whyanbeel Valley *Mossman South did not record rainfall during the previous 24 hours, so this may be a 48-hour accumulated total As of 9am Monday, a few places had seen more than two metres of rain over the last five days (9am on December 13 to 9am December 18). This included 2166 mm at Black Mountain, 2118 mm at Bairds and 2025mm at Myola. To put this rain into perspective, it exceeds the annual averages of Cairns (2000 mm) and Darwin (1721 mm). Within these colossal multi-day totals were some shorter periods of very intense rainfall that caused rapid river level rises, flooding and landslips. At least two locations appear to have broken Qld’s 12-hour rainfall record, with Black Mountain receiving 672 mm and Myola registering 665 mm from Saturday evening into Sunday. These were both above the state’s previous 12-hour record of 617 mm from Paluma in January 1972. They are also higher than the annual averages of Melbourne (648 mm) and Adelaide (527 mm). This vast amount of rainfall has been caused by the remnants of Ex-Tropical Cyclone Jasper lingering over western parts of the Cape York Peninsula. Over the weekend, monsoonal winds from the Northern Hemisphere wrapped around the northern and eastern sides of Jasper, delivering a concentrated surge of tropical moisture and convection to Far North Queensland.  The data mentioned in this story is provisional and will need to be quality controlled by the Bureau of Meteorology. |

Nice and intense coastal storm will impact here late tonight and tomorrow. 2.5-3" of rain and wind gusts of 60mph expected. High wind warnings up here, and flood watches inland where the rains could exceed 5", upsloping will help. Mild airmass and with southeasterly winds, temps could reach 60ºF tomorrow.

Decent temperature inversion today here in Zagreb. Temps measured at 7 am: Airport (107 m/351 ft asl): -3C Maksimir (123 m/ 403 ft asl): -2C Grič (157 m/515 ft asl): 0C But at the station located on the Medvednica mountain: Puntijarka (957 m/3140 ft asl) : +11C!
So it has been warmer up there in the mountain than down here in Zagreb these days. |

This is why I generally take litte if any notice of long range forecasts... especially in the tropical north ( err... far North QLD in particular with biblical rainfall totals in the wake of TC Jasper ! )  |
