Melbourne cold temp
Melbourne will be given a chance to thaw out today following the city's coldest day in 19 years on Thursday.

Yesterday's maximum temperature was just 9.0 degrees in Melbourne as the perfect 'cold day scenario' affected the city. The morning started out at just 3.1 degrees after clear skies allowed the mercury plummet during Wednesday night. Thick cloud then drifted over the city blanketed Melbourne throughout the day, limiting the amount of heating from the sun.

Yesterday's maximum temperature was six degrees below the average for August and came in as the city's coldest day for any month since 1998. The last time a maximum temperature that low occurred during August was in 1970, when the mercury only made it 6.8 degrees.

Daily maximum temperatures in Australia are measured as the highest temperature recorded during a 24 hour period between 9am on two consecutive days. This means the city needed to remain below nine degrees until 9am today for Thursday to go down as its coldest August day in almost 50 years.

The statistic came close to being spoilt this morning as the temperature rose to 8.6 degrees at 8:50am and 8.9 degrees at 9am.

Today is forecast to reach a more pleasant top of 13 degrees in Melbourne. While this is still two below average for this time of year, it's balmy compared to yesterday.

Whilst heatwave 'Lucifer' has seen a number of air temperature records broken in Croatia over the past few days, record-high sea temperatures have also been set on Saturday.

With air temperatures hovering around 40°C for much of the country, there was not much cooling down going on by jumping into the Adriatic Sea.

According to data from the Croatian Meteorological and Hydrological Service, on Saturday the sea temperature on the southern Dalmatian island of Mljet measured 29.9°C at 5 pm, breaking the current record set on 21 July 2015 on the island of Rab of 29.5°C.

In Dubrovnik today the sea temperature peaked at 27.2°C, whilst it was 28°C in Split, Krk, Rab, and Pula. In Zadar, it was 26°C, whilst Hvar's sea temperature was 27°C on Saturday afternoon.

US August 2017 weather forecast
A map shows that a cold front is forecast to sweep across large parts of the country from the east during the first half of August, plunging temperatures below the month's average.
Cooler temperatures are predicted to span much of the eastern part of the United States throughout the month of August.

The first of several spells of below-average temperatures saw shorts exchanged for sweaters across the east of the country over the weekend, with lows of 60F in Chicago and Green Bay on Friday.

Those overnight lows are expected to persist in lands east of the Rockies for the next two weeks, with daytime highs ranging from the upper 70s to the low 80s, according to Weather.com.

Manipulating the southern European heat wave

With the European "Heat wave" running for the last two weeks, I compared temperatures from 2003, 2006, 2007 and this latest bout of heat. The findings are in line with previous heat during the summer months stretching back to the 1950's. The media is making this to be the hottest ever in Europe, when in fact it is not. plus the media conveniently leaves out the cooler than normal temperatures all along the boundary edges of the heat in central Europe, and not even discussing the below normal temperatures in North Africa. The IPCC machine is steaming ahead full bore.

With the media focused on a central European heat wave, the conveniently left out of the same temperature map that Norway, Iceland, Sweden, Denmark, Finland and the deserts of N. Africa are below normal temperatures. Also snow in USA in August comes as a surprise, but Al Gore's ascent from $2 million to $300 million is not a surprise.

It's August and there was snow over Monarch Pass, Colorado

If you're reading this, you're likely from Colorado - so you know that when it comes to weather, our beautiful state has quite a few tricks up its sleeve.

Case in point? These photos of Monarch Pass. Yup - it's kinda snowy up there! And the pics are from Aug. 3. That's in the summer.

Brad Shilling lives in Gunnison and took the photos en route to the seasonal state swim championship in Lamar. When they got to the top of the pass, Shilling says rain turned into freezing hail, and then pea-sized hail.

Other cars started to fishtail and lose control in what he described as "slush-snow-rain."

Ten southern and central European countries have declared a red alert after heatwave 'Lucifer' caused temperatures to skyrocket over 40C, with scientists warning that the extreme heat could end up killing 152,000 people a year by 2100.

Italy, Switzerland, Hungary, Poland, Romania, Bosnia-Herzegovina, Montenegro, Croatia, Slovenia, and Serbia are on red alert, European forecast network Meteoalarm said on Saturday.

Florence's famous Uffizi Gallery was temporarily closed on Friday after the museum's air conditioning system broke down, ANSA news agency reported.

Greece, Spain, Bulgaria, France, Macedonia, Slovakia, and Moldova have issued orange alerts to stress the potential for worsening weather conditions.

At least two people have died from the heat, one in Romania and one in Poland, Reuters reported, adding that many more have been taken to the hospital for sunstroke.

"In two hours of my shift today I saw four people fainting on the street and complaining of heat exhaustion," a traffic warden told Reuters in Belgrade.

Rare 'heat burst' event causes overnight temperature spike in Vacaville, California

Nightfall didn't bring much relief from the heat for residents in Vacaville thanks to a rare weather phenomenon.

Vacaville suffered through high temperatures of 108 degrees on Thursday, according to the National Weather Service. By 8 p.m., temperatures had dropped down to the low 80s - like what you'd usually expect to happen when the sun goes down.

However, after bottoming out at 80, temperatures actually started to shoot up as the night progressed.

By midnight, temperatures had spiked at 95 degrees.

NWS says the bizarre temperature spike is due to a rare event called a "heat burst."

Much like downburst, a heat burst is usually associated with decaying thunderstorms. Heat bursts are basically the inverse of a downburst - instead of cool and moist air, hot and dry air is rushed toward the surface.

7 unusual weather events noted by US meteorologists in late July

July is wrapping up with several unusual weather events.

Among them are several rainfall extremes, strange tropical cyclone interactions and out-of-season conditions.

Here's a look at what we've seen so far and what's to come.

1. A Rain Event That Had a 0.1-Percent Chance of Happening

Abundant tropical moisture fueled a rare rain event in Harrisburg, Pennsylvania, on the evening of July 23.

Harrisburg International Airport received 4.27 inches of rain in a single hour, from 5:56 to 6:56 p.m. EDT. A rainfall event of this magnitude in Harrisburg has just a 0.1-percent chance of happening in a given year, according to data from NOAA.

The total rain for the day at Harrisburg International Airport tallied up at 4.71 inches. This now stands as the wettest July day on record, and the fifth-wettest day overall for any month of the year at that location.

This downpour was extremely localized. Harrisburg's Capital City Airport, just a few miles to the northwest, saw less than a half-inch of rain during the same evening.

Greenland breaks July cold record second year in a row, volcanic steam vents open which media downplays

For the second year in a row Greenland's Summit station has broken all previous records. This newest record in July 2017 was even a Northern Hemispheric all time cold record for July @ -33C. When forecasting changes and intensification of the Eddy Grand Solar Minimum, I look for trends that are beginning to increase from 2015 forward as the cooling was postulated to begin at that time across the planet. Along with this increased volcanism and reawakening volcanoes dormant for 400, 800 or 1200+ years. With Greenland we see both data sets. I present to you my findings and also say that Greenland will slow significantly its summer melting from this year forward.
