Summer is coming ... [a weather thread]

[MasterJedi]

It's going to be hot and sunny all week

Send it this way.

Today, April 20, the 30°C (86°F) were broken for the first time this year ... in Salzburg.

That is the 2nd-earliest date in history (only April 17th, 1934 beat today).

[Ban my account ffs!]

(A picture overlooking the Boundary Waters Canoe Area Wilderness shows springs slow arrival.  It's 52F at the time of this picture, so the melt is on.


The coldest first half of April in Minnesota in decades (I'd have to look through the records... 1950 was probably the last time it was this cold).

All but one of the lakes in the state are still covered in ice.  Lake Pepin which is a natural lake on the Mississippi River saw ice out today.  Ice may still cover many northern Minnesota lakes for the Walleye fishing opener May 12th... the first time in 5 years but only the 4th in the past 40 years (1996, 2008, 2013)

April was the warmest on record here (since 1750).

The month was 5°C warmer than the average of 1981-2010 and 5.5°C warmer than 1961-1990.

The year 2018 so far is 1.1°C warmer than the average of 1981-2010 and 1.8°C warmer than 1961-1990.

Things are not much different in Germany of course:

[100% pro-life no matter what]

We had an unusually cool April.  The average high temperature was only a tad above 66 degrees.  Compared to other recent years:

2017- 77
2016- 75
2015- 73

The warmest day of the entire month was just 83 degrees on 4/3 (and somehow February 23rd is still hanging in there as the second warmest day of the year at 82).  We should finally break 85 this week, probably on Wednesday and Thursday and the long-range forecast shows mostly 80s, so I think we're now finally into the summertime (low 90s will be normal by July and August).

We had the warmest April in recorded history in Shepparton, With an average temperature of 25.8C, 3.8 degrees warmer than average. We also had our warmest April day and night on record, 35.1C degrees during the day, with it only dropping down to 21.7C.

We also had one of the driest Aprils as well, recording just 7.8mm of rain the entire month, with the normal average being 33.8mm

April was the coldest since 1950 in northern MN with the first half the coldest on record.  Temperatures were 4C below normal for the month.  It was also quite dry.

In Philadelphia it was about 2C below normal with roughly average precipitation.

For the US as a whole it was the 7th coldest since 1895 and the coldest since 1996.

The year 2018 so far has the potential of becoming the warmest year on record (since 1700).

The previous record year was 2015, which was 1.6°C hotter than the long-term 30 year average.

Until yesterday, 2018 is 1.7°C too hot. Mostly because April, May and June so far were extremely warm (June by 5°C above the long-term average !).

In fact, we had a stable, sunny weather condition over Central/Northern Europe for the past 5-6 weeks or so, without any really cold days in between. And always heavy thunderstorms and flooding recently.
