So weird dealing with pulse storms in May, this is more like a mid to late June into August pattern.

If you look at the severe weather over the past week or two, it really is something you'd see in July or August. I like summer weather and the storms that come with, but I want to have May weather in May. Where's the dryline supercells, the 2-3 day tornado outbreaks, the Reed Timmer screaming "wedge" at every tornado he sees?

The tornado activity this year is blowing my mind. If we don't get some major events in June, October, or November, this year will live in infamy for the lack of tornadoes for decades.

On average, summer is lengthening and winter is shortening so June weather in May (very likely what we're currently seeing) will probably happen more often than not in the future.


Not for us in the North East, we just went through 6 months of Winter and they are getting longer and longer stretching into April now, the complete opposite of what you guys are having in the MW. Our growing season on Li has been pushed back at least a month the past 10 or so years. Whats even worse is we go right into Summer, Spring is just an afterthought for the most part and maybe, if we are lucky, lasts 2 or 3 weeks before the 3 H's are a daily haunt.

QUOTE(Gnutella @ May 26 2018, 08:19 PM) *
Ironically, Pittsburgh reached 100F in 1995, but Kansas City, Indianapolis, Cincinnati and Washington DC did not.

I think the reason why Pittsburgh often gets low-balled in heat waves is because the official observations come from a station located 13 miles northwest of the city at about 1,200' above sea level. The extra elevation and the relative lack of an urban heat island effect in the vicinity of the station can rub anywhere from two to five degrees off the temperature. (There's virtually zero development to the west of the station.)

Up until June 1948, official observations in Pittsburgh came from a station in Allegheny Commons that averaged 14 days of 90F temperatures per year. Had official observations come from there until the station went offline in 1979, then you could add August 27, 1948 and September 3, 1953 to Pittsburgh's list of "official" 100F days, and you could also subtract 1976 and 1979 from the list of summers when Pittsburgh failed to reach 90F.


The station is far from the city. Very annoying.

...HEAT ADVISORY REMAINS IN EFFECT UNTIL 1 PM CDT MONDAY...
...EXCESSIVE HEAT WATCH REMAINS IN EFFECT FROM MONDAY AFTERNOON
THROUGH MONDAY EVENING...

* TEMPERATURE...Mid 90s are still expected late this afternoon.
Temperatures will only cool into the low to mid 70s tonight,
especially downtown, so the Heat Advisory has been extended
through the night. Highs Monday will likely reach the upper
90s. The humidity will also be higher than today, resulting in
peak heat indices possibly in the lower 100s by afternoon.

* IMPACTS...Heat illnesses are possible for those active
outdoors or those susceptible to heat illnesses, such as
children and the elderly.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Heat Advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. Drink plenty of fluids...stay in an air-conditioned
room...stay out of the sun...and check up on relatives and
neighbors.

Take extra precautions...if you work or spend time outside. When
possible...reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

That's crazy.

Second 90 degree day in a row. 1 more for an official heat wave here. It's crazy we're this close to a heat wave and it's not even summer.

Currently it is 89 degrees at the airport. Do you know how aggravated I will be if we can't just push up one more degree! We still have time.

Edit: 91 today! 1st 90 degree day.

I know the feeling. So frustrating when it's 89 degrees and I can't add it to my tally of 90 degree days. It's ridiculous how many times that's happened.

That's like the story of Pittsburgh weather, always just short, lol.

This was actually the first 90 degree day in May since 2012. Wonder if that means anything? Probably not, but interesting.

For what it's worth, Pittsburgh has reached 90F in May in the following years since 1900:


1900
1902
1904
1911
1914
1919
1925 (April)
1929
1936
1939
1941
1942
1949
1962
1987
1991
1993
1996
2006
2011
2012

Average: Once every 6 years


In an average summer period, Pittsburgh averages 10 days of 90F temperatures, 1 day of 95F temperatures, and a maximum temperature of 94F. Here's how many 90F days Pittsburgh had in each of the summers above:


1900: 36
1902: 12
1904: 7
1911: 23
1914: 21
1919: 14
1925: 13
1929: 7
1936: 26
1939: 15
1941: 18
1942: 5
1949: 19
1962: 13
1987: 19
1991: 22
1993: 23
1996: 3
2006: 6
2011: 18
2012: 20

Average: 16 days


Here's how many 95F days Pittsburgh had in those summers:


1900: 12
1902: 0
1904: 0
1911: 6
1914: 0
1919: 2
1925: 3
1929: 0
1936: 8
1939: 1
1941: 4
1942: 1
1949: 2
1962: 1
1987: 0
1991: 2
1993: 4
1996: 0
2006: 0
2011: 2
2012: 6

Average: 3 days


And here's the maximum temperature in Pittsburgh in those summers:


1900: 98F
1902: 93F
1904: 91F
1911: 100F
1914: 94F
1919: 96F
1925: 95F
1929: 93F
1936: 102F
1939: 95F
1941: 96F
1942: 95F
1949: 97F
1962: 95F
1987: 94F
1991: 95F
1993: 98F
1996: 90F
2006: 91F
2011: 96F
2012: 98F

Average: 95F


Based on the data above, Pittsburgh is more likely to have a hotter-than-normal summer in 2018, though there's no guarantee of it.
