Some quotes from netweather right now: "temp is firmly sat at 11C and again it feels cold in the breeze. Plenty more of this to come but without the sun and more rainy. Going to be a horrid spell." "Some utterly atrocious charts being churned out again this morning, lots of days struggling to reach 10c next week" - this guy lives in the south "On saturday I had a few friends over and we played some cards in the garden with some drinks - as soon as the sun began to set around 8pm, we had to move inside because the hurricane force easterly was absolutely frigid. It's so weird that even an evening temperature of like 8 degrees would feel positively balmy right now. I honestly don't remember anything like it and it's thoroughly depressing"
"The outlook really is absolutely miserable today. Cold, unsettled and absolutely no sign of even average temperatures well into May." Fuckin shitey blighty! I'd have thought that most would welcome a continuation of March for another 3 months on there? If it's warm in direct sunlight with no breeze, but uncomfortably cold in the shade or in any breeze, then it's not warm enough! |

I calculated the average conversion factor that the UKMO use to convert Heathrow's raw sunshine hours to something meaningful that can be compared to other places. There is some minor variation but this is the average of the period 2006-2020. flamingGalah any input? Jan: 1.0756 Feb: 1.0798 Mar: 1.0802 Apr: 1.0896 May: 1.1238 Jun: 1.1408 Jul: 1.1290 Aug: 1.1225 Sep: 1.0990 Oct: 1.0914 Nov: 1.0768 Dec: 1.0678
*After converting June 2016's sun hours, it is still the cloudiest June on record.
**The August sunshine collapse appears to be over. Augusts 2007, 2013, 2016 and 2019 were slightly sunnier than average.

Shoutbox started talking about extreme snowfalls and hail and the most frozen precip that could fall in a given amount of time. I'm curious. I know 10 cm of snow can fall in an hour. What about 20cm? There are some records for this for rainfall but snow is harder to measure. Just how fast can snow accumulate? With some countries not measuring snowfall this kind of record won't be perfect but neither are the records for heaviest rainfall.
A severe hail storm could accumulate hail faster than snow, but the NWS doesn't count hail the same way as snow. Some articles about how snow and hail can be measured. The snow depth section explains what a "trace" of snow cover means. Some stations report a trace for longer than others in the spring. Measuring patchy snow depth is a judgement call in some cases.
Hail: Note: Hail accumulation is not entered with snow and ice pellets. Hail accumulation is entered in the ?/remarks/? section with the amount and diameter (inches and tenths) of the stones.
Snow Depth:
Frequently, in hilly or mountainous terrain, you will be faced with the situation where no snow is observed on south-facing slopes while snow, possibly deep, remains in shaded or north-facing areas. Under these circumstances, you should use good judgment to visually average and then measure snow depths in exposed areas within several hundred yards surrounding the weather station. For example, if half the exposed ground is bare and half is covered with six inches of snow, the snow depth should be entered as the average of the two readings, or three inches. When in your judgment, less than 50 percent of the exposed ground is covered by snow, even though the covered areas have a significant depth, the snow depth should be recorded as a trace (T). When no snow or ice is on the ground in exposed areas (snow may be present in surrounding forested or otherwise protected areas), record a "0". When strong winds have blown the snow, take several measurements where the snow was least affected by drifting and average them. If most exposed areas are either blown free of snow while others have drifts, again try to combine visual averaging with measurements to make your estimate. www.weather.gov/gsp/snowwww.ncdc.noaa.gov/monitoring-content/extremes/scec/reports/SCEC-Hail-Guide.pdf |

Chicopee is very similar to Rochester:
for 1991-2020.
May: 0.7
June: 3.9
July: 8.1
August: 6.5
Sept: 2.2
October: 0.3
Total: 21.7
Most was 54 in 2018, least was 5 in 2008.
Fort Collins has never recorded one.

This year's weather is truly turning out to be a piece of moudly old dung, based on model output for the next two weeks with massive Snorethern blocking, Greenland highs and cold wet wank for the UK. SIX DEGREES BELOW AVERAGE for the first week of Gay. Truly diabolical. What a blue waffle infested hole of a year 2021 is turning out to be. Fuck right off. I've almost completely lost all interest in the weather now. Fucking useless piss in this shit face Blighty Shitey "climate". FUCK IT.

Almost all of the 30-40mm of precipitation we've had this April has been frozen, despite the aversge having been 7.4/-2.2 with a 2.6'C mean, not counting today. The only time I've seen rain that I can remember was on the 13th when it rained for half of the day with the rest of the day being snow/sleet/graupel.  |

Over the last 30 years, April averages 176 sun hours and August 203 hours. Between 1991-2006, April was sunnier than August twice (1997, 2002). Between 2007-2020, April was sunnier than August 8 times, including 5 consecutive years between 2007-2011. April was also the sunniest month of the year on 3 occasions in the 91-20 period (2002, 2007, 2015), even though it is the 5th sunniest month on average.
The sunniest month of the year on average (July), hasn't actually been the sunniest month the most in the 1991-2020 period.
Apr: 3
May: 4
Jun: 8
Jul: 6
Aug: 9

Lol, why would anyone rational wish to have significantly below average temperatures at this time of the year in the Northeast?

Still seems unprofessional. NWS Melbourne also projects its warm bias in its tweets, using language like "hopefully" or "fortunately" when referring to warmer than average weather. If I wanted someone's weather opinions, I would come here. It's annoying seeing that in tweets and forecast discussions.
