Really, really lovely cumulonimbus action tonight! I just happened to have my drone in the car and got some solid shots of DT Seattle/Lake Washington/Mercer Island/Bellevue looking north from Skyway. Alas, the focal length of the lens doesn't do the vertical height justice and my WB was off rendering it into semi-gross HDR territory, but still... fun looking weather! It was quite windy- I was flying right at 390 ft and the drone was giving me all sorts of warnings about sustained winds/gusts.
A most incredible snow storm. At times the snowfall rates have been as heavy or slightly heavier than January 2017. Temp 27.5, Dewpoint: 27.1 with gusty east wind and very heavy snow continuing. I'm at 11 1/2" now! UNBELIEVABLE!!!! This pic does no justice at all.
NBM is quite an interesting product! Their weighting algorithm is moderately complex and dynamic, though does has some drawbacks as we saw yesterday. For those who don't know, NBM is an attempt by NOAA to create a super probabilistic forecast model that ingests output from all the models above and outputs forecast guidance for local offices that help them to gauge the relative odds of particular weather outcomes. The 'special sauce' is the post-processing, normalization and weighting that they d
Some weather history for Southern Lower Michigan
1968: A tornado struck Big Rapids in Mecosta County, injuring 11 people and doing half a million dollars in damage as it covered a path 10 miles long.
1986: Freezing weather prevails across Lower Michigan. Record cold temperatures for the date include the 19 degrees at Muskegon and 20 degrees at Grand Rapids which is also a record for coldest so late in the season.
1985, the daytime temperature rose to 85 degrees in Flint, which is the record high temperature for the day. Curiously enough, the very next year, in 1986, the overnight temperature dropped to 22 degrees, setting the record low temperature for this day.
Across the USA
1948, A three block long section was devastated at the edge of Ionia, Iowa in Chickasaw County by an estimated F4 tornado. Six homes and a church were leveled, and nine other homes were severely damaged. Two deaths occurred in the collapse of the Huffman Implement Store. Overall, the tornado killed five people, injured 25, and caused $250,000 in damages. An F2 tornado touched down initially 5 miles northeast of Rochester. Barns, silos, windmills, and machinery were destroyed on four farms as this tornado tracked north.
1961, Severe weather struck the south suburbs of Chicago, IL. Joliet, IL reported an inch of hail with some hailstones the size of golf balls. Heavy rain from these storms also resulted in some flooding. A tornado struck the town of Peotone resulting in damage to nearly every building with damage also reported in Lorenzo and Wilton Center, IL. Estimated damage was $9 million with about 30,000 structures affected.
1989,
Salina Kansas was the hot spot in the nation with a high of 105 degrees. The high of 105 degrees established an April record for the state of Kansas.
The 30 year average is around 110, The all time record most was 145 in 2020 while the all time least was 48 in 1913. The number of days has really gone up since the 1970's
The official H/KL yesterday at Grand Rapids was 64/34 there was no rainfall the sun was out 74% of the time. It was yet another windy day with the highest wind gust of 41 MPH out of the SW. For today the average H/L is 61/40 the record high of 84 was in 1915 and 1925. The record low of 20 was in 1986. The most rain fall of 1.44” was in 1999. The most snowfall was 0.7” in 2005. Last year the H/L was 46/34.
The overnight low here in my MBY was 50 there was 0.03” of rainfall. At the current time it is cloudy and 55.
Yes, it sure does...the avg 100F+ degree days are between 100-110 days if I remember correctly. This will be my 1st official summer here in the PHX valley, however, I may be doing some traveling so maybe I won't spend as much time in the valley during the peak Heat season.
