This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Willimantic and the stations that contribute to our estimates of its temperature history and climate. Groton-New London Airport (KGON, 2.5%, 28 mi, south, -210 ft elevation change).Chester Airport (KSNC, 2.6%, 27 mi, southwest, 197 ft elevation change).Hartford-Brainard Airport (KHFD, 3.3%, 23 mi, west, -203 ft elevation change).Windham Airport (KIJD, 92%, 2.5 mi, northeast, 26 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Willimantic is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Willimantic and a given station. There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Willimantic.įor each station, the records are corrected for the elevation difference between that station and Willimantic according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. This one fits that ilk.This report illustrates the typical weather in Willimantic, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. the upper bounders like impose "wild card" severity. Just like no one guessed a tropospheric fold would strafe SE zones in 2005, or how 128/95 becomes a stranded parking lot on the even of 1978 Feb 6. It's too possible that a dangerous scenario unfolds to worry about that, as the players are not in question - unlike other events this year. and is more a reflection of wobbling with the internal physics ( giga noise). It's roughly half way between the 12z and the oddly barren 00z run. I don't buy the 18z NAM and other waffling as negation. But, if the visibility is very low and the wind manages to gust in the interior and the temperature is 30 F. Snow, alone, is not the same beast to civility it was 40 years ago. I've seen this town cut through 22" snow storm twice and I was able to hit the gym later the same afternoon. Otherwise, I'm not too concerned about the risk for heavy snow as singular metric. I'm particularly concerned along a Willimantic CT to Bebford MA where for a time, thick caking/rhyme snow may then freeze while being struck with high winds into that snow loaded infrastructure. the upper bounders like to impose "wild card" severity. Just like no one guessed a tropospheric fold would strafe SE zones with sustained 'cane winds in 2005, or how 128/95 becomes a stranded parking lot on the eve of 1978 Feb 6. Hopefully the nit picking keeps it upper pedestrian/lower major like that. and ( I feel ) quite a bit of human interpretation, are not getting the big picture here of what this kind of event is capable of becoming. These subsuming N/stream fusion into diabatic inject S/streamers, become dynamic hammers ( in the maudlin turn of phrase). Too much tech dive is obfuscating common sense - not just in here but in the general Met community. The overwhelmingly powerful moving synoptic parts will obliterate the BL warming.
