Toronto4 Posted May 13, 2013 Share Posted May 13, 2013 There was a mixture of ice pellets/sleet/grapuel/wet flurries and rain showers yesterday in Toronto, even in the downtown core. The frozen precip was intense enough to result in Pearson Airport (YYZ) picking up 0.2" (0.4 cm) of snow yesterday. This is the first measurable May snowfall at YYZ since the 7th in 1989 where 0.3" (0.6 cm) fell. http://past.theweathernetwork.com/snow/snowON3 Link to comment Share on other sites More sharing options...
Hoosier Posted May 13, 2013 Share Posted May 13, 2013 31º at LAF, which bests the now old record for the date (32º in 2001). Radiating is one thing we do pretty well. Link to comment Share on other sites More sharing options...
Hoosier Posted May 13, 2013 Share Posted May 13, 2013 31º at LAF, which bests the now old record for the date (32º in 2001). Just to follow up, very few freezes have occurred at the airport after this date. The latest was May 21 so this was fairly impressive. Link to comment Share on other sites More sharing options...

Hoosier Posted May 13, 2013 Share Posted May 13, 2013 No doubt to both. Given the time of year and how the extended looks, have to think that was our last freeze and probably last chance for frost this season we get something fluky like June 1992.

michsnowfreak Posted May 13, 2013 Share Posted May 13, 2013 Very impressive cold this morning. DTW tied and therefore superceded the record low for today of 30F, so May 13, 2013 now ties May 13, 1971 for the coldest temp on record so late in the season for Detroit (from here on out no record lows lower than 31F, and even thats only on one day). Too bad no snow was reported at DTW yesterday. Ann Arbor ARB was the coldest spot in Michigan at 21F. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 13, 2013 Share Posted May 13, 2013 Ended up colder than yesterday morning at 34. Already back up to 63 though, and climbing fast. Only 67 in today's point, but we'll probably make the low 70s. 88 forecast for tomorrow. Link to comment Share on other sites More sharing options...
Chicago WX Posted May 13, 2013 Share Posted May 13, 2013 Full out blowtorch at LAF for the first nine days of May: 62.8º +4.4º How quickly things change. LAF now at 59.8º +1.0º through yesterday. Big negative departure today, and then we go back the other way starting tomorrow. Link to comment Share on other sites More sharing options...
Hoosier Posted May 13, 2013 Share Posted May 13, 2013 Tomorrow promises to be a huge swing in temps compared to this morning, so I was curious to see what kind of extreme day to day May swings there have been around here in the past. I searched Mays for the LAF airport back to 1964 (lots of missing data before that). There have been 6 occurrences of a 50+ degree change in temperature from one day to the next: May 4 1966 - low 30 May 5 1966 - high 82 May 4 1976 - low 31 May 5 1976 - high 82 May 12 1976 - low 32 May 13 1976 - high 86 May 14 1988 - low 40 May 15 1988 - high 90 May 16 1997 - low 34 May 17 1997 - high 84 May 14 2001 - low 41 May 15 2001 - high 91 As you can see, the last time that a freeze was immediately followed by a 50+ degree rise was May 12-13, 1976. With the low of 31 this morning, we would need to hit 81 tomorrow to have a 50 degree change. Link to comment Share on other sites More sharing options...

wisconsinwx Posted May 13, 2013 Author Share Posted May 13, 2013 Although it seems to be a low probability occurrence, the hi-res WRF NMM shows a short squall line developing in WC Wisconsin tomorrow night and then moving SE toward SE WI/NE IL. More likely any convective activity will be confined to C and N Wisconsin but we cannot discount this possibility I guess, especially if the warm front gets hung up further south.

cyclone77 Posted May 13, 2013 Share Posted May 13, 2013 90s already building into parts of Nebraska and South Dakota, and it's only noon out there. Heat is definitely building out west. Can see where the leading edge of the warmer temps aloft are, with that line of showers/storms in eastern Minnesota. Link to comment Share on other sites More sharing options...

Geos Posted May 13, 2013 Share Posted May 13, 2013 All the way down to 30° this morning. Luckily it wasn't below freezing hours on end - plants look unphased. One of the lastest hard frosts though. Day time underperformed though. Only 50 for a high. Link to comment Share on other sites More sharing options...
michsnowfreak Posted May 13, 2013 Share Posted May 13, 2013 Very impressive cold this morning. DTW tied and therefore superceded the record low for today of 30F, so May 13, 2013 now ties May 13, 1971 for the coldest temp on record so late in the season for Detroit (from here on out no record lows lower than 31F, and even thats only on one day). Too bad no snow was reported at DTW yesterday. Ann Arbor ARB was the coldest spot in Michigan at 21F. Heres the report from DTX RECORD EVENT REPORT NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 0915 AM EST MON MAY 13 2013 $ ...RECORD LOW TEMPERATURE SET AT DETROIT MI... A RECORD LOW TEMPERATURE OF 30 DEGREES WAS SET AT DETROIT MI TODAY. THIS TIES THE OLD RECORD SET IN 1971. I looked it up, and May 13, 1971 was actually a clear, seasonable day that got off to a cold start. DTW had a high of 70F (versus todays high of 56F). Still....as has been noted many times, in the 1960s-1970s DTW was an absolute magnet, if not epicenter, for radiational cooling. On those good radiating nights you usually couldnt find a temp lower in SE MI than DTW airport itself. With UHI those days are LONG gone and its almost the complete opposite, usually "the low was a chilly XX at DTW but most outlying areas were colder". I decided to look up low temps for May 13, 1971 and compare them to May 13, 2013 at stations that have long sets of data. I think this speaks for itself...2013 was the more impressive cold morning. There have been more impressive feats in the spring at later dates (May 22, 1883 snowstorm of 5" or rain mixed with snow on May 31, 1910..but neither of those snows even saw a freezing temp) but this has to be one of the latest widespread hard freezes the area has seen. Place........5-13-71 low....5-13-13 low DTW...................30............30 DET city..............39............32 FNT.....................31............29 LAN....................33............28 UofM Ann Arbor...36............28 Monroe...............38............27 Port Huron..........34............30 Ypsilanti..............34............30 Adrian.................32............28 Dearborn............35............31 Mt Clemens.........34............31 Car windshield at 845am today Link to comment Share on other sites More sharing options...
