Seems a little hard to believe but dewpoints were in the upper 70s/low 80s before that and it appears there was a front moving in based on the obs, which could've resulted in some moisture pooling. It's really hard to get an ob like that unless the sensor is in the middle of a corn field or it just started raining. Link to comment Share on other sites More sharing options...

stormtrackertf Posted November 13, 2012 Share Posted November 13, 2012 One of my personal favorites of all time from DTW, simply because it came out as "Heavy Thunderstorm Rain Fog Squalls and Windy" on the DTX observation page. This was May 23rd, 2004 at 6:54PM EDT: METAR KDTW 232254Z 23026G68KT 1/2SM +TSRA FG SQ FEW005 BKN027 OVC044CB 19/18 A2970 RMK AO2 PK WND 22068/2247 TWR VIS 4 TSB00RAB09 SLP054 CON LTGICCG S-SW AND OHD TS SW-W AND OHD MOV E P0095 T01890183 RVRNO The rain was absolutely torrential as well. I actually remember a seperate severe event when a Derecho hit the area on the 21st, and it produced rainfall rates in excess of 6" an hour. Luckily, the storm moved at such a violent forward speed it only dropped about an inch of rain or so, but it's no surprise that this was the wettest May ever in Detroit with all of the severe weather events that occured that month.

That 85 airmass was the real deal. Those record/really low temps weren't achieved with anything close to optimal radiational cooling. It was super cold air advection at work. There was a pocket of -30C air over LAF around the time of that observation. Combine that with snow cover at the coldest time of the year and crazy things can happen. Another good ob from that event... -13F with light snow on the evening of the 19th...probably one of the coldest temps with snow at LAF.
