(Picture is snow in the U.P Thurs. AM – from WLUC – click the pic. to enlarge). Second picture is rain/flooding in Las Vegas NV. Here’s snow reports from the central U.P. Four inches of snow fell at S. Ste Marie. October 1-11 has been 3 degrees cooler than average. Oct. 1-11 last year was 6.1 degrees warmer than average (so right now we’re running 9.1 degrees cooler than last October) with no rain. We’ve had at least a trace of rain on 9 of the last 10 days. The new 00Z NAM caribou model is very similar to the Thurs. morning run. It prints out 1.59″ of rain for the weekend. The 00Z GFS has 1.67″ with 0.84″ on Saturday and 0.83″ for Sat. night/Sunday. Actually, the GFS plot prints out a whopping 5.43″ for G.R. over the next 16 days…probably overdone, but certainly a wetter pattern than we have had. The NAM caribou has the strongest wind at a steady 26 mph early Sunday afternoon.
The storm that’s headed our way for the weekend produced heavy rain in the SW U.S. Needles, CA in the desert reported 1.59″ of rain! Bullhead City had 0.98″ and North Las Vegas NV. had 0.92″ (that’s more than 3 times the average rainfall for the entire month of October). Waterspouts were reported off San Diego. Hail piled up 2″ deep in Gilroy CA. Los Angeles had it’s first measurable rain since May 1st (and some local flooding) and San Diego had the first measurable rain since May 25th. It’s been the wettest Aug. 1 to Oct. 15 ever in Las Vegas.
Also a rare significant “once in a century” late season snowfall has hit parts of Australia. Two major roads were closed by the snow, which accumulated to 10 centimeters (about 4″).
