WRF/NAM Snow Forecast! Yikes!May 14th, 2014 at 11:44 am by Bill Steffen under Bill's Blog, Weather
Check the WRF/NAM snow forecast – a little for NW Lower – significant snow for the higher elevations of the U.P. – probably way overdone, but still! Earl Barker’s NAM shows maybe an inch in the higher elevations – looks better to me. GFS has trace amounts in the U.P., with an inch west of Marquette around Herman. Marquette National Weather Service says: “…POSSIBLE WINTRY PRECIPITATION THURSDAY INTO FRIDAY…POTENTIAL FOR VERY LATE SEASON ACCUMULATING SNOW WHICH IS LOOKING A BIT MORE LIKELY FOR SOME AREAS…PTYPE FOR THIS INITIAL WAVE OF PRECIP LIKELY WOULD BE MOSTLY A MIX OF RAIN/SNOW…THOUGH HIGHER TERRAIN AREAS OF NCNTRL UPR MICHIGAN COULD SEE JUST SNOW BY LATER AFTN. Here’s the history of mid-late day snowfall in the U.P.
The image in the middle shows the mid-May ice cover on Lake Superior now down to 12.9%, which you can see on the MODIS Satellite picture on the right (from NOAA Coastwatch). Note the lack of clouds over the cold lake. You can also still see some snow on the ground in the Keewenaw Peninsula and north of Sault Ste. Marie.
This winter isn’t over until the fat snowman sings.
