Tony Posted March 29, 2014 Report Share Posted March 29, 2014 It looks like the 1st wave(6z GFS) puts down snow or ice so back and forth the models go. 1 Quote Link to comment Share on other sites More sharing options...

Temps will be marginal with this system.It was the first week of April back in the early 80's and we had close to a foot of snow. My friends and I were just coming back from Florida and we had a heck of a time driving from Indiana to Chicago. So yes it can stick no matter what the temp is as it was probably in the 60's prior to that storm. 1 Quote Link to comment Share on other sites More sharing options...
bud2380 Posted March 29, 2014 Report Share Posted March 29, 2014 Well last year on may 1st many areas in Iowa saw heavy snow make roads slick. Some places reported 11" of snow. But it is true that it does have to snow hard during the day for it to do a lot of accumulations on the road this time of year. At night not as hard. Also hour 144 on the gem appears to show widespread snow in the Midwest Quote Link to comment Share on other sites More sharing options...

Haha, not that old to remember that one!Well the only noteworthy April snow (day) that I remember was 04/11/07 and I remember shoveling what fell up to about 9am. Once the driveway was clear it snowed another 6 hours, but it didn't accumulate on the driveway more than a minute or so. Temp was 32-34° for the whole event and I remember during light radar returns it would turn to rain. Another thing that is common with daytime April snow systems - it has to snow moderate to hard just to prevent snow flake melting before they reach ground level.

Temps will be marginal with this system. NE Ohio is getting hit good right now and the snow is accumulating on all surfaces right now.

Yes, but they haven't experienced temperatures like there will be tomorrow and Monday. Paved surface should be able to warm easily into the 70s and retain enough heat so salt doesn't have to be used. My neighbor who works for the township said that pavement temps are already well above freezing and doesn't expect to use anymore salt this season. That was his take and I figure that sounds legit.Roads during the day should be a non issue. 1 Quote Mercer Island, 350 ft 2021-2022: 11.6", 02/21 2020-2021: 15.6" 2019-2020: ~10" 2018-2019 winter snowfall total: 29.5" 2017-2018: 9.0", 2016-2017: 14.0" Link to comment Share on other sites More sharing options...

tim the weatherman Posted March 29, 2014 Report Share Posted March 29, 2014 was just looking at the mjo and shifting to phase 4 (within the next two weeks we will have a pattren shift so troughing in the west and ridging in the east).7-8-1 are the best for ridging on/near the West Coast, which allows troughs to amplify in the in the Eastern half. 3-4-5-6 are the torchy phases, as they tend to produce troughing in the west and ridging in the east.
