12z European computer model (ECMWF) 4-4-19
Looking like will see quite a temperature contrast setting up on Saturday, and probably on Sunday as well with temperatures Saturday afternoon ranging from the 30s near Lake Superior to the 60s across southern Minnesota, possibly even near 70 degrees along the Minnesota-Iowa border!
18z NAM-WRF model 4-4-19
Radar forecast valid 7 AM Saturday to 1 AM Sunday
Periods of rain are expected this weekend in northeast Minnesota and northwest Wisconsin with a few thunderstorms as well. The risk for thunderstorms is greatest from Saturday afternoon into early Sunday morning, this is when the elevated CAPE will be greatest per model guidance (100-400 J/kg)
Much of the Northland can expect between a half to three quarters inch of precipitation this weekend with locally higher amounts possible.
21z RAP model 4-4-19
Still looking at a chance for a little snow or rain across the Northland tonight, but this doesn’t look like a big deal. Snowfall accumulations ranging from a dusting to an inch with the greatest chance for an inch of snow over the tip of the Arrowhead (Grand Marais, Hovland areas) Precip totals of a trace to around 0.05 inches are possible in parts of the area by 7 AM Friday.
Might not be done with the snow quite yet!
I’ll be monitoring model trends closely in coming days to see if they continue to show a storm for the middle of next week, and if they do, what track will it take? Lots of possibilities out there right now which isn’t surprising for a storm that is several days away.
Note: Black lines on map indicate possible storm tracks for April 10-12.
It can snow around here in April, I know that may be shocking to some of you, but it’s really not that unusual! Duluth averages nearly 7 inches of snow in April, and just last April on the 15th, Duluth picked up a foot of snow!
