This is a possible extreme event.
The average end of snow cover in far NW Canada is the first week of June.
Percentage wise 50% historical snow cover doesnt happen until around June 10th.
With snow cover lasting until June 20th a few years.
The average breakup dates for the Northern half of the MacKenzie river are May 25th to June 5th.
For the Delta plain the first week of June.
Ice free dates June 5th to 15th.
The part that really grabs attention is the modeled lows on day 6 on being in the low 50s over the DTA region.
Highs in the upper 60s to low 70s abd lows in the low 50s at the mouth of the arctic basin in the middle of May is huge.
This side of the Summer sun is normally going into snow and ice melt through May.
Not only within 3-4 days will the delta plain be near ice free there won't be any snow left.
Albedo goes from .55-.80 over snow covered land to .20 or so over green forests and grasslands.
Over the lakes, rivers, Delta and arctic ocean it drops to 0.08 roughly.
Solar insolation is about 410w/m2.
A week from now about 450w/m2.
We are talking about a potential regional extra uptake of insolation by the ground/water the next three to four weeks of 8000-10000 w/m2.
Of course it won't be that much.
But with ice and snow that drops to 1500-4000 w/m2.
And whatIs is absorbed goes to melting not warming the ground water and air.
Gonna be fun to track
