Yesterday was a summer like day with the official H/L at Grand Rapids of 83/49. There was no rainfall and the sun was out 90% of the possible time. The average wind speed was 4.1 MPH. For today the average H/L is 71/50 the record high of 91 was set in 1977 and the record low of 30 was set in 2002. The most rainfall of 2.88” fell in 1938. Last year the H/L was 68/50 and there was 0.02” of rain.
The overnight low here in MBY was summer like 63 and the current temperature is 68 with clear skies
KSEA will challenge 1996 for the record min/max this Tuesday. Mark is 52F. Not sure if we'll beat it but we could match.... The margins are razor thin.
Mesoscale models picked up on this shower activity. The bulk of the cold air is now passing overhead and there are some converging airstreams in the lee of both the Olympics and Vancouver Island under stout NW flow as our ULL exits the westside. That and the Snohomish plateau is initiating a lot of this.
Looking at radar, the north end of the city is getting some leftovers. Most of it is dissipating before it quite reaches here, but I suspect that could change at any point.
