Bruce’s Briefs: Wx for 26, 27, 28, and 29 Mar. CYC Three Tree Point Rac

Almost an inch of rain yesterday (at the airport) and as of today, we are 3.5” above normal and .75 inches ahead of last year which was abnormally moist. Just as long as we don’t get too much heat too fast, it’s fine. Plus the freezing level is going to be coming down significantly late Sunday and into Monday which will help preserve the snowpack. Don’t be surprised to see some snowflakes mixed with the rain.

Today’s surface analysis chart shows the remains of a weak low-pressure system right on top of the Pacific NW hence the cloud cover. There is also a respectable high offshore (1033Mb) which isn’t going to move very far and will help weaken the next front that is due to arrive late Sunday. When you compare the surface chart with the 500MB chart you’ll also see that this high extends well aloft. This is keeping the jet stream to the north before it dives to the south and comes ashore at the US/Mex Border and heads due east. This is the same formula that has resulted in the wild weather in the SE USA over the last 10 days.

Today’s satellite pic, while showing some clearing in the Straits of JdF, still has plenty of cloud cover over the rest of the area. This will continue through tomorrow, just don’t be fooled, be sure to put on plenty of sunblock before you leave the house.

While we have just about a perfect wind for the TTP Race today, the surface forecast chart shows that the pressure gradient will ease over the area tomorrow keeping the breeze in the 5-10-knot range for the start with less wind to the south and the breeze over the racecourse gradually easing over the day. Luckily for us, the Race Committee isn’t afraid to set an alternative course to take advantage of what wind is present. Might as well make it a clean sweep for the Center Sound Series.

Luckily for us, the tides won’t be an issue.

The current NAM model has the TP-52’s around the course in about 6.25 hours, the J-111’s around in 7 hours, and the J-35’s and J-109’s around in 8.5 hours.

By Sunday, another system will make its presence felt over the area as it brings rain and wind to the Salish Sea. It will have the effect of weakening the high currently off of our coast and moving it slightly to the south. What’s very interesting is the 1042MB high behind this front and the 974Mb low off to the NW of this high. Not a trivial low-pressure system. This will be fun to watch as we approach the end of the month.

Have a great weekend.
