First the front. Here is a visible satellite picture around 12:30 PM PST. You can see the clouds associated with the front to the south and southwest of the Big Island, with cooler, unstable air to the Northwest.
But the behind the front something happened to the east of the Big Island that should warm the heart of any Northwesteners-- a convergence zone formed... a kissing cousin to our own Puget Sound convergence zone.
Did you ever consider that the Olympic Peninsula and the Big Island are both mountainous and similar in size? Roughly 60 miles in diameter? Here is the proof:
Today, as winds turned northwesterly over the Big Island, a nice convergence zone formed in the lee (southeast) of that barrier. Here it is:
My colleagues at the University of Hawaii run the MM5 high-resolution model over the Aloha State. Here is the simulation of the 10-m winds valid 5 AM Hawaii Standard Time. You can see the general northwesterly winds and the convergence in the lee of the Big Island. The other islands don't peturb the flow much; the Big Island is not only large, but has two very large mountains--as high as Mt. Rainier.
Northwest Weather Workshop. This is major local meeting for weather professionals and enthusiasts. All are welcome. March 2-3 in Seattle. Info here on the meeting and registration. The banquet speaker on Friday night will be Andy Wappler of Puget Sound Energy.
Latest on my lost dog: There have been several sightings in Brier, to the east of Mountlake Terrace. If you live or work there, keep an eye out! The bureaucrats working for the city of Mountlake Terrace are tearing down our signs, even those on private property away from the street--really crippling our effort to get her back.
