Welcome, Storm 60! Also, Spring.

Storm 60 is a SIGNIFICANT storm, a cold front that comes to us this equinox to ring in the northern hemisphere springtime.  SUNDAY morning satellite picture from GOES-West. Storm-60.jpg

Yesterday, it was very sunny! Today? Clouds, rain and snow are hanging about in select locations, for not all that long. An hour? Two hours maybe?  It’s not plan-altering weather even if you wind up in it.

Storm size is based on total precipitation received over a storm’s duration in 65 sampler cities and localities.
00.00 – 04.99 inches = “WEAK”
05.00 – 24.99 inches = “MINOR”
25.00 – 44.99 inches = “SIGNIFICANT”
45.00 – 64.99 inches = “STRONG”
65.00+ = “MAJOR”

Storm 60 dropped 29.70 inches of water on the 65 sampler cities, an average of .46 of an inch per city, making it the 15th significant system of the water year. Not bad for a storm that came in during a weak phase of the eastern Pacific jet stream.

The Jet Stream that powered this storm was arguably weak, merely the upper part of a jet stream split in two, with half the upper air wind speeds of a strong jet. And, sure enough, precipitation from this system was scattered and of short duration. But it also didn’t exactly do that bad.

That’s it for Storm 60. See you at the next storm.

Extended Outlook into April 2016

In speaking of strong jets, the weather chart, particularly the one featured below, suggests that in the later half of April, right after Tax Day, California could get one last series of strong storm systems delivered by a strong jet stream. El Niño, even though it is fading quickly, ought to have the jet stream cruising at California latitude, and the Madden-Julien Oscillation should have it flowing to California’s longitude! That would mean a lot of rain very late in the rainy season. Madden-Julien-Oscillation-Forecast.jpg
Think it’ll happen? THIS PODCAST can explain this chart somewhat better… it’s where I got this information.
