Monster Gulf Coast Tornado Outbreak:
NWS in Jackson Mississippi reports today that the same giant parent supercell spawned one incredible long track tornado. The giant EF4 monster packed 170 mph winds and was 1.75 miles wide at the base, with a path length of 97 miles! The tornado killed 10 people in Mississippi alone.
Check out the latest updated NOAA SPC storm reports from Saturday's devastating southern tornado outbreak. At last count, 69 tornadoes were reported. Keep in mind that about one third of these are likely multiple reports of the same tornado. Still the numbers are staggering.
Notice the nearly linear path of the red tornado triangles from northeast Louisiana through Mississippi and Alabama.
Saturday's outbreak makes April by far the most active tornado month so far in 2010 with 89 tornadoes reported so far. It had been a record quiet tornado year so far, with only 78 tornadoes reported during the first 3 months of 2010.
Enjoy our return to quiet weather and sunshine this week. Our next chance of thunderstorms rolls in late Thursday.
Our amazing spring of 2010 continues. Last Friday I was stunned to see a row of common purple lilacs blooming in Deephaven. That's April 23rd!
According to long time Twin Cities phenologist Jim Gilbert's Nature Notes; this would put 2010 as one of the earliest lilac bloom years on record. The average date for the lilacs to open in the Twin Cities is around May 10th, with peak bloom the following week.
Jim's records from the Minnesota Landscape Arboretum in Chanhassen show the early Flowering Crabapple peak bloom we're seeing now rivals the years of 1987 and 1997 when the trees also reached peak bloom in late April. Jim has observed the lilac bloom average dates have moved a full two weeks earlier in the past 40 years.
The triggers for our early spring blooms are the 4th warmest March and 2nd warmest April on record so far. This is pretty remarkable stuff when you consider that last year's lilac blooms occurred in May close to the average date.

As 40,000 gallons a day leak from the collapsed oil rig in the Gulf of Mexico, the signs of the event are now visible from space. The photo above shows the spill southeast of the Mississippi Delta at 1km resolution. You can see the higher resolution images here.
So far the oil appears to be out at sea, but if the leak continues and ocean currents send the slick toward the Gulf Coast we could have the makings of coastal ecological disaster just days away.
