A major atmospheric pattern change is underway, and the Pacific storm door is open. A major winter storm supported by an atmospheric river of high moisture is pounding Oregon, California, and Washington today, bringing record flooding, heavy snows, freezing rain, and damaging winds. The ridge of high pressure that had brought much of Northern California its driest winter period on record during the past two months has retreated to the northwest towards Alaska, allowing the subtropical jet stream to dive underneath the ridge. The subtropical jet is bringing a plume of moisture called an "atmospheric river" to the coast between Northern California and Southwestern Washington, resulting in heavy rains near the coast and snow measured in feet to the mountains. Heavy rains of 2 - 5 inches have affected much of Western Oregon over the past 24 hours, and the Marys River in Philomath has risen to its highest flood on record. Additional rains of 1 - 3 inches are expected today over the region, and damaging major flooding is expected along several Oregon rivers.


Figure 1. Radar-estimated precipitation for Oregon shows a wide swath of greater than 8 inches of rain has fallen since January 16 over Western Oregon.

Heavy snow, ice storm hit Seattle
Yesterday in Seattle, Washington, 6.8" of snow fell, making it their greatest 24-hour snowfall since November 1985. Winds gusting to 85 mph in the mountains to the east of Seattle closed some ski areas, but heavy snows of 38" in 36 hours fell at White Pass, and the this weekend will see the best skiing of winter in Washington. The problem will be getting to the ski areas--an ice storm this morning has closed the Sea-Tac airport and snarled traffic.

Record dry spell ends for California and Nevada
Skiiers, take heart: Tahoe's Ski Season From Hell will end this weekend. A series of three snowstorms will pound the Sierra Mountains of California and Nevada, bringing the first heavy snows since November. According to Tahoe weather historian Mark McLaughlin, December 2011 was the second driest in the Sierra Mountains since record keeping began in 1920. He based this on an aggregate of data from eight locations from Highway 50 in the south to Mt. Shasta in the north in the central and northern Sierra Nevada. This winter has seen the longest winter dry spell in history in Reno, Nevada (56 days). The dry spell ended on January 16, when .03" of precipitation fell. The previous longest dry spell was 54 days, ending on January 24, 1961. Farther to the south in Minden, Nevada, the record dry spell ended at 72 days on January 16. Nevada's Carson River Basin snowpack is at 8% of normal, compared to 224% last year at this time. In San Francisco, the first significant rains since November 20 are expected to begin later today. The past two months have seen just 0.26" of rain in the city, making it the longest two-month winter dry period in the city since records began in 1850, according to wunderground's weather historian, Christopher C. Burt. Fresno, Califonia has seen no rain at all since November 20, and that dry spell should end today or Friday. Today's storm in Northern California will be followed by a new storm on Friday, which will bring 100 mph wind gusts and 1 - 2 feet of snow to the Sierras (2 - 3 inches of rain equivalent). A third storm with more snow is expected on Sunday night.


Figure 3. Satellite estimated water vapor in the atmospheric expressed as how much rain would fall if the entire amount of vapor were condensed in a vertical column. Where this "Total Precipitable Water" exceeds about 25.4 mm (1 inch), heavy precipitation can occur. An "Atmospheric River" extending from Hawaii with very moist air harboring precipitable water values near 1.5 inches (38 mm, light blue colors) is impacting the coast near the California/Oregon border, bringing heavy rains and snows.

Mission Status Center
By Justin Ray

Welcome to Spaceflight Now's live coverage of the Delta 4 rocket launching the WGS 4 military communications satellite. Text updates will appear automatically; there is no need to reload the page. Follow us on Twitter.




0005 GMT (7:05 p.m. EST Thurs.)
The ULA launch team and the mission management group are guiding the countdown from the Delta Operations Center, located about 9,200 feet from the pad. The engineers overseeing the rocket and ground systems are located on the third floor and the Mission Directors Center room is on the fourth floor. Both rooms have a view of pad 37B and the Delta 4 rocket out their windows. Other rooms are also set up for engineering support.

The DOC was formerly built to support the Titan-Centaur program but was refurbished to support Delta 4.

Lot's of interesting articles on that website, Nea. Thanks for posting the link.

I'll flog AGW with this one.

"Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day%u2019s temperature.

"In three separate studies, researchers affiliated with Columbia University%u2019s Center for Research on Environmental Decisions (CRED) surveyed about 1,200 people in the United States and Australia, and found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. A new paper describing the studies appears in the current issue of the journal Psychological Science."

The moral seems to be: All climate is local weather.

Which is reminiscent of Tip O'Neil's observation: All politics is local.

My own position is that global warming is just a political problem now. The science is stout.
That's interesting, all right. It reminds me of a similar study--and I'll link to it if I can find it--that said people who live in warmer climates (tropical, desert) are more liekly to agree that the planet is warming than those who live in more temperate or polar regions.

Anyway, I would agree with your position.

True. It wouldnt really make sense to retire one but not the other. Except, maybe it's just because i live in the northeast, but i feel like overall Lee got more press coverage than Dolly. did it seem like that in other places?
They really didn't give Dolly as much coverage at first because they though it was going to be just another T.S.But it manage to intensify to a cat 2,and at that moment it started getting coverage.

    =======================================

    At 18:00 PM UTC, Severe Tropical Storm Ethel (990 hPa) located at 17.4S 65.8E has 10 minute sustained winds of 50 knots with gusts of 70 knots. The cyclone is reported as moving south southwest at 13 knots.

    Dvorak Intensity: T3.5/3.5/D1.5/24 HRS

    Storm Force Winds
    ================
    20 NM radius from the center

    Gale Force Winds
    =================
    60 NM radius from the center

    Near Gale Force Winds
    ======================
    70 NM radius from the center extending up to 90 NM in the southern semi-circle

    Forecast and Intensity
    =======================

    12 HRS: 18.3S 64.7E - 60 knots (Forte Tempête Tropicale)
    24 HRS: 19.3S 64.1E - 65 knots (Cyclone Tropical)
    48 HRS: 22.6S 62.6E - 60 knots (Forte Tempête Tropicale)
    72 HRS: 25.8S 62.5E - 40 knots (Tempête Tropicale Modérée)

    Additional Information
    ======================

    1618 PM UTC F18 microwave imagery confirms the improving of satellite feature. Ethel keeps on intensifying.

    Most available numerical weather prediction models remain in good agreement to forecast a southwestwards to south-southwestwards track over the next 2 days then a southwards recurving motion. On this track the system should move over or near Rodrigues island Friday late or Saturday early.

    Within the next 36 to 48 hours, environment remains rather favorable for further development. In the upper levels, system takes currently always benefit from a good outflow channel poleward which is expected to improve day after day. The system should close to it speak intensity as it passed near Rodrigues.

    Vertical northwesterly wind shear, cooler sea surface temperature and interaction with the westerlies is forecast to weaken the system and make it loose tropical characteristics at the end of the period.

    The next tropical cyclone advisory from Mauritius Meteorological Services on TC ETHEL will be issued at 0:30 AM UTC..

    22:00 PM RET January 19 2012
    =======================================

    At 18:00 PM UTC, Moderate Tropical Storm Funso (990 hPa) located at 18.2S 39.9E has 10 minute sustained winds of 45 knots with gusts of 65 knots. The cyclone is reported as moving west southwest at 8 knots.

    Dvorak Intensity: T3.5/3.5/D1.0/12 HRS

    Gale Force Winds
    =================
    40 NM radius from the center

    Near Gale Force Winds
    ====================

    24 HRS: 18.9S 37.6E - 70 knots (Cyclone Tropical)
    48 HRS: 18.4S 37.3E - 70 knots (Cyclone Tropical)
    72 HRS: 18.7S 39.0E - 80 knots (Cyclone Tropical)

    Additional Information
    ======================

    Cloud pattern has consistently improved along the day with very deep convection flaring and wrapping around the center. Europeans numerical weather prediction models (ECMWF, UKMO, ARPEGE) are in good agreement for a globally southwestwards forecast track up to 36-48 hours. On the northern edge of a subtropical ridge and then a eastwards to southeastwards track with a steering flow directed by the equatorial ridge to the northeast before a new westwards turn at the end of the forecast period under th e steering influence of a subtropical ridge that should build south of the channel.

    Over this track, environmental conditions are very favorable for regular further development with a good low level inflow on the both sides, weak vertical wind shear, well sustained by two upper level outflow channels, heat potential is strong over 29-30C sea surface temperature. The intensification process is held off between 36-72 hours as the system should move little near the Mozambican coasts. This slow motion over the same waters could be an inhibiting factors.

    Within the next 48 hours, the system should get closer of the Mozambican coasts near the Quelimane region with a potential direct impact that could not be ruled out at this time ...Inhabitants of this sector should closely monitor the progress of this potentially dangerous system.

    The next tropical cyclone advisory from Seychelles Meteorological Service on TC FUNSO will be issued at 1:00 AM UTC..

    Checking out that article Nea. This conclusion is not surprising.

    "... they identified two parameters that seemed closely associated with monthly tornado activity: rain associated with strong updrafts; and helicity, which measures the tendency of winds to spin those updrafts."

    The following observation might have to do with tropical cyclones.

    "The index correlated significantly with the observed numbers of tornadoes in all months except September and October."

    This bit does sound interesting, though.

    "Moreover, the National Oceanic and Atmospheric Administration (NOAA) system for making seasonal forecasts, known as the Climate Forecast System (CFS), was able to use the index to forecast monthly tornado activity with some success up to a month in advance. This success, especially notable in June, is the first evidence for the predictability of monthly tornado activity.

    "Harold Brooks, a NOAA tornado expert not involved in the study said the forecast technique worked where others have failed because the CFS produced higher resolution results. “The real breakthrough is that CFS is skillful enough at the right scale,” he said"

    The real story seems to be the CFS.

    Both systems are continuing to show signs of organization. However, Funso is expected to strengthen very gradually, if not rapidly. Meteo France expects this to reach a strength of "Intense Tropical Cyclone". In 5 Days, Funso should continue to meander in the Mozambique Channel.

    As someone living western Oregon, I can testify that it really is as floody as Jeff says. And the rivers haven't even crested yet.

    The map below shows just how many of our local highways are flooded or closed for other reasons. In fact, all highways from the Willamette Valley to the central Oregon coast are now closed.

    I don't think I would give the GFS any credience to that right now as the models are having a hard time pinning a forecast 5 days in advance due to this lingering La-Nina. If any thing it's going to get even warmer. I wouldn't be surprised to start seeing 90's popping up in TX & FL over the next couple of weeks.
