Thank You National Weather Service, A Step in the Right Direction

By -

I learned from the National Weather Service yesterday that the NWS is going to drop from the April 1 experiment the modification of severe thunderstorm warnings to allow tornadoes to be included. 


The modification would have allowed the sentence, "A tornado is possible." in severe thunderstorm warnings. This is a step in the right direction and I congratulate and thank the NWS for making this change.


The plan to do three-tiered tornado warnings is still on for the April 1 start for counties served by their offices in St. Louis, Kansas City, Springfield (MO), Topeka, and Wichita. There is also going to be three-tier severe thunderstorm warnings. I have no objection to those because the science behind them is reasonably well established.

    Mike,

    I wondered why NWS was going to use the phrase "A tornado is possible" when the phrase "Severe thunderstorms can and often do produce tornadoes with little or no warning" has been around for some time now (and I believe was recently modified with this [paraphrased]: "While a tornado is not imminent, be prepared for rapidly changing conditions"). I'm still not on board with the multi-level tornado warnings but in a way, I do think that this is something they can forecast better in the future (e.g. the lower level warning would be, at best, 'get somewhere safe and inside' where as the high level would be 'be underground to survive this') although I know the focus is always 'take shelter' regardless of the severeity of the tornado.

    Is there a posting by NWS that talks about the criteria for three tier level warnings for severe thunderstorm warnings yet?

    Thanks for your time and I enjoy your blog.

    Pete

    Pete, as far as I can tell there is no press release on the experiment. I don't know why the NWS is being semi-secret about it.

    The "Wichita Eagle" will have a detailed article this Sunday.

Hilary's Forecast Path Shifts West; Updated 9:20am PDT

The forecast path of the center of Hilary has shifted a bit to the west. This increases the threat to the Southland, especially in terms of flooding.  Rainfall Note the heavy rains are forecast for Los Angeles County. Serious flash flooding may result. Because the forecast path has shifted to the west, that increases the threat of serious flooding in Los Angeles County north into Yosemite and the southern Sierra. It lessens the threat in Utah and western Arizona. While the threat of widespread flooding in Utah and Arizona lessens, note that some thunderstorms with localized heavy rain show up on the map.  In Nevada, the more western path increases the risk of serious flooding around Mt Charleston and into the central part of the state.  Here is the updated  (9am PDT) flash flood risk map. Wind There are already about 40,000 people without power in California, mostly in the center of the state.  The maps above are the peak gusts forecasted with the storm. The highest winds, in general,

There was at least one tornado and at least one funnel cloud yesterday.  --- original forecast --- Hilary (the swirly symbol) continues to move NNW paralleling the coast of Baja California, Mexico. The area outlined in red has a significant risk of tornadoe s the rest of the afternoon.  Below is a list of peak wind gusts so far.  Peak winds may increase farther north as the afternoon progresses.  Addition at 12 noon PDT: Sure enough, winds have increased.  Note: If you are in the San Diego area, I recommend not  traveling east on I-8.
