Tuesday Rain

September 26th, 2011 at 2:36 am by under Bill's Blog, Weather

Local Tuesday 10:40 PM -  The upper level low is over Berrien Co. – drifting painfully slowly to the ENE.  Showers continue to rotate around the low and that will continue into Wednesday.    Thursday, we may get a period of dry weather in the morning, but a band of rain should arrive in the PM along the next cool front.  It’s gets windy and chilly on Friday with showers and a stiff NNW wind.  Then things slowly improve for next Sat. afternoon and Sunday.   Here’s radar and links: current Grand Rapids NWS radar, Regional Radar, GRR Zone Forecasts, lightning for our area and national lightning data. Here’s the latest visible satellite loop, current U.S. severe t-storm and tornado watches, current meso-discussions, and today’s storm reports from SPC. Here’s Storm total rainfall, Milwaukee radar, Chicago radar, current Michigan conditions, and the National warning/watch/advisory map. You can checkout the latest Grand Rapids NWS discussion, the Northern Indiana NWS discussion (includes the Michigan Counties that border Indiana), the discussion for Northern Lower Michigan, and Eastern Lower Michigan. Here’s a surface weather map, infrared satellite loop (day or nighttime). To report hail, strong winds or other severe weather to Storm Team 8, call 1-800-8WOODTV.

      That is really cool. That low just doesn’t want to go anywhere…

  3. Northern Lights possibly visible tonight. A Severe geomagnetic storm (Severe Aurora) is in progress right now. If we can keep the clouds away a little while longer, and if the storm doesn’t subside too quickly, we have another chance tonight.

    was just checking the radar..whats up with that big swirl of rain around michigan? is what’s in Ill. now going to get to us tonight?

  5. SS (Pwell Area) says:

    Do you think it will be a washout today?!?!

    1. Irish coffee says:

      washout? no….several DRY hours interspersed,fwiw

  6. WHat! says:

    How is this Huge low different than a hurricane?

    Why are the bands of rain in a extended swirl instead of a tight one?

    1. Cort S. (Plymouth, NH) says:

      This is a cold-core low which got cut off from the mid-latitude westerly steering winds (jet stream). A hurricane is a warm-core system fueled by warm ocean temperatures.

  7. Travis (Oxford, MI) says:

    Looks like the eye of the low is right around West Mich. I hope it doesn’t move east. We had a gorgeous, partly cloudy night last night, and it’s been 90% blue skies here today!

    1. Travis (Oxford, MI) says:

      It almost seems like the low is stalled but moving slightly west, if anything? Where do you envision it going, Bill? I hope it doesn’t sit on top of us after you guys in West Mich.

      1. Cort S. (Plymouth, NH) says:

        An upper-level trough came down through Canada/Minnesota/Wisconsin long about last Wednesday, then got cut off from the jet stream which otherwise would have kept it moving along. It closed up into a full upper-level circulation and has since been sitting and spinning over roughly the same spot in/around northern Illinois. Upper-level cut-off lows do tend to retrogress slowly towards the west, and it did that slightly this weekend. Low pressure at the surface was induced by the cut-off upper-level low this weekend (see the animation of the surface low here). It’s starting to move very slowly toward the east, and is now centered just southeast of Gary. In the coming days it’s going to be kicked out of here by an approaching upper-level trough that’ll swing through the Dakotas, Minnesota, and Michigan. As of right now that trough is expected to slowly move east out of the country by the end of the weekend. In its place, high pressure will build in and temperatures will start to warm up early next week.

          This is awesome… this will illustrate what’s been happening in the upper levels ever since Thursday.

          That’s an upper-level water vapor image. Yellow is dry air and means likely partly sunny or sunny conditions. The blues and whites are moist air which would mean clouds and sometimes precipitation.

    70% chance of rain everyday until Thursday for me here!

    could have used this like a month ago. Good job on the posts Cort, you always share great stuff. Thank You.
