  1. We picked up quite a bit from the storms last night here in northern indiana. I'm in the process of acquiring a new stratus gauge so I didn't get any readings but other sources said 3 - 3.5" over the span of two hours. Really torrential rain. At one point I looked down to see it flooding into the warehouse around midnight.

    Good grief a better system on Thursday ? So they must be thinking at least 10" for Thurs ?

    GFS v16 shows us cashing in on 12 inches with this first system and then ramps the total up to 18 by 00z Sat. So roughly 6 inches for the Thursday deal but still a long way out. It almost seems to follow the same track, snow amounts increase pretty linearly compared to the Monday system.

  3. Area Forecast Discussion
    National Weather Service Northern Indiana
    535 AM EST Sun Feb 14 2021
    Confidence is medium in the forecast overall, with
    greater confidence in the southeast and lower confidence along the
    northwestern fringes. The totals occur over a 36 hour period, so we
    fall short of warning criteria in our far southeastern CWA. In
    collaboration with neighbors, opted to keep a high-end advisory for
    now, with potential for upgrade to a warning if the more aggressive
    solutions (NAM/ECMWF) look more likely.
    The first system will lift in
    tonight and exit by Monday afternoon/early evening before the next
    system if the GFS/GEM are correct. However, the ECMWF and especially
    the NAM keep the precipitation ongoing through that period, and
    develop a coupled jet structure right around 00z--which really amps
    things up as far as forcing goes. In addition, the ECMWF/NAM also
    have a weaker surface high sprawled across the midwest (as opposed
    to the GEM/GFS solution), which allows for that secondary low to
    lift further northwest as the stronger mid level trough inches
    eastward into Monday night/Tuesday.
    
    As far as Thursday`s system goes, both the ECMWF/GFS bring the upper
    level trough into the upper Great Lakes, and the subsequent strong
    surface low northeastward from the gulf into the lower Great
    Lakes/Ohio (the GFS faster and deeper with the system). With a
    negatively tilted trough and deepening surface low, I tend to go
    with the stronger solution and further northwest track. So have
    likely pops in the eastern CWA (mainly along/east of I 69) late
    Wednesday night into Thursday evening, and high end chances for the
    central CWA (lowest west half). Think this could be a better system
    than these first two, but a lot could change by then with this
    active short/mid term forecast so will hold off on any further
    discussion.

     

    So IWX may go to a warning, who knows. Forecasting 3-5 inches for us right now. Also a possible second "better" system on Thursday!

  4. We were dealing with a moderate drought here in northeast Indiana and the lake levels are very low. Somewhere along the line we were upgraded to Abnormal but we still have a lot of storage to fill along the watersheds. With this prolonged cold the snow is piling up though and I feel like by the end of next week even more will have accumulated.

  5. I think these models are over doing the long term and the only thing I base that on is the fact that temperatures warmed almost 12-15 degrees for this early week cold spell. Euro next weekend is showing below zero for my area and I feel like it will be a tad warmer when it gets here.

    GFS needs to do a reboot or spyware check.. something.. geeze.

  6. 12z Euro @240 is showing some really abnormal cold still hanging around for Saturday morning. I really don't see that happening. The short term has regressed back to the plains for the most part. Monday morning in my area was forecast to be -12F, now its up to 14F.
