Where the heck is the 3-5 inches of snow we were promised last night? The NWS never acknowl­edges errors in their fore­cast prod­ucts, but for­tu­nately you can also read the tech­ni­cal dis­cus­sion:

    BASED UPON RADAR TRENDS AND LATEST MODEL GUIDANCE WE ARE BACKING OFF
    ON ACCUMULATIONS FROM PREVIOUS FORECAST...AND WILL DROP ADVISORIES 
    FOR I-95 CORRIDOR AND LOWER WARNINGS TO ADVISORIES FOR S COASTAL 
    ZONES.

    IF WE WERE ALL AT 10KFT THIS WOULD BE A GOOD SNOWSTORM...BUT LOW 
    LEVEL DRY AIR HAS BEEN WINNING THE BATTLE ALL NIGHT AND WILL LIMIT 
    NORTHWARD EXTENT OF SNOW SHIELD THIS MORNING. SURFACE MESOANALYSIS 
    SHOWS RIDGING WORKING DOWN INTO NORTHERN CT...NW RI AND MUCH OF SE MA
    WHICH CAN ALSO BE SEEN BY A LACK OF ECHOES ON KBOX 88D.
