    Both nams have a lot of elevated instability tonight. Overnight bangers.

    That's some pretty impressive elevated instability by the NAM overnight. Even the latest HRRR is pretty solid. Think we want to watch for whether we can sneak into the northern edge of the steep lapse rate plume which should at least graze the coast. Regardless, still decent elevated instability but could be looking at something along the lines of 500-800 J versus upwards of 1500+ if we can get into those steeper lapse rates. 

    Perhaps some risk for large hail?

    It's pretty annoying when BOX and ENX are both range folding right over us when the strongest cell in the area is here.  As was the case this evening.

    Yeah that was frustrating the heck out of me. Had two phones in my hand because I was taking some video in the event the winds got real so wasn't able to easily switch tilts to try and sample a bit higher up.

    I wish we could get a TDWR at BDL

    Look at the ass hammerin' abuse the NAM afflicts Boston with on this 12z grid for Thur, compared to Albany and New York City... The highlight are the T1 temperature... actual SFC is typically 3 or so warmer than these.   Luckily for warm enthusiasts, the wind field at Logan on Thursday is only 8kts so it's not likely moving west of the city... but jeez!

    This is more for Wednesday but wild differences between guidance at BOS for tomorrow

    6z MAV: 65

    0z MET: 57 9z high then dropping

    7z NBM: 69

    I was actually expecting the 13z NBM to tame down at BOS but nope...came in at 71 :lol: . Been that seems wayyyy too high. Highest 3hr value anyways is 64 which still might be a bit high...though BOS might have a chance to climb before the E winds kick in

  4. Absolutely wild the differences in guidance in how convection develops/evolves tomorrow. the 3km NAM highlights exactly what I was thinking yesterday in terms of potential/evolution but it doesn't have much support. But then again, not one model has support from another. Ahh the fun of convective forecasting :thumbsup: 

  5. The 18z HRRR does have a line moving through late PM. Might be dependent on exactly how much heating there is. The overall forcing looks pretty weak but it does look like a weak boundary will be sliding through...could be enough to get things going. Looks better north though
