March DISCO/OBS: Please End It


40/70 Benchmark
 Share

Recommended Posts

That line that rolls through tomorrow evening is going to pack a punch in terms of rainfall intensity. Forcing and dynamics are enough to where there may be some embedded thunder/lightning but instability is quite limited. It is possible maybe within Fairfield County in southwestern Connecticut could see a localized damaging wind gust. Should see some gusty winds though for most out ahead of that line...nothing wild though...25-35 mph.

Seriously...I mean if this doesn't make it obvious then I don't know what will. 

BOS was -0.9

ORH/PVD about average 

I don't remember when ORH was looked at/corrected and I thought there were some questions too...but BDL somehow getting +1.2 when these other sites were not even remotely close...bogus. It's just crapping up the data base.

I had +2 to +4 for DM. Hopefully March corrects back a bit warmer.

I'm ready for the warm. My 20 minute infatuation with March 9 is over. It was cute to have some fun with it and get all aroused with fantasy but time to revert back to reality.

Wow...I thought the 12z NAM was wet for tomorrow but then I compared to 6z and 0z and didn't realize how wild the 6z was with rainfall totals. I would have to think there could be some minor flooding concerns tomorrow if the NAM is correct. 

Have the ham radio at the ready.

Most guidance is in the .50-1” range. . A little more to the west of us. Another meh event

I think that makes the most sense. There may be some convective feedback going on with the NAM. The NAM seems to want to slow the progression of everything a bit and then develops a few weak waves (which could be convective feedback) and prolongs the heavier precipitation with some back building.

So Am I correct in saying that the GFS seemed to be more correct this winter with the cold temperatures over the Euro forecast. Where the Euro was much more reliable when it came to showing the big storms being a miss are going to our South ( Where's the GFS kept showing these big bombs hitting us before finally backing off )

Actually scratch that...I totally assessed this incorrectly. That main slug of heavy rain moving through, while there may be some embedded convection, any risk for strong wind gusts is actually tied into the potential for scattered thunderstorms to re-develop behind that area...but that doesn't apply to us, that will be more central PA like what is advertised on the HRRR

Tracking spring's arrival ...

  ... Thursday mid day to late afternoon looks spectacular on this 12z NAM FOUS grid.   +7 at 900 mb and +2 at 800 mb, with at least partial sun - whatever the machine guidance has, you go above it by a click or two.   I checked the 500 and 300 mb relative humidity and they are <50% so the cirrus pollution will be minimal.  

That all spells probably the first maxing of a mixing level due to daytime heating.   If we get +5C at 850 in that general synopsis we'll be near 70 in the 2-meters

Granted, this is just the NAM ... but I'm imagining what that will be like.  It's been months since any temperatures even close to that - it will be a 'spring fever' at least for

Here comes our best thunderstorm of the year.
