I think mine looks alright.  But unsure of something...if you see some station pressure that are like 1006mb and then 1003mb can you still draw in the 1004mb isobar even though there is no station which has that reading?  I'll post my map for reference...I have my isobars for western and central CT but nothing in eastern.  Also, if the pressure is 1008.3 would I not draw the 1008mb contour right through that station or should it be off to the side a bit?

Dude...you have 1008 cutting through the 083 and 088 plots. Keep in mind those are 1008.3 and 1008.8

 

I corrected that.

Man...never realized how "difficult drawing this stuff is.  Should have practiced years ago.  Doesn't help I have horrid art skills.  My cold front is a little bent in the center

Just saw your last sentence. You have to look at the values in the plot and sorta visualize where the contour would fit in between. Obviously you'd draw the 1012 contour halfway between 1011.0 and 1013.0 plots. If the plots are 1011.7 and 1012.9 you'd obviously draw it much closer to the 1011.7 than the 1012.9.

You have the 1012 going through the 1012.3 when it should be closer to the 1011.8 than the 1012.3.

Be careful about putting ctours where you dn't have data to prove it. You have a small zone there of 35F in N-C CT with no obs of <= 35F there.

 

ahh ok.  I had just assumed there may be a 35 there given how there are obs of 32F and 33F to the north and 36F and 38F south of that

You wouldn't put it above those 2 37s though...you don't know by the map what's happening north of there. Keep the 35F contour in NW CT.

That pine appears to be farther away.  The shorter trees between it and the taller tree to it's left (as seen on-screen) weren't moving much, either.  Sometimes, gusts of straight-line winds can be quite narrow.  After the July 1999 derecho, I saw in Eustis a strip of flattened red pine, a relatively windfirm species, that was about 80 feet wide and 600 long, with undamaged trees on either side.

Thanks!

I just watched that :lol:

I did find something helpful...wasn't sure when to apply the "10" and the "9" before the 3-digit number but now know but I've never really done this so not very confident I guess

Yeah, the 10 vs. the 9 is pretty much whatever keeps the pressure closest to 1000 mb. You are (slightly) more likely to have a 960 mb pressure than a 1060 mb pressure for instance.

And Brian covered this is good detail. You keep your 1008 isobar a proportional distance between the two points in question. 

Don't worry though, we all could stand to do a little more hand analysis.
