Maybe a few rogue strong storms around later Tuesday. We'll see convection with the front on Wednesday but anything severe would be isolated and relatively brief. Would be more intriguing if lapse rates were a bit more respectable. 2 Link to comment Share on other sites More sharing options...

weatherwiz Posted 4 hours ago Author Share Posted 4 hours ago Well I'm very curious to see how well NBMv5 performs. 7z NBM for BDL has 99 for a high tomorrow (though highest 3-hr temp is 94) with a low of 73. MAV is 92/67 MET is 91/68 Link to comment Share on other sites More sharing options...
Typhoon Tip Posted 4 hours ago Share Posted 4 hours ago Welp .. 75 here as we pass into the 10am hr "10 after 10" puts us in the 80s ... but being on the north side of a sag front that has observable site winds coming off the ocean. That says no...but, temps rising unimpeded as trend says yes. Minor competing signals there. I guess the wind being very light, in the 10kt range may not be enough. It's like you could work it out mathematically. Determine what the necessary E wind strength has to be during the solar max in order to overcome diurnal heating. I bet 10 kts isn't enough? Something like that. The shallow boundary is already apparently coming back as a warm front, according to WPC ... the previous update had this as a cool front where it is now warm in CT. I guess the late high T surge idea of the NAM has legs. Link to comment Share on other sites More sharing options...

I guess the late high T surge idea of the NAM has legs. Great point on this...strength of the flow certainly does factor in. Also, in this case as least that boundary is probably so shallow and weak that its just totally mixing out Link to comment Share on other sites More sharing options...

MAV is 92/67 MET is 91/68 I suspect we get heat advisories added in the springfield to HFD and also metrowest of Boston for tomorrow. The 2ms appear under cooked for the fact that the 850 mb will be reached as the mixing depth and I'm seeing 19C at that level on some of this guidance. All but compelled to add 2 point bump out of respect for superb heating combined with "non-Markovian" feedback, no less. Link to comment Share on other sites More sharing options...

CT Rain Posted 2 hours ago Share Posted 2 hours ago Wednesday's severe threat looks decent to me. Lapse rates are pretty good (6.5c/km) on the NAM and deep layer effective shear around 40 knots. Should be able to get a decent QLCS with some embedded supercells. I think the GFS is mixing out the boundary layer a bit too much. 4 Link to comment Share on other sites More sharing options...
weatherwiz Posted 2 hours ago Author Share Posted 2 hours ago The NAM is actually pretty interesting for Wednesday. Would suggest a threat for scattered damaging wind gusts, particularly south of the Pike. The NAM has a large area of steeper mid-level lapse rates overhead, shunting south during the day (hence south of the Pike favored). Not sure I totally buy this though...the NAM seems to have a tendency for having these areas of steeper lapse rates...but a big player in this is whether the airmass over the OV is convectively overturned tomorrow night into Wednesday morning. Shear is pretty decent along with height falls and looks like we get enough heating to drive up the llvl lapse rates 2 Link to comment Share on other sites More sharing options...

Would actually see a pretty solid line drift south and it occurrs during peak heating 1 Link to comment Share on other sites More sharing options...

CT Valley Snowman Posted 2 hours ago Share Posted 2 hours ago 90 yesterday. Currently 85. Let's see if we can pull off another one here this afternoon. Tuesday is a lock and Wednesday looks promising for 90 here. A 4 day May heatwave would be sweet. Hoping for a nice banger on Wednesday and then Stein gets his webbed hands into this weekend. Can't see how anyone would route for cool/wet on MDW, including ACATT. 1 Link to comment Share on other sites More sharing options...
weatherwiz Posted 2 hours ago Author Share Posted 2 hours ago I think we'll see widespread storms...should see a solid line evolve ahead of the front. Only question is whether damaging wind gust potential is rather isolated or more scattered Link to comment Share on other sites More sharing options...

CoastalWx Posted 1 hour ago Share Posted 1 hour ago Yeah I thought Nam was decent too. I don’t think it’s widespread, but probably a couple of segments in the line that get strong. Link to comment Share on other sites More sharing options...
Typhoon Tip Posted 1 hour ago Share Posted 1 hour ago Borderline big heat tomorrow. As expected ... headlines now flying. Prooobably 94 to 95? 95+ is sort of the "unofficial" "big heat" criteria.
