Hoosier Posted July 21, 2016 Author Share Posted July 21, 2016 Pretty oppressive out there. Cell popped up to my west and may provide a brief cooldown once it gets here but possibly make it more muggy. Link to comment Share on other sites More sharing options...

purduewx80 Posted July 21, 2016 Share Posted July 21, 2016 next MCS is probably in its beginning stages east of the twin cities. should ride the old outflow se/sse this evening. the effective front may not make it back north of chicago until the weekend. given how high dews already are, how they will tend to pool along the warm side of the outflow boundary, and the wetness of the past few weeks over the corn belt, think it's possible we see some legit mid-80s dews show up this evening.

RCNYILWX Posted July 21, 2016 Share Posted July 21, 2016 Somebody needs to look into what's been going on with dewpoints in Gary. Now 91/84 there.GYY is garbage because the obs are called in by the tower and they basically guess at what's been occurring over the past hour. Not sure how much the AWOS is used. It's why their wind obs are always junk. I haven't been paying close enough attention, but see if the dew points have still been unrealistically high when the 20 minute obs come in while the airport is closed.

Might as well just rely on some of the personal weather stations in the area...can't be much worse. Link to comment Share on other sites More sharing options...

It's unfortunate because it's out of our hands really. We've sent emails with collections of wind obs to the central region of the NWS to hopefully persuade a change if they discuss it with the FAA but it hasn't happened yet. In this case it's possible there's some contribution from the AWOS being out of calibration with the dewpoints but it's hard to tell. Link to comment Share on other sites More sharing options...
madwx Posted July 21, 2016 Share Posted July 21, 2016 The 0Z sounding from DVN might have some insane value of CAPE, will be interesting to see what it is Edit: Looks like the all time record SBCAPE value there is 7701 j/kg Link to comment Share on other sites More sharing options...
