May observations and discussions...

0z euro tried to get clearing into our area for the afternoon and the evening.

Looking at the visible satellite, I can see how that might occur in a few hours.

socked in here with sheet drizzle...hard to see how it happens, but maybe for parts of the area

The newly upgraded GFS brings a ring of fire MCS through the region on Sunday.

You can track the MCV from near Chicago later on Saturday. Around the end of

May last year we had a MCS roll through here very early in the morning. It will

be interesting to see how the updated GFS will do.

Some more breaks pushing into PA. I think we see more breaks like you mentioned thi afternoon.

Is this the first operational run since the upgrade? Not surprisingly, the 12z gfs made a huge jump towards the Euro/Euro ensembles handling of central Pacific ridge/upper level low diving down the west coast early in the period...This has huge implications on the pattern during and after the heat wave of course.

Wow,

That's cool to see such an immediate drastic difference from the 00z run in how it handled the west coast in the coming days, more like the euro ensemble mean.

I am glad to see the improvements. The comments in the main forum highlight some of the positives.

Definitely sounds like a defective Temp/Hum sensor. I am sure you tried the drain the ISS transmitter route & make sure connection on transmitter board is fine. Then reconnect and power back up transmitter. I had your issue with DVP1 before upgrading years ago to the DVP2! Time to call up Davis and have them send you a new one and send back the old one.

Thanks for the info. My outdoor temp/hum is working right now, almost immediately after the sun broke out in the past hour. Do you think the problem could be that I need a new lithium battery for the station? I put in a new temp/hum sensor about 3 years ago, so it just seems weird that I'd need to replace it again.

When you need to replace the lithium battery you will get a low battery message on the console. I've only had to replace the battery once in almost nine years.

Ok, thanks. It's most likely the sensor repeatedly drying out/getting wet then. Looks like I'll have to take the thing apart, which is always a pain in the arse.

Wonder what it would show for a real 100 degree day, 125+?

It's the same model that shows mid 20s at sea level with snow when there is literally no cold air source to be found for 1000 miles. Always fun to look at though.

John,

While the dgex has its value at times, I wouldn't put too much stok in its temp profiles in the medium range. Too many times I've seen it run WAY too high this year. Just my 3 cents...

The chance of storms today looks to be just inland away from the marine influence where the atmosphere

can destabilize more. Any storms will be capable of very heavy rains as they will be nearly stationary with

very light winds aloft.

That's according to the GFS.

Euro keeps the marine boundary east of the city and gets the city involved with convection this afternoon.
