First here is last year's verification of the GFS vs ECMWF:

 

Number of times GFS has forecast a high of 100F or higher:  48  (9 more times than 2020)

Actual number of highs 90F or higher:  36

 

Number of times ECMWF has forecast a high of 100F or higher:  1 (17 less than 2020)

Actual number of highs 90F or higher: 0

 

Number of times GFS has forecast a high of 100F or higher within 10 days: 20

Actual number of highs 90F or higher: 19

 

Number of times GFS has forecast a high of 99F :  44

Actual number of highs 90F or higher:  39

 

Number of times ECMWF has forecast a high of 99F :  1

Actual number of highs 90F or higher:  1

 

Number of times GFS has forecast a high of 99F or higher within 10 days: 39

Actual number of highs 90F or higher: 39

 

Number of times GFS & ECMWF forecast 100F on the same day within 10 days: 0

 

Number of 100 degree days at PHL: 0

Well maybe it is different this year.  If only we had some other place to see how the GFS is doing...

BTW yes this was the most egregious run I caught, but not the only run it pez dispensed 100s for JAX.

Going back to alphanumerics now instead of graphs.  Good luck with that GFS.

This may be an all-time high for RDU and not in la-la land either.  Euro 100F, GGEM 98F.

It has been exceptionally dry down there this spring so if that torch airmass moves in for a few days 100+ seems likely in the Carolinas.

Allan (Huffman) predicted a 101F top for Raleigh this morning.  My money would be that Allan will be closer.  I know you are not saying 108F or higher.

I think the 18z run today (12th) has a chance to add to this list.

No, just saying widespread lower 100s (100-104) in the Carolinas seems obtainable if things hold as is.

12z jumped on it already, 18z probably will have a 2 or 3 days of 100F...

I was wrong about the 18z run today, highest predicted temp only 97F on the 21st.
