The extended range GFS and NBM (National Blend of Models) shows a high of about 32 for Philadelphia on Thursday! Actually, that’s an improvement; the forecast dip was even more amplified just a few days ago.
A warm up and rain is expected next Sunday or Monday, then a return to colder conditions sometime during the following week.
[su_note note_color=”#d9f2da”]I continue to feel we will have a colder than average winter due to the nadir in the sunspot cycle and a stormier winter as well, with plenty of moisture available in the southern jet stream from a developing El Niño in the Pacific.
I first made this preliminary climate prediction a few weeks ago. Past information about the sunspot cycle’s influence on temperatures can be found here.[/su_note]
