Found this interesting
Low confidence forecast continues Friday into next weekend as a
boundary will be separating very cold air/below normal temperatures to
our north and unseasonably mild temperatures to our southwest. There
is a high across Quebec and pattern recognition would indicate good
support for shallow cold air to invade southern New England. The 12z
ECMWF is most aggressive with the shallow cold air...especially on
Friday with daytime temperatures mainly in the 20s! Meanwhile...the
12z GFS is the mildest of the guidance with temperatures at the same
time in the 50s! The interesting thing is that the GFS AI model is
much colder and more similar to the ECMWF. Assume it is probably an
indication of past performance/pattern recognition. While we are not
sure it will be quite as cold as the ECMWF...we certainly want to
lean colder based on pattern recognition and support from the AI
guidance. But again...tremendous uncertainty continues in this
forecast.
