Even though we’re into fall now, a “last gasp” of summer will be the rule this week.
A warm southerly flow and upper level ridging make for a warm and humid combination, and that’s what we’ll get. The jet stream continues to carry cold fronts eastward and not in a southerly direction.
This may change by late this weekend with a shift to a more pronounced “north to south” upper level wind flow pattern (see map above). This would allow the end of September to end on a much cooler note. Two of the three computer models are pointing to this right now, but it’s still rather far away in time. I have moderate confidence that it will happen.
In the meantime, A/C or a good fan will surely come in handy.
