.DISCUSSION...
Issued at 1244 PM EDT Wed Oct 1 2025
Slightly cooler temperatures today and again tomorrow in the
wake of the weak cool frontal boundary that has brought
increased high cloud cover to the area today. However, highs
today and tomorrow in the upper 70s to lower 80s are still
about 8 to 11 degrees above normal and will see another rebound
in temps beginning Friday through the weekend as a higher
amplitude upper level ridge surges northward across the midwest
and Ohio River Valley and even well north into central Canada
into the Hudson Bay region.
Highs on Friday and Saturday will get well into the mid 80s.
Sunday and Monday may be a couple degrees cooler with synoptic
heights shrinking ahead of a trough originating over the Gulf of
Alaska and dropping east and southward into the central
Canada/CONUS early next week. A cold front associated with this
system looks to move through the area late Monday night into
Tuesday morning. This will bring cooler temperatures and chances
for some light rain showers on Tuesday and Wednesday. Highs on
Wednesday will only be in the mid to upper 60s.
