.DISCUSSION...
Issued at 152 PM EST Mon Nov 2 2026

- Rain chances Wednesday then turning cooler

Moisture increases in southerly flow through Wednesday with height
falls as upper low approaches, but chances for rain remain low
through Tuesday. The better chance for measurable rain is not
until Wednesday and even then it looks like heavy rain is unlikely
with convection remaining south of the forecast area and dry
slotting occurring rather quickly.

Wraparound, lake-enhanced showers, along with cooler temperatures
can be expected through the end of the week as upper troughing
remains and is eventually reloaded this weekend by a vigorous
northern stream shortwave trough. Current slight chance POPs for
the weekend may eventually trend higher given decent ensemble
support got the timing and location of this trough.
