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. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
