.DISCUSSION... Issued at 156 PM EDT Sun Sep 7 2025
For those areas that enjoyed a brief shower over the past 12 to 18 hours, count your blessings as this may very well be the only rainfall for the next 7 or more days. Sct cu rapidly developed mid morning downwind of Lk MI, but should quickly dissipate by sunset allowing for one more cold night by early Sept standards. As has been mentioned in past days a few locations in our far NE could see temps briefly dip into the upper 30s, but for the most part low 40s will be common.
Monday will feature the start of warmer temperatures that will then settle in through the remainder of the period. Highs will still be below normal (around 70) Monday, but rapidly trend above normal in the low to mid 80s by mid week and linger in that range through the upcoming weekend. A series of troughs will help keep the much warmer temperatures confined west of the region, but the chances for precip that would normally accompany them are unlikely to occur as deeper moisture remains cutoff to the west or down along the Gulf states. As a result, measurable pops remain limited under 15%.
