.DISCUSSION... Issued at 208 PM EDT Fri Sep 26 2025
Prolonged stretch of pleasant weather the story through next week as a dry and stable air mass holds firm with ridging the dominant feature locally in an increasingly blocky flow regime. Into this weekend, the area will be in between upper troughing settling into the southeast US and a round of height falls progressing east through Ontario and Quebec. This shortwave jet energy will send a dry frontal passage south into Michigan, possibly washing out in our far north by early Sunday with no sensible wx impacts. A pseudo omega block then emerges with anomalous ridging developing from central Canada south into the Great Lakes, which likely holds a tropical system/upper trough merger over the southeast US. The net result is above normal temps and dry conditions through the forecast.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 730 PM EDT Fri Sep 26 2025
VFR conditions should dominate most, if not all of the period at both locations. For the time being, have continued to leave any fog mention out with a good deal of drying of the boundary layer taking place today. If it does develop, it should be rather shallow in nature, causing highly variable vsbys in the 9-13Z time frame.
