.DISCUSSION...

Issued at 317 AM EDT Wed May 6 2026



Anomalously chilly air will prevail over the region through

Friday as an upper low lingers over Hudson Bay. This low brought

showers and chilly air to the region yesterday behind a cold 

front. The cold air will bring the likelihood of frost formation

tonight especially north of Highway 30 as temperatures drop 

into the 30s. Highs both today and Thursday will only be in the 

50s. Pondered headlines for this upcoming night with surrounding

offices - the consensus was to defer any headlines to the 

dayshift. The possibility, extent and amount of cloud formation

tonight under the high-based subsidence inversion will make low

temperature forecasts challenging.



A milder and more unsettled pattern is farther ahead into early

next week as the upper level trof over the Great Lakes region 

shifts east and as the upstream flow becomes more zonal. Ample 

upper level disturbances will travel east in the upper flow and

bring chances for showers. At this time, severe weather chances

appear low.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...

Issued at 1243 PM EDT Wed May 6 2026



VFR conditions to dominate through the period with winds

generally on the lighter side until Thursday when a disturbance

approaches and allows for some increase. Models indicate an area

of rain with this feature, but trends suggest it remains SW of

both locations (including any possible flight impacts).
