.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 /06Z TAFS THROUGH 06Z THURSDAY/...

Issued at 142 AM EDT Wed May 6 2026



A low level frontal boundary and associated stronger low level

frontogenesis forcing will continue to sag southeast through the

remainder of the overnight hours. Some light rain may clip KFWA

vicinity through 07Z or 08Z, but overall trend should be for

rain focusing south of the terminal as this frontogenesis axis 

slips south. The lagging primary upper level trough will shift 

across the southern Great Lakes Wednesday evening but will be 

moisture starved by this time. After a decrease in morning 

clouds, some increase in mid level clouds is expected today in 

advance of the upper level trough, but VFR conditions should 

persist through the period. In terms of winds, a sfc trough axis

across central Lower Michigan will gradually lose its integrity

this morning with a weak westerly gradient maintained through 

the day across northern Indiana. This should support west-

northwest winds of around 10 knots during peak mixing today, 

becoming light and variable this evening.
