.DISCUSSION...
Issued at 329 AM EDT Sat Jun 7 2025

Recent rainfall and light winds along with perhaps some
Canadian smoke have helped set the stage for widespread dense
fog in an area northeast of Warsaw and north of Fort Wayne
extending north in Lower Michigan and east into northwest Ohio.
Have issued a dense fog advisory for the dense fog until 9 AM
EDT. A small, but well-defined vort max (disturbance) will move
across the area tonight. This system was very distinct on
satellite (vapor) and was just coming out of the High Plains
early this morning. The environment ahead of this system will be
favorable for heavy rain, but limited severe storm potential
given high precipitable water values, weak low and mid level
flow and a saturated lower to mid atmosphere. Concern for
flooding given these favorable factors.

Otherwise, a deep upper level low will bring the chance for
showers and scattered storms from Sunday night through Monday.
Breezy conditions are likely Tuesday along with slightly cooler
temperatures. Showers and more storms are possible the rest of
the week, although there should be a diurnal flare with the
activity during the 19Z to 01Z window.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 150 AM EDT Sat Jun 7 2025

Inverted trough type feature at the southern extent of expansive
Great Lakes anticyclone will provide a favorable area for fog
development across northeast Indiana through early this morning.
Regional sfc observations have indicated an increase in LIFR/IFR
conditions to the north of KFWA, with a potential that these
conditions could affect KFWA by the 06Z-07Z timeframe. Once
these IFR/LIFR conditions move in, not much hope for
significant improvement until after 13Z this morning. The fog
potential appears to be much less for KSBN which is on the
western portion of the inverted trough axis with drier low level
air.

The next upstream short wave will bring another round of likely
rain to the terminals tonight, especially between 06Z and 12Z
Sunday morning. These will be addressed in more detail with the
12Z TAFs. At this time, expecting thunder to be quite limited in
coverage due to limited instability with northward extent
across far northern Indiana. Some increase in light northeast
winds is expected today as convectively enhanced sfc low
pressure upstream allows a slightly stronger low level height
gradient to take shape. Peak east-northeast gusts should be in
the 10 to 15 knot range.
