.DISCUSSION...
(This evening through next Tuesday)
Issued at 206 PM CDT Wed Sep 18 2024

Fog last night never ended up materializing as forecast
in yesterday`s afternoon package, likely due to dry air moving in
from the northeast. A swing and a miss. Other than the removal of
widespread fog, the remainder of the forecast has generally
remained unchanged. Blocking to our east has persisted and a
shortwave trough has ejected from the rockies over the northern
Plains which will move into Canada today. Therefore, it is still
expected that weather will be quite persistent through this
weekend. Expect highs to be in the upper 80s and low 90s with lows
approaching 65 to 60.

Model guidance has come to a consensus that the Appalachian
trough will be slowly ingested into the broader westerly flow by
Sunday. With the lack of significant blocking, a second trough,
which is behind the on in MT today, will eject from the rockies
and move east. At this point, ensemble spread drastically
increases in both the position/amplitude of this wave, but it
brings our next best chance at precipitation early next week.
But again, it is still too soon to speak on specific impacts.
