.DISCUSSION...
Issued at 209 PM EDT Wed Oct 15 2025
Upper level forcing proved dominant this morning resulting in a
fairly large area of light rain. Hardly a drought buster, but
welcome nonetheless. The shortwave responsible is now east of the
Great Lakes and high pressure is slowly settling in. Plenty of cloud
cover remains but time height cross sections do indicate skies
gradually clear tonight. Can`t completely rule out at least patchy
fog tonight over far northeast Indiana and adjacent areas where
there is not only renewed surface moisture but small dew point
depressions as well.
Sunshine, upper-level ridging, and southerly return flow off
surface high pressure will permit high temperatures closer to 70
Thursday. This brief warming trend continues into Saturday as the
upper-air pattern becomes highly amplified with a towering ridge
over the Midwest and a deep low over Wyoming. This low eventually
wraps up over the Canadian Prairie but its trailing cold front moves
through our area later Saturday and Sunday. This cold front becomes
the focus for cyclogenesis in conjunction with a strong
shortwave dropping in across the Central US. This storm system
would bring much- needed rain to our area along with some
thunderstorms (instability is a limiting factor). Depending on
the track and depth of the surface low, it could be windy this
weekend with gusts in excess of 30 mph possible, especially
Sunday as the low departs.
Sharply cooler behind this storm system with high temperatures
struggling to reach 60 degrees to begin the new week. Additional
rain chances are possible near Tuesday/Wednesday as progressive
upper-level flow continues.

Issued at 1221 PM EDT Wed Oct 15 2025
MVFR to low VFR cigs will linger this afternoon behind a cool
front. Drier air funnels in otherwise tonight into tomorrow as
weak high pressure drops southeast into the lower Great Lakes.
Winds will be light and out of the east-northeast through the
period.
