.DISCUSSION...
Issued at 128 AM EDT Tue Jul 8 2025

An area of dense fog had developed over the northeast corner of
Indiana early this morning north of Auburn in the vicinity of
Angola where skies had cleared and winds had become calm. The
fog should be relatively shallow and mix out by 9 AM EDT.

There will be a steady stream of pacific energy topping the upstream
subtropical ridge and reaching the forecast area into early next
week. This energy in the form of upper level disturbances (vort
maxes) and upper level trofs will continue to enhance the chance for
thunderstorms. The strongest upper level trof will reach the area
Friday. This system will bring the greatest chance for rain through
early next week; however, rainfall amounts at this time are only
be expected to be up to a quarter of an inch. Otherwise, the
very warm and humid conditions will persist for the next 7 days
with highs in the 80s. Heat indices will be highest Friday and
Saturday afternoons with values from around 90 to 95.

IFR/MVFR categories for KFWA in patchy mist/fog still possible

through the forecast period for both TAF sites. Isolated
showers/t-storms are possible late in the period however very
low confidence in this outcome so have left mention out of the
