.AVIATION /00Z MONDAY THROUGH FRIDAY/...
Shower/thunderstorm activity will gradually diminish this 
evening along the north-south moisture/convergence boundary 
near KIPT/KMDT/KLNS, with largely rain-free conditions elsewhere
through tonight. Localized MVFR-IFR restrictions would be 
possible underneath these cells, though confidence in these 
pulse-y cells being overhead at KIPT/KMDT/KLNS is too low for 
TAF inclusion (<30% chance). Otherwise, patchy fog is expected 
overnight given light/variable winds and the gradual uptrend in
low-level moisture over the past few days, with highest 
confidence in overnight fog currently for KBFD.

Patchy morning fog will give way to primarily VFR conditions
during the daytime on Monday, with scattered showers/storms
ahead of a shortwave over the Great Lakes & Ohio Valley
bringing another chance for localized MVFR-IFR restrictions. 
Meager deep-layer wind shear (0-6 km shear around 15 kts) will 
support pulse-y cells/clusters, with typical summertime moisture (PWATs
of around 1-1.5") and a well-mixed boundary layer (0-3 km lapse
rates of around 8-9 C/km) driving the chance for visibility 
restrictions and localized wind gusts. Chances for TSRA at any 
one terminal is around 30% at this time, given the broadly 
supportive yet diffuse lifting mechanism at play.

Outlook...

Tue...Restrictions likely with scattered -SHRA/-TSRA.

Wed-Thu...Restrictions possible as -SHRA/-TSRA becomes less 
numerous. Patchy overnight fog possible.

Fri...VFR favored with slight chance for -SHRA. Patchy overnight
fog possible.
