KEY MESSAGE 1) With the remnant low level moisture and wet ground, a signal exists for some fog development overnight. Have added fog to the forecast with the best threat for dense fog over eastern portions of ILN/s area where the best low level moisture lingers. KEY MESSAGE 2) Dew points will drop back into the 60s in the wake of today`s cold front, and temperatures will fall to or a bit below normal. Moisture will increase on Wednesday ahead of an approaching cold front, although not to the degree that has been the case for much of the past week. The front will sag through the area Wednesday night into Thursday morning as minor impulses of energy move through the base of a long wave trough that slowly shifts east. Showers and possibly some storms could linger in southern counties into Thursday night when a more energetic short wave move southeast into the Tennessee Valley giving the front a stronger push south. After this front passes, a northwest flow develops and even cooler conditions will prevail through the end of the week with highs in the mid 70s to around 80 and lows in the mid 50s to lower 60s. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/... Clouds will scatter out this evening as the sun sets. With the wet ground and persistent low level moisture, have kept areas of fog in the TAFs for late tonight. This will burn off early Tuesday leading to fair weather cumulus clouds for the rest of the period. Winds will be rather light out of the northwest.
