.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Low pressure and a warm front are tracking through the
Commonwealth today and bringing rain, the possibility of
thunderstorms, and widespread restrictions in the near term and
overnight. 

The initial wave of showers is moving off to the east and
redevelopment is occurring in SW PA in the form of scattered
showers. While exact timing is uncertain regarding how long any
showers/thunderstorms will persist in any region, these storms
are likely to, in some capacity, restrict all airfields with 
the lowest confidence in Bradford. 

Visibility restrictions to IFR is possible with any of the
showers or storms that pass through, given robust moisture in
place, along with MVFR cloud bases with some potential for IFR 
bases. Ceilings overall will lower as the day progresses into
night though even after convection has left our area. IFR
restrictions from these ceilings are expected across the whole
area spreading north to south as the evening/night progresses.
The best chance for overnight LIFR at this time is at BFD and
JST.

Visibility restrictions are anticipated as well. Cloud cover is
likely to preclude widespread prevailing fog below IFR 
threshold. Mist though is expected with all of the lingering 
moisture which will see likely lead to restrictions as well, 
mostly in the MVFR category at this time. However with such 
robust moisture in place, widespread drops in visibility further
into IFR cannot be ruled out.

Conditions will improve starting around 12Z tomorrow at BFD and
spread eastward in the form of visibilities improving and
ceilings moving up as clouds show signs of thinning.


Outlook...

Tue...Lower chances of showers, mainly VFR.

Wed...Mainly VFR, dry conditions expected

Thu...Restrictions possible in another round of 
evening/overnight precipitation

Fri...Restrictions possible in another round of daytime/evening 
showers.
