.AVIATION /00Z MONDAY THROUGH FRIDAY/...
VFR conditions will persist through at least the first half of
tonight with a very light north to northeast breeze going calm
at most airfields by shortly after midnight. 

A strong signal for fog continues in much of model guidance 
this evening; thus, increasing confidence in fog impacting some
subset of airfields across the region.

Best chance for fog and a 2-3 hour period of LIFR/VLIFR
conditions will be at BFD/UNV/IPT while a briefer period of 
fog is expected at AOO. 

The lowest confidence of any fog formation will be at LNS with 
current thinking that JST/MDT remain VFR by Monday morning. That
being said about all of the fog mentions, there is a solution 
where dry air wins out and fog potential across the area remains
minimal but that appears to be a lower confidence solution at 
this time. 

Widespread VFR will return to the area by 13-14Z Monday with 
those conditions continuing through the end of the 00Z TAF 
package.

Outlook...

Tue...AM valley fog possible; otherwise predominantly VFR.

Wed...Primarily VFR, although late-day SHRA/TSRA possible 
across the northern tier.

Thu...Cold FROPA could bring scattered SHRA/TSRA areawide.

Fri...Primarily VFR conditions, some potential for afternoon
SHRA/TSRA but uncertainty remains high.
