.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
Highly variable cigs and vsbys for the mid to late morning in
radiational/valley fog regime with vsbys ranging from 1/4SM to
2SM+ in just a few miles. In any event, all TAF sites in Central
and Western PA will be MVFR or better by 14Z today, while KLNS
may stay MVFR w/respect to CIGS for the entire daylight hours
today.
While VFR in a SCT/BKN stratocu cloud deck will be the
prevailing conditions today, some isolated showers are possible
in the afternoon. Chances for this are highest at MDT and LNS
with spotty morning activity possible as well. This activity may
lead to bounces between VFR and MVFR throughout the day
tomorrow in the southeast, with greater restrictions more likely
at LNS.
This showery activity will be ahead of a cluster of storms
moving through in the evening/early night along and ahead of a
cold front. Have updated PROB30s for -TSRA to reflect most
confident timing at the current moment. HREF ensemble and NBM
trending later in storm timing in their most recent runs. Should
a strong core cross paths with an airfield, brief IFR
restrictions are possible.
Outlook...
Sun...Restrictions possible, mainly NW in SHRA. Improvement
elsewhere.
Mon-Wed...Patchy morning fog, otherwise mainly VFR conditions
return early next week.
