concentrations within the region may become unhealthy for
sensitive groups. Sensitive groups include children, people
suffering from asthma, heart disease or other lung diseases,
and the elderly. The effects of air pollution can be minimized
by avoiding strenuous activity or exercise outdoors.

From: Jan 07, 2026 10:47
Until: Jan 07, 2026 15:00
Special Weather Statement
Isolated pockets of dense fog will reduce visibility to a quarter
mile or less in spots early this morning. If traveling, be
prepared for changes in visibility over a short distance
especially on ridgetops or in river and stream valleys. The fog
will dissipate and visibility will improve shortly as the wind
picks up and helps to warm the temperatures. In addition, there
are a few places where the temperature is right around freezing,
mainly near York and Hanover. The fog may freeze onto surfaces at
those temperatures, so be on the lookout for icy patches, too.
From: Jan 07, 2026 10:20
Until: Jan 07, 2026 14:00
Dense Fog Advisory
* WHAT...Visibility one quarter to one half mile in dense fog.
* WHERE...Portions of central and northern Delaware, northeast
Maryland, central, northern, northwest, and southern New Jersey,
and east central, northeast, and southeast Pennsylvania.
* WHEN...Until 8 AM EST this morning.
* IMPACTS...Low visibility could make driving conditions hazardous.
From: Jan 07, 2026 05:12
Until: Jan 07, 2026 13:00
Special Weather Statement
A strong cold front moving in will help to generate a line of
heavier snow showers and possibly embedded dangerous snow squalls
across northwest and central Pennsylvania.
We expect heavy snow showers and possible squalls to be on a line
from:
* Near Coudersport to Bradford to Warren between 10 and 11 pm.
* Near Mansfield to St. Mary's to Dubois between 11 pm and
midnight.
* Near Jersey Shore to Lock Haven to Clearfield between midnight
and 1 am.
* Near Williamsport to State College to Altoona to Somerset between
1 and 2 am.
* Near Bloomsburg to Harrisburg to Mechanicsburg between 2 and 3
am.
* Near Lancaster to York between 3 and 4 am.
If snow squalls develop, they will last for up to 10 to 15
minutes in any one location, with up to a half-inch to an inch of
snow in that timeframe, along with possible wind gusts of 30 to 40
mph.
This would result in a quick reduction in visibility and
perhaps localized icy roads, should a flash freeze develop. Low
traction and blinding visibility of a snow squall can make travel
very dangerous very quickly. If this combination of ingredients
becomes imminent, snow squall warnings would be issued, with very
specific information on timing, movement, and portions of
interstate highways to be affected.
Please monitor the latest conditions in your area overnight if you
will be out driving. Use extra caution if you must travel into a
snow squall, slow down, and consider exiting the highway. Rapid
changes in visibility and potentially slick roads may lead to
accidents. Please use extreme caution and allow plenty of stopping
distance. Avoid braking suddenly.

From: Dec 30, 2025 07:42
Until: Dec 30, 2025 17:00
Special Weather Statement
Strong west-northwest winds and moisture streaming off the
relatively warmer waters of the Great Lakes will generate narrow,
slowly-meandering bands of briefly heavy lake effect snow. These
snow bands will impact portions of I-99 in Blair and Centre
County between mile markers 15 and 85, I-80 between mile marker
138 and 193, as well as roadways in Huntingdon, Cameron, Clinton,
Mifflin, Lycoming Tioga, Sullivan and Potter counties for the
next several hours.
Bands of lake effect snow can quickly reduce visibility and cause
rapid accumulations of snow greater than one inch per hour. The
reduced traction and blinding visibility of a snow band can make
travel very dangerous very quickly.
Use extra caution if you must travel this morning. If you encounter
bands of heavy snow, slow down, turn on your hazard lights and
consider exiting the highway. Rapid changes in visibility and
potentially slick roads may lead to accidents. Allow plenty of
stopping distance between you and the vehicle ahead. Avoid
braking suddenly.
