THE NATIONAL WEATHER SERVICE - Our Mission


The National Weather Service (NWS) provides weather, hydrologic and climate forecasts and warnings for the United States, its territories, adjacent waters and ocean areas for the protection of life and property and enhancement of the national economy. NWS data and products form a national informational data base and infrastructure, which can be used by other government agencies, the private sector, the public and the global community.


 
NWS FORECAST OFFICE -State College, PA

Take a Virtual Tour of our office!

Serving 33 counties in central Pennsylvania. See a map of our area of responsibility.

The NWS Forecast Office in State College opened its door in May 1993. Presently, there are about 25 employees who serve 33 counties in central Pennsylvania.

The Office Management Team oversees all office activities.

Our Forecasters work on rotating shifts 24 hours a day, 7 days a week to produce all the forecast and warning products issued by the office.

(Incoming meteorological and hydrological data, including river and stream gage information, also are monitored around the clock.)
 

Electronic Systems Analyst and Technicians ensure that all electronic equipment is functioning properly.

Volunteer Cooperative Weather Observers provide daily local weather and river reports from around central Pennsylvania. This network of volunteer observers is coordinated by the NWS Forecast Office in State College.

PROGRAMS
Forecasts, Watches, Warnings, Advisories and Outlooks
Our most important function is to issue weather forecasts, watches, warnings and advisories for the 33-county service area in central Pennsylvania. Weather forecasts are issued four times daily for every county, with updates as needed. Warnings, advisories, watches and outlooks are issued when hazardous weather is expected or is occurring. Hazardous weather events include tornadoes, severe thunderstorms, flooding, snow and ice storms, high winds, extreme heat and cold, freezes and frosts.
 

Warnings & Advisories: issued when event is occurring or imminent, generally within the next 12 hours.

Watches: issued when event could occur within 12 to 48 hours.

Outlooks (long-term): issued when event could occur beyond 1 or 2 days.

Specialized aviation forecasts tailored for pilots also are issued for the following central Pennsylvania airports: Bradford, Johnstown, Altoona, State College, Williamsport, Lancaster, and Harrisburg International.

Warning Coordination and Outreach
To ensure that we remain responsive to the needs of our customers, we support a large warning coordination and outreach program, which is lead by the Warning and Coordination Meteorologist. Among the many program activities, we:
(1) ensure the quality of our products;
(2) ensure that the products are being received by our customers;
and (3) maintain our large volunteer severe weather spotter network, along with public service and education.

Our customers include the general public, along with local, county and state emergency management agencies and officials.

Scientific Research
To improve forecast and warning services for our central Pennsylvania service area, we are involved in various science research projects, which are coordinated by the Science Operations Officer. Given our convenient location adjacent to the Pennsylvania State University and the Middle Atlantic River Forecast Center, we are able to collaborate with researchers from both organizations.


Research projects range from observational studies designed to increase our understanding of how severe weather occurs in Pennsylvania to developing local, small-scale models of the atmosphere customized for our area.
 

HOW THE PUBLIC RECEIVES OUR PRODUCTS 
There is a wide range of dissemination systems available for the public to receive our products (forecasts, watches and warnings). The NWS web pages are the easiest way to get all the data we can provide. The National Oceanic and Atmospheric Administration (NOAA) Weather Radio (NWR) is probably the most reliable way to receive the fastest and most up-to-date weather information. 

The Emergency Alert System (EAS) receives specific hazardous weather warnings via NOAA weather radio, then relays those warnings directly to all TV and radio stations. TV stations can then display the warnings automatically, using a system that scrolls the printed warnings along the bottom of the screen. County and local emergency management agencies receive our warnings via specialized software packages such as the Emergency Management Weather Information Network and NOAA Weather Wire Service. Our routine, daily products (forecasts, climatological summaries, etc.) are available to every TV and radio station in central Pennsylvania.

 
THE LATEST TECHNOLOGY

The Doppler radar serving central Pennsylvania is located on Rattlesnake mountain in Black Moshannon State Forest northwest of State College.


The Advanced Weather Interactive Processing System (AWIPS) is a state-of-the-art computer system able to integrate and display a myriad of data. Forecasters use this system to view numerous meteorological data sets simultaneously. The system allows forecasters to compare observations, satellite and radar data to computer model forecast data, in order to produce more accurate forecasts.

NOAA Weather Radio: This automated voice system disseminates weather warnings more quickly than the previous manually produced broadcasts. 

During the modernization, powerful "Doppler" radars were deployed, providing radar coverage across the nation -- allowing forecasters to diagnose potentially severe storms by examining the structure and internal motions of the storms.
