.You can not only check weather, but file flight plans through DTC DUAT (DUAT.com) or CSC DUATS (DUATS.com). Both companies are approved by the FAA as weather sources and — perhaps more important — are independent of the FSS. You can go online to get continuously updated weather information and file, and close, flight plans. Other information, including pireps, NOTAMs and more, are available from both of these companies.
