Global Forecast System (GFS): The Global Forecast System (GFS) - The GFS is a global spectral model used primarily for aviation weather forecasts. The GFS provides guidance out to 384 hours at 00, 06, 12 and 18UTC.
European Center for Medium range Weather Forecasting (ECMWF): Contour plots from the European Center for Medium range Weather Forecasting (ECMWF) forecast model. This model runs to 10 days (7 days public) and provides data at 24 hour intervals for sea level pressure, 850 mb winds and temperatures and 500 mb heights. These plots are generated once a day at approx 8:45 PM EST.
RGEM: 00z Initialization | 12z Initialization Short-range regional forecast model from CMC Environment Canada. 48 hour forecast updated twice daily (00 UTC and 12 UTC).
GGEM: 00z Initialization | 12z Initialization Medium-range global forecast model from CMC Environment Canada. 240 hour forecast updated twice daily (00 UTC and 12 UTC).
North American Mesoscale (NAM): The NAM model is a regional mesoscale model using enhanced terrain and improved parameterization of surface and precipitation processes. It produces forecasts out to 84 hours at 00, 06, 12 and 18UTC.
UKMET: The UKMET has a resolution of 75 kilometers, which is better than the GFS resolution of 150 km. The model also gives forecasts for the entire northern hemisphere like the GFS. The UKMET is run twice a day
Rapid Update Cycle (RUC): The RUC is a hybrid sigma-isentropic analysis and forecast system. It utilizes a 3-hour, OI-based data assimilation cycle to produce 12-hour forecasts eight times per day. This is a 25-layer model with 60 km resolution.
Canadian 6-10 Day and 8-14 Day Outlook: The CPC Oulook is a 6 to 10 and 8 to 14 day temperature and precipitation probability outlook from the Climate Prediction Center.
Canadian Snowfall/Freezing Rain Probability Forecasts: These charts indicate the probability (potential) for a location to receive specific thresholds of accumulated snow or freezing rain (ice).
Low Pressure Track Forecasts: Forecast surface low pressure tracking (ensemble clusters).
