National Weather Service weather radar data was collected to determine the origin, aerial coverage and depth of snowsqualls that occurred on fifteen separate days over southern New England. These squalls were found to begin upstream from the Great Lakes region from Canada, and then track east-southeast into New England. Observations along with surface and upper air charts were analyzed. Westerly flow at 500 mb with a 500 mb low centered over the Hudson Bay, along with a surface cold front or trough and cold air advection at 850 mb were three similar features found in each case. The Weather and Research Forecast (WRF) model was mn to further analyze the wind fields at all levels look for areas of convergence along the squalls, and fend evidence of intense snow growth regions.

The results show that these events can be readily forecasted using typical global forecasting models in conjunction with higher resolution mesoscale models such as the WRF.
