Feb 07, 13 The Storm Report Blog For February 7-9, 2013

Left Map Analysis: Looking at the latest satellite image, we can note two pronounced weather features, which are going to set the stage for a potent storm along the Northeast United States. The red circle is, as of 11AM on February 7, showing the latest position of the northern storm, which will start making its way towards the Northeast impacting places like Chicago and the Great Lakes. The yellow indicates where the southern storm is located, as this storm will move along the Northern Gulf and push towards the Northeast by this weekend.

Right Map Analysis: These are our latest predictions for the impacts that will be felt by this duo of storms. The Northern Storm is going to continue to impact the Great Lakes region with moderate snowfall, while the Southern storm system will bring moderate rain to the south before making its turn to the north. The dashed yellow lines are the two projected courses of the lows. The Northern low will move across the Great Lakes and then over the Northeast merging with the Southern low. The Southern lows track will take it across Florida and then towards the Northeast. When these two storms merge they will form one powerful storm system with large impacts in the form of very heavy snows and blizzard conditions. The solid green line is our forecasted rainfall impact region, with most places seeing up to one inch of rain with some locally heavier amounts possible. The light blue line is our outline for the snowfall area. The dark blue line is the forecasted area that will see heavy snow with moderate accumulations. The purple shaded area inside the blue lines will see the most significant snow totals; some places could be measuring the snow in feet. The pink lined area will be the place to watch for the development of freezing rain and snow along with rain mixing together; some minor accumulations may be possible.
