Good day everyone!
Time for round 2 of winter weather.
Analysis this afternoon of the current GFS and NAM runs indicate low pressure developing over the W. TN Valley region, and will track NNE over extreme western PA. and NY over the next 24 hours. As the low intensifies, Mariners from the Mid Atlantic area, northward can expect seas offshore, from 69W to 63W, to run between 14-18 ft. Along the New England coast, waves could run 6-8 ft along the coast with winds approaching the 30 knot range…for the offshore area, winds of 30-35 knots will most likely occur, as the low intensifies. On the backside of this low, more snow on the way, changing to frozen precipitation later. Based on model analysis, I am expecting the heaviest accumulations over the next 84-96 hours to occur over Indiana, SW into Missouri. Looking also for blowing Lake Effects Snow over portions of Indiana, Ohio, and western portions of PA and NY.
With this system, comes a moderate shot of Arctic air. Forecast lows for Tuesday morning indicate below freezing temperatures as far south as most of Texas and Louisiana, with teens forecast for minimum temperatures, as well as a good majority of the Florida Panhandle. I am expecting possible freezing temperatures all the way down to my area (Tampa Bay), with lows ranging from 30 – 32F around the TPA and MacDill area – 35F in some areas closer toward the coast. Residents from this area, north, should monitor this possibility closely, as to protect tender plants. PLEASE, remember to bring any pets indoors…they get cold just as we do.
There is a good possibility I may not be on tomorrow, as my car needs to go back in the shop. So, as always, ALL graphics are linked to their websites in order to provide up to date information…just click and you’re there.
Have a blessed evening, and stay warm!
