Hello, this winter storm Q that's heading towards the Midwest, bullseye looks like Salina, KS.

As this low spins towards a drier high pressured air mass, it will slow down and weaken. It turns out that another wave of low pressure will start spinning around New Orleans, LA and head northeast potentially becoming a full blown nor'easter.

This situation is still days away but the potential for at least 3 inches of snow or more for Philly, NYC and Boston looks like the bullseye again. The high pressure over the Halifax, Canada will be much weaker compared to midweek therefore, it won't draw the very cold air we would want for  this storm to start as snow and remain all snow. The good news is the heaviest precipitation that should hit the ground will begin after 5PM ET on Saturday Feb 23rd 2013, and not be (virga-precipitation that falls from the clouds, but it is to dry at the surface to hit the ground). It looks like the nao may plunge into the negative area, resulting this area of low pressure to ride up the coast.

This is all good news. The highs should be in the upper 30s to low 40s on Saturday but the only bad thing is we don't have a solid arctic air high pressure, but I do believe it will be colder than last Wednesdays storm where the highs got up to upper 40s and the storm made its own cold air for it to drop a few inches where it was hit by heavy precipitation. I do believe this storm will be much stronger and also the fact that it will ride up the coast, it will certainly not be moisture starved.

I am not going to give any snow accumulations forecast but the potential is there for a major snowstorm for at least 3 inches of snow if everything pans out. Look for the storm to move out Sunday morning. I will be keeping a close eye on this storm as it develops and I will keep you posted.
