Interesting Week Ahead

It's time for the January thaw with impressive temperatures in the middle 40s to begin this week. Take a look at this model for today. Temperatures are increasing over the next 36 hours. This map showers temperatures of +8 C or 46 F! And that's at 850 mb. Even more impressive is the model for 12z or 7am Tuesday. Temperatures are once again warm, but take a look at this multi-contoured low. Why does it mean anything. Well first of all it's a major pressure change and secondly with the isobars tightly packed it shows a strong pressure gradient. So its also going to be breezy. Temperatures will take a big fall after this system moves through Tuesday night from the 40s into the teens. Here's what Wednesday morning looks like
highs will be in the twenties Wednesday.

NWS has a casual mention of a possible snowstorm with accumulations on Thursday night to Friday. What do you think?

Cathy,
Right now, as you probably know by reading this blog that the GFS is not my model of choice. Mostly because it's inconsistent. That said the ECMWF is bringing the low north and cutting it off to the west. So for right now I am saying I don't think so. But I'll keep up on it with further model runs.
