Stratospheric temperatures continue to rise steadily this morning with much of the atmospheric layer from 1 MB to 70 MB now averaging above normal. The warming at 1 M is starting to slow some as the temperatures approach record highs, however model guidance from the ECMWF suggest another period of warming is on [...]

My thoughts this evening on the storm for Friday night through Sunday morning has not changed much. The overall development of the storm will depend on the development of the Polar Vortex and the interaction of the Arctic cold front with the Sub Tropical disturbance.

Another run and more indecision on the model guidance on what to expect for the period of Sunday night through Monday. What disturbance is causing these issues? I have found the culprit and this feature is not going to be handled very well until late in the week at the earliest!

I’ve gotten a lot of emails through the day about pattern changes, storm questions, and pretty much everything in between. First, I’ll answer one question I can share with everyone. Yes, I really am a Mets fan. So, lets get to the rest of the questions.

The strong Polar disturbance that is more developed than guidance suggested a few days ago is an important clue and reminder for the forecast later this week. For now, that disturbance represents another push of a Polar/Arctic air mass after Tuesday afternoon. The key to the forecast over the next several days is the [...]
