Quiet in the short term

An arctic airmass is moving towards the regions, however, the cold will not assist in any snow events. The first threat that had been watched was low pressure moving out of the Gulf of Mexico today, however that storm is expected to move well south of the region, and even south enough to keep Virginia dry. Parts of Cape Cod masy experience the outer edges of the storm later tonight but with only trace to 1" accumulations.

The next storm that needs to be watched is on Tuesday. A short wave will move east-southeast from Canada and across the Great Lakes into northern New England on Tuesday, bringing light precipitation (generall .1 to .3" water equivalent). Ptype should not be an issue anywhere west of I95. East of I95, there could be some rain mixing in, depending on the track of the low. The main factor that needs to be watched is enhanced precipitation along the front as models have been hinting at secondary development. Currently, it is progged too far northeast to have any effect on the area, but does bring the cape the potential for over .5" water equivalent. For an early forecast, right now it looks like 1" to 3" possible.

You need a larger threat to watch? Well, recently a very intense coastal storm has shown up on the 204hr Euro and the GGEM is showing a similar set up at 228hrs. This is progged for around Monday 1/28, but remember that this is in the long term, and has only shown up twice now. At the very least it will be something nice to follow on the models (if it stays) during this period of quiet weather.
