I think my last couple posts have elaborated in detail on the dynamics of this system including my concerns about accumulations, so I will not rehash all that here. We are currently under a Winter Storm Watch, but don't be surprised to see the watch in central MD turn to a warning. So, let's get to the good stuff...
TIMING: Late Tuesday into late Wednesday, although if the storm stalls it could last through Thursday morning.
PRECIP TYPE: Rain to start than changing over to snow. Those in S MD will see a longer period of rain, but it will change to snow. For S MD the change may not happen until later Wednesday afternoon, while those in central MD could see the change earlier Wednesday.
ACCUMULATIONS: There will be a fine line between those who get a lot of snow and those who don't. Generally speaking, those around DC into Baltimore then N and W should see more while those in S MD and along the Bay should see a bit less. Generally, central MD toward the PA border should see around 6-10" while those in S MD around 4-8".
THREATS: The snow will be wet and heavy, therefore there is the potential for power outages and tree damage.
CONCERNS: The accumulations will drastically change up or down depending on the exact path of the Low; the timing between the rain / snow change over; the surface temperatures. My forecast is taking these conditions into account, but until we know how quickly this changes to all snow will I know better if my amounts are too high or low.
I will have another update on Tuesday as needed. Follow me daily on Twitter (@wxmanmd) for weather/storm updates and tidbits.
Comments will take a few seconds to appear.
