Late Night Model Runs on Winter Storm






If I had to make any change tonight, it would be to shift the heaviest snow accumulation to the east. However, the initialization reveals that the storm track may actually be slightly west of both 00z Guidance low pressure positions. Therefore, I will not make any changes until tomorrow morning if necessary.

Temperatures tonight have dropped below freezing in many areas. Therefore, any light precipitation, should it develop, will be sleet or freezing rain until about 10 or 11 in the morning. After that, we may see any freezing rain or drizzle changeover to plain rain in Central and Southern New Jersey.

Again, the snow line begins to move east around or just after rush hour....doing so quickly...and that is when the precipitation will become heavy.
