A Winter Storm Warning was expanded to include all of Harford County. A Winter Weather Advisory continues in central Maryland where this snow is over achieving. However flooding already an issue on the Chesapeake Bay (green). Water may run 2 to 3 feet above average thanks to the winds around the storm.

Today is starting with an over achiever around Baltimore city and northeastern Maryland, while it has been a bust in others. While many schools have delayed or closed in central Maryland, southern Pennsylvania has missed out on the first part of this event with almost nothing on the ground there yet. The second part is developing this morning as expected, but will be less intense and have to battle the sun angle.

Most roads are wet and will stay wet. There will be some slush, especially on elevated roads/bridges. But the main accumulation will be on the grass. However, moderate snow can reduce visibility making driving difficult.

Phasing is occurring now. This is the time we watch the storm expand in coverage and intensity but may be a little late and lose to the sun.

Note that due to mild temperatures, snow will be heavy and wet. But when it eases up and is lighter, it may mix or turn to rain

Additional Snow Possible Today

Here is my adjusted snow map for what may fall today. See the new radar simulation slider below

Note that snow during the day will likely stick on the grass but roads will be wet

Temperatures

Noon Today: Snow will be falling while temps are above freezing AND battle the March sun angle. That means more snow will melt and compact
