Saturday Morning Update
This developing weather situation is very complex. This morning, there is dense fog, and an advisory has been extended across the region. The storm will bring rain on Sunday, which will become heavy in the afternoon and evening. The Ravens Game will be soggy and windy! A Flood Watch is in place for possibly over 2 inches of rain.
The Storm will slow down, allowing colder air to catch up. That will bring in a change to slushy snow on Monday morning. Temps may remain above freezing at the ground, but some stickage and impact on the morning commute inland is possible.
Under 1 mile visibility in spots. The Advisory lasts until 10 AM
The developing storm will take shape today and expand our way on Sunday. This is complex with many elements, and it will slow down with waves of Low Pressure along the cold front. That will allow the colder air from the Northern Plains to catch up Sunday night and bring us some local snow.
With more sunshine and a shift of winds, we get back into the 50s.
Closer look and more details below….
Sunrise at 7:14 AM
Sunset at 4:44 PM
Normal Low in Baltimore: 31ºF
Record 4ºF in 1876
Normal High in Baltimore: 49ºF
Record 73ºF 1966
Rain will become steady and heavy. The front will have waves of Low Pressure that will slow it down and enhance the precipitation, allowing the colder air to catch up to the final wave on Monday morning.
A transition to sleet and snow is expected Sunday night into Monday morning.
It will be warmer into the lower 60s.
Moderate to heavy rain will be falling during the game.
Winds FROM the south may gust 30 to 40 mph.
Heavy rain shifts east while a mix may begin to take over between Fredrick and Hagerstown.
There will be a mix of sleet and end with snow.
The clouds will be cold, but the ground will be above freezing. This makes stickage complicated, and will more likely just be on the grass. Inland areas may get more slush, and some roads could be comprised in Northern Baltimore, Carroll, Frederick Counties and Southern PA.
This tells the story: Remaining above freezing.
HOWEVER: There can be heavy snow rates that briefly overtake the ground for slush on the roads.
It is IMPORTANT to note that this product shows what may fall, but not all will stick.
There may be a coating of 1 inch on the grass in central Maryland and even south/east to Delmarva.
Higher chance for stickage on grass and even some roads for the inland suburbs.
The pattern of a weekend storm will be followed by colder air for much of next week.

I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work when I need it and have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm.
