Baltimore, MD - It's hard to believe last St Patrick's day weekend temperatures were hitting the middle 60's followed by a few days in the 80s ! Well, this year will NOT be the same case as we are expected an unsettled weekend kicking things off with the potential for a rain snow mixture outside the city.
An area of low pressure will form over the Ohio valley this evening and push east by tomorrow morning. As cold air sinks south and precipitation runs into it, a burst of snow is expected before changing over to all-rain during the mid morning and afternoon hours on Saturday.
There could be very minor accumulations over the MD/PA line but most of that will be on grassy surfaces and cold areas.
A rain snow mixture expected most of the day over Carroll and Frederick counties. No accumulations expected aside from far western Maryland.
Here is a look at Future Trend to map out your Saturday.
Saturday morning Snow rain mix moves into the city. Light snow over Carroll, Baltimore, and Frederick counties.
Saturday Lunchtime - Rain in the city . Rain and snow mixture over the MD/PA line
Saturday late afternoon/evening. Rain for the city south and east. Wet rain snow mixture along the MD/PA line.
A slushy coating to in some cases near an Inch could be found west of I 83 and over Carroll and Frederick county seeing as temperatures will start out near freezing when the precipitation moves in.

All-time record high temperatures were set at several location in south central Alaska Monday afternoon.
A potent area of low pressure will move along this rim and drop down the front side bringing a round of severe weather to Maryland Wednesday evening/night through Thursday afternoon (timing is still in question).
As the moisture from this tropical low moves north it will interact with a trough out to the west. This will increase Maryland's rain chances late Thursday into early Saturday morning.
Meteorologists with the National Weather Service and researchers from the University of Oklahoma continue to investigate the May 31st El Reno tornado that hit just west of Oklahoma City.
No big shocker here. Oklahoma shares the top of the list of states with the most tornadoes rated either F5 or EF5 since 1950.
