Friday January 12 2018

You may already know some of the weather just by hear the wind and rain banging against your window. Moderate rain had moved in overnight, but the fog may be the added element to slow your commute down even more this morning. There will be periods of moderate rain today, but also a few hours at a time that are dry. Those are likely in the afternoon and evening.

Tonight is when the weather gets more dramatic. Heavier rain might have some rumbles of thunder, then the cold front swings through. Temperature at midnight could be in the lower 60s, but near or below freezing when you wake up on Saturday morning… especially near and north of Baltimore. That is where this may end with ice and snow.  A Winter Weather Advisory has been issued for southern PA, but the northern Maryland counties might get in on some action… Then we all set up for a cold weekend.

This temperature contrast is the really for the strong winds feeding into the storm

Friday Evening

Periods of rain sounds cliche, but there will be moderate rain this morning and again tonight. But there will be a few hours at a time with no rain. We should get these dry hours durning the afternoon and evening.

The track of Low Pressure into southern PA will help to bring the cold air in behind it and some wintry mix Saturday morning.

Temperature Outlook

Reminder that the high temperature for Saturday will be at midnight, Most of the day will remain below freezing, and turn colder Sunday/Monday.

Snow Next Week?

The quick moving system expect on Tuesday does not have a lot of moisture with it. At this time I would suggest a period of light snow during the day
