Tuesday April 17 2018

It’s tax day and you may want a refund on the weather. After two days in the 80s, the cold air has fought back and will try to dominate for much of the rest of the month. Today, we continue with strong winds that have developed Lake Effect Snow Showers. Garrett County will be showing off with a few inches of snow, but locally some flakes may fly this afternoon in the form of flurries or a stray snow showers, especially on the north side.  As the winds settle down and the sky clears tonight, a Freeze Watch is in place west of I-95.  Then we at least get back to the 60s tomorrow. See the outlook for the rest of the month as we remain on the below normal side.

Morning Temperatures


This Afternoon

Strong winds will gust up to 25 mph and keep us partly to mostly cloudy. There will be snow adding up to 3 inches in Garrett County. After noon, showers will cross the mountains. There will be waves of snow or rain showers across northern Maryland and southern PA. So flakes may fly around York and maybe Westminster.  Some sprinkles or flurries not showing up there could pass through central Maryland between 2 PM and 5 PM.

High Temperatures


Freeze Watch/Warning

The normally colder areas inland will dip down into 20s tonight. Southern PA is not included on this map, but will be part of the freeze.  The dark blue shaded areas are where the warning guarantees the coldest temps by tomorrow morning.

Low Temperatures


Looking Ahead

The jet stream wil be dominated by a cooler flow. While we may modify near normal next week, overall the rest of April is expected to remain on the cooler side.  The temperatures will modify a little, but still remain a few degrees below where we should be to end the month.
