PM Update: Dense fog tonight, possible showers; partial clearing, breezy on Tuesday

* Dense fog advisory through 6 a.m. *

It’s been a murky day with an abundance of clouds and fog. Northeast Maryland remains pretty socked in and fog may re-develop elsewhere before the front comes in and mixes the air up late tonight. Today’s highs near 50 and into the low 50s remain warmer than normal for this time of year, a trend set to continue for at least a while longer. 

Through Tonight: Fog is likely, rain is questionable. Showers to the west will try to work this way, but it appears they’ll largely end up skirting the area. Still, our shower odds go up a bit this evening into the early overnight, with about a 40% chance area wide, dwindling again late. Don’t expect much rain anywhere. Lows are mild, and temperatures only make the mid-and-upper 40s (about 43-48).

Tomorrow: After the front passes late night or early morning, a cooler air mass doesn’t push in too strongly. When combined with winds compressing air off the mountains, we should end up with “warm” highs in the mid-and-upper 50s. Those winds are gusty too, sustained around 15-20 mph in the afternoon, so there will be a bit of a wind chill factor. Any morning sun probably leads to further clouds as the day wears on, and a shower or two can’t be ruled out thanks to a bit of energy aloft passing by during the day.

West Coast: Quite often when it’s warmer than usual around here, the West Coast is dealing with the opposite -- today is no different. Blizzard conditions have been impacting mountainous areas of the Pacific Northwest, where Snoqualmie pass was closed due to the conditions. Southern California is also spending another day with cool and rainy weather. TWC has named this storm, and it’s expected to cause trouble through the country over coming days.
