Monday October 23, 2017

Warm weather for two more days, then we get into a real chilly pattern that will want to stay this time. Yes, this faux fall is about to end. The unseasonably warm air now has added moisture with it. With longer nights it is inevitable to chill down and super-saturate the air, which has led to some thick fog in spot. The morning map here shows the lowest visibility under 1 mile in red. That appears to be along the Maryland/Pennsylvania border, around Washington in the Potomac Valley, and along the bay-side of the lower Eastern Shore. There is some fog around the Baltimore beltway, but not as bad as some commuters will experience on the way in. All will improve between by 9 AM and give us another warm day.

The cold front to our west has some moderate rain with it and may bring showers this evening. It will pass through tonight and Tuesday morning. Behind that will filter in colder air that we will feel  if for the rest of the week. Reinforcing shots of colder air will bring snow showers to the mountains. Halloween will be chilly and November will start feeling like its supposed to.

Rain Timeline

Most of our rain will fall between midnight tonight and sunrise Tuesday. The highs on Tuesday may be at midnight, it will still be mild in the afternoon. The colder air often lags half a day behind the cold front. We will feel it by Wednesday.


One week from today it will be much colder! The jet stream will send a deep trough in to the eastern US and temperatures  will be well below normal. This pattern looks to sustain itself for the next week or two at least.


Snow Showers and Flurries

Getting the flakes to fly east of the mountains may be a stretch as the GFS model shows here. But I see a burst of snow in western Maryland and this high country of West Virginia and western Virginia to start next week.

Blue is colder than normal and there is plenty that locks into the eastern US
