Heavy rain is affecting eastern New England today, but farther southwest from New York City to Washington, D.C., drier air has arrived. Temperatures dropped to the 50s across the Great Lakes and Ohio Valley last night, with some spots dropping to the 40s. The cooling will be less pronounced along the East coast. This video talks about weather prospects from now through the weekend.
July is national blueberry month.
But why not talk about other fruits or even vegetables? In the weather business, every month represents a time when we have to break through any salad bars to understanding the weather. After all, even if I might peppercorn in my report, I fully realize that in the morning, you're all russian dressing, orange you?
I realize there are some of you who may not carrot all, but how could we justify our celeries if we didn't toss a forecast your way? For the kiwi say that the airmass that peared back the temperature in the Midwest will not be as cool when it reaches the East Coast.
As we comment on what will be currant Friday through the weekend in the Middle Atlantic area, we see a number of possible outcomes, Lettuce say it will be parsley sunny and that any showers may not be cucumbersome. At this point, however, we cannot produce any specific time for rain because the uncertainties make that kind of prediction for water chestnut possible.
Meanwhile, it is cool and crisp around the Grape Lakes. For many, the lower humidity will appeal. In the Southeast, sunshine, heat and humidity will be the top bananas. In our field, we always cultivate new ideas and provide an updated crop of reports. Kumkwat may, we want your visits to the garden of AccuWeather.com to be fruitful. As for me, avocado go now!
This pressure map shows the strong circulation around the storm that brought all the warm air northward... and which will force colder air eastward next.
Looking at next week, the GFS ensemble spaghetti plot of upper air winds shows how much agreement there is among members of the ensemble (same model running multiple times using slightly different starting assumptions). The maps are from next Tuesday, Nov. 25, and Thanksgiving Day, Nov. 27. There is good agreement on the first map, but a lot of spread two days later.
The location of lake-effect snow bands is tightly controlled by geography, topography and wind. From this pressure analysis, we see why the wind favored heavy snow staying south of the hardest hit Buffalo snow belts earlier today.
If this timing works out, there would be good travel weather for the Northeast Corridor on Wednesday while snow showers cross the Great Lakes and reach the northern and central Appalachians.
This map from one of my tweets yesterday (accuElliot) showed the wind direction most favorable for heavy lake-effect snow in and near Buffalo. Just a minute change in direction greatly affects the location of the heaviest snow, almost as if you were operating a fire hose. The snow is so deep (more than 4 feet in spots and deepening) that officials were considering the use of high lift equipment to extract vehicles.
It suggests rain in the I-95 corridor and snow from the mountains of West Virginia and Pennsylvania to southwestern Maine. Other models and ensemble versions will be examined this weekend as we narrow down the uncertainties associated with this fast-moving storm. Whatever the form of precipitation, you can count on another shot of cold air behind it. Lake-effect snow will be common as well.
