Warmer Today but What About the Weekend?

Wednesday 9 a.m.

The offshore storm that kept it gray and chilly along and near the Middle and North Atlantic coastal areas yesterday is continuing to move away... and it is turning warmer today. A cold front that brought more rain to waterlogged sections of the Great Lakes yesterday and last night (many dozens of roads still closed because of flooding in Illinois) will trigger thunderstorms as it crosses the Appalachians this afternoon. I can't be sure about this, but those storms may weaken as they approach the I95 corridor.

With the cold front offshore tomorrow, the afternoon will be cooler than today over much of the Northeast. The coolness will linger into Friday. After that, however, a warming trend is likely, and fine spring weather should hold well into next week. Computer models suggest a return to wet conditions after that. Here is my video from this morning.

A meteogram provides a way to show a forecast on a graph. I know the numbers on the graph are miniscule at this scale but two things stand out: (1) a warmup this weekend and early next week (the top graph) and (2) the overall dryness for the weekend and early next week. This graph is for Philadelphia. On the AccuWeather.com professional site, you can plot one of these for any point you want.
