Muggier, warmer weather returns this week
Although the weekend may be coming to a close, too quickly as it always seems to be, there is some good news in the forecast for the upcoming week. A building ridge (we haven’t heard that statement in a while) will bring increasing mid level temperatures and rising heights aloft. The presence of high latitude blocking and a persistent ridge out west have, for the most part this summer, inhibited the development of any ridging in the Northeast United States. But, as is the case with all patterns, there are exceptions — and eventually changes. For this week, we’ll see the return of a southwesterly winds and warmer temperatures as well as increasing humidity.
High temperatures by the middle of the week could flirt with 90 degrees in the urban corridor of Philadelphia to New York City. This will be especially true on Wednesday, when mid level temperatures will peak around 18 C, typically supportive of temperatures over 90 degrees. The warm weather won’t last forever, but while it’s around during the early to middle part of this coming week it will certainly feel more like summer. Or more like August should feel, compared to the Autumn-like air we’ve become accustomed to over the last week or two.
