It’s always nice to get a break from the 80+ degree warmth, and with the help of the rain that moved in behind the front we did that yesterday. Our high of 76 was first day below 80 since 78 on June 19th. However, the heat will build in the coming days. With the humidity and heat, we are probably going to see the combination make it feel like it is close to 100 degrees at times, especially Tuesday, Wednesday and Thursday. During the peak of the heat, it looks like this stretch will bring temperatures a little higher than the heat that built on and for a few days after the Fourth of July.
The upper level trough, that evolved into an upper level low, coming in behind the front helped force moisture back up and over the front and that is what caused our rain yesterday afternoon and last night. The upper level low is centered back in eastern Kentucky right now and will be backing westward as upper level high pressure builds and reestablishes itself by tomorrow across the Northeast and mid-Atlantic and temperatures will be on the rise. The humidity, which has returned after a brief lowering behind the front, will be a factor the through the work week. The center of the dome of high pressure will actually move westward into the Ohio Valley during the early to middle part of next week, but is vast expanse will keep us with the heat and generally dry with more sunshine than clouds. One thing to note about the humidity Tuesday, Wednesday and Thursday, is that the position of the dome of high pressure keeps us more or less in a surface flow with some westerly component. That combined with the mixing of drier air above the surface may see dew points lower some at times during the afternoons, before the dew points rise again during the nights. Either way you slice, a hot, steamy pattern.
