Fall is the time of year when we often experience large temperature swings over the span of a few days, and this week is no exception.
Fall is the time of year when we often experience large temperature swings throughout a work week, and this week is no exception. As we transition to the upcoming cooler temperatures, rain is likely for the middle of the week.
The stage is set for two systems to converge over the Washington area causing active weather for the middle of the week. A sharp dip in the jet stream is anticipated, which will add to the dynamics in the atmosphere. Meanwhile, a low pressure system will venture northward from Florida while another heads east from the Great Plains. These two systems will essentially converge and become one larger system overhead leading to areas of rain on Wednesday.
- A shifting weather pattern causing noticeable changes
Rainfall looks likely on Wednesday, but I'm not expecting a continuous, all day rainfall. Instead, off & on showers are anticipated from late Tuesday night through Wednesday evening. Behind the rainfall, the cooler air will spill into the Washington area with gusty winds on Thursday. Being a transitional day, temperatures should continually drop throughout the day on Thursday, so our actual high temperature is expected come around midnight. The cooler air will be in place by Friday with highs likely in the upper 50s/near 60 on Friday and remaining Fall-like into the weekend (60-65). Here's the predicted rainfall from the Hydrometeorological Prediction Center:
