WEATHER BLOG: Wednesday
Today, some clouds will linger for a while this morning, especially in southeastern Pennsylvania, South Jersey, Maryland and Delaware.
There can also be a few high, thin clouds farther north, too. However, the trend will be for clearing to allow for a good deal of sunshine today, especially from mid-morning on. High pressure, which is currently spreading out across the eastern Great Lakes Region and southeastern Canada, will be driving a 'wedge' of drier air along the east-facing slopes of the Appalachians. Therefore, it'll turn out mostly sunny this afternoon with most temperatures reaching the 60s.
Under a relatively clear sky tonight, it will become very chilly in most areas outside of the larger cities and towns. The temperature will drop into the 30s in these normally colder spots, while most urban areas will wind up in either the low or mid 40s. Tomorrow will be another nice day as the ridge of high pressure begins to drift to the east.
Eventually, the core of the high pressure system will consolidate out over the open waters of the ocean tomorrow night and early Friday. That should begin 'opening the door for' some potential trouble. Actually, it doesn't really look like we'll be encountering any thorough soaking on Thursday night or Friday. But, as a weak impulse of low pressure slides out of the Great Lakes and into the Northeast, an area of widely-separated showers located in western and central Pennsylvania on Thursday night should drift to the coastal plain / I-95 corridor on Friday.
This area of showers will become more and more 'diffuse' as the day wears on, so we really do not want to give anybody the impression that the Friday afternoon commute, or the 'start of the weekend' will be dull and soggy. Friday's temperatures should be mostly in the 60s, and Saturday does have the potential to be even warmer.
