Warmup Awaits For End Of Week

With a reinforced shot of cool air working in for the next few days, some may be thinking the days of 80 degree weather are past us.

Not yet. The yin and yang of September suggests another shot of warmer air will work in later this week, with the potential for 80 degree days in the forecast for Friday and perhaps Saturday in advance of a storm system that will cross the country.

High pressure will sprawl over the East for the next several days, providing beautiful weather for the balance of the work week. Temperatures, as the high slips south through the Northeast and gradually off of the East Coast, gradually trend higher each afternoon after tomorrow. Friday will likely provide our warmest day of the week and warmest since the near 90 flirtation last Thursday afternoon.  While we won't get anywhere close to the 90's, 80 or low 80's isn't out of the question by Friday afternoon along I-95.  If we don't hit 80, we will get very close to it.

Since we will have a southwesterly flow of air in the atmosphere, humidity will be on the increase as well as a frontal boundary approaches from the west.  As of now, the front is projected to move through the region on Saturday afternoon and evening -- modeling varies a bit (which is not surprising this far out) regarding timing specifics but the GFS is the slower and more consistent on timing with the front at this point.  Showers and storms accompany the front, with the possibility of some soaking showers in some spots as the front slides through.

As of now, it doesn't appear the front will impact the region for the whole weekend...just part of Saturday in the region.  Sunday, from this vantage point, looks as if it will be a nicer day with reinforcing dry air moving back in.
