WEATHER BLOG: Sunday

The oppressive heat and humidity that we experienced yesterday will continue into the day today, with today actually being the most oppressive day of the summer thus far. As an upper level ridge strengthens across the central US, bulging toward the east, oppressively humid and hot air will filter into the region. 850mb temperatures will surpass 20°C, leading to high temperatures in the middle to perhaps upper 90s across the region today. Dew points region wide will be in the lower to middle 70's, leading to RealFeel temperatures near 110.

During the afternoon, a cold front will move through the Great Lakes with a few spotty storms possible north and west of the city during the afternoon. The city looks dry during the afternoon, as does much of the viewing area. Strong thunderstorms will impact western NY and PA during the afternoon, moving slowly south and eastward during the evening. As this occurs, there may be some gusty thunderstorms across our viewing area during the evening. While they will tend to weaken after sunset, some of these thunderstorms may contain gusty winds and heavy rain during the evening and into the overnight as the front approaches.

The timing of the cold front looks a bit faster than it did yesterday, moving through early Monday morning along with those storms. With the passage of the front, dew points will not lower much. The airmass is still hot behind the front as well, so temperatures will likely reach the lower to middle 90s. The front will stall very close to the Mason-Dixon Line, and both the 0z GFS and 0z GGEM have some thunderstorm activity during the afternoon, so it has been included in the forecast.

Dew points will remain high Tuesday as the front stalls near the Mason-Dixon Line. Tuesday looks to be in the upper 80s- very seasonable for this time of year. A secondary front will approach Tuesday afternoon, but without much instability, storm coverage looks limited, though there could be some storms around.

The middle and end of the week looks rather quiet and cooler, with temperatures in the middle 80s. Precip chances after Tuesday look low.
