DAYS 1-5 (JUNE 17-21)

We have another nice day in store for today but there will be some varying amounts of high and mid level cloud cover to limit the sun. A disturbance approaches from the west and while it can trigger a few showers and thunderstorms to our west later today that activity is expected to dissipate before arriving. Overnight light rain approaches as a warm front begins its trek across the region, one that will produce additional showers and perhaps some embedded thunder in our area during Thursday morning. We enter the warm sector of low pressure passing to our north Thursday afternoon, and a trough and cold front will then move through the region, being focus points for showers and thunderstorms. While a lack of sun and marginal instability are negative factors, there is some potential for a few strong storms with the help of a couple other positive factors, including decent wind shear, which could allow any established storms to become super cells and rotate. While this probability is not extreme, it’s enough that we should pay close attention until the storm threat passes and ends in the evening. So, be weather-aware Thursday, just in case. Behind this what is a three day weekend for many (Friday through Sunday) looks quite nice. We will see some breezy conditions at times between low pressure to our northeast and high pressure building from the Ohio Valley to the Mid Atlantic especially Friday and Saturday. Both of those days will also see some passing fair weather clouds, but I strongly suspect any pop-up showers will be confined to the mountains to our north. Sunday, we’ll see some high clouds fanning across the sky in advance of our next wet weather threat, but that will hold off easily for a dry day and evening to finish the weekend! Heat and humidity will be absent during this stretch as well, making it quite pleasant for outdoor activities. We welcome summer with the occurrence of the solstice at 4:24 a.m. on Sunday.
