A severe thunderstorm watch has been issued until midnight for northern and western Virginia. Widely scattered storms will turn more numerous this evening. Any thunderstorm that develops will produce extremely heavy rainfall and prolific lightning. Isolated storms may become severe with strong wind gusts and large hail. The threat for tornadoes is very low but cannot be ruled out, especially over the Northern Neck and Middle Peninsula.
High temperatures will reach the low to mid 90s this afternoon with a heat index near or above 100° in many locations. A heat advisory is in effect for the metro plus southern and eastern Virginia, where the heat index will hit or break 105°.
Friday will be a few degrees cooler, but highs will still be near or above 90° for much of central Virginia with a heat index near 100°. A few scattered storms are possible in the afternoon and evening, and isolated storms could be strong.
The weekend will still be very humid with highs in the upper 80s to around 90°. Clusters of scattered storms will be possible both days, but there will be many dry hours over the weekend.
Highs should stay below 90° for the first half of next week, but more heat will return Thursday into next weekend.
