Pinpoint Weather: Heat and humidity remain, along with the daily chance for strong storms

Weather Blog

The overall pattern is not going to change until we get into the weekend and rain is likely for the next several days. The chance for strong to severe storms each afternoon until then is high. This evening a Severe Thunderstorm Watch is in effect until 9pm tonight.

The SPC has placed our Piedmont locations under the Slight Risk category for severe storms at the heat and humidity are combining for a rather robust day.

 The reason for the persistence is an area of high pressure over the SW Atlantic, basically, a seasonal feature often called the Bermuda High, will not deviate from its position very much this week.

The high along with a flow of air from the west will maintain our persistent pattern of precipitation each afternoon. The storms come in from the west-northwest early in the day, migrate toward the Piedmont and intensify in the very hot air introduced by the high.  The storms will be strong enough to generate very gusty winds and some small hail, so secure the trash bins this week as they may be pushed about by the stormy weather.

High temperatures will also be very hot ahead of the storms. Yesterday was the hottest day of the year in Roanoke as we reached 96 at the airport. Other reporting stations were in the middle 90s as well. Expect to see more of the same heading forward through the week.  Records are expected to be in jeopardy Thursday as the record highs are a bit lower on the 12th. 

Thursday and Friday look to be similar to Wednesday with the severity of the storms being the only variable. The scattered intensity of the storms will be present each day, so depending on where you are, you may need to keep a watchful eye to the sky and take cover for a while.

Saturday will also be hot, but a cold front looks to arrive late in the day. More widespread storms could be in the cards Saturday afternoon or evening as the front approaches.  Sunday will still be rainy off and on, but highs will only be in the low 80s.

Next week we keep an eye on Fred as there is a chance that the remnants of the Tropical Cyclone will be moving over the Commonwealth by Tuesday or Wednesday or even as late as Thursday.  That will be monitored.
