First Heat Wave of the Summer
The first heat wave of the year is set to begin this week as highs climb into the 90s. The definition of a heat wave is at least three consecutive days of 90+ degree temperatures.
The current forecast calls for a strengthening ridge of high pressure to move across the Mid-Atlantic and Southeast states over the next few days. This will allow plenty of sunshine to take over and temperatures to rise. Highs are expected to approach 90° on Wednesday with lower humidity, but by Thursday, highs will likely climb into the low 90s with higher humidity.
Friday and Saturday look to be the hottest and most humid days with highs reaching the low to mid 90s with heat index values in the mid to upper 90s. A few storms are possible late in the day Saturday as another cold front approaches, which may bring some relief by Sunday. Highs will still be near 90 on Sunday with partly to mostly sunny skies and a chance for a few storms late.
Back in May, Salisbury hit 90° three times, while so far this month we’ve only recorded one day at 90°. But that is about to change as we play catch up over the next several days. Luckily this won’t be too dangerous of a heat wave, as heat index values likely stay below advisory criteria. Stay cool!
Below is the current 7 day forecast and the current 5 day heat index forecast.
