DAYS 1-5 (JUNE 14-18)
The heat and humidity will tick-up over yesterday a little, but the latter will not be to the level of what we experienced Thursday and Friday of this week, and a ventilating breeze will also make it more tolerable outside today. We stay rain-free through the daylight hours and into the evening, with shower and thunderstorm chances increasing late evening into overnight from west to east with a passing cold front. This front will move offshore early Monday with a lingering shower possible in the eastern coastal plain early. Otherwise look for a cooler, dry day with a breeze and a sun / cloud mix. High pressure slides south of the region with fair and seasonably warm weather Tuesday, though humidity levels remain fairly low. Clouds increase Wednesday ahead of an approaching warm front as low pressure heads into the Great Lakes, but I do expect our day to be rain-free, seasonably warm, and becoming moderately humid. Thursday’s weather is the most interesting and potentially volatile of this 5-day period as we will have a vigorous surface moving from the Great Lakes to southeastern Canada, and a vigorous upper trough moving into our region. With the arrival of warm, humid, unstable air, the stage is set for showers and thunderstorms, with the potential for some severe weather. With it being “day 5”, obviously it’s not a highest confidence forecast, but the signs are there already and I feel it’s important to note it now, and obviously update the outlook as we get closer to that day.
