A round of thunderstorms with heavy rain is likely during the mid afternoon hours tomorrow. Warm and very humid temperatures give way to cooler and less humid weather by Sunday. Temperatures moderate again towards the middle of next week when another shower and thunderstorm threat returns Wednesday.
A long wave trough advects into the region tomorrow and Sunday. At the surface, a cold front passage will trigger shower and thunderstorm development across the state tomorrow. With dewpoints surging into the low 70’s out ahead of the front and lifted index values between -3 and -4, some of these storms will become strong, and with precipitable water approaching 2″ heavy downpours will be likely with any convection. While the timing remains a bit challenging it appears the most likely time window for these storms would be between 2 and 8 pm.
The weather dries out significantly by Sunday with high pressure moving in and sticking around. Another cold front makes an approach Wednesday, but I’m not seeing much more than an isolated shower threat with it for now.
