High heat and humidity will gradually come to an end later this week as a slow moving cold front approaches from the north. The front is expected to stall over our region, bringing multiple rounds of thunderstorms to our area over the next several days.
There's no relief from the heat and humidity in the short term. We're expecting another hot day tomorrow, with high temperatures near 90. The humidity is expected to be really high again tomorrow, with the heat index expected to be in the mid 90s once again. A heat advisory continues tomorrow for the Mohawk Valley.
Thunderstorms are expected to develop and produce locally heavy rain and frequent thunder and lightning as we head into tomorrow afternoon. The setup looks similar to what happened today, with scattered storms affecting parts but not all of the region. The storms that rolled through today did produce some localized flooding and scattered power outages. A lightning strike in the town of Trenton may have been responsible for the cause of a fire. We detected a lightning strike near that location around 4:00 pm.
A better chance for showers and thunderstorms is expected on Wednesday, as the cold front slowly drops in from the north. This looks to be the best chance for regionwide storms, with a few capable of producing gusty winds and locally heavy rainfall. The risk for isolated flash flooding will continue into the week, with the primary concern of poor drainage areas and urban locations. The generally dry conditions keeps the risk of river and stream flooding low across the region.
