Summer weather is coming in hot across the northeastern United States. A strong high-pressure system is building across the Midwest and is expected to move into place over the northeastern United States for the rest of the weekend into next week. This high pressure settling over the area will allow for very high daytime temperatures ranging from the low to mid-90s and perhaps even triple digits in some inland locations. The heat index is expected to be in the low to mid triple digits. The heat index is a measure of how hot it is outside when you factor in the relative humidity with the actual air temperature. For much of the northeast, local National Weather Service offices have issues heat advisories and excessive heat warnings. Cities across the northeast could meet or exceed all-time record highs during this heat wave.
The definition of a heat wave according to the National Weather Service, is a period of abnormally and uncomfortably hot and humid weather that typically lasts two or more days. Many cities across the Northeast are likely to meet these criteria as high pressure sits over the region. This high pressure system will bring in a hot and humid air mass due to the advection of warm air from the south. The hot and humid weather is expected to linger in the region throughout the weekend and into early next week.
When temperatures are this hot and the humidity is in the low to mid-70s or higher, the body has a harder time regulating its body temperature. This is due to the fact that the evaporation process is slowed down. It is important to keep in mind simple safety tips. Wear loose, light fitting clothing and be sure to limit outdoor activity during the hottest part of the day. If you do need to be outside, be sure your skin is protected from the sun and stay hydrated. If you do not have air conditioning, seek out local community resources like the library or a community center to take a break in. Check your local parks and recreation schedules to see if pools and state beaches are open for extended hours. Remember to never leave children or pets alone in a closed vehicle, as it can be lethal to them. Temperatures can rise quickly in a very short amount of time in a vehicle with the windows rolled up. Avoid high-energy activities and if you need to exercise outdoors try to work during the early morning or late evening when temperatures are cooler. Finally, make sure to check on the elderly or anyone who is sensitive to these dangerous temperatures.
