Peak Heat Index Wednesday

BALTIMORE — Skies cleared out nicely Tuesday allowing high temperatures to climb close to 90 degrees. Humidity is also on the rise with oppressive conditions by the middle of the week.

High pressure shifting off the coast with southeasterly flow and a front coming down from the north will allow high heat to build across the area Wednesday and Thursday afternoons.

High temperatures on both days will be in the low to mid 90s with feel like numbers close to 100 degrees. In some locations high temperatures will be withing 3-7 degrees of their daily record highs Wednesday and at least 5-7 degrees on Thursday.

You combine the late Summer heat with oppressive humidity, and you get feel like numbers to the skin up around 95-100 degrees. With that said heat precaution protocol will be in place from proper hydration to limited times outdoors.

As a whole the year has been relatively hot and dry. So far we have had 51 days of 90 degrees or better, rivaling the most all time 90 degree days of 59 back in 2010. Besides the heat we have had a lot less rainfall compared to one year ago.

For the year at BWI Thurgood Marshall we are almost 2" below the average. For the month of September alone we are 1.21" below the average for rain, so we could use a really good soaking as brush fire season starts to kick on in. Wednesday and Thursday may be the best chance for heavy rain but at least it's something for the crispy lawns and gardens across the region.

The front that will be responsible for the rain looks to sag south Friday leading to a break in the heat and humidity but increased chances for showers across the area. These chances will continue into the first half of the weekend as more heat and humidity return. Long term stays hot and normal for precipitation the next week ahead.
