It has been consistently warm around here lately. So far this month, every day has been at or above average. And for the month, we are averaging 90.8 degrees for our high – about 4 degrees above normal. This heat is going to intensify the next few days before we get a break later this week.
We are already at 90 degrees at 1 p.m. When you factor in the high dewpoints/humidity, it feels more like the upper 90s to near 100. The record high for today is 100. We probably won’t get quite to that record today but we have a shot at tomorrow’s record as this round of heat peaks. The current record is 97 degrees from way back in 1908. We are forecasting a high to either tie or break that record while the heat index goes to the low 100s. That’s why the National Weather Service has issued a Heat Advisory for tomorrow and a code red air quality alert is also in effect.
There is the chance for an isolated thunderstorm later today, mainly over western Maryland. Then, there could be a shower or thunderstorm tonight and again tomorrow as a cold front swings through. That front will push off to our south Wednesday, lessening any thunderstorm chance but also starting to knock the heat back down. We will probably still top out in the low 90s Wednesday before we get a break from the heat Thursday and Friday. Expect highs in the mid 80s both afternoons, possibly even staying below the average of 87 degrees.
We will be watching for another front to move our way possibly some time over the weekend.
If you have to spend any extended period of time outside or in the heat, make sure you take breaks, stay hydrated, and keep an eye on the kids, elderly and pets.
