It’s rare that changes in weather coincide exactly with changes in the calendar, but that’s the scenario we’re looking at later this week, as August tips over into September. For these last few days of August though, expect more of the same — hazy, hot and humid conditions, with a slight storm chance each afternoon. Temperatures today will reach the low 90s:
And the humidity will be high enough to push the heat index to the upper 90s:
The weekend brought numerous storms to the Midstate, but today we’re just expecting a few “radar freckles” during the hottest part of the day, as the HRRR model shows here:
More of the same tomorrow, then a slightly better storm chance on Wednesday as a cold front approaches from the north. Superficially, you’d think that a cold front moving into a hot and humid air mass would be a recipe for some active weather, but it doesn’t look like things are going to come together for anything more than a 1-in-3 storm chance. And that’s the highest storm chance in the whole 7-day forecast!
The humidity will be dropping throughout the day on Thursday, and we’ll get to enjoy some drier air for a few days.
The same “push” of dry air that will give us some relief from the humidity will also help steer the movement of a couple of tropical systems we’ll be watching this week. Right now they’re both tropical depressions, but they’re both expected to strengthen to tropical storms in the next 24 hours. (That’s when they get names — the next two names on the list are Hermine and Ian.) One storm is expected to approach the Outer Banks of North Carolina, then get pushed out to sea…the other will stay in the Gulf of Mexico for a few days, then make a right turn toward the coast of Florida:
Neither is expected to reach hurricane strength, but of course both systems will be watched carefully. The most-likely scenario for the Gulf of Mexico storm keeps its moisture away from the Midstate, so we’re unlikely to see any direct influence on our weather.
