PM Update: Heat continues; rain chances up tomorrow

We’ve tacked on another 90-degree day and we’re now cruising into the top 20% of all yearly totals with plenty of time to go to add more. Still, this is about as tolerable of a 90-degree or higher day as you’ll see during the summer here, given the breeze and a bit lower humidity levels. No weather troubles are anticipated through the overnight, but tomorrow could prove different if the ingredients come together right.

Through Tonight: Enjoying those slightly lower humidity levels? They stick with us into the evening before rising a bit again overnight as mixing winds subside. Under partly cloudy skies, lows dip to the upper 60s in the suburbs to low-and-mid 70s in urban areas.

Tomorrow (Tuesday): It’s a warm and muggy day with a decent 50% chance of showers and thunderstorms developing during the afternoon. What looked like a pretty rainy day at one point has trended drier. Still, with a potent piece of energy moving by, we run the risk of at least isolated to scattered strong to severe storms during the afternoon. Any rain could be heavy, and even cause localized flash flooding, as well. Highs should still reach the low-to-mid 90s, even with plenty of clouds, and probably some rain.

Pollen update: Susan Kosisky of Walter Reed writes, “Grass pollen is LOW at 0.32 gr/cubic meter, tree pollen is LOW at 1.6 gr/cubic meter and weed pollen is LOW at 2.24 gr/cubic meter. Mold spores are in the HIGH range at 19412.31 spores/cubic meter.”

Southern heat: Oklahoma City’s 100-degree day streak ended yesterday as the high only reached 95. But, those in the area probably aren’t taking too much solace in that considering its back well above 100 today. However, further south in Dallas, the streak lives at 38 days, and it is now nearing the all-time streak of 42 such days in 1980. Today, the National Weather Service in Dallas-Fort Worth announced that this is the warmest summer year-to-date there, besting the previous 1980 mark.
