We picked up day two of 90 degrees or greater highs for August, putting us at 23 for the year. That’s a bit below average to date. Usually the threat for rain and storms tends to dwindle overnight, but we’ll have to watch a little system expected to cross the Appalachians this evening for our rain threat that begins overnight. One more day of summertime warmth and humidity tomorrow before cool air bliss arrives midweek.
Through Tonight: Skies head cloudier as the evening progresses, but it should be decent overall. Showers and thunderstorms become an increasing risk during the overnight, and it’s likely that at least some parts of the area will see rain (60% chance). Off and on activity is possible through the morning, some of which could be heavy and/or contain thunder and lightning. Lows range from the upper 60s to mid-70s.
Tomorrow (Tuesday): As the cold front heads into — and eventually through — the area, there should be some showers and storms around once again. There are questions to their coverage and the timing of the front (much of the activity may come before peak heating, minimizing the storm threat). Nonetheless, a 60% chance of rain should suffice, and some storms may be severe, particularly to our east, where the Storm Prediction Center highlights such. Highs range from the mid-80s to near 90 depending on clouds and rain. For now, I’d favor the low end.
AfPak flooding: Monsoonal storms impacting Afghanistan’s capital of Kabul killed at least 22 people in the past day. A majority died in flooding just to the north of the city when their homes or cars were swept away. This comes on the heels of flash flooding in eastern Afghanistan and parts of Pakistan that killed at least 100 people last week.
Pollen update: Ragweed season is closing in, and some is now noted in air samples. Still, weed pollen is low to moderate. Grass pollen is low and mold spores are low to moderate.
