I'm happy to report a welcome lack of weather until further notice. Today will be downright comfortable as dew points dip into the low 50s. A touch of stickiness returns by the weekend, but the weather looks downright agreeable (and quiet!) into Sunday. No drama - no wild storms, no sizzling heat. Summer the way it was probably meant to be...
Storms rumble across the state Tuesday, and a few may turn severe. Dew points in the mid-70s will make it feel like mid-90s by late afternoon. Dew points drop into the 50s tomorrow, taking the edge off the heat. Highs reach 85 to 90F the next 5 days before a stronger puff of Canadian air arrives next week. Hottest days behind us? Probably. Check the blog for more details. -Todd Nelson
Sunday was a remarkable day: bright sun, reasonable humidity levels, no wild storms, no running and screaming - I could temporarily disconnect the Doppler. Today looks dry but a round of storms may rumble overhead early Tuesday as dew points surge into the 70s. No extended Dog Days - some Canadian relief is likely by midweek.
It's July. It gets hot in July on a fairly consistent basis. Highs near 90 and a noteworthy heat index probably shouldn't come as a shock to anyone. The next 3-4 days will be uncomfortable but I do see a dip in dew point the latter half of the week. A closer look at the 7-Day, weather-related disaster declarations, and how weather radar was discovered - quite by accident.
After a thundery start Friday mellowed into a pretty nice day - beastly humid, but the biggest PM storms flared up to our east. We should enjoy a dry Saturday, an isolated thunder risk late Sunday, again Monday, but many of us will go 3 days without checking the Doppler. Some would call this the Dog Days; by early next week it will feel like 95-100F. Not exactly Dallas-hot or Atlanta-humid, but the next few days will be some of the warmest of the summer.
