Tropical Heat and Flooding Rains Return Later This Week
"Deep summer is when laziness finds respectability" wrote author and philosopher Sam Keen. I'd add my own deep thoughts if I just had the energy to get off the couch. Maybe tomorrow.
During an average summer (ha!) the atmosphere begins to stabilize in August. Longer nights cool the Earth's surface, resulting in fewer instability T-storms than June or July. In theory. On paper.
Not this year. Minnesota is precariously perched on the northern fringe of a sprawling heat bubble. Storms rippling along the U.S./Canada border yank some of this drippy, super-heated air north, resulting in spasms of heavy showers and T-storms.
According to NOAA last month was the 8th wettest July, statewide, since 1873. Many towns saw 2 to 3 times their normal rainfall last month.
Models print out another 1-2 inches of rain for the metro this week; some 3-5 inch totals possible over parts of central Minnesota by Friday. The metro area may top 90F Wednesday and Thursday before a wind shift to the northwest cools us off again by next weekend.
This summer, when in doubt, just predict rain.

Another Heat Spike. Models are suggesting a heat index in excess of 100F in the Twin Cities Thursday, largely the result of predicted dew points close to 80F. Relief comes in the form of heavy T-storms Thursday night (capable of flash flooding in some areas), followed by a cooling north to northwest breeze Friday and Saturday, dropping temperatures and humidity levels back down to tolerable levels.

Aeris Weather Briefing: Monday, August 8th, 2016
- Dangerous – potentially historic – heavy rain and flooding will continue across parts of the Gulf Coast as a slow moving disturbance works west this week.
- Totals of 3-6” have already been reported in parts of Florida through the weekend, and totals could top 8” from Louisiana to northern Florida as we head into next weekend. Places that will see heavy rain over the next several days will include Tampa, Tallahassee, Pensacola, Mobile and New Orleans.
- Numerous roads will likely be impacted as we go through the week, with road closures possible. Already some road closures have been reported in Taylor County, FL Monday morning.
Forecast Rain Into The Weekend:
Tampa, FL: 2-5”
Tallahassee, FL: 7-9”
Pensacola, FL: 9-12”
Mobile, AL: 6-8”
New Orleans, LA: 4-8”
Flash Flood Watches are also in effect for parts of northeast Georgia, North Carolina and upstate South Carolina through this evening, where heavy downpours could quickly lead to 1-3” of rain across the region. Some local 4-6” totals are possible.
Summary. Heavy rain will continue across parts of the Gulf Coast as we head through the work week due to a slow moving disturbance. Already 3-6” of rain has fallen this weekend across parts of Florida, and areas from New Orleans into northern Florida could easily end up with at least 8” of rain through the end of this week. This heavy rain will likely cause flooding and road issues across the region. Facilities across these areas that normally experience problems during flash flood scenarios should continue to be on alert for issues over the next few days.
