Downpours, Extreme Heat, Humidity for Albert Pike Efforts this Week
While the odds are against another major flash flood over the Little Missouri River basin this week, there will be locally drenching thunderstorms, extreme heat and humidity plaguing recovery and cleanup operations in the Albert Pike Campground area this week.
In addition to workers fighting rough terrain and overgrown vegetation, spotty thunderstorms can bring a disruptive downpour or two.
Recall that streams in the area rose 20 feet in several hours during last Friday's deadly flash flood following 6 to 8 inches of rain. We are not likely to repeat that type of rainfall in that particular area this week.
However, there is the slight chance of a rise of several feet along the streams in the vicinity immediately following any upstream downpour.
As a result, workers will need to exercise caution, in case one of the showers becomes strong and lingers in the area for a time.
The heaviest and most persistent thunderstorm downpours in the middle Mississippi Valley will trek across Oklahoma, northwestern Arkansas and into Missouri this week.
These areas and others from the northern Texas Panhandle to Missouri to West Virginia will run the risk of major flash flooding, especially as the rounds of rain continue.
The storms in this swath are part of a lingering, long-term broad brush of drenching showers and thunderstorms fed by disturbances rolling eastward along the rim of a sea of hot and humid air anchored in the Deep South.
It is possible the atmosphere will stabilize over western Arkansas Friday into the weekend to trim the number of thunderstorms in the area greatly. However, with more sunshine and less shower activity around, temperatures will climb even higher.
High temperatures are forecast by AccuWeather.com to be well into the 90s through this weekend. The combination of the extreme temperatures, intense June sunshine, high humidity and other factors, AccuWeather.com RealFeel® temperatures will be over 100 degrees for multiple hours of the afternoon.
The system that caused the flash flooding event last week from eastern Texas to Arkansas also closed roads in West Virginia for a time this past weekend.
That particular system is now well off the Atlantic coast and out of the picture.

WeatherWhys®
People need to pay close attention to the UV index during this time of year. On a sunny day late in the spring and into the summer, the UV is usually at least an 8, which is very high. Readings over 11 are considered extreme values in which only 10 minutes of full exposure to the sun will produce a sunburn.
