Monitoring the threat for severe weather
MM’s Wx Vlog
Today’s Afternoon Wx Map
A warm front lifts north into the Ohio River Valley today, while another warm front gathers strength near the coast. The main concern is that developing cold front over Kansas that will bring us strong storms Friday night and Saturday morning.
Local Seven-Day Forecast
Thursday: Partly to mostly cloudy. Windy.
Friday: Mostly cloudy, with scattered showers and thunderstorms developing. Windy.
A few storms may be severe Friday night. Heavy rainfall is also possible.
Saturday: Rain & storms likely, especially before noon. Some storms could be strong. Windy. Rain tapers off by evening as temperatures drop.
Sunday: Mostly sunny. Cooler.
Monday – Wednesday: Mostly sunny. Warmer. Very nice for this time of year!
MM’s Wx Concerns
Another strong storm system could bring heavy rainfall and the threat of strong storms from Friday to Saturday. Strong southerly winds could also prompt wind advisories. I’ll keep a close eye on all of this.
Strong, southerly winds will be increasing today and getting stronger through Saturday ahead of our next storm system. Be prepared for sporadic power outages that we often see with these wind events. Make sure those holiday decorations are secure! The wind can be a real Grinch! 🙂 Winds should subside by Saturday night.
Concern is increasing for storms Friday night and early Saturday morning. I’ll get more specific with timing as we near the event. Go ahead and start preparing now for severe storms during this time period.

On This Day in Wx History
1917- It’s a cold day in Middle Tennessee. Clarksville sees the mercury plunge to -12 degrees, which sets a new record low for December. Other readings include Crossville Experiment Station, -11, McMinnville, -1, and Nashville, 0.
The next MM Kids class will be Tuesday, December 14, at 4:00 pm at TCAT. Suggested age range is 8 yrs and up.
NOTE: Class is nearly full!
This hour-long class focuses on weather folklore. We’ll discuss what works and what doesn’t and why. We’ll also discuss just how complex our planet’s atmosphere is and what that means for folklore. A hands-on activity will make the lesson come to life! Sign up at https://docs.google.com/forms/d/e/1FAIpQLSeJd9uESXEQKxIxF07Hk0BxcDaCsCpxWHVceM-YqtZzww7y7Q/viewform
The data cutoff for Drought Monitor maps is each Tuesday at 7 a.m. The maps, which are based on analysis of the data, are released each Thursday at 7:30 a.m.

Summary by the US Drought Monitor at the University of Nebraska
This U.S. Drought Monitor (USDM) week saw continued deterioration in conditions across areas of the Mid-Atlantic (Virginia, North Carolina) and the Southeast (South Carolina, Georgia) in response to below-normal precipitation (past 30- to 90-day period), declining soil moisture and streamflow levels. Likewise, drought-affected areas expanded and intensified on the map in areas of the South including Louisiana, Arkansas, and Texas as well as in the Southern Plains of Oklahoma, where overall warm and dry conditions have prevailed during the past 30- to 120-day period. Across areas of the Northern Plains, Upper Midwest, and the Northeast, light-to-heavy snowfall accumulations were observed during the past week. The heaviest accumulations (8-18 inches) were centered on northern portions of Minnesota, Wisconsin, and Michigan, while lake-effect snowfall (2 to 8 inches) impacted areas downwind of Lake Erie and Lake Ontario in New York, according to snowfall analysis from the National Weather Service (NWS) National Operational Hydrologic Remote Sensing Center (NOHRSC). Out West, some areas including the North Cascades, Sierra Nevada, and the Northern and Central Rockies, received much-needed snowfall this past week. However, basin-level snowpack conditions remained below normal across the entire western United States. In Hawaii, a Kona Low delivered very heavy rainfall accumulations (highest totals exceeding 16+ inches) leading to widespread flooding, power outages, and damage to infrastructure in areas across the Hawaiian Island this week. Impacts from the multi-day event led Hawaii Governor Ige to declare a state of emergency on December 6. With the meteorological autumn (September-November) coming to a close, the Lower 48 experienced its third warmest fall on record with the largest mean temperature departures from average observed across areas of the Northern and Central Plains, according to NOAA’s National Centers for Environmental Information (NCEI). In terms of fall precipitation, the driest conditions were observed across parts of the Southwest, Texas, Montana, Wisconsin, and the Carolinas.
Estimated Population in Drought Areas in the US: 96,501,580
Estimated Population in Drought in the South: Last Week: 8,608,590 This Week: 12,352,977
Tennessee’s drought areas increased, especially across West Tennessee.
