MM’s Wx Concerns
Strong, southerly winds will be increasing today and getting stronger overnight and into Saturday morning. Some gusts could hit 40 mph. 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 Saturday night.
Any storm that develops in this environment will be capable of becoming severe. The main threat, however, appears to come in the timeframe of 5:00 a.m. Saturday to noon Saturday. Please stay tuned for changes to timing!

MM News
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 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!
Drought Monitor
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.
This is the latest map and info, released today!
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
